Valerie Bertinelli just shared that weight loss has been an unexpected side effect from giving up drinking last month.

On her TikTok account, Bertinelli posted a video walking and talking to the camera when she revealed her Dry January experiment, a popular movement where people give up drinking for the first month of the new year, had an unintended "side effect."

"So, here's a nice little side effect of Dry January," she said. "These jeans that I'm wearing were so tight a few months ago that I couldn't comfortably button them. Now, they're so loose it's time for me to go down a size."

She continued, "Yeah, I like that side effect."

VALERIE BERTINELLI SAYS NEW YEAR'S DAY 2023 IS THE ‘FIRST DAY OF THE REST' OF HER LIFE: 'I'M FREE'

Last month, the Food Network star announced she was participating in Dry January for two reasons.

"One, I want to try and cut down the cravings for my sugar. And I think alcohol exacerbates that," Bertinelli said in a social media video.

The second reason was to lower stress.

"I want to calm down the cortisol in my body that has been raging for the last five, six years. I've been in fight, flight, freeze, fawn mode. And I want to go into rest and digest," she shared. "I think cutting alcohol will help me do that."
