Effects of Weight Loss Among Metabolically Healthy Obese Men and Women

چکیده
OBJECTIVE Weight loss among metabolically healthy obese (MHO) individuals may be unnecessary or result in elevated cardio-metabolic risk. We studied the effects of exercise- or diet-induced weight loss on cardio-metabolic risk among MHO and metabolically abnormal obese (MAO) adults. RESEARCH DESIGN AND METHODS Participants were 63 MHO and 43 MAO adults who took part in 3 to 6 months of exercise- or diet-induced weight loss intervention. Changes in anthropometry, adipose tissue distribution, and cardio-metabolic risk factors were assessed. RESULTS Body weight, waist circumference, and total abdominal and visceral adipose tissue were reduced in all subjects (P < 0.05). Improvements in insulin sensitivity were observed in MHO and MAO men and women (P < 0.05), but were greater in the MAO individuals (P < 0.05). Fasting insulin was the only other cardio-metabolic improvement among MHO individuals (P < 0.05). CONCLUSIONS Lifestyle-induced weight loss among MHO subjects is associated with a reduction in total and abdominal obesity and improvement in selected cardio-metabolic risk factors.

متن کاملObesity, High-Molecular-Weight (HMW) Adiponectin, and Metabolic Risk Factors: Prevalence and Gender-Specific Associations in Estonia
BACKGROUND The metabolic consequences of obesity are associated with an imbalance of adipocytokines, e.g. adiponectin. However, some obese subjects remain metabolically healthy and have adiponectin levels similar to normal body weight subjects. Current estimates of the prevalence of obesity in Estonia have relied only on self-report data. OBJECTIVES To estimate the prevalence of obesity in Es...

According to WHO, 53.5–69.5% of adult men and 47.2–61.8% of adult women were classified as overweight in seven European countries. Among adults classified as overweight, 7.7– 26.0% of men and 9.0–21.0% of women were classified as obese (1). BMI is not always related to the degree of insulin resistance, although BMI is an important indicator for diagnosing obesity. Furthermore, a low occurrence ...

BACKGROUND Obesity is a well known risk factor for the development of metabolic abnormalities. However, some obese people are healthy and on the other hand some people with normal weight have adverse metabolic profile, therefore it can be assumed that there is a difference in physical characteristics amongst these people. The aim of this study was to establish whether there are somatotype diffe...
