Al Roker Reveals What He Did To Lose 45 Lbs. In A Few Months

Al Roker is opening up about his workout routine and weight loss journey.

The "Today" weatherman shared how he lost 45 lbs. in the last few months and that all he indulged in were some light exercise and a successful low-carb diet. Roker, 67, told Today on Monday that a few changes to his diet and focusing on exercise including doing the show's walking challenge, helped him lose weight.

"Exercise, and not extreme exercise — we're doing that 30-day walking challenge — that improves, I think, your mental health," he said. "Combined with a low-carb diet, I've lost about 45 lbs. in the last several months. I do about 100 grams of carbs a day and I walk," Roker added.

After discussing his healthy lifestyle strategies Monday, Roker also revealed what gives him a little extra motivation. “I’m the oldest person here. I’m trying to last a little longer,” he quipped.

Roker has been regularly sharing his workout regimes with his followers on Instagram.

Roker began talking about his health and weight loss after undergoing gastric bypass surgery in 2001, after which he lost more than 100 lbs., according to People.

In March, he celebrated two decades since the procedure with a heartfelt post on Instagram, along with a picture of him holding a pair of jeans he wore on his way to the surgery. "Hard to believe it was 20 years ago today, I wore these size 54 Levi jeans to my #gastricbypass at 340 lbs. and here I am today," Roker wrote on Instagram. He shared the same image on Twitter, too.

"It's still a struggle but I'm never going back. I have setbacks and struggle every day, but I never forget how far I've come," he shared.

Recently, in May, Roker participated in the Brooklyn Half Marathon. As soon as he crossed the finish line, he was presented with a medal by his wife, Deborah Roberts. “It isn’t setting any land speed records, but it was faster than any of my training walks. There is a sense of accomplishment. It’s like, ‘Wow, this is something 22,000 people did. Not everybody can do it.’ And you do feel like, ‘Oh, OK, I did that!’” he told Today at the time.
