So I have been on (around) a 1200 calorie diet for about 2 months now. I know its low, but I get a lot of protein and I have lost about 13 pounds so far. I want to exercise as well, I am just wondering how often. I have been doing 15 minutes a day on the stair stepper. I don't want to do too much but not too little. Is 5 days a week ok? I am 5'6 and 160 pounds currently. Any help would be appreciated. I just want to lose a decent amount by summer and no, I don't feel hungry or like I am starving. Thank you.
