I don’t think they are particularly accurate either and I know self reported calorie counts aren’t accurate either.

The important thing here is that a 1200 calorie diet for someone that big is an extreme outlier and I’d like to know what the actual protocol was.

If there wasn’t a lot of consideration about actual composition of diet or if this was a longer term protocol I’d be extra leery of it.

You can be healthy with a zero calorie diet if done correctly and for the proper time period, but you should be consulting an expert if you do.

And for anecdata I’m 6’0, 215 and 45. 1700 calories is a crash diet for me.

Yeah, I don't weigh my food, so I am just making educated guesses. The only time I knew for certain how much I was eating was when I ate about 0 calories for an entire month - due to advanced gallbladder disease and a hilarious series of diagnostic missteps. I lost 20 pounds. Gained it all back almost immediately after my surgery.
