Ryan Seacrest sparked concern from fans after sharing his latest Instagram post.

The 50-year-old host and producer, known for his ‘golden boy’ image, which faced some challenges in May, took to Instagram on Monday to share a series of photos showing snippets of his recent life.

Several of his 6.5 million followers quickly remarked on Seacrest’s noticeably slimmer physique as he posted a full-body shot dressed in a khaki monochrome outfit.

He also posted close-up images of his face, with his grizzled beard thinly veiling his bony jawline.

‘He looks frail to me. I hope he’s doing ok!’ one worried fan observed, collecting over 500 likes.

‘Ryan, you’re getting too skinny!’ another said, adding a smiley face and red heart emoji.

One social media user warned, ‘Ryan, I adore you, but… the BIG but…. you are looking too thin. Sometimes being thin can age a person.’

Another person compared him to another celebrity known for his thin stature, adding to the thread: ‘Damn I thought this was Marc Anthony for a sec.’ 

‘Wow Ryan is looking very thin,’ someone else pointed out plainly.

‘What is going on here?’ a fan demanded to know, adding, ‘Something looks off.’

There were also people in the comments who supported Seacrest and slammed his critics.

‘I think it’s impolite to tell someone they are too thin. I hear this frequently and can’t help it due to the medication I’m on. Stay positive and supportive, everyone,’ a fan wrote.

Another angrily clapped back, ‘IT IS NOT OK TO COMMENT ON SOMEONES BODY. Period. Just because he is a man/celebrity. THIS IS HIS PERSONAL ACCOUNT. 

‘He is a real human who has feelings and ages and CHANGES. Your concern for him is laced in judgment and is just plain rude. … Would you say these things to his face? Then don’t say them here.’

A source told Page Six of Ryan’s slimmed down look, ‘Ryan has recently been doing a new workout routine — working out with a new trainer, Dodd Romero, combined with Pilates and yoga for the first time. That’s created a visible change.’

The insider additionally noted, ‘He’s also been enjoying vacation time this summer and eating lots of pasta.’
