Feels unhealthy after losing weight
2 years ago I used to be 90 kgs and before that my weight used to fluctuate from 80, 85 , 90 , 95. Finally I met a proper endocrinologist and treated my hypothyroidism and pcod, got a better diet, started exercising and now I'm 66 kgs . My blood work is all good (I get tested every three months), I exercise regularly (both cardio and strength) , I'm still working on my protein intake but I'm still eating more protein than I did when I was heavier. So why, I wanna ask, why the hell do I feel so much more tired and weak?? I feel like I was more energised and strong when I was 90kgs and now a backpack on my shoulders on a little hike almost kills me. Is it because I'm ageing? But how can one age so much in 2 years lol
