Alas, eating more of these vegetables and fruits can only be said to be good for your health. Even if there is a slimming effect, there is no trace of slimming at all. Eating so-and-so vegetables or so-and-so fruits will make you thin.
I have never heard of such a thing. The key is diet and exercise, but some lazy people will buy slimming products! For example, I am a living example: I am too lazy to exercise, too lazy to diet, and I am thin by slimming products.
