Long-term practice of a ketogenic diet for obese populations shows health benefits, yields no harmful side effects
A ketogenic diet is high in polyunsaturated fatty acids, consists of adequate protein, and is low in carbohydrates. Previous studies have shown the short-term effects of this diet in weight loss among obese populations; a recent study, however, was interested in determining the long-term effects of the diet on physical and biochemical factors.
More than 80 obese patients participated in the study, which put them on a 24-week ketogenic diet (consisting of 30 grams of carbohydrates, 1 g/kg body weight protein, 20% saturated fat, and 80% polyunsaturated and monounsaturated fat.)
After 24 weeks participants experienced a significant decrease in weight, body mass index, triglyceride levels, and blood glucose levels and a significant increase in HDL cholesterol levels.
The researchers conclude that a long-term ketogenic diet has significant health benefits and did not produce any significant side effects in the patients.
