It does not work very well. You will lose weight at first, but the body metabolism changes to adapt to the low nutritional intake and weight loss slows dramatically. You will still lose fat, but are losing many other needed nutrients too.

There is no substitute for a moderate diet and exercise. NONE.

 Huh? I always thought the body would stop losing weight and try to hold it's fat as an auto response to no nutrition. I've read that you will lose muscle before you lose fat, if you don't try to lose weight properly. Maybe you should see a nutritionist.

 Yes diet

 It doesn't work ,i know from experience,i would starve myself and not eat,would lose weight at first then eventually the weight loss would stop and come back most of it would be water due to dehydration,it ruins your metabolism and makes you hold weight even today when i eat one meal and one snack a day,my weight will not go lower than 145 to 150 and I'm 5 foot 3 so that's not skinny,when you starve yourself you'll also come across a no control point where you'll been because your body is so hungry dieting and starvation does not help you lose weight and keep it off ,only proper nutrition and reduced calorie intake ,(not skipping meals,)and exercising are the only ways to lose weight,a proper diet equals a healthy weight starvation is not healthy or pretty,your body was meant to have food that's why god gave you a digestive tract

 It is never good to starve yourself.

 No no !! You can kill yourself like that /i had a friend that did this and when she end up at the hospital she could not pass down none of the foods she enjoy before she got sick /she regrets it so much that she rather eat healthy and exercise/but unfortunately she pass away /she developed some complication with her skin and she could not go out in the sun and one day she went out with another friend of hers and she told me that she just want it to feel the sun ,went out and collapse

 Starving can give those weaknesses which can be very difficult to lose.
But, It really helps to lose more pounds, I tried it and suffered too. But alright now after so many years of trying.

 Starving yourself is very unhealthy to lose weight. For your body to function you have to have food.. The food gives the body nutrients and with out it you can die and become weak!

 There are health risk in concept of starvation. If you can provide evidence stating otherwise, it would be most welcoming. You may lose weight but is not the best course of action. Lack of food consumption will lead to low nutrition intake. It is imperative that one gets the proper daily nutrition needed for proper bodily function. There are dire consequences with starvation and I highly recommend you stray from that path(assuming that is what you are considering).

 No, I used to be anorexic, and I was very near death when I decided to get help for it. I was having heart palpatations constantly, and I was dehydrated. There is no benefit to starving yourself.

 Certainly not. Not only does it not work, it poses serious health risks. Once the body stop receiving nutrients in the form of food, it begins to break down body tissues in order to get nourishment and to provide energy. One loses muscle mass and becomes weak. Vitamin intake decreases and permanent organ damage can occur. Don't try it.

 Dieting never says starving...!
Dieting thrills at the end..but starving kills man!

 I tried starvation ad it didn't work for the reasons in the answer below
