d a, come to think of it, you're right. Jack Nicklaus did have the nickname "Fat Jack" when he first got started as a pro. While he did hit a lot of golf balls for 6-8 hours a day to get his swing down, it obviously did not do too much to help him lose the weight. I'm not sure what kind of regime he got on to lose the weight but he was looking pretty trim in the late 60's early 70's. I lived in North Palm Beach, FL during that time and Jack was a pretty visible celebrity. Plus his kids would play with the kids my girlfriend (later my wife) was taking care of 3 houses down from Jack and Barbara's. I remember his 3 sons (Jack Jr., Steve, and Gary) were very athletic and Jack starting playing basketball with them and their teammates as they got older.
