The Claim
In adults with overweight or obesity, a 4:3 intermittent fasting regimen (three non-consecutive days of 80% energy restriction per week) over 12 months results in greater reductions in binge eating and uncontrolled eating behaviors than daily caloric restriction, despite equivalent total weekly energy deficits.
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 adults with overweight or obesity, following a 4:3 intermittent fasting schedule for 12 months leads to larger decreases in binge eating and uncontrolled eating compared to daily calorie counting, even when both diets result in the same total weekly calorie reduction.
See the scientific wording
In adults with overweight or obesity, a 4:3 intermittent fasting regimen (three non-consecutive days of 80% energy restriction per week) over 12 months leads to greater reductions in binge eating and uncontrolled eating behaviors compared to daily caloric restriction, despite matching total weekly energy deficits, suggesting that dietary flexibility may improve behavioral adherence during weight loss.
When people eat normally on some days and cut calories on others, their hunger hormone levels stay more stable, and the brain's reward system doesn't overreact to food cues. This makes it less likely for them to lose control and eat too much when they are allowed to eat.
What the research says
1 studyPeople who ate normally four days a week and cut calories on three other days ate less out of control and had fewer binge episodes than those who cut calories every day—even though both groups ate the same total amount of calories over the week. The flexible schedule seemed to help people stick to their goals better.
