Top 5 Natural Appetite Suppressants to Help Lose Weight …

Posted: February 16, 2019 at 2:43 am

No doubt about it, overeating and its connection to more and more people becoming overweight or obese is one of the most complex and challenging issues in health care today. There are many reasons why you might feel like youre always hungry, including nutrient deficiencies, a lack of fiber or healthy fats in your diet, fatigue, or high amounts of emotional stress. However, it doesnt have to be this way. Natural appetite suppressants can help you achieve satiety and avoid overeating, and they can help you do that without the dangers of diet pills.

While manufacturers of weight loss pills continue to promote the convenience and rapid results associated with their products, the U.S. Food and Drug Administrationand other health authorities warn against their use. Some of the main reasons that appetite-suppressing weight loss pills are considered to be at least somewhat dangerous include medication interactions, tainted or unlisted ingredients, high amounts of caffeine, and fillers or synthetic additives that causenegative reactions, just to name few.

The good news is this: There appear to be safer and more natural options for suppressing your appetite (and potentially losing some weight as a result) without so much risk involved. In fact, throughout history cultures all over the world have consumed natural foods, teas and spices that are now provingto be beneficial for metabolic functions and energy expenditure. Consuming natural appetite suppressants, such as filling, fat-burning foods, nutrients likeconjugated linoleic acid andchromium, probiotics, and anti-aging beverages like green tea, can help you keep mindless cravings, a habit of snacking or a sweet tooth under better control.

Appetite suppressants are either pills, drinks, supplements or whole foods that help keep you from overeating. Natural appetite suppressants which have some similarities to commercial weight loss pills but some important differences may help tackle some of these issues related to obesity or emotional eating in part by balancing levels of hunger hormones, such as ghrelin and leptin. Ghrelin and leptin rise and fall throughout the day depending on things like how much youve recently eaten, your mood, stress level, sleep, genetics, current weight and level of inflammation. In other words, theres a lot at play when it comes to suppressing or stimulating your daily appetite.

In addition to decreasing your appetite through hormone regulation, nutrients or essential oils used for safely promoting weight loss can help tip the scale in your favor in several other ways, such as burning more stored body fat for energy (these are known as thermogenics), improvingbalance of blood sugar levels, curbing cravings for junk foods or sweets, improving thyroid health, increasing release of happy hormones or endorphins like serotonin, and possibly giving you a bit more energy throughout the day to be used for extra physical activity.

There are all sorts of products available today that claim to have these appetite-dulling effects, but not every kind has been shown to work or even to be very safe. Examples of weight loss supplements that pose the most risks include guarana, garcinia cambogia, bitter orange or ephedrine.According to the FDA, Supplements arent considered drugs, so they arent put through the same strict safety and effectiveness requirements that drugs are. (1) Thats why I recommend approaching weight loss holistically especially by eating filling, fat-burning, natural foods and other natural appetite suppressants that wont potentially lead to complications like taking pills or consuming high amounts of caffeine can.

1. Green Tea Extract

Green tea has been consumed for thousands of years and is still one of the healthiest beverages available to us today. Its been the focus of hundreds of studies related to everything from preventing cognitive disorders like dementia to managing metabolic dysfunction. Recently, certain antioxidants and substances in green tea extract have been tied to beneficial effects on metabolic diseases and improvements in regulating appetite hormones.

A Cochrane meta-anylsis including 14 studied involving use of green tea found that its consumption was associated with mild but significant weight loss results compared to controls or placebo. (2) One study that tested the effects of green tea extract on a group of adults compared to a control group not taking green tea found that after 12 weeks, those taking 857 milligrams of green tea had significantly lower levels of ghrelin (known as the hunger hormone).

Participants in the green tea extract group also had improvements in cholesterol levels and elevated levels of adiponectin compared to the placebo group. Low levels of adiponectin have been tied to problems like insulin resistance, metabolic syndrome and increased inflammation. EGCG, the most abundant green tea catechin and a powerful bioactive constituent, has also been shown to act like a cancer-fighting compound and promote thermogenic activities in studies, therefore decreasing fat cell proliferation and helping burn body fat for energy. (3)

Although not every study has shown such strong and positive weight loss results associated with green tea extract, it seems safe for most adults to take up to 800900 milligrams daily, usually spread out over three increments. (4) Although theyre generally rare, when taking green tea extract be on the lookout for reported adverse effects thatmight include mild headaches, signs of hypertension, constipation or possibly increased symptoms of urinary tract infection.

