The TV star has changed her lifestyle with a few additional healthy habits and has never looked or felt better.
In a discussion about yo-yo dieting earlier in the year, though, the mom-of-three made a relatable revelation about her own experience with the specific diet, and admitted that it just doesn't work.

"We know that yo-yo dieting doesn't work. It doesn't. I've tried to but I've always gained the weight," she said.
Jenna's co-host Hoda Kotb agreed, saying: "You think whenever you yo-yo diet you starve and then you eat a cracker and stand on the scale and you gain weight. Any added calorie tips it."
"If I start to think about it I lose all consciousness and then I'm eating Teddy Grahams," Jenna concluded.

After being praised by Hoda, who mentioned that a number of viewers had written in to compliment Jenna's appearance, the TV star replied: "I will say I think I have figured out what works for me. And I think the hard thing is I think we expect things to happen overnight. This has actually been over six months."

When quizzed on what she's been doing, the mom-of-three replied: "The difference is I wake up before the show and I work out.
