Swapping the medium Coke for Diet Coke or water saves 210 calories instantly. Going from medium to small fries saves another 90. That takes a 1,110-calorie meal down to around 810 without touching the burger. If you want the Big Mac taste for fewer calories, a McDouble with Mac-style sauce gets you close for 390 calories.
