1. Insulin is real. Calories in / calories out people - 'eat less, move more' - grasp onto one truth but don't take insulin into account. 500 calories of sour cola bottles isn't the same as 500 calories of meat in that the sour cola bottles will spike your insulin. 2.

Look at Dr Sten Ekberg, or any oncologist for information about longer term fasting and insulin. Anecdata you can ignore: for me, a 48h fast drops about 1% of my body fat, originally there's a 2% drop but it'll come back up to -1% after a few days.
