Rumors refuted:

First, let’s learn about obesity. Obesity can be divided into two categories: simple obesity and secondary obesity. There is no clear cause of simple obesity, but it may be related to factors such as genetics, diet and exercise habits. Also known as primary obesity in medicine, more than 99% of all obesity is simple obesity. The exact pathogenesis of this obesity is not well understood. Any factor that can cause energy intake to exceed energy expenditure may cause simple obesity. These factors include age, overeating, too little physical activity, social and psychological factors, genetic factors and adipose tissue characteristics. Therefore, if you want to control simple obesity, you must control it from the source, reduce energy intake, and increase energy consumption.

Secondary obesity refers to obesity caused by other diseases. Secondary obesity accounts for only 1% of obesity. To control secondary obesity, we can only first identify the cause and cure other diseases before losing weight. Otherwise, no matter how much weight is lost, the weight will rebound. It is not difficult to see that weight loss is a slow, whole-body process. If you want to achieve the maximum effect, even if you take regular weight loss drugs, you still need to control your dietary intake and perform appropriate exercise.

So can obese people achieve the goal of "losing weight wherever they stick" with a small patch? In fact, no matter what type of slimming patch it is, it needs to meet these three conditions: First, it must be achieved It is to absorb the patched medicine through acupoints or skin, that is, "transdermal absorption". In the United States, transdermal absorption technology is called "transdermal absorption system". It is a cutting-edge technology, which means that it is quite complicated. The key technology is skin Tissue, drug contact area, and drug ionization technology. Only by achieving this can drugs enter the human body through external patches.

The second is the drug ingredients. Currently, its active ingredients have anorexia and diarrhea effects. In fact, the drugs absorbed by the gastrointestinal tract are applied externally.

The third is to look at the absorption of the drug. The effect of transdermal absorption varies greatly among individuals. The skin is a barrier that limits the degree and speed of drug absorption. Most drugs can penetrate this barrier very quickly. Small. That is to say, even if this weight-loss patch uses highly effective drugs and cutting-edge transdermal technology, it is equivalent to oral weight-loss drugs, but it works slower, is safer, and causes less gastrointestinal damage. Generally speaking, the places where fat is most likely to accumulate are the places where it is most likely to be consumed. Drugs cannot help you lose weight wherever you want. It can only be said that combined with diet and exercise, weight loss patches can have a certain auxiliary weight loss effect.

But it is not completely impossible to lose weight wherever you want. You may not be fat, but there are always some local parts that are not in harmony with the overall body shape. Then you can try some local slimming methods. For example, if you want to slim down your arms in a targeted manner, we can prepare two bottles of mineral water to use as small dumbbells. Holding it in your hand, lift your arm so that your upper arm is close to your ear. Then bend your elbows and straighten your arms. 3 groups a day, 15 reps per group.

The easiest way to slim down your abdomen is to sit up. There is no need to sit up completely, it will be bad for the spine. While doing this, hold your ears with your hands. Putting your hands behind your head can cause damage to your spine. Do at least 3 sets of 20 reps every day.

There are also many small ways to lose weight locally, which are simple and easy to do and don’t take much time. We can consult with fitness coaches to learn the simplest and scientific tips for losing weight, but the most important thing is You have to persevere.

Friends who want to lose weight must keep their eyes open and do not believe in false or exaggerated advertising.
