A meta-analysis of six randomized controlled trials was done and it is found that there was no difference between the major types dietary calorie (low, Low - carbohydrate and low fat) with 2.4 kg of body weight in all studies. At two years, all types of energy-restricted diets lead to weight loss are equal.

Low-fat diet
This types of Diet is a Diets with low in fat include a reduction in the proportion of fat in the diet. The caloric intake is reduced, but not intentionally. Diets of this type include the NCEP Step I and II. Meta-analysis of 16 trials lasting 2-12 months conclusion "that the diet low in fat leads to weight loss of 3.2 kilograms (7.1 pounds) of food as normal

The low-carb diets Low-carb Atkins diet is a diet with low carbohydrate and energy . They are very popular in the press, but not recommended by the American Heart Association. Review of 107 studies have found that low-carbohydrate diets cause weight loss, except when there was limited calories. It was found adverse effects of a diet low in carbohydrates

Low-calorie diet This type of low calorie diets usually designed to produce energy shortage 500-1000 calories per day, which can lead to 0.5 to one kilogram (1.1 pound) weight loss per week. They include the DASH diet and Weight Watchers, among others. National Institutes of Health, examined 34 randomized controlled trials to determine the effectiveness of diets low in calories. They found that these diets reduce total body weight of 8% over 3-12 months Most diets low in calories Low calorie diets Very provide 200-800 kcal / day, the preservation of protein and caloric restriction on lipids and carbohydrates. They expose the body to hunger and produce weight loss weekly average 1.5-2.5 kg (3.3-5.5 pounds). These schemes are not recommended for general use because they are associated with side effects such as loss of muscle mass, increased risk of gout, and electrolyte imbalance. People have tried these systems must monitor closely the doctor to prevent complications. Fat loss compared to a loss of muscle tissue Weight loss usually leads to loss of fat, water and muscle. People with overweight or obesity, usually to reduce the proportion of fat in the body. In addition, as muscle tissue is denser than fat, the results of fat loss increased loss of body parts over the loss of muscle tissue. Even reducing 10% of body fat may have a strong influence on body shape. To determine which part of the weight loss is attributable to the reduction of adipose tissue, various methods of measuring body fat percentage have been developed.

Pharmaceutical validation

The loss of muscle tissue during weight loss may be limited by lifting weights regularly (or doing push-ups and other strength-oriented measures gymnastics) and maintaining sufficient protein intake. People on low carbohydrate diet, and those that are particularly intense exercise can increase their protein intake. According to the National Academy of Sciences, dietary intake for Reg protein, 0.8 grams per kilogram of body weight for adults. "

Pharmaceutical process validation

Excessive protein can lead to liver and kidneys and may be a risk factor for heart disease. There is no conclusive evidence that moderate diet with high protein content in healthy people is dangerous, it has been shown that these diets are dangerous for people who already have kidney and liver.
Obtaining Energy from Food Energy intake from food is limited to the digestive efficiency and effectiveness of their use. The efficiency of digestion is largely dependent on the type of food consumed, and efficiency of use depends on individual factors including body weight and hormones.
Consequences of chewing, especially among the elderly, have been shown to affect the consumption of micro nutrients. However, there was no significant effect on the consumption of macro nutrients, like sugar, fats and proteins Good food
Food provides nutrients from six broad categories: proteins, fats, carbohydrates, vitamins, minerals, food and water. Carbohydrates are metabolized to generate energy. Protein provides amino acids necessary for the construction of cells, especially for the construction of muscle cells. Essential fatty acids are necessary for the brain and the construction of cellular membranes. Vitamins and trace minerals help maintain proper electrolyte balance and are necessary for many metabolic processes. Dietary fiber other elements that affect health, even if it is not actually absorbed by the body.
Hence any type of diet that does not meet the minimum nutritional requirements can threaten general health (physical and special). Quality If a person is not well enough to be active, weight loss and good of life is unlikely. National Academy of Sciences and the World Health issued guidelines for the feeding of all essential nutrients.
Sometimes food would ingest excessive amounts of vitamins and mineral supplements. Although usually harmless, some nutrients are dangerous. The men (and women who are not monthly) should be wary of iron poisoning. Retinol (vitamin oil-soluble A) toxic in high doses. Typically, most people can get their nutrients from food. In any event, a multivitamin taken once a day would be enough for most people.

