(WXYZ) - More employers are keeping tabs on workers' health and it could mean they're also watching your waistline.
A new survey found many companies are charging workers extra for health insurance if they are overweight or smoke.
The survey was conducted by Towers Watson and National Business Group on Health.
It found 40 percent of companies will use surcharges for workers in 2014 based on their health. That number has nearly doubled from 2011.
If employees don't complete health goals, some companies will force workers to pay higher insurance premiums or deductibles if they smoke or are overweight.
Many companies also offer considerable insurance discounts for those who don't smoke and have a healthier weight.
Experts predict the number of companies who penalize smokers or overweight workers will rise to two-thirds by 2015.
