I said insulin. Not blood sugar levels. If you consume an artificial sweetener your body will release insulin but with no carbohydrate your blood sugar levels will not go up. However if you consume a carbohydrate or a meat protein which has amino acids that are converted to glucose by insulin your blood sugar levels will go up. So eating a steak with water very little insulin response very little to no increase of blood sugar level. Eating a steak with a diet soda you have an insulin response and your blood sugar goes up.
