Hello @mopeede and welcome to Mayo Connect. You ask a good question about food when you need to watch sugar and fat intake but also need to keep up your weight. While we wait for other members to respond to your question, I'm wondering how frequently you eat. Small, frequent meals tend to work better after any digestive tract surgery. Do you try to eat three large meals a day or smaller frequent meals?

Also, a registered dietician is a good resource to help with meal planning after surgery and problems with weight loss. You might ask your doctor for a referral to a registered dietician. They can be quite helpful in developing food plans.

Have you found any foods that are a particular problem to you?
