The keto diet is 70% calories from fat, 20% from protein (not high at all), only 10% carbohydrates. Fat is not broken down to glucose, they become free fatty acids and ketone bodies, Once the patient switches to using ketones as the energy source, cancer cells cannot use that pathway. Further more insulin spikes are mitigated and insulin is known to aid growth of cancer cells.
