Consuming 4,000-5,000 calories daily during 40-day, 20-25 mile/day outdoor adventures can result in a weight loss of approximately 13 pounds.

“So, for the last one, for example, that was 40 days. Um, we probably averaged 20 to 25 miles a day. Um, some days are a little more slowgoing because you might have to navigate a canyon. There's a lot of ups, a lot of downs. Um, but we also had sections on the Arizona Trail, which is like this really well-maintained trail. Um, so we had like a 40 mile day that day. Um, and you have everything in your pack, so you're carrying the pack. And I was trying to eat between 4,000 and 5,000 calories a day. And I still lost about 13 pounds.”