2. Saffron Extract

Some research suggests that taking certain saffron extracts can positive effects on mood regulation by increasing endorphin and serotonin levels. Saffrons effects when it comes to suppressing appetite, including leading to reduced snacking and an elevated mood, seem to be the result of increased serotonin action in the body. (5) This has been shown to help improve symptoms of depression, emotional eating and PMSafter about six to eight weeks of treatment. In fact, certain studies have found that saffron extract can work almost as well as taking a low-dose prescription antidepressant drug (such as fluoxetine or imipramine).

Additionally, while research shows mixed results, theres some evidence that taking a chemical from saffron called crocetin might decrease fatigue during exercise and help with increasing energy expenditure. (6) To get theantidepressant benefits of saffron, start with the the standard daily dose of 30 milligrams, used for up to eight weeks. If you have any existing condition that might interfere with saffrons influence on serotonin metabolism (like depression, for example), its a good idea to get your doctors opinion first.

3. Grapefruit Essential Oil

Grapefruits benefits for weight losshave been the focus of dozen of studies and seem to be due to beneficial acids, antioxidants, volatile oils and enzymes that help reduce your appetite, lower cravings, help stimulate the lymphatic system and give you a mild dose of uplifting energy.

Research regarding grapefruits effects on olfactory stimulation (how smelling the aroma affects the central nervous system) shows that inhaling the fruits smell can positively alter autonomic nerve signaling, lipolysis (fat metabolism) and appetite regulation. Here are several findings from a number of studies about how grapefruit essential oil impacts appetite and body weight: (7, 8)

Certain studies have shown that just three 15-minute exposures to grapefruit essential oil each week helped participants reduce their appetites and practice habits (like slow, mindful eating) that better control their weight.How can you use grapefruit essential oil at home or when youre on the go? Trying adding several drops of pure grapefruit essential oil (citrus paradise) either to a diffuser in your office/home, to your shower or bath soap, or with a carrier oil to be massaged right onto your skin (just do a skin patch test to be sure you dont have an allergic reaction first).

4. Foods High in Fiber

Dietary fibers, whether from food sources or in concentrated supplement form, have been used for hundreds of years to promote fullness, improve gut healthand digestive functions, and help maintain strong immunity and heart health. Despite the fact that fiber intake is inversely associated with hunger, body weight and body fat, studies show that the average fiber intake of adults in the United States is still less than half of recommended levels. (9)

What is it about fiber that dulls your appetite?Because fiber is not able to be digested once consumed, plus it absorbs so much of its own weight in water, high-fiber foods help slow your bodys digestion of glucose (sugar), keep you feeling fuller for longer and beat cravings. Many foods high in fiber are also very nutritionally dense, meaning you get more bang for your nutritional buck and help prevent dehydration or deficiencies.

Eating a high-fiber diet similar to the Mediterranean dietor the way that those known for longevity living in theBlue Zones eat has been linked to a longer life span, better regulation of healthy body weight, improved gut/digestive health, hormonal health and much more. According to researchin the Obesity Reports, Evidence points to a significant association between a lack of fiber intake and: ischemic heart disease, stroke, atherosclerosis, type 2 diabetes, overweight and obesity, insulin resistance, hypertension, dyslipidemia, as well as gastrointestinal disorders. (10)

To fill up on the right foods faster and for longer,consume more high-fiber foods, including chia seeds, flaxseeds, starchy or non-starchy fresh veggies, beans or legumes, and fruit (especially berries).

5. Spicy Foods

Naturally spicy (plus anti-inflammatory) ingredients like cayenne, black pepper, curry, turmeric, ginger, dandelion or cinnamon might help increase your bodys ability to burn fat, suppress hunger levels, normalize glucose levels, reduce free radical damage associated with aging and reduce your appetite for sweets.

