Most heavy people don't really eat that much at meals, but they are in the habit of grazing between meals. Without realizing it, they ingest a large number of calories. For this reason, weight loss centers require their clients to keep an "eating journal" -how thick was the butter on that bread? How much sesame? -all the details must be faithfully recorded.
一般胖人正餐通常吃得並不多，但習慣東吃西吃，不知不覺地吃進一大堆卡路里，因此每一家瘦身中心都會要求客人寫「飲食日誌」﹘﹘麵包上有多厚的奶酥、多密的芝麻，都要鉅細靡遺地誠實登錄。
