Have you tried Think Thin bars? 20gm protein, 0 sugar, 8 fat, 230 calories and gluten free...they are wonderful!! I get my protein from 1 per day and milk, eggs, and cheese. Plus chicken and fish. Even after 5 mos I still cannot tolerate pork or beef... Not really a bad thing if you think about it, both are loaded with fat!! You can buy these bars online, Trader Joes, Kroger, Clarks Nutrition and many other stores. My fav is creamy peanut butter. Yum