Studies have found that results associated with eating spices like cayenne with high-carb meals indicate that red pepper increases diet-induced thermogenesis (heating the body and burning of fat) and lipid oxidation. (11) Other research regarding the effects of capsaicin, the phytochemical responsible for the spiciness of peppers, has shown that this compound can modulate metabolic activities through affecting transient receptors in the digestive system, such as one called TRPV1.

Because theyre loaded with benefits, virtually free from calories and easy to use on all sorts of recipes, theres basically no reason for anything but love for spices.Theres evidence that including more spices and herbs in your diet (especially turmeric, black pepper and cayenne pepper) can help you reduce intake of things like flavor enhancers, salt and sugar while helping you reduce weight gain without having negative effects. Try adding some to homemade tea or detox drinks, marinades, on top of fish or other proteins, in a stir-fry, on veggies, or in soups.

Commercially sold diet pills usually contain a mix of stimulants, including caffeine, herbs, and sometimes digestive enzymes or acids. Generally, they come with adverse side effects, making them unhealthy ways to lose weight.

Caffeine is one of the most common weight loss ingredients because it often has the appealing effects of dulling someones appetite, improving motivation and increasing energy for activity. However, as you may have experienced yourself in the past, consuming too much caffeine within a short time period can cause strong side effects like jitteriness, headaches, insomnia, anxiety, heart palpitations, diarrhea and more.

While the majority of adults worldwide consume at least some caffeine daily, mostly in the form of coffee or tea, abnormally high amounts of caffeine are usually limited to fat-burning supplements. When weight loss pill manufacturers include caffeine in amounts theyre rarely used otherwise, its likely to cause both short-term issues like dependence and jitteriness or, even worse, dangerous interactions with existing medical conditions or medications.

Due to interactions with medications or changes in blood pressure, other side effects of popular weight loss pills like guarana, garcinia cambogia or ephedrine, for example can include anxiety, trouble sleeping, indigestion, diarrhea, rapid heartbeat, headaches, dependency and blood pressure changes that can sometimes be dangerous.

Some commercially available thermogenic supplements (especially those containing ephedrine, also called ephedra) have even been found to induce acute liver failureand contribute to serious reactions likeexcessive bleeding, increased pressure in the brain, fatigue, malaise and jaundice.(12) This is one reason why ephedrine is nowbanned as a dietary supplement ingredient in the U.S. due to an increase in reported reactions hypertension, palpitation, stroke, seizures, heart attack and even in rare cases death.

Because theres always the risk for developing many different reactions depending on your current health and age, pay attention to how you feel even when using natural appetite suppressants. Follow dosage directions carefully, since high doses can cause dangerous reactions like poisoning, yellow appearance of the skin or mucous membranes, vomiting, dizziness, diarrhea, and heart problems.

Generally speaking, not enough is known about the safety of using even natural appetite suppressants during pregnancy or breastfeeding, so to stay on the safe side its wise to avoid use of supplements mentioned above during these times. Children and the elderly should also generally avoid consuming too much caffeine or supplements without a doctors opinion first.

If you have any of the below health problems, talk to a professional before attempting to suppress your appetite for weight loss (especially if you take medications daily):

Heres the bottom line on using natural appetite suppressants compared to other appetite suppressants: While weight loss pills, teas or other products may possibly give you a lift in energy, dulled appetite or temporarily elevated mood, theyre unlikely to result in any long-term weight loss, especially when you dont make other healthy lifestyle changes. Focus on eating a well-rounded, nutrient-dense diet, preventing deficiencies in key vitamins or minerals, and staying active. Then you shouldnt need to turn to weight loss products in the first place.

Excessive screen time cause childhood obesity

The average 8- to 18-year-old spends more than seven hours a day fixated on a screen, whether it's a computer, smartphone, tablet, video game or TV, the latest evidence shows. Teenagers who exceed two hours daily of recreational screen time are nearly twice as likely to be overweight or obese, the review showed. Excessive TV viewing is associated with many disease risks and is associated with numerous risk factors, including poor diet, lower socio economic status, obesity, smoking or depressive symptoms. As we can see, mass media may cause overweight and obesity in adult men, children, and adolescents.

Is the Ketogenic Diet Safe Long Term? Potential Dangers to …

Posted: February 13, 2019 at 6:44 pm

Every diet designed to help you live a healthier and better life each has their own specific rules and promised outcomes. One diet that has constantly been gaining popularity, with several people backing its credibility, is the Ketogenic (Keto) Diet.

Keto Diet focuses on eating low to no carb meals to force your body into a state of ketosis.

Ketosis is when ketone molecules, which come from your bodys stored fat, are released and build up in your bloodstream.

In the absence of blood sugar that come from carbohydrates, the cells in your body would turn to using the ketone bodies to create and generate energy.

Youre usually able to get into ketosis within two to four days.

Because the body uses up the stored fat instead of blood sugar to generate energy, there are several benefits tied to practicing the Keto diet such as:

Aside from these benefits, Keto diet promises quicker and severe weight loss. Because the body adapts to using stored fat as energy sources, fat loss from abdominal cavity takes place.

Being under the Ketogenic diet need supervision and maintenance.

Maintaining your body in ketosis (learn more about it here) state can be helped in three ways:

One misconception tied to the Keto diet is that you can eat a high amount of protein intake, meaning steaks and roasted chicken.

However, your body can break down the protein you put into your system and turn it into fuel, putting aside the stored fat you want your body to burn.

You must keep a balanced diet of less protein and more healthy fats so your body will use up the fats and ketones to generate energy.

You cant eat bread if you want to go keto!

Observing the Keto diet doesnt necessarily mean that you have to give up your carbs entirely. Most things I have read, suggest trying to stick to 20 grams of carbs per day if you want to reach and maintain ketosis.

You can have a low-carb keto diet, where you keep track of all your carb intake. If you eat carbs, you must take a very high intake of healthy fats along with it.

However, it would be a challenge to eat and monitor your carb intake once you successfully achieve ketosis.

There are several do-it-yourself testing products that are made to assess your ketone levels. Pretty much like a pregnancy test stick, ketone levels can be tested using urine sticks, breath meter, and blood extraction.

Many Native Americans live their lives in a permanent state of ketosis and their population did not drop due to it.

So I guess it is safe to say that Ketogenic diet is safe to practice for a very long time.

Keto therapy is also used for children with epilepsy and is known to reduce the frequency and intensity of seizures.

Many of these children stay under the Keto diet for as long as 12 years.

So aside from its physical benefit outcomes, it also has a genuine effect on people with this serious illness.

A recent study also showed and proved that staying under the Ketogenic diet for 10 years is safe and healthy. The study proved that there are no cardiovascular risks that are tied up with people who undergo the Keto diet.

These people were watched for 10 years and were sent to medical assessments to observe and evaluate the possible effects on their body and overall health.

There are some people who are not fit to observe and practice the Keto diet, such as people who have diabetes or are acidic and alcoholics.

The risk of having a diet that has high-protein and low carb can also affect people who suffer from osteoporosis, have kidney problems, and people who generally have high cholesterol.

These people could potentially have major health complications. Anyone who undergoes the Keto diet must keep being observant with the effects it has on their bodies and emotional states.

However, there are no known health complications that are brought about by Ketogenic diet, but some doctors caution that more research needs to be done before knowing for sure.

Keto is on the strictest end of the low carb diet plans, and thats because you pretty much eliminate sugar, and keep your carbs to around 20 grams per day.

There are some other low carb diets out there that work well too, and arent quite as strict as keto.

The Atkins plan has some less strict options that you can follow now, and the South Beach Diet is another decent alternative (see how it compares to keto here).

If youre wanting to keep maximum fat burning results, though, then the ketogenic is the best diet I have tried. Thats in terms of the amount of weight you can lose in a very short amount of time.

There are a lot of different reviews out there, but if you browse the Reddit forums at all, you can find some pretty incredible success stories. These are great to see some of the results that people have achieved, but also to help get you motivated!

Before you throw out everything in your pantry that has sugar and high carb content and start filling your freezer with nothing else but high-fat foods and protein, you might want to do a test run if the Ketogenic diet is the right diet for you.

As with other diets, Keto also has its distinct set of disadvantages, making it a less than ideal option for people who have certain health issues.

