At the risk of sounding like a proselytizing bastard, but doing it out of genuine concern and sharing what little knowledge of nutrition has personally worked for me: Have you tried a low carb diet like keto?. It's the only thing that's been able to help me with fast, consistent results and the modest willpower I can dedicate to the problem. I'm sorry in case you weren't looking for advice.

I lost 70 pounds (nearly a third of my weight) through just restricting my intake to two tiny meals a day. It sucked really hard at first (I was in what felt like physical discomfort and didn't defecate for a week when I started), but it worked and I've kept it off. It takes time (for me the better part of a year), and making a decision and the willpower to stick with it no matter how much it sucks (as long as you know it's safe).

My hunger is still all in my head to this day. I'm sure the challenge of not overeating will last the rest of my life, but the tradeoff of weighing less is worth it.

If you want to read about how far the mind can take you, read David Goggin's book, Can't Hurt Me.

Really sorry to hear about your struggle.

At that weight, you are very likely already regularly connected to your doctor, and have probably tried many things, and anything anyone says here will probably sound rude, ill-informed, or trite.

Regardless, you can get through this. Day by day. Good luck.

It (Ozempic) has already been approved for treatment of diabetes 2 for a couple of years. Maybe you could qualify. The trials mentioned is basically just a phase 3 trial of the product specifically for weightloss.

At 300kg you probably cant even walk, meaning someone is actively harming you by bringing you food.

Are you serious? Is that possible? No offense.
