The Claim

In lean adults, alternate-day fasting and daily energy restriction result in no statistically significant differences in postprandial cardiometabolic health markers or gut hormone responses after 3 weeks of intervention.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

In lean adults, alternate-day fasting and daily calorie restriction produce the same effects on blood sugar, insulin, and gut hormones after meals over a 3-week period.

See the scientific wording

In lean adults, alternate-day fasting and daily energy restriction produce no statistically significant differences in postprandial cardiometabolic health markers or gut hormone responses over 3 weeks, suggesting no fasting-specific metabolic advantages.

Why this might work

When the body gets the same total amount of food every day or skips meals every other day but still eats the same total calories, blood sugar and hormone levels after eating stay about the same because the body adjusts to the total energy it receives, not when it gets it.

  1. Study: A randomized controlled trial to isolate the effects of fasting and energy restriction on weight loss and metabolic health in lean adults

    In healthy, lean people, eating fewer calories every day is just as good for blood sugar and hormone responses after meals as skipping meals every other day — neither method has a clear edge.
