You need to find out the fat amount that you can have following your surgery. Talk to your doctor or dietitian for the specific amount. Take this amount and divide it into 3 meals and 1-2 snacks. Now you know how much to include with each meal and you will be able to tell if a recipe works. Most folks do well if they avoid high fat meats, fried foods, foods in cream sauces, cheese sauces, gravies, pastries/doughnuts/biscuits, etc. The rest of the foods work: lean meats, low fat dairy, fruits, veggies, whole grains.
You will then probably find that you can transition back to your Sparkpeople ranges for calories, fat, carbs and protein as you heal.
Most folks can tolerate low fat dairy. Skim and 1% milk, lowfat cheese, lowfat yogurt.
hope this helps