For diets that manipulate the proportion of macronutrients (low in fat, carbohydrates, etc.) were not considered more effective than a regime that supports a typical mixture of products with smaller portions and perhaps some substitutions (eg, low - low-fat milk, salad or less). Extreme regimes May, in some cases can lead to malnutrition.
As the body gets rid of fat All body processes require energy to function properly. When the body spends more energy than it takes in (eg, in the year), the body's cells depend on domestic sources of energy are stored as complex carbohydrates and fats energy. The first source the body turns to glycogen, is (by glycogenolysis). Complex carbohydrate glycogen, where 65% of them are stored in skeletal muscle, and the rest in the liver (for a total of approximately 2000 kcal per body). It is created from swallowing too much makropitatelnyh, carbohydrates mostly. When these sources are nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat reserves for energy production. In this process the fat from adipose tissue and fat cells are broken down into glycerol and fatty acids, which can be used for energy production. The main product of metabolism of carbon dioxide and water, carbon dioxide is released through the respiratory system.

Fat is also allocated to the sebaceous glands (the skin). Psychological aspects of diet weight loss Diets affect the energy in "component of energy balance by limiting or changing the distribution of food. Methods that affect the appetite can limit energy consumption, influence the desire to overeat. The cognitive-behavioral therapy is effective in producing long term weight loss. Judith S. Beck was one of the most prominent practitioners and writers to put this technique for a popular audience.
Low energy consumption of foods rich in fiber, such as non-starchy vegetables, is effective in achieving saturation (the feeling of "fullness"). Exercise is also helpful in the fight brilliantly as drinking water and sleep. Using drugs to control appetite is also common. Stimulants are often seen as a way to eradicate hunger in people who are dieting. Ephedrine (by facilitating the release of adrenaline and noradrenaline) stimulates the alpha (1)-subtype of adrenergic receptors, which are known to act as an anorexic. L-phenylalanine, an amino acid found in protein powders whey can also suppress appetite by increasing the hormone cholecystokinin (CCK) which sends a signal of satiety to the brain.
Group weight loss
There are both commercial and non-weight loss without profit to help people in their efforts to reduce weight. The example is the first Weight Watchers, examples of the latter include Overeaters Anonymous, and many nongovernmental organizations, support groups, trade maintenance of local churches, hospitals, and associates.
These organizations customs and practices vary considerably. Some groups are modeled on the twelve step program, and others completely unofficial. Some groups of certain prepared foods or special menus, while other trains diet to healthy choices in the menu of restaurants and a grocery-shopping and cooking.
Most groups leverage the power of group meetings to provide advice, counseling, problem solving, and useful information Food diary A July 2008 study published in the American Journal of Preventive Medicine found diets that keep a daily journal to food (food or magazines), what they eat lose twice as much weight as those who don ' have not. The researchers concluded: "It seems that the simple act of what you eat encourages people to consume fewer calories." Diet Journal software and Web sites have become popular to help people keep track of calories, Calorie expenditure targets weight loss and nutritional balance.
Medications
Some medication may be appointed to assist in weight loss. The last recipe drug weight loss is published Acomplia (generic name Rimonabant) Sanofi Aventis. Used to treat obesity in people with a BMI (Body Mass Index) of 30 or above, and for smoking cessation therapy, Acomplia has yet to be approved by the FDA for use in the United States. Other weight loss drugs such as amphetamines, are dangerous, and it is currently prohibited for weight loss random. Some additives, including those containing vitamins and minerals, can not be effective for weight loss.
Diuretics
Diuretics cause weight loss through the provision of water. These pharmaceuticals or drugs or herbs will reduce the total weight of the body, but have no effect on body fat face. Diuretics can thicken the blood, causing spasms, kidney and liver. In a report the death of Jacqueline Henson has been associated with a tumor in his brain, which has been linked to excessive consumption of water in a short amount of time it was on a special diet of water.
Stimulants
