The docs and the criticizers think they can pester people into losing weight. They really believe people can get healthy by denying themselves what they enjoy. Good luck with that!

Why don't you get yourself a bicycle (maybe an Electra Townie)
or join a hiking club
or a get a swim membership
or take up dancing
or start a garden

and see if you can't lose weight by having fun? Whatever you choose, it should be something you like to do.

I visualize the criticizers regarding one another with wild eyes. "Fun? Fun!" they cry. "We weren't put here to have Fun!"
