Well, if you intend to lose weight, you do have to check out serving sizes. A half cup of ricotta which is a serving is 170 calories and 10 grams of fat. The container serving size may be smaller but still.......
Calories do count so I would measure olive oil on salads - a Tablespoon has 119 calories and 14 grams of fat. You might consider signing up for
