The power to
have an extraordinarily fast metabolism. Not to be confused with Metabolism Acceleration.
The user has an accelerated metabolism, rendering them resistant to weight gain, illness, injury, and accelerating their healing speed. It also makes it difficult for users to become drunk, unless they drink a very large amount or a specially made one.
May need to eat large amounts of food to maintain their energy unless they have Self-Sustenance.
May age more rapidly than usual due to the speed of the metabolism causing telomeres shorten faster.
Food may not suffice because the user's body digests faster than the food can settle, leading to starvation.
Gluttony Inducement and Empowerment may take part as a side-effect.
