but my hypothesis for why that's the case which could be entirely [ __ ] and I'm just making it up but it that's what hypotheses are they're guesses is that it would have been evolutionarily dangerous if we could have metabolized cholesterol because in periods of fasting which we all did evolutionarily the last thing you want your body doing is going after cell membranes and hormones as a source of energy so I think it's actually a very deliberate design quote I use design in quotes to say hey no matter what your cholesterol and your hormones are off-limits during starvation and instead we evolved this other remarkable pathway of ketosis which takes an ample substrate of fats and goes down the path of metabolizing those and actually saving our muscle from the catabolic destruction that we would undergo if we couldn't undergo ketosis
