McDonalds is actually OK for Keto. The restaurant is built on the principle of trying to trick you to have carbs so you still feel hungry and buy more, but actually the meat on its own isn't terrible. A couple of double cheeseburgers without buns in a stack makes a good meal. If you're really after the burger feeling, get two mayo chicken burgers without mayo or buns and use the lightly battered chicken burger as your "bread" and in the middle have a double cheeseburger without buns. Fortunately this combo doesn't have the nickname in the UK as it does in the US, but I'm always a little self-conscious when I'm eating it, just in case anyone around does know and what they might think of me! Also, in the UK at least, 3 items from the saver menu costs roughly the same as a normal meal deal, is much more filling and obviously keto friendly.
