Eric Stonestreet is the latest celebrity to open up about using a GLP-1 weight loss drug.

On Thursday the 53-year-old Modern Family alum showed off his impressive weight-loss in a new Mounjaro campaign with his mother Jamey.

‘My mom Jamey and I are proud to share our success stories with Mounjaro. We hope to inspire others to talk to their doctors to get the treatment they need,’ he wrote in a joint Instagram post with the brand.

He said he used to think he was ‘fairly’ healthy aside from struggling to lose weight, but after he was diagnosed with diabetes in 2009, the actor said he was ashamed.

‘I was embarrᴀssed. I didn’t want to tell anybody. I knew my mom and dad were both type 2 diabetics and didn’t share it with them. If I was dating a person, I never shared that with them. I didn’t tell my two best friends for a long time,’ he revealed to People.

The diagnosis came right around the time he was cast as Cameron Tucker on Modern Family.

He recalled, ‘It was like this crazy happy moment cut with this diagnosis that I truthfully didn’t take very seriously.’

Eric opened up about how his doctor at the time neglected to provide any encouragement.

‘I had a doctor that sent me on my way with a couple pills and said, “Take care.” No inspiring moment of, “You need to seize the day and change this,” which I guess technically isn’t their responsibility, but I just didn’t do anything about it,’ he said.

He went on to say that he even hesitated to tell his now-fiancée Lindsay Schweitzer about his health early on in their relationship.

The Emmy-winning performer revealed: ‘I would hide my injectables and my pills from her. I didn’t want her to open the fridge and see something in there.’

Once he started seeing a team of doctors who stressed the gravity of his type 2 diabetes, he finally made a change.

Stonestreet thought of his dad, who suffered from ‘very painful’ diabetic neuropathy before his death.

Stonestreet said he used to think he was ‘fairly’ healthy aside from struggling to lose weight , but after he was diagnosed with diabetes in 2009, the actor said he was ashamed 

Eric explained about his late father, ‘He pᴀssed away from leukemia, but the thing that was the most painful for him was his diabetic neuropathy. And I just decided, well, I can’t go down that road.’ 

While making a change to improve his health, the TV star also considered the 13-year-old twin boys he raises with his fiancée.

‘They’re her kids but I’ve known them since 3 so they’re my kids as well,’ he said about taking on parenthood. ‘And just like every parent, I want to be around. So I just decided, I gotta stop this train from going that direction and reverse it a little bit as best I can.’

Stonestreet began taking weekly Mounjaro injections in May 2022 and has overhauled his health.

‘It’s a game changer,’ he said about his experience, adding, ‘It has just been incredible. It’s changed my lifestyle, changed my approach to eating, changed my approach to exercise.’

Stonestreet is known for playing Cameron Tucker on the hit ABC sitcom Modern Family

The show ran for 11 seasons on ABC from 2009 to 2020; seen in 2020

Due to his success with the medication, he felt inclined to make lifestyle tweaks to keep up his results.

‘I felt like, well, if I don’t do something along with it, I’m disappointing it. I’m letting it down. Here these people have invented this incredible thing that clearly does its part. Now I need to contribute my part,’ he reflected. 

‘It turns out that when you do that and make some really great choices, weight loss is also a byproduct of that,’ the actor noted.

Stonestreet continued: ‘I experienced a little weight loss. My mom, she lost a significant amount of weight in her experience with it, but I’m down quite a bit.’

Adding some more context, he shared: ‘I kind of was at the same weight for many years, but then in the last year when I started to really contribute more to it, I’ve dropped substantial amount of weight.’

Now, he says there’s ‘a pep in my step,’ which he notices during moments like when he’s walking through the airport with luggage. ‘I’m just lighter on my feet. It feels good. I mean, everyone’s experienced that. You lose a couple pounds and you feel better.’