*You should consult with your physician first before starting your journey with the Ketogenic diet as it can be counterproductive in terms of boosting your overall health and wellness, and you want to make sure that you are healthy enough for an extremely low-carb diet, like keto.

Testosterone Hormone Replacement Therapy – Metro MediSpa

Posted: February 13, 2019 at 1:42 am

In males, testosterone begins to decline about the time they reach 40. By middle age as much as 30% of men will have a level that qualifies as low; between ages 70 and 80, the percentage with low testosterone rises to 70%.

The period of time a man experiences low testosterone (Low-T) is referred to andropause, often thought of as similar to menopause in women. The andro name is derived from the class of hormones testosterone belongs to: Androgens.

Androgen deficiencies are related to common health issues such as obesity, diabetes and insulin malfunctions, high blood pressure and hardening and/or blocking of the arteries. Other issues are elevations in total cholesterol, and LDL, or the bad cholesterol and triglycerides. Androgens are believe to protect mens arteries from atherosclerosis; evidence is emerging that androgen therapy can partially reverse the progression of blockage and hardening in testosterone-deficient males.

Hypogonadism is the medical term for low testosterone with specific symptoms and indicators, including:

Saliva and/or blood tests can measure testosterone levels and hypogonadism sufferers can be treated with hormone therapy. Hormone therapy is also often indicated for men with high estrogen levels and low total testosterone.

TRT (testosterone replacement therapy) is well tolerated by most and can improve the quality of life as well as eradicate related symptoms for many men.

Cardiovascular risk factors also can be positively impacted by TRT, according to findings in a recent study. One popular method of applying testosterone, in a cream used on the skin, can allow adequate amounts to be absorbed, thus mimicking normal daily production.

A healthy lifestyle comes with higher hormone levels, and higher hormone levels generally produce a more active lifestyle.

Male hormone replacement can produce optimum results when combined with other indicated supplements, healthy nutrition and appropriate exercise, all part of a balanced anti-aging problem we offer.

Feel Better with TRT and Get Back in the Game!

We hear a lot about the changes caused by menopause in women, but much less about andropause (so called manopause) or low testosterone in men. Young men in their late teens and twenties seem to have boundless energy driven by high testosterone levels, but that doesnt last. Testosterone levels drop about one percent a year after age 30 and many men experience an even steeper decline. This steady drop in testosterone can lead to a need for Testosterone Replacement Therapy (TRT).

Physical signs of declining testosterone (low T) include decreased muscle strength and size, increased fat- especially belly fat, loss of body hair, dry eyes, elevated blood pressure, thinning dry skin, enlarging fatty breasts (gynecomastia), and lack of body odor.

The Adam Questionaire is a sensitive tool for screening for low T. A decrease in sex drive or erectile dysfunction suggest low T. Other symptoms include decreased energy or strength, decreased enjoyment of life, sadness or grumpiness, falling asleep after dinner, or a recent deterioration in work performance.

Fortunately, most men can be restored to hormonal health with proper medical care. The benefits of testosterone replacement therapy (TRT) include increased energy and strength, increased muscle mass, decreased osteoporosis, improved cholesterol profile, lowered blood sugars, improved sexual function, and increased longevity.

Men experiencing the symptoms of low T need a focused medical history, physical exam, and laboratory testing by a physician with specialized training in TRT. Although testosterone may be replaced by transdermal gels or implanted pellets, most patients are best managed by self administered injections of bioidentical testosterone and HCG (human chorionic gonadotropin). Some men may also need estrogen blocking pills.

The good news is that many of these negative symptoms are not really from aging at all, but rather from low testosterone. You can improve your health and recapture the joy and vigor of life.

TRT is safe if appropriately prescribed and monitored. There is no evidence that testosterone causes cancer, however preexisting prostate cancer may grow faster with TRT. It is very important to have a prostate exam and a serum PSA (prostatic specific antigen) level prior to beginning therapy, and to monitor the PSA level regularly.

You may very well start feeling better within days. However, body composition changes will transform over several months as your testosterone (T) level is optimally tuned. Several patients have already reported weight loss and lean muscle gain within the first month. They have have also reported increased erection strength, better sex drive, and an overall uptick in energy.

