The Claim
In adult women with obesity, a 12-week intermittent caloric restriction protocol incorporating weekly refeeds and two 7-day diet breaks results in a nonsignificant trend toward greater preservation of fat-free mass compared to continuous caloric restriction, despite a smaller achieved energy deficit.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among adult women with obesity, a diet plan that includes periodic breaks from calorie restriction preserves slightly more lean body mass than continuous calorie restriction, even when less total energy is reduced.

In adult women with obesity, a 12-week intermittent caloric restriction protocol incorporating weekly refeeds and two 7-day diet breaks results in a nonsignificant trend toward greater preservation of fat-free mass compared to continuous restriction, despite a smaller achieved energy deficit, suggesting potential benefits for lean tissue retention that require confirmation in larger trials.
When eating stops for a few days, the body slows down muscle breakdown and pauses muscle building. When food returns, it quickly rebuilds muscle. Repeating this cycle keeps more muscle intact than if the body is always in a low-food state.
What the research says
1 studyIn women with obesity, taking breaks from dieting (eating normally for a few days) helped them keep a bit more muscle than dieting every day—even though they ate fewer total calories. The difference wasn’t big enough to be certain, but it’s a promising hint.
