I feel like it's important to point out at this stage that some of the "dietary" advice being given here is ranging from inadvisable to downright dangerous. I mean... it's your body, do what you want with it, but I have to say draw a line at encouraging other people to do it.

If you want to be a healthy weight and feel good, eat whole grains, fruit, veg, nuts, seeds, legumes and lean protein and stick to that permanently. Crash dieting is dangerous and daft no matter how many internet articles tell you otherwise, and (as the people advocating it seem to be freely admitting??) almost always leads to a relapse into unhealthy eating.

Again do what you want with your own body but stop suggesting to other people that it's a good idea. It's reckless.
