About Us

e3 Weight Management System is Glen’s concept and formula for success, as it focuses on three principals: Eating, Exercise and Education. The secret to controlling body composition and weight loss is balanced energy. The desired goal for most of us is to lose weight; however, our goals should be to change the shape of our bodies by reducing body fat, increasing our energy levels and improve our overall health.

Feeling better and changing body composition through fat loss is as simple as the Energy Equation – “Energy In (eating) vs. Energy Out (exercise).” “Calories” mean energy. Simply stated, to lose body fat, calories expended must be greater than calories consumed. The focus of the e3 Weight Management System is to help you change your body composition and improve your overall health through the understanding and management of energy. e3 is a scientifically-based weight management system created to provide safe and effective results to help you look and feel better. It is designed to work with your eating habits and provide you with the knowledge necessary to help you modify your lifestyle.

The “e3 Essentials”

Eating, Exercise and Education are the keys to the step-by-step application that will help you manage your weight for safe, long-term results, finally ending the fad diet trap and improving your overall health.

With the sun beating down, a vital thing we need to focus on is…Hydration! Water makes up approximately 60% of adult body weight, and it is considered an essential nutrient because it must be obtained from sources outside the body. It is necessary for reactions in the body that involve nutrient digestion, absorption, transport, and […]

Soda And Athletes

Soda is not hydration – its liquid sugar calories; and as a professional athlete you want to eat your calories, not drink them! (An exception would be a protein shake) Many athletes think of soda as a liquid, but it is actually like icing on a cake, all sugar! Even diet soda, although calorie-free, has […]

Dining Out

Dining Out Go out, enjoy and get dressed to the nines, while remembering these nine Do you find it stressful going out to eat while trying to stick to a healthy lifestyle of eating?  If you answered “yes” you are not alone.  Food and eating have become more than just a way to stay alive. […]

“There are no bad foods, just degrees of better.” Weight management is all about calorically cheapening the meals you are eating; cheesecake is not bad, it is delicious … but [calorically] expensive. Carrots are much cheaper! The quality of the food is also an important component that Glen customizes to each client/athlete.

He teaches, guides, and monitors his client’s adherence with optimal ratios of macronutrients; proteins, carbohydrates and fats. His meal plans are designed to maximize satiation from meals, incorporate hydration programming, and improve sleep (not just duration, but rather when and how deep an individual’s sleep patterns are).
