If you undergo ketosis your humoural triglycerides will be lysed.

Other people have written much on undergoing ketosis for weight loss, if you're interested; beware though that much of their weight loss comes from loss of glycogen and water stores. Keeping yourself hydrated mitigates the latter, but liver glycogen stores will be depleted. Absent readily available glycogen, your body will break down humoural trigylcerides as it is your only remaining source of energy; glycogen stored in your muscles is left untouched lest you exercise extreme physical exertion. I now speculate, but at this point your body has become accustomed to using fats as its main energy source. If you enter into any sort of fasted state, be it through a caloric deficit, intermittent fasting, sleeping, etcetera, your body will lipolyse adipose cells for energy; this must happen or you will die - whatever prevented this previously will have been circumvented. Actually, if verily your body is so stubborn it won't touch your adipose tissue, first you'd lose your skeletal muscle - then you'd die.

These are the physiological properties - if they don't apply to you, then whatever genetic mutation causes your body's nonconformity is unknown and I'd venture to guess has other effects as well.

If anyone tries this, pay attention to how fruity your urine/breath smells. If it becomes an overpowering scent, your blood pH may be too high. Either stop or take measures to rebalance your pH.
