Hawaii '68? Lost weight? Got a tan?
Uh, I think you mean 1973. His weight was going up before Aloha so he lost a lot of weight. He got a tan then, also (one that was slightly over the top if I'm allowed to say that LOL).
Before his '68 Comeback special he was still skinny.
As for you, I don't know if health questions should be answered, many forums have a bit of a rule against them. But at the risk of getting into trouble, reduce your calories *and* exercise enough to create a reasonable calorie deficit. If you reduce your current calorie intake by 500 calories, then you will lose a pound of fat in 7 days. If you then burn more off with exercise then your deficit and weight loss will be greater. Add it up. Don't do what I did. I lost heaps too rapidly and am now stuck with lots of loose skin that I cannot get rid of without surgery.
So don't count on a perfect body by this Summer at all. I'm sorry, but I know the reality of it all too well to let you fall victim to any weight loss lies. Please take care with this ... my weight loss did not liberate me at all. In fact it's put me in a very large trap that I will probably never get out of until I am swimming in cash.
