XP Nutrition Keto – These ketones are then used to fuel the body in the absence of glucose. In the beginning of a keto diet, especially with high levels of insulin resistance, some anecdotal reports find “too much” protein can slow down the progression to ketosis and blood sugar control. This is likely less of a concern as insulin resistance improves and should not dissuade people from eating protein. One trial showed that diets providing 20 grams and 50 grams of carbs equally helped healthy volunteers maintain ketosis. However, we don’t know if the same is true for people with obesity, insulin resistance or diabetes.
