When I began my doctorate in nutrition and human performance in 1983, I never would have imagined that the field of sports nutrition and its practice would become known and popular worldwide. Since completing my doctoral research on steroid-using and non-using competitive male bodybuilders in 1987 I have had the great fortune to continue to contribute to the research body of literature on male and female athletes in sports nutrition science; educate several new generations of sports nutrition practitioners, exercise trainers and coaches; consult with teams and athletes at all levels of sport from professional to Olympian, collegiate to recreational and everyday athletes; consult with business and industry to provide expert advice on product research, development and marketing; and even co-found an academic society for sports nutrition, the ISSN.

It took 10 years after the publication of my doctorate before there was enough nutrition scientific publications raced ahead and since 1998 a new edition has been published approximately every 5 years. Every edition contains nearly a full new book of information, and The New Power Eating is packed with the latest, cutting edge science, evidence-based recommendations, and diet and supplement guidance based on my 35 years of research and practice in high performance nutrition.

My first introduction to Vitargo came from a French national rugby player client, just prior to Vitargo distribution in the USA. According to that athlete, Vitargo was a game-changing carbohydrate fuel, and he was right. Ever since then I have been recommending Vitargo to my clients who can benefit from fueling their performance (think: nearly everyone!). I have never worked with a sports nutrition company in the way that I currently work with Vitargo. Vitargo’s commitment to science and transparency is perfectly aligned with my ethics and my brand.

In The New Power Eating you will learn about how to fuel your training, your body and your brain using food when you can and supplements when you must. There are Power Eating plans for male and female athletes from novice to elite levels to maintain muscle, gain muscle, cross train, lose fat, and get cut. You will learn when food is your best choice, and when and how Vitargo can give you the competitive edge you desire.

You can have it all. Train hard and Power Eat! – Dr. Sue

Sample Planning A Peak Ch 14

Sample Getting Cut Menu Plans Ch 19



In February of 2016, I worked with a 25-year-old female Olympic gold medal swimmer preparing for the Summer Olympic Games in Rio. She was concerned about her body weight. When she competed at the previous Olympics, she had weighed less than her current weight, and she worried that she was too heavy to compete. During the past three years, she had added resistance training to her regimen and was currently 24 percent body fat. In order to lose weight, she had put herself on a very restricted diet of 1,535 calories, 195 grams of carbohydrate, 77 grams of protein, and 50 grams of fat. She had read that she needed to decrease carbohydrate to lose weight. She especially avoided fueling around training to increase weight loss. However, she reported feeling exhausted, irritable, and so hungry that when she returned home after practice she couldn’t stop eating. Her performance had diminished significantly.

This athlete’s resting metabolic rate was 1,700 calories a day. Her general calorie usage during training was 600 to 800 calories an hour, or sometimes more, depending on the training sessions. She trained an average of 4.5 hours a day, 6 days a week. However, because she was so dramatically underfueling, she was not optimizing her training, nor did she have the fuel to support her foundational health needs.

Her regimen needed some serious overhauling. So that she could continue to train intensely, I added food in to her diet slowly, along with supplementation that would rapidly empty from her stomach and not cause gastrointestinal distress. Specifically, I increased her daily food intake to 2,050 calories, 200 grams of carbohydrate, 157 grams of protein, and 64 grams of fat. This allotment allowed for wiggle room so that she could add her favorite foods—which amounted to an average of 500 extra calories a day, bringing her food total to 2,500 calories per day.

I had her supplement with up to 300 grams a day of carbohydrate (another 1,200 calories) supplementation (Vitargo), depending on the intensity and duration of each workout. She would take a preexercise dose, a dose during exercise, and a dose afterward. Her postexercise dose was combined with 20 grams of whey protein isolate. This was often a morning and an afternoon supplement regimen around training.

By April, this athlete lost 3 pounds of body weight, maintained her muscle mass, and had regained her Olympic caliber swimming performance. She went on to make the Olympic team and win again in Rio.

I see this same scenario day in and day out in my office, in female and male athletes, but most dramatically in females. Female athletes typically underfuel by 1,000 calories per day. In this case, with this Olympian, she was below her final competition level calorie intake by nearly 2,000 calories a day.
