When it comes to indulgence, the Double Down isn't the only bad boy on the block. The Wendy's Baconator boasts 610 calories, 35 grams of fat and 1,130 mg of sodium. Meanwhile, Burger King's Triple Whopper with Cheese lives up to its name with 1,250 calories, 84 grams of fat and 1,600 mg of sodium.

“It's a really worrisome trend,” said Ms. L'Abbe. But there may be a grain of goodness in all that fat and salt: the buzz around products like the Double Down may end up getting Canadians talking about issues like sodium intake.

“It's very difficult to make them choose not to consume those products, but it's even worse if they consume them without knowing.”

The Double Down's debut in the U.S. last year has touched off a domino effect of overly indulgent take-out products, sort of like the extreme-sports version of fast food, said Debi Andrus, a marketing expert at the University of Calgary.

“Who in there wants to be left out of the big, juicy, meaty, high fat, high sodium choice?” Ms. Andrus said. “As soon as one starts it, then the others will look at, ‘Well, what can I do to compete with that?“’

The fast food chains are tapping into a demographic that is pushing against the healthy eating trend and giving in to a product that's being unabashedly upfront about being unhealthy, Ms. Andrus added.
