During digestion, proteins break down into amino acids that your body uses to build and repair muscles. However, proteins do not provide the quick release of sugars needed for strenuous hiking and consequently are not as important to the hunter's diet as are carbohydrates. Most nutritionists recommend a daily intake of only 10 to 15 percent protein, which can easily be met by eating small portions of meat with the evening meal, an egg for breakfast, or a protein-rich trail food such as jerky. Dairy products are also high in proteins. When you eat can be nearly as important as what you eat.
Nutritionists recommend eating a half dozen smaller meals a day, rather than two or three big ones.
The body digests food more easily in small quantities, and by snacking periodically, the bloodstream is assured of a steady release of sugars to keep you moving. Probably more than you think. I once went backpack elk hunting with a woman who was a personal trainer. The first thing she did when we returned to civilization was stand on a bathroom scale. You can eat all that you want, everything tastes great, and you still lose weight.
