A Paleolithic Diet vs. Eating for Endurance

While humans living in the Paleolithic and even earlier (pre-fire) times appeared to have been relatively healthy, their life span was not very long. Since those times we have adapted to a rather different pattern of eating – a higher carbohydrate intake from the addition of grains, cereals, starchy vegetables, milk products, and a variety of fruits in fresh, dried and juice form. This pattern is associated with the long life span we now have AND this pattern of eating fuels endurance athletes to train hard, recover and repeat on a daily basis (See Table below). While the Paleolithic diet may give you enough fuel to maintain your cross country skiing and other endurance training note that it is a high volume diet; that is, you have to eat a lot of vegetables and fruits to get a sufficient amount of carbohydrate INTO your muscles to ski, run, cycle or swim fast and far. These types of plant foods have a tendency to fill you up and quash your hunger BEFORE you actually have sufficiently refueled. It might take you a few days of training to realize that you haven't been refueling adequately – and you will know because your endurance performance will be negatively affected and even easy workouts will feel hard. Make some slight adjustments to the Paleo diet by including some non-Paleo foods before, during and after your training. Start by including dried fruit and/or high glycemic index fruits in your pre-workout snack and then add potatoes (roasted, mashed, baked or boiled) to your post workout meals. If you are going to be using sport drinks and gels during your race then you should get used to them in your longer distance training sessions. These slight adjustments to your dietary intake on your training days should help to optimize your energy level during your training sessions.
