Well, you're eating both fat and protein, so your body will look for dietary sources first. So, with sufficient protein in your diet, you need not worry. Protein can be converted to glucose, too. || || This is somewhat similar to my previous post, sorry, but I had || something else in mind. || || When I go to the gym while in Ketosis, I tend to workout harder || knowing I am burning fat for energy in every move I make. || || Is it the case? || Probably not. You're burning ketones and whatever protein that got converted to glucose (primarily used by the brain). Some lifting movements require different energy systems that fat. But the more energy you burn, the greater the calorie deficit you can create, and the better you lose fat. Don't worry about it too much. Just get sufficient protein and maintain a calorie deficit. || Thanks, || || J.
