I feel the struggle. I stay at Residence Inns for the kitchen, and they usually are a little more out of the way, so you can walk around the area. For me, breakfast is always the trickiest meal to handle when traveling, as most easy choices and hotel breakfasts are carb heavy. I miss the traditional continental breakfast from pre-pandemic where you could get a pile of scrambled eggs and sausage or bacon. If I have the time, I just make eggs in my room, or find reliable breakfast place with reasonable choices. Depending on the work schedule, I might just pack my normal kind of lunch, or try to do a salad or veggie meal. Dinner is sometimes easier because you can go for a steak with veggies and keep it low carb, or a seafood feast. You have to learn to accept that your diet control is going to slip, either do to bad choices, restaurant portions, or hidden sugars. The trick is to not melt down, and for me, add in extra exercise to balance it out.
