Carbohydrate restriction improves the features of Metabolic Syndrome.
"Five symptoms common to most definitions of Metabolic Syndrome are those that are reliably improved by carbohydrate restriction. Carbohydrate restriction is one strategy for weight loss but, in addition, improves glycemic control, insulin levels, TAG and HDL levels even in the absence of weight loss."
They suggest that Metabolic Syndrome, is a bodily response to excess carbohydrate.
The insulin resistance syndrome: definition and dietary approaches to treatment
"Since being overweight/obese and sedentary decreases insulin sensitivity, it is not surprising that the prevalence of the manifestations of the insulin resistance syndrome is increasing at a rapid rate. From a dietary standpoint, there are two approaches to attenuating the manifestations of the insulin resistance syndrome:" (a) weight loss to enhance insulin sensitivity; and (b) changes in carbohydrate/protein/fat content of diets.
Weight and Metabolic Outcomes After 2 Years on a Low-Carbohydrate Versus Low-Fat Diet
"Successful weight loss can be achieved with either a low-fat or low-carbohydrate diet when coupled with behavioral treatment. A low-carbohydrate diet is associated with favorable changes in cardiovascular disease risk factors at 2 years."
Long-term effects of a ketogenic diet in obese patients
"The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a relatively longer period of time did not produce any significant side effects in the patients. Therefore, the present study confirms that it is safe to use a ketogenic diet for a longer period of time than previously demonstrated.
Carbohydrate restriction as the default treatment for type 2 diabetes and metabolic syndrome.
"Substitution of fat for carbohydrate generally improves cardiovascular risk factors. Removing the barrier of concern about dietary fat makes carbohydrate restriction a reasonable, if not the preferred method for treating type 2 diabetes and metabolic syndrome. We emphasize the ability of low-carbohydrate diets to improve glycemic control, hemoglobin A1C and to reduce medication. We review evidence that such diets are effective even in the absence of weight loss."
