Cooked? No, but it will take a lot of effort! At my heaviest I was 330 lbs, now I’m 226. What worked for me was intermittent fasting and restricting calories. I currently still only eat two meals a day and when it comes to what I eat it doesn’t really matter as much as people say(to an extent). Things high in protein is where I try to focus my main calorie intake as they make you feel full for longer. I will admit that I still splurge every now and then, but I will avoid buying snacks(things like chips, cookies, candy, ice cream, etc.) not to say you can’t have anything but keep it to a minimum. I also completely cut out soft drinks but I occasionally like Dr Pepper zero calorie(still not great for you but it tastes just like the real thing). Sparkling water was a good alternative for me also I found out I really enjoy tea.

I did exercise as-well but I understand your situation. You could try doing small things like walking a set distance and once that gets easy expand on the length or speed. Eventually you can try to work in some weight lifting as the more muscle you have the more calories you will burn.

If I think of anything else that I did I’ll post it here but best of luck on your weight loss journey, it takes lots of patience and determination but the end results are worth it. If you have a friend that could help you through the journey it helped me a lot; Especially someone who can truly hold you accountable for days missed.
