@jeanne5009 I have mentioned this many times before on this forum so those who have been with it for a while might say "there she goes again", but I don't know how I would have done it without tracking everything I put in my mouth by using myfitnesspal.com. Initially it is somewhat cumbersome but then it gets easier. I also used a fitness tracker to make sure I really was getting enough exercise.
Without those two things I know I would not have been successful. The one other thing I did was to make an excel sheet and track my weight daily. My scale shows an estimate of your BMI and fluid too so I kept track of all of that. It was reassuring if my weight went up to see that I was retaining fluid, plus it let me know that I must have overdone sodium.
Good luck to you. I firmly believe that my excellent recovery had a lot to do with what I did beforehand.
