Low-fat means low calorie.
Reducing the amount of fat in food doesn't necessarily mean the food is low in calories. While a product may be lower in fat, the calorie content may be equal to or even higher than that found in the regular product. Eat lower-fat foods in moderation just as you would a full-fat, full-calorie product. The Nutrition Facts panel on the label is the key to finding out the fat and calorie content of foods.
