Nice work getting back down to where you feel comfortable.
I'm 50, 5'10", and dropped 160 lb back in 2016 with low-carb eating, lifting, and hiking. Kept it off until perimenopause started late last year and added almost 20 lb even though nothing else changed. HRT with an estradiol patch plus low-dose test-c fixed most symptoms but not the scale. Went from around 140 up to 157-162 and nothing I used to do would move it. After five and a half weeks on reta at 1 mg a week split into two shots I'm down 18.6 lb. Strength is fine, same maxes on bench, squat and deadlift, but the big Saturday hikes are tougher to bounce back from so I've cut them back. Easy bike rides fill the other days. Resting heart rate and HRV barely moved. Sleep is still only six or seven hours and the 4 a.m. wake-ups continue.
