Kate Geagan

Hydration Advisor

If you think you’ve seen Kate somewhere before, chances are you have. Kate is a nationally-recognized nutritionist, author and frequent guest on the Dr. Oz show. (Not to mention Access Hollywood LIVE, Martha Stewart Living Radio, Montel Williams AirAmerica, as well as dozens of NBC, ABC, FOX, Comcast and CBS affiliates.) Known as America’s Green Nutritionist™, she's an award winning dietitian and author of Go Green Get Lean: Trim Your Waistline with the Ultimate Low-Carbon Footprint Diet. In 2013 She was named one of the Top 10 RDs Making a Difference by Today's Dietitian Magazine.

What we love best about Kate is her knack for real advice we can use, no matter how busy our schedules. Kate knows the challenges of raising kids (she has two) and balancing a full work and travel schedule (she calls having Platinum Medallion status "a mixed blessing") so her approach to smart nutrition is served up in manageable bites, and always with a side of humor! Our favorite Kate-ism? When we asked for her most common hydration tip, Kate reminds us to "Eat your calories—Drink water." We couldn’t agree more…why waste precious calories on sugary drinks when your brain is happier and more energized when fueling up on water and real food.

Look for tips and nutrition advice by Kate in magazines like O, The Oprah Magazine, Rachel Ray Everyday, Time, Self, Better Homes & Gardens, Prevention, Men’s Fitness and Health Magazine—and of course we’ll keep posting Kate’s great tips and ideas on HydratED.
