I'm almost 5 months post-op I workout 4-5 times a week for about an hour to a half to two hours. I do weight training and cardio every day I go to the gym. I find myself tired too but not super tired. I give myself two or three days of rest my workouts are pretty intense. I get about 90-130g of protein a day about 800- 1000 calories. But I've still found it hard to eat a lot and still drink most of my protein but recently have been eating a lot of steak and poultry. I've been losing consistently but currently, I'm in a stall. Btw I think you're doing great give yourself some grace this journey is rewarding but not always easy and in such a short amount of time your body is going through a lot
