Everyone goes through visibly noticeable changes as the years go by. Celebrities are no different, and many turn to cosmetic surgery to slow down the ticking hands of time. Understandably, being public figures whose looks have a hand in earning them an income, most stars do what it takes to maintain their youthful glow.

Until scientists cook up a fountain of youth, no one can escape the natural process of aging. Here is a list of celebrities who look quite different now after losing weight, battling substance abuse issues, or simply because age caught up with them.

Valerie Bertinelli – One Day At A Time

It’s been years since Valerie Bertinelli became a household by playing Barbara Cooper in “One Day At A Time.” Her marriage with Eddie Van Halen fizzled out, she packed on a few pounds, and she slimmed down again through the Jenny Craig method.

Once she was done with the show “Hot in Cleveland,” Bertinelli transitioned from acting to hosting after bagging two Food Network shows titled “Valerie’s Home Cooking” and “Kids Baking Championship.” The Delaware-born star, who has two Golden Globes under her belt, is still presenting both shows in 2021.
