Do you mean that his heart attack 
occurred 20 years after starting and losing the weight,
No -- sorry for the confusion -- the heart attack happened when he was 
overweight.  It was while recovering from  his heart attack (20 years ago)  that he 
discovered the Stone Age diet.  He credits the diet with likely saving his 
life.  He is reflecting back upon his life in this book -- page 2:

"I know firsthand about the problem of being overweight, and I know firsthand 
about the laws of nature that we must follow to lose weight.  Twenty years 
ago, I was overweight..." 

He goes on to say that when he reached middle age, many of his friends had 
died of heart attacks but he was not motivated to lose weight until he himself 
had a heart attack. Following his Stone Age regime, he went from a fat (his 
word) 232 pounds at 6'1" to a lean 176.  His cholesterol dropped from 312 to 192 
and then to 132 at the time of writing the book.  Here's a direct quote from 
Pages 8 & 9: "In spite of having eaten a high red meat, high animal fat diet 
for 20 years my last cholesterol reading was 132.  To my surprise, entirely 
without any effort -- as if by magic, my weight kept falling at the rate of two to 
three pounds a week.  My weight is now at 176.  Effortlessly, for 20 years 
I've kept my weight normal."

Newbold explains that he previously never had any professional interest in 
weight problems other than his own and that after he lost weight and lowered his 
cholesterol -- that was good enough for him and he didn't feel the need to 
"struggle against the medical establishment to point out its errors."  

He goes on : "Now, 20 years later, I'm more interested in weight reduction 
and teaching physicians about my new way to lower weight and lower cholesterol. 
I've had scientific articles published about my cholesterol research in 
respected, mainstream, peer-reviewed, Medical-Index listed medical journals such as 
the International Journal for Vitamin and Nutrition Research and the Southern 
Medical Journal."
