This is not a diet. It’s a simple way to lose weight. And you don’t even have to give up the food you love or join a gym. You just follow some habits that thin people have. Keep them , and you’ll become thin. ( 1 ) Wake-up When you wake up in the morning , sit up slowly without using your hands. With legs straight out, bend (弯曲) forward until you feel sore in your back. It will burn about 10 calories (热量单位 : 卡路里) . ( 2 ) Start with soup When you have a meal, order a clear soup, and have it before having the main food. In this way, you’ll feel fuller, so you’ll eat less when the main food comes. ( 3 ) An apple ( or more ) a day Apples are full of fiber (纤维) and water , so your stomach will want less food. The study shows that people who eat at least three apples a day lose weight. ( 4 ) Stand up and walk around Every time you use the mobile phone , stand up and walk around. Heavy people sit on average (平均) two and a half hours more each day than thin people. This skill is very important , as standing up and walking around will burn 50 or more calories. Use these skills, and you will have a big weight loss.
