     It's 8:00 pm. You are sitting in front of the television and feel like some chocolate ice cream. You can't

stop thinking about it. If you can't find any in the fridge, you may even go to the shop to get some.

     We all have those strong wishes for delicious food like ice cream, fast noodles, or fried chicken. Eating

a little is not bad for your health, but eating too much can give you weight problems. So how do you stop

yourself from eating more? Experts (专家) have some easy ways to get over your cravings (抵制诱惑).

     Let them pass. Studies show that the cravings last only about 10 minutes, so try to wait for a short time

to let the cravings pass before you walk into the kitchen or to the shop.

     Eat less at a time. You need to care about how much you are eating. Try to eat only a little bit of food at

one time. For example, put potato chips in a small bowl and just eat those in it.

     Eat healthy food. Try to eat a similar (相似的) food that is healthier than the one you want. A glass of

milk is better than sweets. Or, low-fat yogurt (酸奶) is healthier than ice cream.
