How to Reduce Calories When Eating Cheese

Diet Information
Calorie Tables showing high and low calories in cheese

Examples
By choosing 1oz fat-free Cheddar cheese instead of 1 oz full-fat Cheddar cheese (three times a week), you can reduce your annual calorie intake by 11,730 calories. (The equivalent of nearly 3.5 pounds in weight.)

Fat and Health
Cheese is one of the fattiest foods you can eat. Even worse, it is rich in saturated-fat, which is linked to heart disease. (e.g. 66% of the fat in Cheddar cheese is saturated.) So, for the sake of your health, choose lower fat cheese, or (ideally) "fat-free" cheese. Fat-free cheese contains less than 0.5% fat.

Remember
Weight loss and dieting doesn't mean eating less - just different.
