wont do anything at all unless you're sick and trying to pee yourself well or you're upping your liquid intake because you're constipated and trying to get things moving. LoL.
The "benefits" you're talking about are achieved after a long period of fasting where your body goes into Ketosis, but like Elwing said -- the cost is that while your body is being "purged" your muscles are the first to go. Not fat. That's why a lot of girls on super restrictive diets have cellulite despite being so skinny.
HOWEVER -- You can also put your body into Ketosis by eating a super high proteins/low carb diet like Atkins. That's how that diet works. I think Walgreens even sells the litmus sticks you use to test your pee to see if your body is in Ketosis.
Back when I was till doing ballet to maintain my absurdly skinny 105lb performance weight I used to eat nothing but 400 cals a day for two weeks, and then do a total fast (nothing but water and a vitamin) for 30 days. Just enough to keep me going, but now my metabolism is shot -- I can't process proteins or fats normally, my bones are brittle, my pulse and BP are abnormally low, and my body won't absorb the vitamins and minerals it needs from what I eat. I have virtually no potassium or sodium in my body so my weight fluctuates like crazy and i'm at high risk for heart problems. Your body is able to fast, like all animals, but you should only do it in emergencies.
You're doing good, so just stick to it.
