In reply to Laurie.

Starvation mode is something that happens when your body is consistently starved of nutrients. For example, when you restrict your calories drastically and eat under 1200 or even 1000 calories a day, that'll start to take a toll on your body.

Intermittent fasting doesn't restrict calories, it simply dictates when you eat them. Fasting for a few hours is not going to send your body into starvation or panic. Your body will adapt to a new feeding schedule very quickly.

Hope that helped!
