i think he's gonna start wiggin' out cause his blood sugar is gonna go down...lol Low carb diets work, but are not very healthy. Your CNS runs off of glucose. Your body will go into keto w/o the carbs and supply the CNS w/ fuel, but eventually its gonna be detrimental to your health. Best thing to do is cut out carbs late at night
Without some carbohydrates to maintain blood sugar levels and fuel the system, ketone bodies - fatty substances generated from the breakdown of stored fats or triglycerides - are soon formed in the blood. Ketone bodies mask your appetite even though your brain demands glucose. The result is ketosis: headaches, light-headedness, and mental fatigue. Eventually, [on a low fat diet] your body will begin to convert protein from your muscles into blood sugar. You lose weight, but it is from muscle mass, not from fat. (Pocket Books, 1997)
