JuvenescenceFasting, low-carb, high-fat diets like keto, and drinking ketone esters can all prompt ketones to circulate in a person's blood. Ketone ester drinks don't require the liver to convert fat into ketones, which is what happens with fasting and the keto diet. "If you were wanting to lose weight, you want to be burning your own fat and turning it into ketones," Stubbs said. Ketone drinks don't do that. But she also says that any eventual geriatric recommendation for ketone esters isn't likely to be one-size-fits-all.
