Newshub's Dan Satherley says next time you're asked if you'd like fries with that, don't be surprised if one of the options is 'six'.
That's the maximum number anyone should eat in a single sitting, a Harvard nutrition professor has claimed.
Eric Rimm told the New York Times potatoes are "starch bombs" made only worse by removing their nutrient-filled skin and frying them in oil.
He's urging people to give up the fries and opt for a salad instead. But if it's fries you want, Dr Rimm says moderation is key.
"There aren't a lot of people who are sending back three-quarters of an order of French fries," Dr Rimm told the paper. "I think it would be nice if your meal came with a side salad and six French fries."
