A new study analyzed data from three clinical trials and found that an individual’s fasting blood glucose and insulin levels determined the type of diet they would best lose weight on possibly suggesting that one diet does not fit all, and a personalized dietary approach may be more suitable.

People with normal blood sugar levels lost most weight on a low-fat high/carbohydrate diet, whereas pre-diabetic individuals lost more weight on a diet with more focus on the quality of the carbohydrate content (i.e. lower glycemic index and more fiber). For the overweight and obese diabetics, a low carbohydrate/high fat and protein in the diet was most beneficial for weight control and glycemic status.
