This is not a diet (减肥食谱) or a hard ~exercise program. Nobody can stick to those for long. Instead, it's a simple way to make weight loss a natural part of the life you already live. And guess what？ It's fun! You don't have to give up the foods you love or do regular exercises. It's about balancing calories(平衡卡路里) in tiny ways that add up to big benefits (好处). You just use some tricks the "naturally thin" people do. Pick the ones you like, stick with them, and you'll lose weight and be strong!

Think about your drink Consider beer or wine instead of a frozen drink: A glass of regular beer has 140 calories and a serving of wine has 126 calories, while a strawberry daiquiri has about 300 and a margarita 340.
