Key Moments

Drink water first thing in the morning to suppress ghrelin and extend your fast easily

Drinking water in the morning stretches stomach receptors and suppresses ghrelin, the hunger hormone. Bulky vegetables have a similar effect -- they fill the stomach and activate stretch receptors to increase satiety with fewer calories.

"You drink water, it stretches out your stomach receptors, it suppresses ghrelin, your hunger hormone release, right? And you naturally feel more satiated."