Male breast enlargement (gynecomastia) is a sign of testosterone/estrogen imbalance. Patients with this problem may need an estrogen blocker in addition to TRT. Therapy does not reverse the enlargement, but often Laser Assisted Liposuction can correct it very nicely.

The Laser Center of Maryland proudly provides Baltimore, Annapolis, Columbia, Severna Park, Glen Burnie and Pasadena, Maryland with comprehensive and advanced laser surgery and cosmetic surgery.

Dieting – Wikipedia

Posted: February 10, 2019 at 9:40 pm

Dieting is the practice of eating food in a regulated and supervised fashion to decrease, maintain, or increase body weight, or to prevent and treat diseases, such as diabetes. A restricted diet is often used by those who are overweight or obese, sometimes in combination with physical exercise, to reduce body weight. Some people follow a diet to gain weight (usually in the form of muscle). Diets can also be used to maintain a stable body weight and improve health.

Diets to promote weight loss can be categorized as: low-fat, low-carbohydrate, low-calorie, very low calorie and more recently flexible dieting.[1] A meta-analysis of six randomized controlled trials found no difference between low-calorie, low-carbohydrate, and low-fat diets, with a 24 kilogram weight loss over 1218 months in all studies.[1] At two years, all calorie-reduced diet types cause equal weight loss irrespective of the macronutrients emphasized.[2] In general, the most effective diet is any which reduces calorie consumption.[3]

A study published in American Psychologist found that short-term dieting involving "severe restriction of calorie intake" does not lead to "sustained improvements in weight and health for the majority of individuals".[4] Other studies have found that the average individual maintains some weight loss after dieting.[5] Weight loss by dieting, while of benefit to those classified as unhealthy, may slightly increase the mortality rate for individuals who are otherwise healthy.[6][7][8]

The first popular diet was "Banting", named after William Banting. In his 1863 pamphlet, Letter on Corpulence, Addressed to the Public, he outlined the details of a particular low-carbohydrate, low-calorie diet that had led to his own dramatic weight loss.[9]

One of the first dietitians was the English doctor George Cheyne. He himself was tremendously overweight and would constantly eat large quantities of rich food and drink. He began a meatless diet, taking only milk and vegetables, and soon regained his health. He began publicly recommending his diet for everyone suffering from obesity. In 1724, he wrote An Essay of Health and Long Life, in which he advises exercise and fresh air and avoiding luxury foods.[10]

The Scottish military surgeon, John Rollo, published Notes of a Diabetic Case in 1797. It described the benefits of a meat diet for those suffering from diabetes, basing this recommendation on Matthew Dobson's discovery of glycosuria in diabetes mellitus.[11] By means of Dobson's testing procedure (for glucose in the urine) Rollo worked out a diet that had success for what is now called type 2 diabetes.[12]

The first popular diet was "Banting", named after the English undertaker William Banting. In 1863, he wrote a booklet called Letter on Corpulence, Addressed to the Public, which contained the particular plan for the diet he had successfully followed. His own diet was four meals per day, consisting of meat, greens, fruits, and dry wine. The emphasis was on avoiding sugar, sweet foods, starch, beer, milk and butter. Bantings pamphlet was popular for years to come, and would be used as a model for modern diets.[13] The pamphlet's popularity was such that the question "Do you bant?" referred to his method, and eventually to dieting in general.[14] His booklet remains in print as of 2007.[9][15][16]

The first weight-loss book to promote calorie counting, and the first weight-loss book to become a bestseller, was the 1918 Diet and Health: With Key to the Calories by American physician and columnist Lulu Hunt Peters.[17]

Low-fat diets involve the reduction of the percentage of fat in one's diet. Calorie consumption is reduced because less fat is consumed. Diets of this type include NCEP Step I and II. A meta-analysis of 16 trials of 212months' duration found that low-fat diets (without intentional restriction of caloric intake) resulted in average weight loss of 3.2kg (7.1lb) over habitual eating.[1]

Low-carbohydrate diets are relatively high in protein and fats. Low-carbohydrate diets are sometimes ketogenic (i.e., they restrict carbohydrate intake sufficiently to cause ketosis).

