For you youngins, you should look up Jack LaLanne.
I am 48 and I kind of, sort of remember him. I also remember his back story which has more meaning to me now that I am going low carb and have given up sweet treats.
He was remarkable. Growing up he didn't like how hyper he was, aggressive. He set out to change it and noticed sugar was very harmful to him. Way before even the science in the 1970s that was subsequently suppressed he was anti-sugar.
Thanks Jack. I wish I'd had listened to you even earlier.
