Going that low (600-800cal), puts your body into starvation mode so it wants to hold onto every calorie & every fat cell it can because it doesn't know if its going to have enough to survive on. YOu can actually start causing damage to internal organs by going too low- I have a GI condition that causes chronic nausea & vomiting. At one point, I was hospitalized because I couldn't get enough in- I was on IV fluids that had some nutritional value plus what little I could take orally so I was probably getting about 600 calories. Eventualy after a few days, my blood work showed my body was breaking down its own tissue and damaging my kidney so I was put on a feeding tube that bypasses my stomach. I still had a hard time with nausea & vomitting, plus I was limited on how many calories I could take in via the feeding tube so I had to have my blood work run frequently to make sure everything was okay. Anytime I ran into problems and got below 1000-1200 calories per day for more then a few days, I started getting bad test results.
Another problem with going that low is that you typically end up eating an extremely low fat diet- our bodies need some fat to be healthy. That is not saying we need the fat that comes in a donut, but fat from an egg yolk, nuts, etc are needed to be healthy. I bet if you up your calorie intake that you will feel better and lose more weight- and be healthier overall.
