PHOENIX, Arizona – 

27-year-old Martin O’Shea lost his parents when he was very young, and grew up in foster care. This, he says, lead to a lifetime of overeating, to the point that on his 24th birthday, he weighed nearly 550 pounds.

“I knew I needed to do something, or I was going to die,” said O’Shea.

Against the better judgement and direction of his doctors, O’Shea said he took to the internet to find remedies for quick weight loss, and tried several over a 2-year period.

“I did Atkins. Paleo. I was a vegetarian. I was exercising as much as I could, and nothing worked,” said O’Shea. “Then I discovered the Blue Bonnet diet.”

O’Shea said he began eating nothing but sticks of butter, sometimes eating as many as 12 or 13 a day, and drinking large gallons of whole milk.

“It worked unbelievably, and here I am, only 12 short months later. I’ve had skin removal surgery and I started being able to go to the gym to tone up, but I’ve lost 390 pounds on the BB diet. All I eat is butter, still. It works amazingly.”

O’Shea has said that he often has fits of vomiting and has to wear a diaper thanks to “loose bowels,” but it’s all worth it to look and feel like “a human being” again.
