You may not recognize Duff Goldman these days...In fact, he barely even recognizes himself!

The former Ace of Cakes star took to Instagram to share a side-by-side photo of his three-month weight loss, which he's chalking up to eating clean and working out more.

"Wow. It's been three months and I feel like these are photos of two different people," he captioned the photo, which sparked hundreds of comments.

Several fans asked how the Food Network star went about dropping the weight to which he responded "the old school way" of "eating clean, riding my bike and lifting weights."

Though this is the first time we've seen a side-by-side photo of his transformation, Goldman has been sharing his hard work with his fans on Instagram.

For example, he shared a mirror selfie, writing, "That feeling when you lose so much weight you drop a shirt size so all your friends send you new t shirts. Thanks @therealikes!"

He also shared a photo this weekend during his strip to Israel, noting how he's still managed to find time for his work outs.

"How to kill jet lag...wake up at 4 am, enjoy the local plant life while watching the sun come up over the Golan Heights, then hit the weights," he wrote. "My brother Willie did it all with me against his wishes, but I can be pretty convincing. This my Dwayne @therock Johnson impersonation."

Even on the Fourth of July—while the rest of us were eating hot dogs and drinking beer—Goldman shared a photo of two bun-less hamburger patties with pickles and grilled zucchini.

Meanwhile, Goldman joins a long list of celebrities who have dropped a ton of weight over the years. Check out their transformations below:
