Pre-Carbs in the ULC meals should be non-existent.For the ULC meals stick to 1:1 in grams (fats and proteins). I would opt for eating about half you lean body weight in those meals. So if your lean weight is about 160lbs then eat about 80g of protein matched with fat. It's a good starting point but do what works best for you. Now you see how with a certain body weight has a certain number of carbs, that's the max limit you can take in. Work with that number and dial it in. Going overboard is best and then lowering it based on how you look and feel the next day.
