LindaMy husband weighed 275 pounds. He used to skip breakfast, and he didn"t eat all that much for dinner. So I once wondered why he was getting so big. Then I found out he was stopping to buy a dozen chocolate-covered doughnuts each morning. And you know how I found out He was eating them while driving, so he wouldn"t have to share them at work. While chasing one that roiled across the front seat, he ran into a telephone pole.EmilyTwo years ago, I knew my husband"s health was at risk because of all the weight he had picked up since we"d been married. But he wasn"t doing anything about it. Then I went to a doctor"s office and I followed his advice and started talking about food to my husband-what was good, what was bad-as if it was a new discovery. I didn"t lecture my husband about the evils of being overweight, didn"t try to threaten him by saying if he didn"t lose weight his blood pressure could shoot sky-high and he might have a heart attack. Instead, I talked about how well he"d look in new clothes, how he" d probably do better on the job (he was a salesman), to ask questions. After a few months, he"d lost 20 pounds.JohnI once kept a list of everything I ate one week, just to show my wife was wrong about where I was picking up extra pounds. When I studied my list, I wondered how I found time to do any work, I was eating so much. There"s nothing like seeing it in black and white to prove you"re wrong.Jane ScottWhen I found my husband had weight problem, I was determined to take some measures. I made sure I needed something from the store three mornings a week, and then I told my husband I didn"t want to walk there alone-it was about a quarter of a mile each way-and I"d always insist on walking. He breathed hard at first, but gradually got used to it, and we started making a circle around the neighborhood at night, too, with the dog. That was three years ago, and now I can"t keep him still. The walking got him used to using his body again, and he was happy to find it still worked pretty well.TedMen tend to think less about the costs of excess pounds than women do. Men often seem blind to the possibility that a beer belly is causing them to look unattractive to their mates, holding them back in their careers and killing them before their time. Also, many men feel self-conscious going to a diet center-especially if most of the group is female. Diets are perceived to be of women"s concern, or an admission of weakness. There are even men who would rather blow up like a blimp before they admit to other men-or themselves-that they need to lose weight.Now match each of the persons with the appropriate statement.Note: there are two extra statements.StatementsA. The heavier, the merrier.B. Some form of physical exercise has to play a part in men"s weight-loss program.C. Attention should be paid to eating patterns.D. Men"s attitudes are quite different from women"s.E. Gaining weight has nothing to do with health.F. Your educational role sometimes has to be more subtle.G. Facts are indisputable. Jane Scott
