Have a happy and healthy holiday! Dr. Steven Gundry, the expert behind transformations from stars like Kelly Clarkson and Usher, is sharing his top wellness tips with ET just in time for the 2026 holiday season.

Before you hit a holiday party, Gundry says a little prep can go a long way.

“Eat a handful of the right nuts beforehand to you’re not starving and tempted to eat things you wouldn’t normally have,” he advises.

Think: Hazelnuts, macadamia nuts, and walnuts. But proceed with caution when it comes to pistachio nuts before a long night out.

“Pistachios are a natural source of melatonin, so they might make you sleepy,” he notes.

Once you’re in party mode, hydration is key, especially if you’re enjoying celebratory cocktails.

“If you plan on drinking alcohol, have a big glass of water between each beverage, or aim to sip one drink throughout the event,” he says.

If alcoholic beverages aren’t on your menu, Gundry still has a festive fix. 

“Get a cocktail glass full of sparkling water, add a lime slice, and act like you are sipping on a gin and tonic. … Drinking sparkling water will also help fill you up,” The Gut-Brain Paradox author explains. 

When it’s time for dinner, load up on greens before diving into other dishes.

“Fill your plate with a majority of veggie sides and make the carb-rich sides and meat the minor part of your plate.”

After you’ve eaten, don’t just settle into a seat. Instead, take a lap around the party.

“Studies show that going for a quick walk after eating aids in digestion and supports maintaining a healthy weight,” Gundry shares. 

Of course, if you stray from the plan, The International Heart and Lung Institute and The Centers for Restorative Medicine founder recommends giving your body a little extra love at the end of the night.

“Overindulging on either food or alcohol can happen if the conversation is flowing and you’re having a good time, but before you go to bed, take chlorophyll and H2 water to help flush out the toxins.”
