Al Roker Lost 100 Pounds and Here's the Simple Habit That's Kept It Off for Over 20 Years

The weatherman lost more than 100 pounds and continues to maintain his weight loss through healthy lifestyle habits.

If you're looking for motivation and inspiration for weight loss—and keeping it off long-term—Al Roker checks all of the boxes. The newsman once weighed 340 pounds. After many unsuccessful attempts at losing weight, Roker had gastric bypass surgery in 2002, which helped him drop down to 190 pounds. Through major lifestyle changes, Roker has managed to keep the weight off like a total pro.

We took a closer look at his journey to learn exactly how he lost that much weight and kept it off for over 20 years.

He Had Gastric Bypass Surgery

Roker opted for gastric bypass surgery after many years of diets that just weren't working for him. Gastric bypass surgery is considered to be a minimally invasive procedure that supports long-term weight loss. It essentially "shrinks" the stomach, helping patients eat less.

When speaking of his healthy walking habit to EatingWell, Roker said, "It started out as a Facebook page. I was just walking and sharing the journey, and people started responding. And so the folks at Today said, 'Do you mind if we turn this into a thing?' And I said, sure, why not? Since then, we've got a little under a million people on our subscription newsletter, and since that grew, Today said, 'Well, why not an app?'"

Roker consistently motivates himself to make healthy choices, including taking every opportunity he can get to up his daily step count.

"Instead of taking a cab or an Uber, I'll walk up to one of the avenues and grab a bus. Now I've added five or six blocks going to get the bus, and then after I get off the bus, another five or six blocks walking home," he told EatingWell.
