The Study
Intermittent fasting for glycemic control in patients with type 2 diabetes: a meta-analysis of randomized controlled trials.
This study looked at lots of small experiments where people with diabetes tried fasting and compared them to others who didn’t. It found that fasting often helped lower blood sugar and weight, but it didn’t prove fasting caused those changes—other things could’ve helped too.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
