The dietary treatment of obesity

Abstract

In the review atricle, an analysis of sources devoted to the issues of dietary therapy of obesity was carried out. Information was sought through internet resources such as PubMed, MedLine, The Cochrane Databases, Google Scholar, Science Direct, Web of Science, and Scopus. Obesity has reached pandemic proportions worldwide, with more than 1 billion adults overweight (at least 300 million of them are clinically obese) and is a major contributor to the global burden of chronic disease and disability. This is a complex multifactorial disease, in which the accumulated excess fat in the body leads to negative impact on health. The main cause of obesity is a long-term energy imbalance between consumed and expended calories. Lifestyle modification remains the cornerstone of obesity treatment. An individually selected diet is recommended, which allows you to achieve a state of negative energy balance and is focused on quality food for health promotion. Most often, recommended diets for the treatment of obesity use the following energy restrictions based on changes in the composition of macronutrients: a low-fat diet, a low-carbohydrate and high-fat diet, a low-carbohydrate and high-protein diet, a paleo diet (with a high protein content). Intermittent fasting is considered an alternative to calorie-restricted diets. After an initial period on a high-protein diet, a Mediterranean diet may be an attractive option for continued treatment of obesity, provided that it is given in an energy-restricted form. This diet has been shown to be associated with lower levels of inflammatory biomarkers and metabolic markers of cardiovascular diseases risk.The results of many studies indicate successful weight loss with the help of the Mediterranean diet, not only in the short term, but also in the long term. For the majority of obese patients, a purposeful change in lifestyle with adherence to the principles of dietary nutrition and regular physical activity allows for effective weight loss, adequate control of metabolic disorders, reduction of the risk of developing concomitant diseases, and long-term maintenance of body weight achieved in the process of losing weight.
