Some say it can stall weight loss. Maybe avoid it until you reach your ideal body composition. I don't see why it can't be a good part of a maintenance diet.
"I know what my body needs and what it can handle. There's no better way to achieve my goal than what im doing now. If my regimen leads to my death, be it in six days or six months...I will die fullfiled. The outcome is irrelavent so long as i steer towards my fate. If death is to be my prize, i welcome it with open arms."
