It doesn't matter who I'm coaching, the main concerning question is, "but what do I snack on?"
Below are simple products I personally love and use!
In general, I follow a Paleo/Low Carb lifestyle so these snacks reflect that. Some are both Paleo and Low Carb, some are Low Carb but not Paleo. They are all zero to low carbohydrate and most of which you can pack with you wherever you go.
