Weight - Loss Products: Miracle Cures or Marketing Tricks?

All along, BMI has been the main indicator for judging obesity, which is calculated by dividing body weight by the square of height. However, this method is too simplistic. It can't distinguish between fat and muscle. Those with well - developed muscles may be misjudged as obese just because of a high BMI, but in fact, they are very healthy. In January this year, "The Lancet Diabetes & Endocrinology" put forward a new view. Judging obesity cannot rely solely on BMI. It also needs to consider body fat, waist circumference, and see if there are symptoms such as reduced organ function and decreased daily activity ability. They proposed the concepts of "clinical obesity" and "sub - clinical obesity" and formulated corresponding diagnostic criteria.
Next, let's talk about weight - loss products. Nowadays, there are a wide variety of weight - loss products, but few of them are reliable. In our country, only 5 drugs are approved for weight - loss treatment of adult primary obesity. And specific conditions must be met to use them. For example, the BMI must be high enough, or there are related complications, and lifestyle interventions have little effect. Take semaglutide as an example. Although it has a good weight - loss effect, there are adverse reactions and many contraindications. Not to mention those "miracle weight - loss drugs" on the Internet. Many of them contain prohibited ingredients and are toxic and harmful. For popular weight - loss products like enzymes and L - carnitine, there is no basis for weight - loss. Enzymes can only help with digestion, and the human body can produce enough L - carnitine on its own, so there is no need for extra supplementation.
So, answering the questions at the beginning, our definition of obesity has indeed changed. It no longer only depends on BMI but also takes many factors into consideration. As for weight - loss products, most of them are marketing scams. The truly effective drugs have strict usage standards and are not available to everyone. So, don't be fooled by those fancy advertisements. The right way to lose weight is still through a scientific approach, such as controlling diet and strengthening exercise. Don't expect to "lose weight effortlessly" by relying on unreliable products.

Hey, as we all know, the obesity problem is getting more and more serious globally these days. It's closely related to our health. So, has our definition of obesity changed? And what about those numerous weight - loss products? Can they really help people lose weight, or are they just marketing tactics used by businesses?
Let's first talk about the definition of obesity. In the past, people generally thought that being fat meant having an excessive body weight. But now, we know that we can't just look at the weight. Body composition also matters a lot. For two people with the same weight, one with more muscle and less fat and the other with more fat and less muscle will have different health conditions. Moreover, the impact of obesity on the body also needs to be considered. For example, some people have a very large belly, which is called central obesity. Even if their weight is not extremely high, it still increases the risk of heart disease and diabetes. So, the definition of obesity has become more comprehensive. It no longer just focuses on the weight number but also takes into account factors such as body composition and fat distribution.
Now, let's look at those weight - loss products. There are so many of them on the market, such as weight - loss teas, meal replacements, and slimming creams. To be honest, many of these products lack scientific basis. For some weight - loss teas that claim to help you lose weight just by drinking, they actually just make you have diarrhea and expel the water in your body. The weight drops temporarily, but it has no effect on fat and may even affect intestinal health. And those meal replacements, if you occasionally use them to replace a meal to control calorie intake, it might be a bit helpful. But if you only eat meal replacements for a long time, your body will lack various nutrients, which is not good for your health. As for slimming creams, the idea that you can lose weight just by applying them to your body simply doesn't conform to human physiology. It's just hype by businesses. Of course, there are also some formal weight - loss products, such as some weight - loss drugs with scientific formulas that have undergone strict clinical trials. However, these drugs also have strict usage conditions and side effects and are not suitable for everyone.
So, the definition of obesity is indeed changing, becoming more scientific and more concerned about overall health. And most weight - loss products are marketing scams. Truly effective products need to go through strict verification and should be used under the guidance of professionals. Everyone, don't blindly believe those exaggerated advertisements. Losing weight still requires a healthy diet and regular exercise. This is the most reliable way.
