Because this is a weight-loss advertisement, if it doesn't work, people won't believe that this institution or weight-loss products can lose weight. People in advertisements lose weight quickly, which generally means that they will lose a lot of weight in the short term. There are many factors in this.

First, there are different reasons for obesity.

Some people are obese, that is, people who drink cold water will get fat. It is not easy for such people to lose weight. However, some people tend to get fat because they eat more and exercise less, but because these factors can be controlled, they can eat less and exercise more, and they will soon lose weight. Therefore, the people selected in the advertisement are likely to lose weight easily.

Second, the means of advertising

The audience doesn't know the people in the advertisement when they watch it. Maybe this person is not fat at all, but in order to promote the effect, I made this person fat and put a real photo on it. By comparison, I found that this person has a good weight loss effect. These are the needs of advertising, so that everyone believes that as long as they eat this product or join this organization, they will definitely lose weight and achieve perfect results.

Third, lose weight recklessly.

In order to produce advertising effect, we may use some drastic measures to lose weight, such as vomiting or fasting, regardless of the health problems of subsequent participants, as long as we ensure that people lose weight within a period of time. After the advertising effect is achieved, the subsequent health problems are ignored. But we are ordinary people, we can't use such extreme means, we must lose weight scientifically.

Therefore, if you want to lose weight, you must lose weight scientifically, adjust your eating habits, formulate exercise strategies, lose weight without sequelae, and don't blindly believe in advertisements.
