answer:Sugar and fat are both sources of calories. Whatever calories you don’t burn every day become stored as fat. You’d have to look up nutrition facts for the regular versus ‘fat-free’ capuccino. (And there are many websites out there that list nutrition facts for packaged foods and drinks, or for portions of recipes. Just look around on Google.) Sometimes ‘fat-free’ is just a marketing ploy, and the company has to put in more sugar or something else equally caloric in order to keep the product tasting good. But yes, cutting either sugar or fat from your daily drink would cut the total number of calories you intake. Cutting both would be the best. Maybe you could try a ‘fat-free’ capuccino with a sugar substitute, like Splenda?
