Don't need to start running. Don't even need to give up the McDonald. Quit the high fructose corn syrup drinks, nothing but carbs fries, and instead get a water or diet and for the meal get 2-3 McDoubles, strip off the shitty buns from the top of one and bottom of another and make a mostly protein and fat quad (or strip the bun entirely off a third and make a hexa) burger.  It's lacking in nutrients a bit, but at least that way the meal isn't just shitty empty hog feed carbs. It's what I do when I need a meal in a pinch and have no other options. It's the HFCS shit drinks, fries and especially the buns that's unhealthy there, unless of course you're living in the '50s and haven't bothered to learn that fat doesn't make people fat, empty carbs do. I'd still rather just have a steak and a package of spinach with sauteed onion and bacon mixed in at home...but that's not always the option. At around 850 calories, 30g carbs, 66g protein, and 55g fat, a hexa burger with two of the buns (around 300 worthless carb calories of bun alone) tossed in the trash isn't a terrible meal on the go.  The problem is the stupid fats don't strip the bun, so that's 140 calories x2 they're eating with zero nutritional value. Then the nutritionally worthless large fry, another 510 worthless carb calories, and they wash it all down with hundreds more beetus inducing carb calories of hfcs soda. Their meal weighs in around 1000 worthless carb calories more than mine, and they wonder why they're fat when that skinny fuck ate three burgers too and isn't fat.
