How fast can you lose weight by throwing up you know that is bad but you need to know?

Answer 1

As fast as you would lose weight by starvation, since you're effectively not eating. If you make yourself throw up enough times, you'll lose the capability to throw up altogether. Then if you get sick, you won't be able to throw up and you might die. Dead people don't lose weight, so losing weight by throwing up is counter-productive and pointless.

Answer 2

The erosion of enamel on your teeth begins immediately from stomach acids in the vomitus. If vomiting is regular, you could permanently damage your teeth.

Throwing up to lose weight is an ineffective weight-loss technique. It primarily discards gastric fluids. It does NOT remove fat cells from fat tissues. You would be very sick before the body turns to its own fat reserves for energy.

A far better plan is to walk every day and do other exercises at least three times a week. If done properly, you should expect 1 to 10 pounds of weight loss in the first week (mostly fluid weight), then 1-2 pounds each week thereafter. If you combine exercise with healthy foods, you will lose weight and tone muscles. The body will naturally begin to burn fat cells with increased exercise.
