I'm sure you can do your own research and find the information. There's plenty of it out there, and I'm not your research assistant. That's not a cop out, I'm just not into posting links that you're going to pick apart and argue about ad nauseum
You don't need to be a rocket scientist to figure out that the effects of no nutrition for a long period will royally screw up your electrolytes, insulin, cause muscle loss, which includes your heart, effect your brain and ability to think clearly and rationally (I'm not talking about the feeling of clarity people say they feel during a short term fast)
There's some evidence short term fasting is beneficial, but that's not what you're going for.
You might want to remember when you attempt not to take any nutrition into your body for a month, that your body is now 8 years older than when you tried this last time. Regardless of what kind of shape you're in, your body is older, it will be more likely to have problems, and whether you succed or fail the recovery will be more difficult, and you're not going to be doing yourself any good.
The only way to attempt such a foolhardy exercise would be under close medical supervision. That is if your doctor/nurse practioner, etc. doesn't convince you that you're playing a dangerous game with your life.
I have no more to say on this.
