Calorie Control is a hidden technique of the Akimichi clan and the foundation of all their techniques. The ability allows one to freely convert calories accumulated in the body into chakra and direct it toward enlarging parts of the body or the entire body as a whole. Inexperienced clan members are forced to use the Three Colored Pills to trigger this process, but the pills have a serious drawback: they burn a huge amount of calories in the body at once, which is why the consequences can be dangerous. When the technique is fully mastered, the pills are no longer needed, and the user themselves decides exactly how much body weight to convert into chakra at any given moment.
It is precisely because of this technique that the Akimichi clan is renowned for its appetite: the more calories stored, the more chakra can be used in battle.
