I will start my spring A.T. thru hike pushing 140 lbs. The heaviest weight that I've ever been was 150 lbs. I'm not a big fan of food but, could gobble down an entire turkey and gain nothing. Have you ever met any thru hikers beginning their long distant hike this light? I have a weird body system when it comes to food. I have more than once gone an entire day without eating anything and still function as normal. I have a very strong mind to overcome what my body lacks. Any thoughts for this skinny hiker?
