Little things mean a lot.
Dietary changes don't have to be overwhelming to make a real difference in your waistline. By substituting a cup of 1 percent milk for a cup of whole milk, you'll save 50 calories and 6 grams of fat. Do this daily for a year, and you'll lose about 5 pounds. Spread a tablespoon of dijon mustard on your sandwich instead of mayonnaise, and you'll save 82 calories and 10 grams of fat. Do it twice a day for a year, and you'll lose about 6 pounds.
