Wow.. that looks like a huge pain in the butt. If it would be unhealthy for you to lose weight, it looks like you can still have low-fat cheese and lean meats, eggs. Check on peanut butter – it’s high calorie, and has good fats in it. It looks like you can have whole grain bread, that plus some low-fat cheese would be good. Can you have pasta noodles? those are fairly high calorie.

While I don’t see anything on that list that says ‘no peanut butter’ – it is ‘fatty’. so I don’t know. You’d have to ask your doctor about making sure you have enough to eat – lean meats don’t have a lot of calories, and I imagine you wouldn’t want to eat tons of it. Figure out what you do eat in a day, and count the calories up. If you don’t have enough, – 1200 min, for a woman, 1500 min, for a man, more if you aren’t on a diet – closer to the 1800-2200 range, find out if maybe you can have soups with veggies and beans and rice maybe? The site suggests ‘brown rice’, so maybe a veggie and meat stir-fry with soy sauce would work.

It shouldn’t be too hard to make sure you have enough calories not to lose weight, but you may find yourself needing to snack often.

Good luck.
