Your body needs fuel to perform, and Paleo workouts are intense, so a strong showing requires a meal before working out. You want to eat anywhere from one to three hours before you work out if possible. Now, some people can do pretty well exercising in a fasted state, so just play around with different pre-workout timelines to see what works best for you.
Pre-workout foods that tend to work best for most people are proteins and fats. You can keep it super simple and eat any of the following dishes with diced avocado, guacamole, or a nut-based pesto.
Canned fish (check the label for soy)
Leftover meat
Preservative-free and nitrite-free deli meats
Eggs with bacon
Hardboiled eggs
Nuts
Smoked salmon
Bacon and avocado
Olives
Coconut meat, chips, or manna
Nut butter
Shrimp and macadamia nuts
