We overlanded (the posh way) through China and Tibet last year for 2 months just before my first wls. Husband told me at least once a day that I was going to die with the surgery. I had 'one or two' issues with food then, and it was a complete nightmare culinary wise. Comfort wise, Tibet is an utter nightmare, the toilets are a sight to behold, plus the political situation can change with the wind. Fascinating experience though. We just literally completed our sector in Tibet before it was closed to tourists the next day.
We then overlanded and backpacked over the winter through South America, 6-8 months post op. Food was difficult, and eating slowly and with tiny portions in company was uncomfortable. The camping had no difference in comfort with wls. It was still bloody awful as it always is
. Definitely went with a roughing it company, that I hate, you get to far flung places, but not a company to recommend.
I took protein powder with me and bought a 'herd of cows' load of UHT milk to take overlanding and mainly lived off that, as there wasn't much else that I could eat. Breakfast was high sugar unsuitable cereals or bread. Dinners were buckets of pasta (no way!). Beef, no way!
When we left the truck, and cooking facilities things got worse as no access to self catering etc.
We also went on a cruise boat, where 99.8% of the food was unsuitable.
We are going away later this year and the company has a comprehensive list of what I will eat. I don't want to be the only person on the boat that loses 3kg on an all you can eat, 24 hour a day food cruise!!!! After that we are self catering. I will also be trying to take protein powder with me, just in lots of tubs.
Wls certainly has affected my choices of holiday and the ability to eat. Luckily we have been to most places on the planet already!
