The Claim
In obese adults with type 2 diabetes on metformin, a 12-hour overnight fasting regimen combined with calorie restriction causes a 9.39% reduction in body fat mass after 12 weeks, which is significantly greater than the 5.32% reduction observed with calorie restriction alone, demonstrating enhanced fat loss independent of total caloric intake.
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 obese adults with type 2 diabetes taking metformin, fasting for 12 hours overnight along with reduced calorie intake leads to a 9.39% loss of body fat after 12 weeks, which is greater than the 5.32% loss from calorie restriction alone, showing that the fasting period contributes additional fat loss beyond just eating fewer calories.

When food is only eaten during a 12-hour window, the body runs out of sugar from meals and starts burning fat for energy. Insulin levels stay low for longer, which tells fat cells to release stored fat into the blood. The liver then turns that fat into fuel, leading to more fat loss than just eating fewer calories.
What the research says
1 studyIn people with type 2 diabetes who are overweight, eating only during a 12-hour window each day while eating fewer calories helped them lose nearly twice as much body fat as just eating fewer calories alone — even though both groups ate the same total amount of food.
