From a genetic perspective, certain people are less metabolically flexible because they have genetic variations (e.g., insufficient production of specific enzymes) that make it more difficult for them to adapt to the ketogenic diet. In contrast, those who are quick keto-adapters may be gifted with genes that enhance their ability to switch between fuel sources more efficiently.
