Low Carb diet:
Reviews and key studies
This meta-analysis of 23 studies confirms that a low-carb diet significantly improves weight, waist circumference, systolic and diastolic blood pressure, serum triglycerides, HDL, fasting blood glucose, HbA1c, insulin, and C reactive protein levels.

Compared to the historical use of traditional carbohydrate-restrictive therapeutic approaches, the subsequent insulin era, along with medical technological advances, shows an increase in type 2 diabetes and risk of macrovascular and microvascular complications. Only a newer understanding of the importance of postprandial hyperglycemic control is shifting scientific interest toward the health and economic benefits of carbohydrate-restricted diets.

Improvements in diabetes medication, risk factors, cardiac function, and performance range after only three weeks on a low-carb diet: this study from a rehabilitation center for overweight type 2 diabetics compared a moderate low-carb diet (LOGI) with the traditionally recommended low-fat, high-carbohydrate diet, both under a moderate aerobic exercise program in a cross-over design.

In this 2-year follow-up ofdietary pattern, the effects of a) low-fat, limited calories, b) Mediterranean diet, limited calories, c) low-carb, not limited calories, were compared in 322 overweight subjects. The best results for weight loss and lipid profile persisted for the unlimited low-carb diet.