Low-calorie diets usually produce an energy deficit of 5001,000 calories per day, which can result in a 0.5 to 1 kilogram (1.1 to 2.2 pounds) weight loss per week. One of the most commonly used low-calorie diets is Weight Watchers. The National Institutes of Health reviewed 34 randomized controlled trials to determine the effectiveness of low-calorie diets. They found that these diets lowered total body mass by 8% in the short term, over 312 months.[1] Women doing low-calorie diets should have at least 1,000 calories per day and men should have approximately 1,200 calories per day. These caloric intake values vary depending on additional factors, such as age and weight.[1]

Very low calorie diets provide 200800 calories per day, maintaining protein intake but limiting calories from both fat and carbohydrates. They subject the body to starvation and produce an average loss of 1.52.5kg (3.35.5lb) per week. "2-4-6-8", a popular diet of this variety, follows a four-day cycle in which only 200 calories are consumed the first day, 400 the second day, 600 the third day, 800 the fourth day, and then totally fasting, after which the cycle repeats. These diets are not recommended for general use as they are associated with adverse side effects such as loss of lean muscle mass, increased risks of gout, and electrolyte imbalances. People attempting these diets must be monitored closely by a physician to prevent complications.[1]

Detox diets are promoted with unsubstantiated claims that they can eliminate "toxins" from the human body. Many of these diets use herbs or celery and other juicy low-calorie vegetables.

Religious prescription may be a factor in motivating people to adopt a specific restrictive diet.[18] For example, the Biblical Book of Daniel (1:2-20, and 10:2-3) refers to a 10- or 21-day avoidance of foods (Daniel Fast) declared unclean by God in the laws of Moses.[18][19] In modern versions of the Daniel Fast, food choices may be limited to whole grains, fruits, vegetables, pulses, nuts, seeds and oil. The Daniel Fast resembles the vegan diet in that it excludes foods of animal origin.[19] The passages strongly suggest that the Daniel Fast will promote good health and mental performance.[18]

Fasting is practiced in various religions. Examples include Lent in Christianity; Yom Kippur, Tisha B'av, Fast of Esther, Tzom Gedalia, the Seventeenth of Tamuz, and the Tenth of Tevet in Judaism.[20] Muslims refrain from eating during the hours of daytime for one month, Ramadan, every year.

Details of fasting practices differ. Eastern Orthodox Christians fast during specified fasting seasons of the year, which include not only the better-known Great Lent, but also fasts on every Wednesday and Friday (except on special holidays), together with extended fasting periods before Christmas (the Nativity Fast), after Easter (the Apostles Fast) and in early August (the Dormition Fast). Members of The Church of Jesus Christ of Latter-day Saints (Mormons) generally fast for 24 hours on the first Sunday of each month. Like Muslims, they refrain from all drinking and eating unless they are children or are physically unable to fast. Fasting is also a feature of ascetic traditions in religions such as Hinduism and Buddhism. Mahayana traditions that follow the Brahma's Net Sutra may recommend that the laity fast "during the six days of fasting each month and the three months of fasting each year" [Brahma's Net Sutra, minor precept 30]. Members of the Baha'i Faith observe a Nineteen Day Fast from sunrise to sunset during March each year.

Weight loss diets that manipulate the proportion of macronutrients (low-fat, low-carbohydrate, etc.) have been shown to be no more effective than diets that maintain a typical mix of foods with smaller portions and perhaps some substitutions (e.g. low-fat milk, or less salad dressing).[21] Extreme diets may, in some cases, lead to malnutrition.

The Dietary Guidelines for Americans is a set of recommendations about a healthy diet written for policy makers, nutrition scientists, and dieticians and other clinicians, produced by the US Department of Agriculture, in concert with the US Department of Health and Human Services and quintannually-revised. The current guidelines are written for the period 2015 - 2020 and were used to produce the MyPlate recommendations on a healthy diet for the general public.

