> That's where intermittent fasting is crucial Would you be able to use IF during a thru hike? I suspect that the answer is no. The weight gain problem for distance hikers is after the hike is finished and we reduce activity significantly. I've solved that by training for distance races when I'm not hiking. Zach Bitter, the current 100 mile record holder, put it in a way that makes a lot of sense to me[0]. For a mere mortal, fasting for 6 hours puts you in the hole for about 700 kcal. A world class athlete like him is at more like a 2000+ kcal deficit. It's impossible to catch up once you get that far behind, and you end up losing weight and injuring yourself. I only burn about 800 kcal during training on an easy day, but I still find it nearly impossible to catch up if I miss a meal. I'm already eating 5x a day. It's hard to cram 5 full meals into a few hours.
