BOSTON (WHDH) — The calorie count of every item in the machine will soon be required on about five million vending machines nationwide.

The goal is to help people make healthier choices when they go for a snack.

Many restaurants have already added calorie counts to their menus and one study found people who read them usually ate about a hundred fewer calories.

"On the upside of this, losing 100 calories a day can help you lose 10 pounds in a year,” said Dr. Madelyn Fernstrom, NBC News Health and Diet Editor.

The FDA says if just 0.2 percent of obese adults ate a hundred fewer calories a week the health care system could save $24 million a year.

Once the FDA releases the new rules early next year, vending machine companies will have a year to comply.
