You can lose weight if you don't simply eat anything, absolutely not, otherwise there won't be so many fat people.
No matter whether this star diet is good or not, most of the weight lost is water, not fat, and the body fat rate is the most important. People with the same weight, the higher the body fat rate, the fatter they look, and the lower the body fat rate, the thinner they look.
Losing weight is always keeping your mouth shut and your legs apart. You must eat three meals a day, but you can naturally lose weight if you have a diversified diet, drink more warm water, be 7 minutes full and take anaerobic aerobic exercise.
All diet pills do great harm to the body, especially the kidneys. People who take diet pills get uremia everywhere, and it is irreversible. You can't make fun of your health.
I hope my answer can help you.
