I checked my body fat % with one of those handheld checkers today and used its results to calculate my lean muscle mass. I did this in May/June at around 290lbs and had a lean muscle mass of around 193. I am 268lbs right now and, according to today, have around 183 lbs lean muscle mass. I don't like the thought of losing muscle, but should I be concerned?
Diet: 90+% paleo (primal variant, includes some dairy--mostly cheese, and Lindt 90% chocolate 2x/week or so)... probably much higher than 90% in actuality, but food is conventional, not grassfed/organic/pastured, etc which knocks it down a bit and I like cheese
Exercise: Predominately walking, maybe 7-8 miles/week at a slow pace. Occasional jog/walk intervals, very occasional sprints, wrestling on the floor with the kids every other day or so. Did the insanity fit test this morning; that about killed me.
Proportionally, I am still much higher muscle:weight ratio than I have been in a long time, but I don't want to get down to 215lb only to have another 30lbs+ of fat still to lose.
