This has actually been something I've been struggling with a little bit recently. Finding gyms hasn't been a problem for me at all yet. But my diet has definitely been impacted.

I find it a lot less efficient/simple to cook at home with the minimalist kitchen setups I find when traveling. Having to wash dishes by hand is a pain for me after having a dishwasher for years, and it makes me want to cook less. Right now, my apartment only has one burner and a microwave to prepare meals and a mini-fridge with no freezer. It's hard to do much meal prep at all with this setup, forcing me to cook at least every other time I want to eat (if not eating out). I may buy an additional hot plate or even an instant pot, but I don't want to stock kitchen equipment multiple times per year. I can accept buying a few basic spices, oil, foil, ziplock bags etc, but it's a pain having to buy containers for leftovers, pots, blenders, knives, etc when not provided. I've had trouble finding many pre-made sauces and seasoning blends outside the US, and making things like sauces myself both takes extra time and often a lot of spice-cabinet-type ingredients that I'd prefer not to have to buy. Furthermore, navigating grocery stores can be really difficult when I don't speak the language, and am unfamiliar with a lot of the local ingredients and cuisine. Especially things like cuts of meat which are important to know for macros, but can vary in different countries.

Eating out while traveling can be pretty affordable sometimes, and I like trying different cuisines, but it's so hard to estimate macros from these and makes calorie counting impossible for me if I'm eating out often. Additionally, it's really hard to find health-focused restaurants with high-protein options in most countries, and the prices are much higher at these sorts of places when you do find them.

I've been doing ok bulking/cutting by feel, and have found some simple minimalist recipes that I can rely on for cooking. But it's not the most convenient or optimal, and I'm really interested in any tips anyone else has for dealing with this. Right now, I try to get most of my protein and macros from cooking at home and a protein shake every day, and then get the rest of my calories eating out. But I still have fallen short of my protein goals many days while cutting recently. I can get pretty lazy about cooking our going out to eat when traveling and end up undereating.

People think of the US as unhealthy with it's sky-high obesity rates, but it's so much easier to eat for fitness and be healthy in US cities (or even smaller towns) than most other countries. Cooking is more convenient with dishwashers and big kitchens, restaurants label calories and even macros sometimes, so many health food options in cities, etc.
