Myth 2: Eating Fat Will Not Affect Blood Sugar

Fat does not directly roite roise couse because it is nott a carbohydrate. However, this fact has led to a dangerous oversimplification: thee belief that high- fat meals are neutral for blood sugar control. In reality, dietary fat experts a powerful indirect effect on glucose metatimism thugh seal mechanisms.

First, fat slows gasric emptying, which delays thee absorption of carhydrates consumed in thee same meal. This can shift thee glucose peak from one hour after eating to three or four hours later - a phenonoun often called thee pizza effect because of thee delayed spikes seen after highter-fat, high- carb meals like pizza.
