Try exercise.
Does chess help you lose fat?

Playing Blitz using very heavily weighted pieces (at least 1 kilogram each) might help you to lose weight.
It's called "pumping Pawns".

I wish the OP would come back. I think he could be a fairly entertaining troll if he applied himself...

once I had to move my queen ALL THE WAY ACROSS THE BOARD!! I probably lost at least 100 calories with that move.

Yep, and never promote a pawn - too much work involved...

Come to think of it - my Queen is fairly fat now, chewing up all those pieces over the years - now I only move it one square at a time . . . . . . . any more than that and she just topples over. . . . . . makes it hard to win a game.

I make sure my King gets plenty of exercise running laps around the board. Keeps him from getting fat and lazy.
I am very fat and I want to lose a lot of weight. Will studying chess help me, or am I better off with checkers, Monopoly, Uno, and the occasional euchre tournament?
