How Does Michael know Michael?

I’ve known Michael Sylvester since 2002 and we’ve been colleagues and friends ever since. We often hold similar views and treatment philosophies on various health topics especially weight loss. As a registered dietitian, certified health coach, and certified personal trainer, I’ve had the pleasure of working with many of Michael’s clients who struggle with weight loss to embrace healthful eating, find peace with food, and design and implement tailored eating plans to meet their individual needs, goals and lifestyles. Many don’t realize the dietary component far outweighs one’s exercise efforts when it comes to inducing weight loss. Though physical activity is key, however, in maintaining the lost weight, you can’t “out exercise a bad diet” as the saying goes. My services can be conducted completely over the phone, which is convenient for most people, given the nature of our busy lifestyles.
