Time-restricted eating modestly lowered fat mass during resistance training
A review found small changes in some body composition measures, with no statistically significant differences in body weight or fat-free mass.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Among adults doing resistance training, restricting eating to a daily time window was associated with a small reduction in fat mass. Body mass index and body fat percentage also fell, while differences in body weight and fat-free mass were not statistically significant. The limited evidence leaves the practical importance of these changes uncertain.
The available trials were few, small, and short. Their results do not establish lasting effects, and nonsignificant fat-free mass findings cannot prove that fat-free mass is unchanged.
What researchers found
Fat mass: pooled mean difference
Time-restricted eating versus habitual diet; 95% CI: -1.95 to -0.54 kg. Trial durations were not reported in the abstract.
Different measures, different findings
The clearest reported changes concerned fat mass, body fat percentage, and body mass index. Overall body weight did not differ significantly, illustrating why a body composition result should not be summarized simply as weight loss.
What remains unresolved
The pooled results describe average differences across trials, rather than a guaranteed response for an individual. The authors call for larger studies with consistent protocols to establish whether the changes are clinically meaningful.
