Related questions
Questions this research helps answer.
Fasting and fat-loss answer
Is intermittent fasting better than calorie restriction?
Intermittent fasting can work when the eating window makes a calorie deficit easier to sustain. It is not automatically better than ordinary calorie restriction, especially if the shorter window makes protein harder to hit.
Fasting and muscle answer
Will intermittent fasting cause muscle loss?
Intermittent fasting does not automatically cause muscle loss. The risk shows up when the shorter eating window makes calories, protein, or training quality drop low enough that the body has less reason and less material to keep muscle during a cut.
