Yangcheng Evening News Reporter Liu Xinyu and Xue Renzheng reported that May 11th is the World Obesity Prevention Day. The "meal replacement diet" is particularly popular in spring and summer every year. According to the data of "Shop Monster", the daily sales volume of meal replacement products can even reach 100,000+,and the unit price ranges from 28-140 yuan. Many netizens who tried to lose weight with meal replacement products said that they didn’t lose weight after eating many meal replacement products and spent a lot of money. The reporter interviewed Deng Yuhong, director of the Clinical Nutrition Department of the Second Affiliated Hospital of Guangzhou Medical University, and obtained the "meal replacement" data of 145 obese people to see the real effectiveness of meal replacement to lose weight.
Data:
Meal replacement is really effective in losing weight.
Deng Yuhong introduced that in hospital clinical practice, meal replacement (mainly in meal replacement powder) is indeed an auxiliary means to lose weight.
This assistive device was also completely recorded by her team and published in the journal of General Medicine of China. The team took 145 patients (36 males and 109 females) who came to the hospital from June 2015 to January 2017 as the research object, with an average age of (34.2 10.9) years and a body weight of (81.09±15.84)kg. 28.0kg/m2）。
The whole weight-loss experiment lasted for six months, and the purpose was to study the weight-loss effect of the diet mode with low carbohydrate and high nutritional density. Among them, in the first three months, the low-carbohydrate mode was adopted, that is, rice flour and other high-starch foods were restricted. In order to reduce hunger, meal replacement powder was used together. After three months, the success rate of weight loss was 60.0%, which produced obvious early weight loss effect.
"Whether it is psychological or substantive, from the clinical observation, the role of meal replacement in weight loss is indeed not small." Deng Yuhong further explained that first of all, meal replacement has a sense of ritual, reminding himself that "now I am losing weight and can’t eat more". Secondly, increase satiety and reduce appetite. Meal replacement powder generally adds konjac flour, whey protein powder, soybean protein powder, dietary fiber, etc. Of course, some fats and carbohydrates provide basic calories, which can fight hunger after eating.
Reminder:
Long-term blind eating meal replacement has side effects
It is worth mentioning that this study tried to follow up patients after one year, but the loss rate was too high. It is pointed out that the patient’s withdrawal may reflect the patient’s intolerance to this dietary pattern. Deng Yuhong also said that in fact, in the actual research, the loss rate of weight loss projects has been high, ranging from 15% to 50%.
Deng Yuhong said that the ordinary balanced diet pattern is the long-term eating habit of Chinese people. Once it changes, such as reducing staple food, it begins to try "half-generation meal" (instead of one meal) or even "full-generation meal" (instead of all meals). The stronger the degree of intolerance, the weaker the execution, because people are born to pursue diversified diets and everyone’s physical condition is different, but the weight loss gimmicks of businesses are often "simple and rude".
"For example, there used to be a company that made meal replacement food, which required that every meal must be meal replacement, only 700 calories a day, and it must be eaten for a month, which of course would be thin. But the problem is that most people will fall into ‘ Yo-yo ’ Effect, eating meal replacement, the overall intake of calories is less, and the weight is down; Stopped the meal replacement and gained weight again. The harm caused by the rebound is self-evident. "
Doctors remind that the cost of educating the masses is often high, especially it takes time and energy to let everyone know about the dangers of obesity and popularize how to eat a balanced and healthy diet. However, many businesses often skip this step. In order to maximize profits, they often take advantage of people’s weakness of wanting to lose weight in the short term and publicize the effectiveness of weight loss products. They need to be more vigilant and do not recommend sacrificing health. After all, many meal replacement products have very few calories, and there are many side effects in the long run, especially women are prone to endocrine disorders and anorexia.
Doctors suggest that ordinary people can check whether they are really obese by calculating BMI and going to the hospital for physical examination, ignoring this step and blindly losing weight with the wind, thus damaging their own metabolic rate, which may have been superior, but it is not worth the candle.
