Women often do better late in the trail over men because they are much more efficient at metabolising fats and at the end they look great and the guys usually look like concentration camp survivors. So, if you are the latter you must force the protein and calories at times to keep from hitting a wall nutritionally. Oddly, you'll find that you can live on the densest of foods like sausages and little debbies and "cameling up" on periodic breakfast buffets and sweet trail town cuisine whenever you can and is essential for many to maintain weight. For many it will be one of the only times in their lives they will experience the feelings of fat deficiency. Get the tuna in oil over water and use all of it with your dehydrated ramen.

If you have the opportunity to thru-hike, do it or accept that you are going to take a different path. That window doesn’t stay open long for most people so don't assume you have plenty of time later in life. Doing it changed everything for me.

Good luck! Please ask me any questions.
