    61.        You should watch where your weight accumulates. You can use the waist. to. hip ratio to find if there is too much fat around the middle. Belly fat is especially dangerous because it release free fatty acids directly to the liver, virtually flooding it with fat.
    62.        If a particular food is important to you, eat it, but work it off. You should try to learn the art of compromise.
    63.        At the same time. the three-for-one is relatively simple to use. Fat grams and calories are listed on almost all boxed, canned or packaged foods—you have only to read the label and follow the rule. A five-year-old patient of mine can do this.
    64.        Drinking water is basic, and drinking enough of it is necessary. Patients are sometimes surprised that basic things work when they do them consistently.
    65.          Consume antioxidant foods. They protect the cholesterol C胆固醇), from oxidative damage, which helps prevent damage to blood…vessel walls.
    A. More than nine years ago I was 70 pounds overweight and wore a very big dress. I had tried different diets and lost weight only to gain it back. Finally a simple “three. for. one’’ fat rule worked for me:consuming no more than three grams 0f fat for every 100 calories per serving. Following the rule and eating only foods that contain less than 30 percent fat, I spent eight months getting down to a size seven, and I’ve kept the weight off for nine years.
    B. And for foods that aren’t packaged, you rely on what we already know about them. Red meat, as well as dishes made or served with butter, gravy, cream sauce or cheese, are almost never less than 30 percent fat—so you just don’t eat them. On the other hand, some non-packed foods—all fruits and vegetables。except avocadoes and olives—always pass the test. So do most fish。but not when fried.
    C. I like vegetables, which are rich in vitamins. Most foods containing vitamins C and E(such as sweet potatoes, tomatoes, spinach and broccoli)are low in calories and are known as antioxidants(抗氧化物质). They can help reduce the possibility to develop hardening the arteries(动脉).
    D. I gain weight around the belly—what we call abdominal obesity, the worst kind. The tendency seems to be hereditary(遗传的), and it’s common among men. This problem increases the risk of a stroke or heart attack. A guide I use in estimating belly fat is the waist-to—hip ratio, or WHR. To find yours. divide the circumference(周围)of your waist by the circumference of your hips. Women with ratios above 0. 8 and men with ratios above 1.0 are at increased health risk.
    E. My ways of keeping healthy are very simple, and they are among our everyday activities:eating healthy food and doing exercise. In addition. I manage to do those basic things, such as drinking water, sleeping well and eating less fat. Sometimes I do some of the other things I used to do in my life like walking for half an hour a day.
    F. Although I've put on ten pounds. I'm healthy and in good shape. I eat food that’s good for me…but 1 work off Susan’s homemade brownies(巧克力蛋糕), for example. To offset these extra calories, 1 walk for an hour or more, three times a week…often with Susan. We’re both busy and this is one way we have some quiet time together. Equally important, it permits me to practice dieting’s fine art of compromise.
