Changes in body mass during weight loss treatment – a two-year prospective study

Abstract

Introduction: A reduction of 5% to 10% of body mass is related to a significantly lower risk of the occurrence of conditions whose underlying cause is obesity. Aim of the research: The analysis of body mass and body composition changes in overweight and obese patients undergoing weight loss treatment. Material and methods: A total of 129 overweight and obese individuals qualified for the study. All patients were instructed to follow a healthy, balanced diet based on the nutritional standards. The patients were subjected to anthropometric measurements and body composition tests by means of bioimpedance analysis. The analysis included measurements performed 3, 6, 12, and 24 months after the first appointment. One-factor analysis of variance was applied to test the changes of body mass and composition in the following months. Results: The average body mass index of the patients decreased on consequent follow-up appointments from 33.8 ±5.17 kg/m

A Two-Year Follow-Up Cohort Study—Improved Clinical Control over CVD Risk Factors through Weight Loss in Middle-Aged and Older Adults

“…Another important issue in assessing any health benefits gained through the treatment of obesity consists in determining the actual magnitude of weight loss which would offer such benefits. It is widely accepted that 5–10% of weight loss is beneficial to one’s health [ 31 , 32 ]. While these assertions are corroborated by the results of numerous studies, it should also be borne in mind that the association between body weight and individual health outcomes is continuous rather than of a threshold-like character [ 33 ].…”

The Effect of Bariatric Surgery on Weight Loss and Metabolic Changes in Adults with Obesity

“…The existing conservative methods of treatment, including changes in lifestyle, physical activity, restrictive diets, and psychotherapy, are not very effective, resulting in only up to 10% of the desired weight loss [11]. Maintaining body weight is a much more difficult problem, and reduces the effectiveness of these methods of therapy [11][12][13]. The pharmacological methods of treatment of obesity are lipostatins (orlistat); drugs restricting appetite (bupropion, naltrexone); and others, such as lorcaserin, phentermine-topiramate, or liraglutide.…”
