I'm in the Army and I've been Paleo for about 3 months. I'm just looking on tips for ways to keep my energy level up throughout my days. I typically have early mornings and late nights and my job requires me to be able to sustain high levels of energy out put for long duration's. I use to use gel packs and energy bars during these events and I'm looking for alternatives to these. I read that most athletes just increase their intake of sweet potato's but I was wondering if anyone has any other tips.
