I hope I didn't misunderstand your comments. But it sounds like you are talking about a starvation diet.
We hear so much about starvation diets failing. The best thing to do is to learn about a healthy diet and find some good form of exercising for you.
If you look at this as a long term solution, then I think you'll be happier. You could try your method, but I hope that you don't make yourself sick by overdoing it. If that starvation method works, it would be the first time that I've heard of it being successful - long term.
You should look at eating properly as a lifetime commitment. It's really this simple: Healthy sensible diet plus exercise equals a good manageable weight.
I lost my excess weight nearly 20 years ago, and have kept it off. So, I speak from experience. I know also how miserable it is to diet. I don't even like to hear the word "diet". I stay within my 5 pound range. I never want to go through that two year misery again (of dieting). So, I understand....
There's so many different conflicting diets out there, that make it so confusing. But I think a lot of them say to avoid the junk foods - like cakes, cookies, chips, ice cream, donuts, pastries, sodas, crackers, and most fast foods etc. You might want to start there.
Also note that when a person is cutting back the foods, you'll want to supply the body with the most nutritious foods available. It's so important to have these nutrients.
I wish you well. I hope I didn't go on too much.
