“In many weight loss diets, people usually (give up) because of hunger pangs,” said Dr Lim, at an event to share the findings of a study on the diet at NUH on Wednesday.
With a healthy keto diet, however, once a person reaches ketosis in typically two to three days, the gut will naturally produce higher levels of glucagon-like peptide-1 (GLP-1), a hormone that helps to increase satiety and reduce cravings, she added.
It is unlike traditional keto diets, where one may eat a high amount of saturated fats and red meats in place of carbohydrates. Such diets have been linked to increased levels of low-density lipoproteins (LDL), or bad cholesterol.
