My company did that with a "wellness" program. The down side is that you have to submit to a long list of measurements that are entered into your personnel record as a starting point. No thanks. My employer doesn't need that information. The "payback" is a $75 annual reduction in the healthcare premium (currently running $300 every two weeks). Big deal. It's a fart in a hurricane.
I control my calories in a very narrow range daily. My weight stays +/- 0.5 lbs from day to day. I can drive it down by adding a fixed amount of exercise daily. I don't need government or employer "intervention" in my life.
Husband and I were watching our 8 and 5 year old grandsons playing the no score version of baseball. We got to talking how the boys didn’t know how to play ‘work-up’ or ‘500’. No bats allowed at school recess and no playing anything but parent organized sports after school.
Our son (about 25 years ago) never went hardly anywhere without a basketball to be shooting and dribbling. That is until we bought him an atari game system for Christmas. He quickly changed into a chubby little boy. And still fights weight gain. His dad and I have never been good examples either-sadly we eat too much for all the wrong reasons and watch way too much tv instead of exercising.
