Ryan Seacrest’s Thin and Unhealthy Appearance Sparks Health Concerns: ‘It’s Worrisome,’ Says Source

Ryan Seacrest’s appearance has fans fearing for his health — and sources say friends are equally concerned that something’s amiss because the media mogul seems to eat very healthy.

The Wheel of Fortune host, 50, posted a series of photos on Instagram — including pics of him wearing ankle weights and holding a pan of grub.

“He loves to tell people how much he eats and what he eats and that he’s indulging in pasta and carbs, and that he’s absolutely fine — but no one is buying that,” an insider explains.

The insider says, “If he’s eating plates of food, why is he skin and bones? He can’t have a magical metabolism. Either he’s not eating — or if he is eating, then why isn’t he gaining weight? It’s worrisome that there may be a deeper issue with his health.”

But a pal insists Ryan has no medical issues and is “totally fine,” adding he’s been working with a new trainer and doing pilates and yoga.

However, according to the insider, the hustling Hollywood hotshot is running himself ragged as emcee of Wheel, American Idol, his weekday morning radio show and weekly American Top 40 countdown program.

Dr. Gabe Mirkin, who has not treated Ryan, tells the National Enquirer, “He may have a condition that is causing him to lose weight. If he were exercising vigorously and on a diet, he should be losing mostly fat. On the other hand, he has lost a very significant amount of muscle. He could be willfully restricting calories severely enough to do this — but this is very unlikely.”

Mirkin says a healthy weight for Ryan would be around 160 pounds — but notes that the star appears to be just 140.

The doctor warns, “Severe loss of muscle is often a sign of disease.”
