Military diet 🙅🏻‍♀️

I’m starting the military diet & I’m just so excited and had to tell someone I’m weighing at 288.6 ❎ I’ve gained 50 pounds in 8 months 🤦🏻‍♀️ I have PCOS & just confirmed Fatty Liver! 😓 So there is no doubt about it I HAVE TO LOSE THIS WEIGHT! 🏋🏻‍♀️ 2018 please give me some magic here ✨ I tried to do 15 sit ups today I only got 5 down 👎🏻 1 it hurt on the carpet.... 2 I’m so out of shape! But I did stay in a plank for 25 seconds hard, and very proud of myself!!!! Any advice ? Helpful tips? Something ?
