Individuals aged 5 to 100 can practice 12-hour time-restricted eating without significant adverse side effects, except for those with type 1 diabetes.

“No, time-restricted eating is a very loose and broad term. So that means even if somebody...as I said, only 10% of adults eat for 12 hours or less. So that means if somebody was eating for 16, 17 hours, and even if they're pregnant or breastfeeding, they can come down to, say, 14 hours or 12 hours of eating, 13 hours of eating. And if they continue with that routine, they may still see some benefit.”

“And 12 hours' time-restricted eating, as I said, maybe safe for most of us, except a type 1 diabetic, unless they have a continuous glucose monitor and they have some calories handy if they become hypoglycemic.”
