It is necessary to adequately treat the underlying disease, if any. From here depends seek balance through dietary adjustments. The diet should be adequate to the necessary activity, so a very intensive diet very active people is counterproductive. Must lie to make soft diets and maintained. Once you reach your ideal weight, the ideal is to keep a proper exercise program and diet that mostly does not allow you to regain the lost fat and weight.
The main treatment for obesity is to reduce body fat by eating fewer calories and exercising more. On the beneficial side effect is that exercise increases the strength of the muscles, tendons and ligaments, which helps prevent accidents and injuries from strenuous activity. The diet and exercise programs produce an average weight loss of about 8% of total body mass (excluding the subjects who left the program). Not all dieters are satisfied with these results, but a loss of body mass as small as 5% may represent major health benefits.
Much more difficult to reduce body fat is to try to keep it off which occurred 80 to 90% of those with 10% or more than their body mass through diet gain back all the weight from two to five years. The body has systems that maintain homeostasis at one level, including body weight. Therefore, keeping the weight off generally requires exercising and eating right a permanent part of the lifestyle of people. Some nutrients, such as phenylalanine, are natural appetite suppressants which allows to reset the set level of body weight
In a clinical practice guideline by the American College of physicians, are made the following five recommendations:
People with a BMI greater than 30 should be counseled on diet, exercise and other behavioral factors relevant to be taken over and set a realistic goal for weight loss.
If this goal is not achieved, pharmacotherapy should be offered. Patients need to be informed of the possibility of side effects and lack of information about the safety and efficacy in the long term.
Drug therapy may consist of sibutramine, orlistat, phentermine, diethylpropion, fluoxetine, and bupropion. For more severe cases of obesity, stronger drugs such as amphetamine and methamphetamine may be used selectively. Heredity is not sufficient to recommend sertraline, topiramate or zonisamide.
In patients with a BMI over 40 who fail to reach their goal weight loss (with or without medication) and who develop obesity-related complications, reference may be indicated for bariatric surgery. Patients should be warned of potential complications.
Those requiring bariatric surgery should be referred to reference centers of high volume, because as the evidence suggests surgeons who frequently perform these procedures have fewer complications.
A guide for clinical practice by the U.S. Preventive Services Task Force (USPSTF) concluded that the evidence is insufficient to make a recommend for or against routine advice on behavior to promote a healthy diet in unselected patients in care facilities primary, but this intensive counseling about dietary behavior is recommended in patients with hyperlipidemia and other known risk factors for cardiovascular diseases and chronic diseases. The board may be carried out by primary care clinicians or by referral to other specialists such as nutritionists or dietitians.
Exercise requires energy (calories). Calories are stored in body fat. The arrival body fat reserves to provide energy during prolonged aerobic exercise. The largest muscles in the body are the muscles of the legs and naturally these burn the most calories, which makes walking, running and cycling are among the most effective forms of exercise to reduce body fat.
A meta-analysis of randomized controlled trials conducted by the international Cochrane Collaboration found that "exercise combined with diet results in greater weight loss than diet alone."
In general, the dietary management of obesity is based on reducing food intake. Several dietary approaches have been proposed, some of which were compared by randomized controlled trials:
A study in which 6 months were compared Atkins, Zone diet, Weight Watchers and Ornish diet found the following results:
Four diets generated a modest weight loss, but statistically significant, in the course of 6 months.
Although the Atkins diet generates the greatest weight loss in the first 4 weeks, the weight loss at the end of the study were independent of type of diet followed. "
The highest rate of abandonment of the groups doing Atkins and Ornish diets, suggests that many individuals found these diets are too difficult to follow.
A meta-analysis randomized controlled studies concluded that "compared with usual care, dietary counseling produces modest Xtreem Fat Loss Diet Review weight loss decreases with time."
Low fat vs. low carbohydrate
Many studies have focused on diets that reduce calories via low-carb diets (Atkins, Zone diet) vs. low-fat diet (LEARN diet, Ornish diet). The Nurses' Health Study, an observational cohort study found that low carbohydrate diets based on vegetable sources of fat and protein are associated with less coronary artery disease.
