W: I’m trying to lose weight by running, but all the exercise is making me feel hungry all the time. How can I feel satisfied without gaining weight?
M: (22)You’re burning more calories, so your body needs to take more in. First of all, get lots of healthy, high-fiber foods in your diet.
W: (23)1 think that most high-fiber foods require more chewing.
M: (23) Yes, high-fiber foods are usually tight so they fill up your stomach faster and can also delay the time it takes your stomach to empty. Also, many high-fiber foods are low in calories, so you can satisfy your hunger with fewer calories.
W: I like high-fiber foods. Could you recommend me some?
M: There are many options for you. Whole grains, vegetables, and fruits are great sources of fiber.
W: OK, I know, I’ll buy these foods in a supermarket this afternoon. What about other suggestions?
M: (24)You’d better choose smaller meals in the day. If you wait too long for a meal, you’ll be starving to eat more by the time you eat. Eating more frequent, smaller meals, such as five to six small meals, helps keep you full, and lets you stay in control.
W: It is said that never eat too quickly. The slower you eat, the more polite you seem. Do you think so?
M: Yes, but it is more than that. (25)It takes our body about 20 minutes to realize that it’s full. If you eat quickly, by the time your body realizes that it’s full, you’ve already eaten more than you needed. When you eat slowly, your brain will start sending signals to stop eating at the right time.
