Tom Selleck Is ‘Virtually Obese’ at Nearly 350 Lbs: ‘His Whole Body Is Falling Apart’

Tom Selleck has been battling the bulge for some time — and now sources exclusively tell Closer he's been eating comfort food to make up for the termination of his beloved show Blue Bloods.

Sources and medical experts tell Closer 6-foot-4 Tom is grinding the scales at 350 pounds — a 150-pound gain from his 1980s heyday on Magnum, P.I.

"Tom was a strapping 200 pounds when he was acting on the show, but now he's virtually obese," says an insider.

And Dr. Gabe Mirkin, who has not treated Tom, tells Closer: "I'd guess he weighs 350 pounds now. He has abdominal obesity, which is really bad — he gained the weight in his belly!"

As recent photos show, 79-year-old Tom sported a gut while out and about recently in Thousand Oaks, California, and appeared to have difficulty getting in and out of his Dodge Ram truck.

"He's bigger than before and it's a shame to see him this way, so heavy and struggling to squeeze behind the wheel of his car," notes an insider.

Sources say it was a sad day for Tom and fans to see Blue Bloods get the boot after its 14th season wrapped in June.

"It breaks his heart the show's over," says a source. "These people were family to him, and they went out for lots of fancy meals toward the end. He's been continuing that trend, judging by the looks of him!"

Sources say that although Tom vows to hit the gym, loved ones fear he’s putting his health at risk with his diet.

"His whole body is falling apart by the looks of him," says an insider. "He needs to shed pounds, anyone can see that, but it's not going to be easy. Clearly, this forced retirement hasn't done him much good!"

Dr. Mirkin warns massive abdominal obesity carries a long list of potential health risks and is "associated with excessive fat in the liver that causes insulin resistance, that causes diabetes, that increases risk for heart attacks and strokes.

"He must get the fat out of his liver immediately, if not sooner! I am so worried about him that if I were his physician, I would recommend gastric bypass surgery if there were no health factors to make this too dangerous. An alternative to gastric bypass surgery are the new weight loss drugs, but they also have significant potentially serious side effects. He needs a very kind and interested physician who will talk to him about his options!"
