This ability grants members of the Akimichi clan free control of their body's calories — which they convert into chakra in order to perform their techniques. The Akimichi developed the Three Coloured Pills for easier use of this technique, however, the use of these pills carry great risks. On the contrary, these effects are not seen when the user performs the technique without the assistance of the pills. At the highest level of the technique, the user converts calories into chakra and releases the chakra in the shape of two large butterfly wings. In this form, the user can use some of their clan's high-level techniques, such as the Butterfly Bullet Bombing technique several times without experiencing fatigue or other adverse effects. The user still experiences weight loss but it isn't nearly as severe as when the pills are used.
