Jack Nicholson: Diet or Die!

FATSO Jack Nicholson has boozed and gobbled his way to a whale-sized 357 pounds — and is in such dire medical straits, pals and docs fear he won’t live to see his 80th birthday early next year!

A longtime friend describes the 5-foot-9 movie “Joker” as a “ticking time bomb,” saying his “weight has exploded! He’s a heart attack waiting to happen.

“He has a long history of yo-yoing weight and very unhealthy habits! Jack was a cocaine abuser for many, many years and a heavy smoker.

“He played golf occasionally but otherwise he’s been very sedentary in recent years.

“He also had anger issues — and very high blood pressure. If he doesn’t change, he’ll be dead in six months!”

Health and fitness expert Dr. Gabe Mirkin says the Shining star “looks like he is already a diabetic and is at very high risk for suffering a heart attack!”

The author of The Healthy Heart Miracle also notes Jack’s body type allows for a dangerous buildup of fat.
