Workers at Mexican Oil Company will receive a health incentive of almost $300 a year if they meet certain body weight standards.
To qualify for the bonus, they must maintain a healthy weight.
For those who are overweight or obese, they can receive the bonus if they reduce their weight by 10% during the year.
Some applaud the policy as fair, because it rewards both individuals who maintain a healthy weight and those who are working towards achieving it.
But critics say the policy contradicts recommendations by many health experts who warned that a person's weight is influenced by genetic and environmental factors.
That means weight can be hard for individuals to control, which makes the bonus unfair.
Some experts say the policy is inconsistent with the science of what we know about body weight regulation.
These experts argue that focusing on weight is the wrong approach.
A more productive method of encouraging health among employees is to promote healthy behaviors.
For example, companies can give workers gym memberships, or encourage participation in lectures on healthy eating and living.
They can also reduce sweets and provide healthier snacks in the office and healthier meals at the company canteen.
Or they can give employees more time during their lunch break to exercise.
These are much better and much more productive ways for companies to move forward on their employees' wellbeing.
