Melissa Joan Hart dropped 20 pounds by cutting two things in her 'longevity journey'

"I just wanted to feel better. It had nothing to do with losing weight," Hart, 49, said at Aerosmith frontman Steven Tyler's Grammy viewing party on Feb. 1 in Los Angeles. 

"I really didn't think I could lose weight anymore, being in midlife and perimenopause," she added.

Hart said her main focus was on improving how she felt, and it has worked.

"I actually feel stronger and better than I have in a really long time," she said.

Hart said it began by working out more intensely and paying closer attention to her lifestyle. In the process, she discovered intermittent fasting and decided to eliminate sugar and alcohol.

"I just don't even enjoy drinking. So why bother?" Hart said. "So I cut these things out of my life, and I started to feel better. And in doing that, I lost a lot of weight and kind of feel great."

Hart also shared that staying hydrated has been a challenge for her over the years, joking that her husband, musician Mark Wilkerson, notices her dislike for drinking water.

"My husband says when I drink a glass of water, I make a face like it's the most disgusting thing on earth," she said. "I'm sipping on it, like, 'Eww.'"

Instead, the mom of three said she often reaches for club soda with lime or tea. "I'll do hot tea, cold tea, green tea, peppermint tea - any kind of tea," she said.

Last year, Russell Crowe said cutting back on alcohol played a major role in his 57-pound transformation, and "Queer Eye" star Jonathan Van Ness has also spoken out about cutting down on booze and focusing on overall health.

Country singer Jelly Roll has credited long-term wellness and mental health support for his dramatic weight loss, while Matt Damon recently said cutting certain foods, including gluten, helped him slim down for film roles.