A meta-analysis of randomized controlled by the International Cochrane Collaboration conducted in 2002 concluded that diets that are restricted in fats are better than diets in which calories are restricted, in achieving weight loss over term in overweight or obese.
A more recent meta-analysis that included randomized controlled trials published after the Cochrane review found that "low-carb diets in which energy is not restricted appear to be at least as effective as low-fat diets with restriction of Indian energy and weight loss up to a year. However, potentially favorable changes in triglycerides and HDL cholesterol should be weighed against potential unfavorable changes in the level of LDL cholesterol, when using low carbohydrate diets to induce a weight loss ".
The Women's Health Initiative Randomized Controlled Dietary Modification Trial encontróque a diet with a total of 20% of energy from the energy and increased consumption of vegetables and fruit to at least 5 servings daily and grains to at least 6 servings daily resulted in: there was no reduction in cardiovascular disease, there was a nonsignificant reduction in breast cancer invasiv and no reduction in colorectal cancer.
Recent additional randomized controlled studies have found that: a comparison of the Atkins, Zone diet, Ornish diet, and LEARN diet in premenopausal women found the greatest benefit from the Atkins diet.
The choice of diet for a specific person can be influenced by measuring individual insulin secretion: In young adults "Reducing glycemic load (carbohydrates) can nser especially important to achieve weight loss among individuals with high insulin secretion" . This is consistent with previous studies of diabetic patients in which low-carbohydrate diets were more beneficial.
Low glycemic index
"The glycemic index factor is a ranking of carbohydrate foods based on their overall effect on plasma levels of glucos. Foods with a low glycemic index, such as lentils provide a more constant source of glucose into the bloodstream and slow, thereby stimulating the release of insulin less than foods with high glycemic index, such as white bread. "
The glycemic load is "the product matemáticodel glycemic index and the amount of carbohydrates."
In a randomized controlled trial that compared four diets that varied in the amount of carbohydrates and glycemic index found complicated results:
Diet 1 and 2 were high carbohydrate (55% of total energy consumption)
Diet 1 was high-glycemic index
Diet 2 was low-glycemic index
Diet 3 and 4 were high protein (25% of total energy consumption)
Diet 3 was high-glycemic index
Diet 4 was low-glycemic index
In diets 2 and 3 lost the most weight and fat mass, but low density lipoprotein fell in the diet increased two and three in the diet. Therefore the authors concluded that diets high in carbohydrates, low glycemic index were the most favorable.
A meta-analysis by the Cochrane Collaboration concluded that diets low glycemic or low loads and shows lead to more weight loss and better lipid profile. However, the low glycemic index diets and low load and cynical were grouped together and no attempt was made to separate the effect of the load versus the index.
The most commonly prescribed medication for exercise-resistant obesity / diet is orlistat (Xenical, which reduces intestinal fat session inhibiting pancreatic lipase) and sibutramine (Reductil, Meridia, an anorectic). Weight loss with these drugs is modest and long-term average weight loss with orlistat is 2.9 kg, 4.2 kg with sibutramine and rimonabant 4.7 kg. Orlistat and rimonabant lead to a reduction in the incidence of diabetes, and all drugs have some effect on lipoprotein (different forms of cholesterol).
However, there is little information on long-term complications of obesity such as heart attacks. All drugs have potential side effects and contraindications. Drugs commonly used weight loss for a period (eg three months) and discontinued or changed by other people if the benefit has not been obtained, such as a weight loss of less than 5% of total body weight .
A meta-analysis of randomized controlled studies conducted by international Cochrane Collaboration concluded that in diabetic patients fluoxetine, orlistat and sibutramine could achieve a modest but significant weight loss between 12-57 weeks, with long-term health is not very clear.
Obesity may also influence the choice of drugs for the treatment of diabetes. Metformin may lead to a slight weight reduction (as opposed to sulfonylureas and insulin) and has been shown to reduce cardiovascular disease risk in obese type two diabetics. The thiazolidinediones, can cause slight weight gain, but decrease the "pathologic" abdominal fat and can therefore be used in diabetic patients with central obesity.
Causes and mechanisms
The causes of obesity are multiple and include factors such as genetic inheritance, the behavior of the nervous system, endocrine and metabolic, and the type or style of life that takes.
