I am a former collegiate football player. In college I bulked up to 225 lbs, 52 inches at the shoulder, 42-44 inches in the chest, 32 inches at the male waist, 28 inches in the thighs, squatted 550 lbs, benched 300 lbs. Right after college I dropped down to a fit 185-195 lbs range (15% fat range), where I remained right up until a couple years ago I reawakened to the fact that I was transgender. I consistently worked out most of my adult life and, to a lesser extent, ran for fitness (and the occasional 10K). I am now a fit, relatively lean 50 year old MTF in transition. Even before hormones I began to try to lose weight by switching my exercise regime from male-ish to female-ish (March 2014). Basically, I switched from a relatively lower number reps with heavier weights to a higher number of reps with lower weights. My exercise routine now includes circuit training 2x/week, stair climber (15 mins) and running (20 mins) 4x/week, and yoga 1x/week. I started estrogen injections four months ago, and it crashed my testosterone levels toward the low end of female (two blood panels - one at 13 and the other at 31). My buttocks (41 inches vs. 39) and hips (41 inches vs. 39) seem to have expanded by about 2 inches over the period, which is great. But my chest (41 inches), bust (42.5 inches), rib cage (39 inches), female waist (35 inches), and thighs (24 inches) have remained the same. My weight has varied from 182-189 during the period under injections, with no particularly obvious trend going down or otherwise. I have been living full time since August last year. I just finished my first really major clearing of facial hair - after 6 months' intensive laser and electrolysis - such that my facial skin shows no hair or a smidge of vellus hair and is pretty smooth. My eyebrows look pretty good. I haven't yet had FFS, but plan to do so Q1 2016. I'm using my femme voice out and about. I think I powder my face and apply lip coverage pretty well. OK, getting to the point, I'm still greeted as sir. I think the tell is my body rather than my face. So, I'm terribly concerned that I may never get my body to shrink to pretty femme dimensions, even if I ultimately get to the point where I pass. (Sorry, maybe I have no right to be vain at age 50, but I cannot help it.) In any case, my internist / endocrinologist has indicated that I need to lower both my total calories intake to a sustained but liveable deficit and my protein intake without triggering a catabolistic atrophy. And/or just outright stop working out - even my femme exercise program. I have had a hell of a time trying to adhere to a portion control program. For some reason, it's easier during the week than over the weekend. And I desperately don't want to give up my circuit training. I would like to seek anyone's advice who has had to slough off muscle, who has not had a problem with fat reduction, and who has done so at my age approximately. Is there a proven path? If it's portion control, please please please tell me how I can discipline myself to not only get there but also to maintain it for the rest of my life.
