Key result
Exercise interventions reduce weight and visceral and subcutaneous fat in overweight and obese adults.
Why the study?
Overweight and obese adults seek effective exercise interventions to reduce accumulated fat, but the effectiveness of these interventions varies across studies.
Do exercise interventions reduce weight and accumulation of subcutaneous, visceral, and ectopic fat in overweight and obese adults?
Meta-Analysis
Do exercise interventions reduce weight and accumulation of subcutaneous, visceral, and ectopic fat in overweight and obese adults?
Moderate to vigorous exercise interventions over approximately 22 weeks effectively reduce weight, subcutaneous fat, and visceral fat in overweight and obese adults.
Supports exercise prescription in overweight/obese adults to reduce adiposity; confirms pooled benefits on visceral fat across 21 studies.
Background: Overweight and obese adults seek effective exercise interventions to reduce accumulated fat, but the effectiveness of these interventions vary across studies. The purpose of this meta-analysis was to investigate the effectiveness of exercise interventions in overweight and obese adults based on measurement of accumulated fat distributions. (2) Methods: Databases were used to select eligible studies for this meta-analysis. Randomized controlled trials with a control and experimental group were included. Degrees of effectiveness of exercise interventions were computed to assess the benefits on reducing weight and subcutaneous, visceral, and ectopic fat accumulation. (3) Results: A total of twenty-one studies were included in this meta-analysis. Participation in exercise interventions showed beneficial effects in reducing weight and subcutaneous and visceral fat. The effectiveness of exercise interventions on ectopic fat accumulation could not be assessed due to the limited number of studies measuring ectopic fat. Additionally, effectiveness of exercise interventions that depended on measurements of accumulated fat varied. The average exercise intervention for overweight and obese individuals was moderate to vigorous intensity, 4 times per week, 50 minutes per session, and 22 weeks duration. (4) Conclusions: Participating in exercise interventions has favorable effects on reducing weight and accumulation of subcutaneous and visceral fat.

Junga Lee (2020) conducted a meta-analysis in Overweight and obesity. Exercise interventions vs. Control group was evaluated on Weight and subcutaneous, visceral, and ectopic fat accumulation. In a meta-analysis of 21 studies, exercise interventions (average 22 weeks) favorably reduced weight and accumulation of subcutaneous and visceral fat in overweight and obese adults.
