Beyonce, Jay-Z and Gwen Stefani diet secret: Leptin

You may hear a new catch phrase floating around just in time for Christmas: Leptin. What is it and how do you get it? Marco Borges, trainer to Beyonce Knowles, Jay-Z and Gwen Stefani, breaks it down:

Leptin is a naturally occurring hormone that acts like appetite suppressant because it "suppresses the hunger hormone ‘ghrelin’ and brings about satiety for healthier partying," he says.

Eat slowly and wait 15 to 20 minutes after the first plate.

Eating the right foods can help release leptin, too. "Before that big holiday party, pop a handful of nuts," Marco advises. "They contain the right amount of protein and fat, which release the hormone leptin."

However, he warns: "Not all nuts are created equal."

Marco’s top 4 nut picks:

  1. Walnuts
  2. Almonds
  3. Pecans
  4. Cashews

    Cashews are a seed not a nut.

  • Yaya 4 years ago the culinary sense, a cashew is a "nut" but in the botanical sense the fruit of the cashew is a "seed;" so therein lies your confusion.
