I never considered that. I lost almost 40lbs about four years ago and it was very easy. I basically just started eating better. I quit junk food and fast food. I have been able to maintain my weight with almost no effort. So I guess I foolishly assumed my quest to drop another few pounds wouldn’t be a big deal. I hope I’m right! We’ll see...
I also have lost 30-40 lbs a couple of times in my life. I have kept off for a long time the obese condition I was in at +170-190, but without TRT I tend to be about 165 lbs.
In my 40s I took up running and a diet, got up to run 5 miles and my weight dropped from 160 >133. But soon after that I quit, and I think that is also when my total T took a dive down to 347 ng/dl. Maybe the lower T caused me to quit, at the time I thought I just got burned out on running.
After that I slowly got up to 190 lbs in 2008-2009, went on TRT and dropped to 150 lbs. Basically a lot more active, didn't really pay attention to diet.
Went off TRT, gained from 150> 168.
Currently back on TRT, lost 168>~155 lbs, then added metformin + TRT +avoid excessive carbs + more exercise and went to 141 lbs. (I was also taking LEF ultra prostate forumla, which raised my SHBG from 45>66 and lowered FT, E2, DHT.) But it did lower my PSA from 4.2>3.4 which was my main objective. And diet + metformin lowered my A1C from 5.8% > 5.2%.
Recently I stopped metformin, stopped the LEF prostate supplement. Wanted to see if I can maintain BG levels, keep dropping weight, keep a stable PSA level, raise FT/E2/DHT back to more normal levels, return SHBG back to the 40s.
I still eat quite a bit, our anniversary was on the 13th, went to a Korean all you can eat BBQ, ate a ton of grilled beef/chicken/pork/shrimp. It has little affect on BG since it was mostly all protein and only a limited about of kimchi.
I do think we have body set points where our bodies want to maintain a certain weight, like for me two areas I tend to set at are either 140 or 160 lbs.
Right now my main exercise is running, soon to be biking, and I don't ever want to get back to over 146, as it isn't easy to lose at my age. Also, skin isn't as elastic as it once was.
Of course, now I am 66 and losing weight, doing a lot of exercise isn't quite as easy as it was.
