Losing weight, for obese patients, losing weight is what they want to do most. What is obesity? What are the health risks of obese patients? How does diet prevent obesity in daily life? Let's listen to Chen Wei, a nutritionist at Peking Union Medical College.
Netizen question: Many friends hope to reduce blood fat through diet control, so as to achieve the purpose of losing weight, and think that the only way is not to eat meat or oil. Is this desirable?
Nutrition-Sir Chen: Diet control is really effective for some people with dyslipidemia. Meat is the main source of protein and plays an important role in maintaining the normal metabolism of the body. Not eating oil at all will lead to the lack of essential fatty acids. Diet intervention and drug treatment when necessary.
Netizen asked: I feel fat, but people around me say that I am not fat. Is there a formula to calculate whether I am fat or not? There are also such formulas on the internet, but the algorithms are different. Which is accurate?
Nutrition-Sir Chen: At present, the most commonly used method to judge obesity is that body mass index = weight (kg)/ height 2(m), which is just a simple method to judge obesity. When the increase of body mass index is caused by the increase of skeletal muscle, there is no need to lose weight.
Netizen asked: For the average person, how to reasonably arrange the food for three meals is healthy and nutritious, without getting fat or losing fat?
Nutrition-Sir Chen: For the average adult, three meals include staple food, vegetables and protein (meat, eggs, milk and bean products), so the specific intake should be individualized. Properly control the intake of oil and salt and increase some moderate exercise: mainly aerobic exercise.
Netizen asked: How to lose weight when you are strong and fat?
Nutrition-Sir Chen: Proper aerobic exercise, 65438+ 0-2 times a day, 40-50 minutes each time, may help you.
Netizen asked: Some people say that eating a good breakfast and lunch and eating only one apple for dinner can reduce weight. Is it true?/You don't say. Science?
Nutrition-Sir Chen: I can definitely answer you that this diet is unscientific and may have the effect of losing weight in a short time, but after a long time, problems of one kind or another will appear. About losing weight, we must be individualized in order to achieve the goal of losing weight scientifically and healthily. This belongs to hunger therapy. Absolute weight loss is not sustainable for a long time, and it is absolutely unscientific. I hope to lose weight by scientific and nutritious methods.
I remind: dieting, taking diet pills and other weight loss methods are not reliable. Only through normal diet adjustment and proper exercise can we really lose weight. Therefore, for obese people, if you want to lose weight, you can't rely on diet pills or dieting. Only healthy weight loss is weight loss.
