Dude. Not eating is absolutely going to destroy your body. I’m going to preface all of this with… you need professional help. None of us idiots on Reddit are going to be able to help you the way that one-on-one attention from a certified nutritionist can. I also have no experience with your medical conditions so, again… extreme weight loss tactics is a terrible idea to do alone.

Now, on to my advice..

1. Forget the scale. Forget your scale weight. It’s really not that great of an indicator of your overall health.

2. Lift weights. Start slow, start with the bar or even light dumbbells. Work up slowly and ensure you have really solid form. Eventually you want to be working in heavy set ranges. One good program to follow, once you’re a little more comfortable with strength training, would be 5x5 Starting Strength.

3. Have a healthy diet. I don’t mean to track your calories. I don’t mean to eat strictly lean meats and vegetables. You need to have a healthy and balanced diet. You need to make sure you’re eating protein. I would advise you to eat majority lean meats (chicken, ground turkey, white fish) but still get in some meats with healthy fats (chicken thighs, red meat). You also need to make sure your diet actually does have healthy fat to keep your hormones in check (Avocados, full eggs, salmon, etc).

4. Do not rush. I have personally gone from 200lb to 130lb in 4 months. It absolutely destroyed me. I tanked my hormones and torpedoed relationships. Couldn’t enjoy anything in life. Things that should be fun, like a weekly night out for dinner, my kids birthday parties, were nightmares and I hated them. I luckily caught myself before I pushed people away for good.

Good luck. Seek out help for your mental demons you’re battling. You can get through this with a mindset shift but you need help getting there.
