RL, my comments about healthy weight loss relate to someone trying to train up for SF enlistment/candidacy in September while trying to lose weight in a rapid fashion by restricting their caloric intake. That is what Kyo's thread addresses.
I doubt Jarod finished his rapid weight loss period with the fitness/strength/endurance required to succeed in the SF pipeline. Kyo's thread is focused on that particular need as well.
That makes the process much more difficult to obtain, if at all..