Increased intake of calories than your body needs.
Low physical activity the body needs.
If ingested more energy than is needed it is stored as fat. If you consume more energy than necessary will use fat for energy. So that obesity is caused by excess energy as a result of alterations in the balance of input / output energy. Following several complications may occur, such as hypertension, diabetes mellitus and coronary heart disease.
Heredity plays an important role, both parents are obese the risk of obesity for children is 10 times higher than normal. This is partly due to trends metabolic fat accumulation, but partly due to cultural food habits and sedentary contribute to repeat the patterns of obesity in families.
Another part of the obese are hormonal or endocrine diseases, and can be solved by a correct diagnosis and specialized treatment.
Most researchers have concluded that the combination of excessive consumption of nutrients and sedentary lifestyle are the main cause of the rapid acceleration of obesity in Western society in the last quarter century.
Despite the widespread availability of nutritional information in schools, offices, Internet and grocery stores, it is clear that the excess consumption remains a substantial problem. For example, confidence in the energy-dense fast food, has tripled between 1977 and 1995, and calorie consumption has quadrupled over the same period.
However, the consumption of food by itself is insufficient to explain the phenomenal rise in obesity levels in the industrialized world in recent years. An increase in sedentary lifestyle also has a significant role to play. More and more research into childhood obesity, for example, I read such things as running at school, with current high levels of this disease.
Questions about lifestyle, less well established, that may influence obesity include mental stress and inadequate sleep.
As with many medical conditions, the caloric imbalance that results in obesity often develops from a combination of genetic and environmental factors. Polymorphisms in various genes controlling appetite, metabolism, and adipokine integration, predispose to obesity, but the condition requires the availability of sufficient calories, and possibly other factors to develop fully. Several genetic conditions that have as a feature of obesity have been identified (such as Prader-Willi syndrome, Bardet-Biedl syndrome, MOMO syndrome, mutations in the leptin and melanocortin receptors), but only single mutations in locus have been found in 5% of obese individuals. IF it is thought that a large proportion of the causative genes are still unidentified, for most obesity is probably the result of interactions between multiple genes where non-genetic factors are also probably important.
A 2007 study identified many common mutations in the FTO gene, the heterozygotes had a risk of obesity increased 30%, while homozygotes had an increased risk of 70%.
At the population level, the thrifty gene hypothesis, which postulates that certain ethnic groups may be more prone to obesity than others and the ability to take advantage of rare periods of abundance and and use this wealth to store energy efficiently, may have been an advantage evolutionary, in times when food was scarce. Individuals with greater adipose reserves were more likely to survive famine. This tendency to store fat is likely maladaptive in a society with a stable food supply.
Obesity is a disease in which the natural energy reserve, stored in fatty tissue of humans and other mammals, is increased to a point where it is associated with certain health conditions or increased mortality. It is characterized by a body mass index or BMI increased (greater than or equal to 30). It is part of the metabolic syndrome. It is a known risk factor for chronic diseases like heart disease, diabetes, hypertension, stroke and some forms of cancer. Evidence suggests that it is a multifactorial disease with genetic, environmental, psychological and others. It is characterized by excessive accumulation of fat in the body, general hypertrophy of adipose tissue.
It is a chronic disease caused by many things and with numerous complications, obesity is characterized by excess fat in the body and occurs when the body mass index in adults is greater than 30 kg / m² according to the WHO (World Health).
Obesity does not distinguish color, age, socioeconomic status, gender or geographic location.
Formerly considered the overweight person as someone who was healthy, but now we know that obesity has multiple negative health consequences. It is now accepted that obesity is a causal factor in other diseases such as cardiovascular diseases, dermatological, gastrointestinal, diabetes, arthritis, etc..
The first step to see if there is obesity or not, is to know the body mass index (BMI), which is obtained by a calculation of height and weight of the individual and he squared.
Although obesity is an individual clinical condition has become a serious public health problem that is growing: we have seen that excessive body weight predisposes to various diseases, particularly cardiovascular diseases, diabetes mellitus type 2, sleep apnea and osteoarthritis .that mostly does not allow you to regain the lost fat and weight.
