Jillian Michaels on an Overnight Fasting Window: recommends

Jillian Michaels recommends a 12–16 hour overnight gap between dinner and breakfast, per her own site. She says this fasting window helps “lower insulin” and releases a small amount of ketones — without adopting a ketogenic diet.

Her stated reasoning is that the overnight gap delivers some of fasting’s metabolic benefits (lower insulin, modest ketone production) within a normal eating pattern, making it her moderate alternative to the extreme restriction she attributes to keto. She presents it as the least disruptive way to get a fasting effect.
