Energy balance

Intermittent energy restriction results in greater weight loss than continuous energy restriction, though statistical equivalence was not met in this trial.

While both diets reduce weight, the intermittent diet (2 days of very low calories) led to slightly more weight loss on average (-6.8 kg vs -5.0 kg) in this study. However, the difference was not statistically proven to be superior, so individual results may vary.

GoodQualifiesMEDIUM confidence
Mean (SEM) weight change was similar between the continuous and intermittent energy restriction groups (–5.0 [0.8] kg vs –6.8 [0.8] kg; P = .25), but the between-group difference did not meet the criteria for equivalence (–1.8 kg; 90% CI, –3.7 to 0.07 kg)

Why this rating

Same trial as N1; high internal validity but inconclusive for superiority due to sample size/power.
