In Running Doc’s Guide to Healthy Eating: The Revolutionary 4-Week Program to Boost Your Athletic Performance, Everyday Activities, and Weight Loss (HCI, April 28, 2020), readers will discover Dr. Lewis G. Maharam’s unique Fueling Plates program. Developed in 2012, it has helped countless people who want to make a difference in their life and lose weight, marathoners competing for a place at the Olympic trials, and everyone in between, including recreational athletes who play tennis, soccer, basketball and other running sports. The Fueling Plates program is designed primarily to boost the performance of athletes, but can also boost the health of the average person, athletic or not.

The Running Doc’s Guide to Healthy Eating explains why it’s time to ditch the old, difficult-to-use food pyramid put out by the USDA, or even it’s 9-year-old MyPlate,  in favor of a hands-on experience of your actual plate – Fueling Plates. The book shows, step-by-step, how readers can apply the program to feel and perform better and have more energy. Those who are already exercising will get faster by eating to fuel their body more efficiently. Even everyday activities become easier with the Fueling Plates program. Readers who are willing to take advantage of everything revealed in the book, from what to eat to reduce muscle soreness after exercising to how much to drink to be hydrated properly to individualized nutrition programs, will transform their lives. 

“I have followed the Fueling Plates program and still use it in my daily meal plans. I visualize how to separate out food into four areas on my plate and make sure to leave any extra food for leftovers. I also follow Dr. Maharam’s fullness scale and stop eating when I’m 80 percent full. That’s how I have maintained my body weight.”  — co-author Mark L. Fuerst

***In Memory of a Great Friend, Physician, and Running Coach  

It is with heavy hearts that we mourn the loss of Dr. Lewis Maharam, aka the Running Doc, one of the greatest contributors to the sport of running. Dr. Maharam dedicated his life to championing others to achieve their fitness goals and to be the best they could be at their sport of choice. He passed away suddenly in January, just after writing his last book, The Running Doc’s Guide to Healthy Eating, in which he was excited to share his unique Fueling Plates program with the world.

Dr. Maharam served as the medical director of the New York Road Runners Club and the New York City Marathon, which grew from a 24,000 person race in 1989 to over 43,000.  He was the past medical director of the Rock ‘n’ Roll Marathon series and the medical director of the Leukemia & Lymphoma Society’s Team in Training Program. He was Chairman of the International Marathon Medical Directors Association and a member of the American College of Sports Medicine’s Public Information Committee. He was appointed USA Team Physician in track and field for the 1999 World Indoor Championships in Japan and as the USA Team Physician for the USA Jr. Track & Field team that won the IAAF Championship in Sydney in 1996.

Throughout his career, he always treated professional and non-professional athletics with the utmost care. We will all miss Dr. Maharam, but know that his words, ideas, and accomplishments will live on through us in our sports medicine practices, our love of running, and through the many ways in which he inspired us to achieve our goals and live our healthiest lives.


“The Running Doc is back with his thoughts on nutrition and healthy eating. As one who has broken bread with him many times, I can testify he knows his way around good food. I highly recommend this book, which gives readers a simple approach to fuel their athletic performance, whether they are eating at home or on the go.”—Steve Van Camp, MD, cardiologist, past president of the American College of Sports Medicine

“I have known the Running Doc for many years. He is a complete sports physician, taking care of sports injuries, health, and wellness conditioning. With this book, he talks to you in a simple, easy to understand manner so you can eat healthy and perform better.”—Rod Dixon, four-time Olympian, Olympic medalist; two-time World Cross-Country medalist; New York City Marathon champion 

“Dr. Maharam has been advising runners on how to stay healthy for over forty years.  His latest book offers nutritional advice to fuel performance and prevent injuries. It should be on every runner’s bookshelf.”—John E. McNerney, DPM, former team podiatrist, New Jersey Nets and New York Giants 

“Sports nutrition is as vital a part to a runner’s success as is proper training. Dr. Maharam covers all the mile markers in The Running Doc’s Guide to Healthy Eating. A must-read for runners of all levels.”—Andrea Chernus, RD, CDE, CSSD, registered dietitian, certified specialist in sports dietetics
