Can you exercise off a bad diet?

    MAYBE, JUST MAYBE, if you squat till you drop and burpee into oblivion you can burn off those fried fish tacos, chocolate frosted donuts, and bags upon bags of Funyuns.

    It’s a nice thought—and people definitely try. But, sadly, you can’t exercise off a crappy diet. Science backs it up. In one study—literally entitled: “It is Time to Bust the Myth of Physical Inactivity and Obesity: You Cannot Outrun a Bad Diet”—published last year in the British Medical Journal, researchers confirmed this, and also argued the over-emphasis on physical exercise at the expense of dieting encourages manufacturers to create a “health halo legitimization of nutritionally deficient products.”

    The burn-and-refuel mentality is dangerous. If you burn 600-800 calories boxing, in a HIIT session, or running then treat yourself to a double cheeseburger, then yeah, your fat loss has just become a herculean struggle.
