Give up chocolate? Are you nuts? lol
Hersey's has great chocolate sticks that are 60 calories/4 fat grams. I always make my lunch so that I have enough room to have 1 stick as my "treat" at the end of the meal.
I buy a big bag of "snack" size chocolate candies at Costco, split it up into 4 1 gallon freezer bags, one for each person. That way everyone is responsible for themselves and how much they eat at one time. I'm good and try to have 1 - 2 a day. Serving sizes on this size candy are usually 2 - 4 of the candies.
Skinny Cow has a great line of ice cream treats. Many of them are under 150 calories/3 fat grams. They have a great dipped one that is only 60 calories.
So, I guess I don't have "forbidden" foods, just use alternatives so I can enjoy what I want. Anything that is high calorie/fat is always negotiable because I can always choose to work off those calories with exercise. When I look at things like cake or cookies I think about how much time it will take to work off whatever calories are in it. :) Keeps me from eating too many of those.
