Gil Gerard was a childhood hero of mine, he played Captain Buck Rogers in the american tv series during the early eighties. He always struck me as the kind of guy that might struggle with his weight in later years.
Having just bought the DVD of the original series I did a bit of digging around on wikipedia and then youtube. It turns out he did have a weight problem. The following are links to videos that show his amazing return from morbidly obese to amazing for age looking.
I was truly shocked at the result, this guy must be so pleased now.
