/ck/ - Food & Cooking

So I've been on a diet for a month now because I'm a fat fuck and I don't fit in chairs anymore. At first I lost weight rapidly and now I'm down to about 260 lbs but allready I'm stuck.
I have to eat less than 800 kcal (!) a day to keep losing any weight at all when at my size 1500 should suffice. Is this my body adapting or the infamous "starvation mode" - people always say it doesn't exist or only accounts for a few 100k not a fucking 1000.

Anyways, has anyone on /ck/ encountered a similar problem? Is it even possible to make proper meals if you're down to <800 kcal a day anymore?
