Were you travelling in Europe? I typically lose weight while travelling because I'm walking more and have fewer snacks around. This includes months in the US last year where pace and timing of a lot of our driving meant we ate fast food a bit. It was hot so we couldn't stash chocolate/ice cream, we didn't have access to a fridge so we didn't scoff leftovers, etc. We mostly lived out of a cooler and cooked on fires. We walked around exploring cities/towns where many residents would not have though. The number of mobility scooters and the like is incredible.
