The Engine 2 Diet

Written by Rip Esselstyn, a professional athlete and firefighter, this book outlines a 28-day plan to transform one's health.

The diet, which originated in a Texas firehouse, focuses on whole foods including whole grains, fresh fruits, vegetables, legumes, nuts, and seeds.

It eliminates animal products, dairy, and refined foods.

The plan includes two approaches: the Fire Cadet plan, which is more gradual, and the Firefighter plan, which is more extreme.

The book provides dozens of easy and delicious recipes, pantry-stocking tips, and a simple exercise program to boost metabolism and health.
