I'm not afraid of fat a hundred steps before a meal

　　　　A recent study by British scientists found that taking a long walk before eating a hearty meal can reduce the adverse effects of fat intake on blood vessel function. This view is in sharp contrast to the traditional belief that walking after a meal helps digestion and weight loss.

　　According to a Reuters report on December 21, eating high-fat foods will temporarily increase the fat content in the blood. For example, triglyceride levels will rise significantly. Triglyceride is a type of blood fat that provides energy. If the content is too high, it will turn into fat and be stored in the body. Absorbing excess triglyceride for a long time will increase the risk of coronary artery disease. disease dangers, so it is considered a "bad" cholesterol. Many studies have proven that high levels of cholesterol and triglycerides are risk factors for obesity and risk factors for heart disease and stroke.

　　--Whether it is for people of normal weight or obese people, and this method is especially effective for obese middle-aged people. The research results were published in the "Journal of the American Cardiovascular Society" published on December 21.

　　According to this study, 10 normal-weight men and 10 obese men were used as experimental subjects. They ate a very rich meal, which included high-calorie foods such as whipped cream and chocolate, and 80 grams of fat. The experiment was completed over two days, and the subjects ate exactly the same meals each time. The only difference was that on the eve of one meal, the subjects ran on a treadmill for 90 minutes, while in the other case, they did no exercise the day before. exercise physical activity. As a result, the researchers found that if they exercised before eating, their blood triglyceride levels increased very little after the meal, and their blood vessels worked much better than after eating without any exercise before the meal.

　　Of course, the lead expert on this study, Dr. Jason Gill of the University of Glasgow, UK, also said that the results of this study are not telling people that those who exercise regularly can eat a lot of high-fat foods without any scruples.
