The Claim
Intermittent fasting and caloric restriction cause weight loss in overweight and obese adults, producing clinically meaningful reductions in body weight and fat mass over periods ranging from 1.25 to 24 months, as demonstrated in multiple randomized controlled trials involving diverse adult populations including individuals with prediabetes, non-alcoholic fatty liver disease, and postmenopausal women.
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.
Both skipping meals now and then (intermittent fasting) and eating fewer calories can help overweight adults lose weight and body fat over several months, according to several studies.
See the scientific wording
Intermittent fasting and caloric restriction cause weight loss in overweight and obese adults, with both approaches producing clinically meaningful reductions in body weight and fat mass over periods ranging from 1.25 to 24 months, as demonstrated across multiple randomized controlled trials involving diverse adult populations including those with prediabetes, non-alcoholic fatty liver disease, and postmenopausal women.
What the research says
1 studyThe review includes 30 RCTs, many of which directly measured weight changes in intervention vs control groups. Consistent directional effects across studies support a causal interpretation of weight loss due to these dietary interventions.
