Pre op diet and only 1 pound!
How many calories are you taking in?
You're on no carbs at all?
Please note: I AM NOT A DOCTOR. If you want medical advice, talk to your doctor. Whatever I post, there is probably some surgeon or other health care provider somewhere that disagrees with me. If you want to know what your surgeon thinks, then ask him or her. Check out my blog.
Are you tracking your protein and water? A lot of us use MyFitnessPal. It breaks down the amount of calories to protein, carbs so it is easier to track. It makes it easier to see what works and what doesn't work for you. Minimum protein and water works for some but some people need more. Start practicing on this so after surgery it will be easier. It's normal to get discouraged at times but don't give up. It is a journey and it takes a while to get where where you need to be.
