When I was younger I dieted down to 108lbs and had no period for a year. I was not ripped by any means. It is probably not genetically possible for me. Nowadays I'm lifting heavy weights and I'm growing out of my clothes. I seem to be one of those people who may be blessed with the ability to put on muscle, but cursed with a relative inability to take off fat. I have no illusion that becoming "ripped" would be anything but a severe and damaging thing for me to do.
What all these ripped men had to do, I do not know. I've been hanging out in some of their forums (god it's been so boring at work) and a lot of them sound like crazy women with the shit they believe in. I have no idea who Martin anybody is, what they actually did to get where they are or what, but anybody who comes here and asks if getting ripped is even healthy probably can't get ripped simply by being healthy in which case the answer is that it probably isn't healthy.
I think that Mark (Sisson) has done a relative disservice with a lot of his success stories showing women in their 50s with 6-pack abs and people whose fat just "melts" right off to a perfect 6-pack. I'm sorry but it doesn't happen for a large number of us. For men, it's not even necessary for health. It's purely for vanity.
