A new health study says the obesity epidemic could be reversed easily by reducing serving sizes.
Researchers at the University of Cambridge in Britain say today's portion sizes make it too easy to overeat.
And they say when we're offered bigger portions, we generally eat and drink more than when we're offered smaller portions.
"At the moment, it's just all too easy and often a better value for money for us to eat and drink too much," said Ian Shemilt, a co-author of the review.
To give you an idea of how portion sizes have increased, take this example.
About 20 years ago, a coffee shop muffin tended to be 2.5 ounces (71 grams) and 210 calories. Today, they can be 113 grams and up to 500 calories.
Dr. Danielle Martin has seen the effects of those bigger servings & what we can do about it.
