I had all of the health problems you mentioned. I actually thought I might have chronic fatigue syndrome because I could not move out of bed in the morning. I could not think either... it was like my brain was canibalizing itself. I subsisted mainly on soy meats and sugar. My hair fell out too, and I had awful acne.

Now that I am low-carbing I have a ton of energy, my hair is thick and glossy, acne is gone and I am back to my old self.
