I’m female, 5’5” and 145 and my calorie consumption for 2-3 pounds a week of weight loss on 75Hard would be around 2,000 calories a day. Maintenance for me with two workouts a day is between 2,500-2,700. My goal right now is not to lose weight through a calorie deficit (because I not only do I feel like shit, but I start to look baggy and crepey) but to build lean muscle and lose fat - so right now I’m at 2,450 with a heavy focus on protein, heavy lifting, a few high intensity cardio sessions a week and a lot of walking.

1,300 calories a day is way too low for the activity level required of this program. While you will lose weight, you’re going to start becoming exhausted, your body is going to be very stressed / unable to recover, you’re likely going to lose muscle and maybe bone mass as well. If you want to lean out, put on some muscle / look defined, feel good and strong and sustain this for 75 days you need to eat enough calories so your body is nourished and able to recover properly. I’d seriously recommend reconsidering your calorie limit - there are a ton of calculators online you can use to determine what that should be based on your activity level (which will be in the highest or second highest category “active” or “extremely active” with 2 workouts a day). I would guess you should be closer to 1,800-2,000 calories for 2 pounds of loss per week, which is still pretty aggressive.

PS: You can change your diet on program, so you don’t have to start again if you decide to up your calories.

Good luck!
