I have McD's breakfast quite often - a round egg, no cheese (as it's plasticky and horrible) and I swop the hash brown for a cucumber bag. I have a bite of the muffin, no more - can order without, but its easier to hold the egg with it ! And a regular coffee. Never spikes my sugar - 2hr reading up to around 6.4 from a early morning 5.5 ish or thereabouts.
You can customise McD's to suit, reasonably. bacon, sausage, burger meat, grilled chicken salad, etc. Order water instead of pop, diet or otherwise - much healthier. I have the Carbs and Cals app on my phone so I can look up fast food if needs be, but generally have found options which don't spike my BS.
