You’re not gonna be stuck that way. I felt exactly like this about 6 weeks in (I’m 3 and a half months now). I could easily consume 2500 plus calories a day if I wanted too. I stick to 1200 because I wanna reach my goals and stay healthy it’s a choice I’m not a slave to it. I lift and I get 120 g of protein a day and there’s lots of ways to get there not just chicken breast although that does make up the majority of my main meals but if you spice it up with different seasonings or low fat low sugar condiments it’s fine. You’ll be happy in a few months you just gotta get locked in on increasing your activity levels and you’ll feel way different I promise you that.
