Which likely caused the weight loss?

So i haven't exercised since sometime in December. I got back from the trip Tuesday of last week. The trip consisted of daily walking and stair climbing, one day of swimming, and some daily X-rated marathons. I lost 7 pounds in 7 days. Thats like never happened even when i’d exercise like crazy for weeks at a time. Plus i’d be dieting. I did not diet on the trip. He and i ate like crazy after some of the shit we did lol. So Which activity above likely helped even though im sure they all played a part? 😭👌 If it turns out that xXx is the answer, that explains a lot in regards to the body i had as a teen and in my early 20s 🤣 #FeelFreeToList

I spent like 60 seconds in the sauna so i doubt that helped 🤣 I spent like an hour in the hot tub so maybe that did something? But yea im sure taking the stairs did some major work to my thighs. Walking in general probably kept the tummy flat. But i just dont get how i lose 7 pounds in days of unhealthy eating vs months of exercise and healthy eating just to lose the same amount.
