The human body is badly designed. Or I should say, it was well designed a million years ago, when fat was needed.
It hasn't been needed for a very long time, but the body insists on conserving it
especially when you try to crack the single digits
it'll chew your muscle, slowing your metabolism, even though there's no health advantage - just the opposite
I can sympathize with non-naturals because they're basically forcing the body to stop being idiotic
