Again, I apologize, because now I think I get what you mean, but I don't know much how to advise you as I really don't know anyone who's tried to lose weight in the manner that you have.
I think you will find majority of us here are looking for longterm,
permanent weight loss - not necessarily
rapid weight loss. We'd rather it take a little longer to come off - and then not come back
.
From what it sounds like to me, that's not the case with you. Eating less then 1000 calories is not sustainable for any length of time and then eating just 1000 calories is also not something that anyone can do for any length of time. So therefore more then likely, it doesn't provide you with much weight loss at all in the end if you can't keep it up. If you can't keep continuing it - well then - you gain it back. Not so rapid afterall. Again, most of us here are looking for longterm solutions, not quick fixes. We eat healthy foods in healthy portions (calorie allotments). We can do if for months and years on end, thus allowing us to lose the weight - and keep it off.
I hope you find some answers. All the best.
