After going from meal bags to high protein pasta, Isolator Fitness has once again introduced something a little different than usual. The brand has actually launched an eBook called the Encyclopedia of Meal Prep, which is exactly what it sounds like. The Isolator publication is a 216 page guide focused around cooking, foods, techniques and more. Some of the book’s highlighted topics include Gains of Grilling, Benefits of Brining, Understanding Nutrition Labels, Food Substitutions and Bulk Buying. Those interested in giving the encyclopedia a read can either purchase it from Amazon for $2.99, or grab it free from Isolator’s website.
