Nutrition & Metabolism | Full text | Dietary carbohydrate restriction in type 2 diabetes mellitus and metabolic syndrome: time for a critical appraisal
While low carbohydrate diets may not be appropriate for everyone, choices should be left to individual physicians and patients. Key points that bear on the assessment of benefit vs. risk of carbohydrate restriction are presented below. The discussion focuses on type 2 diabetes but many of the principles will apply to metabolic syndrome and possibly to type 1 as well[6,7].
1. Carbohydrate restriction improves glycemic control, the primary target of nutritional therapy and reduces insulin fluctuations.
2. Carbohydrate-restricted diets are at least as effective for weight loss as low-fat diets.
3. Substitution of fat for carbohydrate is generally beneficial for markers for and incidence of CVD.
4. Carbohydrate restriction improves the features of metabolic syndrome.
5. Beneficial effects of carbohydrate restriction do not require weight loss.
