I think it works. Adhering to this diet for a long time is still useful for people to lose weight. Because people eat less oil and salt, they won't gain weight, but because there is no food in their hungry stomachs, they will burn fat, which is also a way to lose weight. However, eating fat-reducing meals alone sometimes does not make the weight loss effect obvious, and exercise is needed. The combination of the two will make the effect more. But for people who are not too fat, they can also lose weight by eating fat-reducing meals. They are not very fat, but they have perfect requirements for their bodies, so they can make themselves thinner by insisting on eating fat-reducing meals every day. Fat-reducing meals are still popular in schools, because many students will slim themselves down first, so they will let themselves eat fat-reducing meals, and they often eat them in the canteen, and some meals will feel bored. When a new product comes out, they will be very curious. If it is delicious, it will be very popular. However, some students eat fat-reducing meals and other things, which will not be effective, because you don't eat them to lose weight, you just regard them as a kind of meal, and when you are not full, you will eat other foods, which will not achieve the effect of reducing fat. If you just eat fat-reducing meals, pay attention to your diet at ordinary times, and don't eat those greasy and puffed foods, so long-term persistence will still have a fat-reducing effect. But the effect will not be so immediate, just saying that I won't make myself fat again. As for serious weight loss, exercise is still necessary. You need to do a certain amount of exercise every day in order to lose weight. And losing weight is a long-term project. Losing weight can't be done for a while, it takes a long time to be effective. So since you want to lose weight, you should plan well, control your diet, need a certain amount of exercise every day, and come slowly by yourself.
