No, there are many people suffering from obesity in any country in the world. I heard that there is a country in Europe, and losing weight accounts for one-third of the national household expenditure. If a product can have a little obvious effect, it is crazier than Apple's mobile phone and does not need advertising.
At present, there is no healthy slimming product in the world. I'm talking about mechanical physiotherapy.
There are also some ways to lose weight, which is hard to say.
