To stop gaining weight, we need to eliminate just 100 calories a day from our diets. You can do that by leaving a few bites of each meal on your plate, skipping that expensive nonfat latte, or eating one less cookie. You can also burn an extra 100 calories a day by simply walking one extra mile, which takes only fifteen to twenty minutes. And you don’t even have to do it all at once — you can break it into two ten minute walks. These easy strategies won’t cause you to lose a lot of weight, but they will help you stop gaining!
