A report by the French Agency for Food Safety warning about the dangers of weight loss plans covered.
The French Agency for Food Safety (ANSES) issued a report in 2010 showing the ravages biological, psychological, social and economic plans to target weight loss. The analysis of several dieting “indicates that they can induce nutritional imbalances and mismatches contributions (deficiency and excess), including vitamins and minerals” (p. 83). In the medium term, these diets can disrupt profoundly the functioning bone, muscular, metabolic, cardiovascular, hormonal and psychological. These changes stimulate entered a vicious circle of recovery more severe end of each diet weight. In this context, the authors consider the regular adapted as an essential criterion for stabilization of body weight physical activity practice.
The Report Rationale
Overweight affects 32% of French over 18 years, 14.5% for obesity. But now everyone wants to lose weight because the thinness has become a key criteria for beauty. So a race to weight loss begins, especially with the approach of summer. Dieting (Dukan, Cohen …) are they an effective medium-term solution and safe for health?
Diets are they really effective and safe for health?
Dieting without medical supervision is harmful to health?
The French Agency for Food Safety (ANSES) asked experts meet to analyze the effectiveness of restrictive diets (diet, low fat diet, low calorie diet, high protein diet, low carbohydrate diet) to using data from the scientific and medical literature. Particular attention was paid to those at risk (children, elderly, athletes). A final record of 158 pages was published in November 2010 by the French Agency for Food Safety (ANSES). It is available on the website of the French Agency for Food Safety (ANSES).
The report by the French Agency for Food Safety (ANSES) details the devastation caused by the plans referred to weight loss (Dukan, Cohen …). No efficacy could not be identified so weight regain after a year is important (80%) and so the lack of long-term clinical study is striking. A diet does not seem better than another. The analysis shows that dieting can lead to nutritional imbalances and mismatches contributions (excess and deficiency) such as vitamins and minerals. In the medium term, these diets can disrupt profoundly the bone operation (eg demineralization by lack of calcium), muscular, metabolic, cardiovascular (including abnormal heart rhythm), hormonal and psychological (loss of satiety, addiction, disorders of the self-esteem, anxiety). These physiological and psychological disorders stimulate entered a vicious circle of recovery even more severe end of each diet weight. Risks are superimposed in specific populations, children (growth disturbances), the elderly (risk of malnutrition), sports (hormonal disorders). The report recommends consulting a doctor if body mass index greater than 30 They also recommend regular physical activity practice to stabilize body weight.
With the current knowledge, no diet seems more effective than another. Consulting a doctor before a scheme to a significant weight loss is recommended by the HANDLE to the risks involved.
What it means in general
Except in cases of major weight problem (Mass Index greater than 30 Body), the French Agency for Food Safety recommends starting a diet referred to weight loss. These diets are not recommended for more people without weight problems for people at risk (children, the elderly, athletes). These diets increase the risk of bone fractures and heart disease. They deconstruct the appetite to forget hunger and the pleasure of eating. Eating becomes guilt. After one year, 80% of those with a restrictive diet resumed at least their initial weight.
The message for Healthcare Professionals
A restrictive diet is psychologically untenable (eating disorders) and sociologically (opulence food, modern lifestyle …). Physiological disorders caused by dieting (low fat, low calorie, high protein, low carbohydrate) may irreversibly alter health. At the end of a regime, the person begins to eat and automatically resumes weight. The potential to grow even more than before becomes major (“yoyo” effect). Medical supervision is necessary for any weight problem. Regular physical activity is essential to stabilize the body weight.
The message for Researchers
Contrary to what can be said, restrictive diets (low fat, low calorie, high protein, low carbohydrate) are rarely the subject of serious research, especially long-term (2 to 10 years). The report by the French Agency for Food Safety (ANSES) encourages researchers to engage on this issue and that is going to debate.
The message for Policymakers
Dieting (low fat, low calorie, high protein, low carbohydrate) is a health hazard and ineffective after one year (80% weight recovery). Consider how to roll back the cult of thinness in a world of opulence and encourage intervention research to test the effectiveness of restrictive medium-term plans seem indispensable.
