The Study
A secondary analysis of indices of hepatic and beta cell function following 12 weeks of carbohydrate and energy restriction vs. free-living control in adults with type 2 diabetes
This study is like a test where people were randomly put into two groups to see if a special diet helps with diabetes. It shows the diet probably helped with some liver and blood sugar problems, but we can't be 100% sure because the study was small and we don't know if the doctors knew which diet each person was on.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Eating very few carbs and calories for 12 weeks helped people with diabetes and obesity have less fat in their liver, better blood sugar control, and improved liver health, but did not help their pancreas work better.
