The researchers report on the impact of environmental interventions at several Dow Chemical Company worksites. They found that simple, low-cost interventions — for example, encouraging workers to take the stairs and making healthy options available in vending machines — helped to avoid employee weight gain.
Getting rid of junk food and encouraging people to just move a little more? Makes sense to me.
And, as I always say, just not gaining weight is half the battle of losing weight.
