The Claim
Among middle-aged, obese adults with type 2 diabetes on metformin, a 12-hour overnight fasting regimen combined with calorie restriction results in a median HbA1c reduction of 0.50 percentage points after 12 weeks, which is significantly greater than the 0.20 percentage point reduction observed with calorie restriction alone.
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.
In middle-aged obese adults with type 2 diabetes taking metformin, combining a 12-hour overnight fast with calorie restriction lowers HbA1c by 0.50 percentage points after 12 weeks, compared to a 0.20 percentage point reduction with calorie restriction alone.

Among middle-aged, obese adults with type 2 diabetes on metformin, a 12-hour overnight fasting regimen combined with calorie restriction leads to a median HbA1c reduction of 0.50 percentage points after 12 weeks, significantly greater than the 0.20 percentage point reduction observed with calorie restriction alone, indicating improved glycemic control.
When food is not eaten for 12 hours each night, the body uses up stored sugar, which makes cells more responsive to insulin. This lets the liver stop releasing too much sugar into the blood, lowering blood sugar levels over time.
What the research says
1 studyIn a study, people with type 2 diabetes who ate only during a 12-hour window each day and cut calories lost more blood sugar (HbA1c) than those who just cut calories. The fasting group’s HbA1c dropped twice as much, showing this approach works better.