Stimulants drugs or pharmaceuticals such as ephedrine, green tea, caffeine or synephrine work to increase the basal metabolic rate. Dangers of fasting. Prolonged fasting can be dangerous because of the risk of malnutrition and will be under the supervision of a physician. Prolonged fasting or very low calorie diets lower blood glucose, the preferred source of energy in the brain causes the body to deplete their glycogen stores. When the glycogen depleted, the body begins to feed the brain using ketones and the metabolism of body proteins (including but not limited to, skeletal muscle), which will be used for the synthesis of sugar used as energy for other body parts. Most experts believe that prolonged fasting can lead to muscle atrophy, although some dispute this. The use of short-term fasting, or different forms of periodic fasting was used as a form of regime to circumvent this problem.
Overdose Diet, especially extreme reduction of food intake and rapid weight loss, may have the following side effects: Prolonged hunger Depression Decreased sexual desire Tired Irritability Fainting Sinus problems (especially after nasal discharge) Muscular Atrophy Rash Acidosis Bloodshot eyes Diseases of the gallbladder Exemptions Malnutrition, which can lead to death Further increase in weight
Low-carb versus low-fat Many studies have focused on diets that reduce calories via a low carbohydrate (Atkins diet, Scarsdale diet, Zone diet) against a diet low in fat (supplementary feeding, the Ornish diet). Nurses' Health Study, an observational cohort study showed that diet low in carbohydrates from plant sources of fats and proteins associated with decreased coronary heart disease.
Meta-analysis of randomized controlled trials on the international Cochrane Collaboration in 2002 concluded that reduced fat diets no better than calorie restriction diets in achieving long term weight loss, people overweight or obese. A meta-analysis that included more recent randomized controlled trials published after the Cochrane review showed that "low-carb, non-energy restricted diets seem at least as effective as low-fat, energy restricted diets lead to weight loss for up to 1 year. However, potential favorable changes in triglycerides and a high value of cholesterol in lipoprotein density must be weighed against potential unfavorable changes in low levels of cholesterol, high density lipoprotein, low value, when-carb diets cause weight loss are taken into account.
Women's Health Initiative Randomized Controlled Dietary Change Court found that dietary consumption of fats and 20% of energy and increasing fruits and vegetables at least 5 servings daily and grains to at least 6 servings per day, resulting in: without reducing cardiovascular A slight reduction in invasive breast cancer No reduction in colorectal cancer More recent randomized controlled trials have demonstrated that:
Comparison of Atkins, Zone Diet, Ornish diet and a diet study in premenopausal women found the greatest benefit of the Atkins diet. Choose a plan for an individual can influence the measurement of human insulin secretion: Among young adults "Reducing glycemic [carbohydrate] load may be especially important for achieving weight gain in people with insulin secretion.
This is consistent with previous studies of patients with diabetes, in which diets low in carbohydrates have been more useful. American Diabetes Association has published the first recommendation (in January 2008 Clinical Practice Recommendations) for low carbohydrate diets for weight loss for people with or at risk of type 2 diabetes
Low glycemic index "The glycemic index (GI) factor for ranking foods according to their overall impact on levels of blood sugar. Power is based on this study is called a low GI diet. Foods with low glycemic index such as lentils, provide a slower, more stable source of glucose in the blood, thereby stimulating less insulin release that foods of high glycemic index such as white bread. "
The glycemic index is an index of "mathematical product of blood glucose levels and amounts of carbohydrates. In randomized controlled trials have compared four different diets in the carbohydrate and glycemic index found complicated results: Plan 1 and 2 were high in carbohydrates (55% of the total energy consumption) Plan 1 has a high glycemic index Diet 2 has a low glycemic index -- Plan 3 and 4 with high protein content (25% of the total energy consumption) Plan 3 has a high glycemic index Diet 4 was a low glycemic index -- Plan 2 and 3 have lost the most weight and body fat, however, the low density lipoprotein decreased in 2 food and feed has increased by 3. Thus, the authors concluded that high-carbohydrate low-glycemic diet was the most favorable.
Meta-analysis of the Cochrane Collaboration concluded that low glycemic index or low glycemic index diet resulted in significant weight loss and improved lipid profile. However, the Cochrane Collaboration are grouped low glycemic index diets and low glycemic load together and did not attempt to disentangle the effect of the load relative to the index.
