Here's why Jenna Bush Hager and Hoda Kotb weighed themselves on live TV

Worried about your weight when you appear on-screen? Well, journalists Jenna Bush Hager and Hoda Kotb took a bold step by stepping on a weighing scale in front of millions of viewers on Monday while experimenting with intermittent fasting.

The 'TODAY' with Hoda & Jenna hosts said they were not doing intermittent fasting for shedding kilos of weight, but "to be healthy". As some forms of intermittent fasting have been proven beneficial for weight loss, the two ladies decided to check how much they weigh.

While Hoda weighed 158 pounds (approx. 71.6 kilograms), Jenna, who was blessed with her third child in August, weighed 171 pounds (approx. 77.5 kilograms), NBC's TODAY reported.

"You all know what is plugged into my Fitbit for real? 130 pounds. I weigh 40 more pounds than I tell everybody I do!" Jenna said before turning to Hoda saying, "You just had a baby."

After their experience, the two journalists sat down with NBC News Medical Contributor Dr. Natalie Azar to learn more about fasting successfully.

The doctor said that intermittent fasting can be beneficial for those who have obesity or are diagnosed with Type 2 diabetes, which can impact a person's health in the long-run.

"I think more in its infancy is the stuff about longevity and Alzheimer's, and, you know, maybe it has a role in treating or managing chronic disease and cancer. There's no large trials of any of those things, but mechanistically it's a very interesting, hot topic right now," she was quoted as saying.

"There is no rule because there are so many different ways to approach this. Conceptually, it's not a diet. It's a way of eating. It's when you are eating as opposed to what you're eating," Azar added.
