Hey, just wanna chime in with my experience, 6 months on HRT. I started at 183cm/61kg and HRT made it a lot easier for me to eat regularly, I didn’t eat breakfast most days before. Now, I’m eating a hearty breakfast and lots of snacks inbetween (almost didn’t snack at all before) and I LOST weight, last I checked was a month ago or so at 59kg. I figure most of that was muscle though, my thighs grew a bit. So eat away, I’d say. I’m eating a good 25% more than before HRT and am barely keeping my weight.
I always keep a supply of nuts, mainly cashews and salted peanuts, on my desk to snack on during the day. Healthy fats!
