Is calories in, calories out truly accurate?

If CICO is so complicated then someone explain to me how I've lost 79 lbs in a year and only 5 lbs of lean body mass? I eat carbs, I eat fat, I eat protein, I eat fast food, I eat ice cream, I eat donuts, I don't eat Twinkies though but I do occasionally eat McD's. I try to meet my macros but I'm off more often then not.

What is so complicated because I am not a special snowflake and my body does not defy the law of physics?

You obviously have a comprehension problem if you have to ask this. No good would come from trying to explain it again.
