The Claim
Intermittent fasting regimens including alternate-day fasting, 5:2 fasting, and time-restricted eating produce comparable weight loss outcomes with no statistically significant differences between them, as demonstrated in a meta-analysis of 24 randomized controlled trials involving 1,768 adults.
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, intermittent fasting methods such as alternate-day fasting, 5:2 fasting, and time-restricted eating result in the same amount of weight loss, with no meaningful difference between them.
See the scientific wording
Intermittent fasting regimens (ADF, 5:2, TRE) result in comparable weight loss to each other, with no statistically significant differences observed between them in a meta-analysis of 24 randomized trials involving 1768 adults.
When a person eats, the body stores excess energy as fat. When they stop eating, the body switches to burning stored fat for energy. This back-and-forth between storing and burning fat happens the same way no matter when or how often the person eats, so all types of intermittent fasting lead to similar amounts of fat loss.
What the research says
1 studyThe study found that alternate day fasting, the 5:2 diet, and time-restricted eating all led to about the same amount of weight loss — none was clearly better than the others.
