McDonald's - opt for any burger (zero g) or grilled chicken (2 g) without the bun and topped with cheese, mayo, mustard, onions, etc. No ketchup. Add a side salad (3g). The Caesar salad with grilled chicken or the bacon ranch salad with grilled chicken are 9g. BONUS - dessert!?! - the fresh apple fries are not fried and are 5g net carbs WITHOUT caramel sauce.