One of the most important things to take into consideration when either trying to lose or put on weight is output versus input. It is important to know the amount of energy your body is using every day, so that your intake fits the needs of one's personal weight goal. Someone wanting to lose weight would want a smaller energy intake than what they put out. There is increasing research-based evidence that low-fat vegetarian diets consistently lead to healthy weight loss and management, a decrease in diabetic symptoms[22] as well as improved cardiac health.[23]

When the body is expending more energy than it is consuming (e.g. when exercising), the body's cells rely on internally stored energy sources, such as complex carbohydrates and fats, for energy. The first source to which the body turns is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate, 65% of which is stored in skeletal muscles and the remainder in the liver (totaling about 2,000 kcal in the whole body). It is created from the excess of ingested macronutrients, mainly carbohydrates. When glycogen is nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy. In this process, fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which can be used to generate energy.[24] The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system.

Some weight loss groups aim to make money, others work as charities. The former include Weight Watchers and Peertrainer. The latter include Overeaters Anonymous and groups run by local organizations.

These organizations' customs and practices differ widely. Some groups are modelled on twelve-step programs, while others are quite informal. Some groups advocate certain prepared foods or special menus, while others train dieters to make healthy choices from restaurant menus and while grocery-shopping and cooking.

A 2008 study published in the American Journal of Preventive Medicine showed that dieters who kept a daily food diary (or diet journal), lost twice as much weight as those who did not keep a food log, suggesting that if you record your eating, you would be more aware of what you eat and, therefore you wouldn't eat as many calories.[25]

A 2009 review found that existing limited evidence suggested that encouraging water consumption and substituting energy-free beverages for energy-containing beverages (i.e., reducing caloric intake) may facilitate weight management. A 2009 article found that drinking 500ml of water prior to meals for a 12-week period resulted in increased long-term weight reduction. (References given in main article.)

Fasting is when there is a long time interval between the meals. In dieting, fasting is not recommended, instead, having small portions of food after small intervals is encouraged. Lengthy fasting can also be dangerous due to the risk of malnutrition and should be carried out only under medical supervision. During prolonged fasting or very low calorie diets the reduction of blood glucose, the preferred energy source of the brain, causes the body to deplete its glycogen stores. Once glycogen is depleted the body begins to fuel the brain using ketones, while also metabolizing body protein (including but not limited to skeletal muscle) to be used to synthesize sugars for use as energy by the rest of the body. Most experts believe that a prolonged fast can lead to muscle wasting, although some dispute this. The use of short-term fasting, or various forms of intermittent fasting have been used as a form of dieting to circumvent this issue.

While there are studies that show the health and medical benefits of weight loss, a study in 2005 of around 3000 Finns over an 18-year period showed that weight loss from dieting can result in increased mortality, while those who maintained their weight fared the best.[6][8][26] Similar conclusion is drawn by other studies,[6][27] and although other studies suggest that intentional weight loss has a small benefit for individuals classified as unhealthy, it is associated with slightly increased mortality for healthy individuals and the slightly overweight but not obese.[7] This may reflect the loss of subcutaneous fat and beneficial mass from organs and muscle in addition to visceral fat when there is a sudden and dramatic weight loss.[8]

Low-carbohydrate and low-fat diets perform similarly in the long term as weight maintenance depends on calorie intake, not macronutrient ration.[28]

"The glycemic index (GI) factor is a ranking of foods based on their overall effect on blood sugar levels. The diet based around this research is called the Low GI diet. Low glycemic index foods, such as lentils, provide a slower, more consistent source of glucose to the bloodstream, thereby stimulating less insulin release than high glycemic index foods, such as white bread."[29][30]

The glycemic load is "the mathematical product of the glycemic index and the carbohydrate amount".[31]

In a randomized controlled trial that compared four diets that varied in carbohydrate amount and glycemic index found complicated results:[32]

Diets 2 and 3 lost the most weight and fat mass; however, low density lipoprotein fell in Diet 2 and rose in Diet 3. Thus the authors concluded that the high-carbohydrate, low-glycemic index diet was the most favorable.

A meta-analysis by the Cochrane Collaboration concluded that low glycemic index or low glycemic load diets led to more weight loss and better lipid profiles. However, the Cochrane Collaboration grouped low glycemic index and low glycemic load diets together and did not try to separate the effects of the load versus the index.[33]
