When Is a Pound Not a Pound?

A new study challenges a longheld weight-loss belief, but we can still eat grilled pizza sometimes.

Just about the time Travel and Leisure magazine affirmed Providence as a foodie capital comes a medical study that questions some longheld beliefs about losing weight.

The study challenged the idea that 3,500 calories burned leads to one pound of weight loss. Researchers did find that people can lose weight by making aggressive changes at the outset, followed by maintenance with better habits. The study also showed that exercise can play a role.

So what better time to join Shape Up RI’s Family Challenge? The six-week program aims to get families to eat more fruits and vegetables, walk more, spend less time watching TV and on the computer and eat together. The contest begins Oct. 3.

Six weeks of that and you’re entitled to some grilled pizza.
