Reducing your intake or increasing your burn by 100 calories per day may be all you need to do in order to combat 'weight creep'.

According to the American Dietetic Association, the difference between weight loss and weight gain can be as little as 100 calories a day. Most Americans suffer from 'weight creep' - those nagging pounds that creep on over the years - at an average of about 2 pounds per year. That's 20 pounds in ten years. 40 pounds in 20. Can you afford to weigh 40 pounds more than you do now in twenty years?
