Why The Myrna Method

Why Work With Myrna

Myrna has had a passion for nutrition since her early twenties when she struggled with a weight problem that resulted in disordered eating patterns, malnutrition, and low self-esteem. Also, Myrna learned that a great exercise plan will never outperform a bad diet. Myrna ate the typical Western diet with Yo-yo eating patterns that led to weight loss and weight gain. It was this frustration that led her into the field of nutrition, to find answers to today’s obesity epidemic.

Myrna’s research resulted in her current philosophy: that nutrition is not about a single food group or diet, but an individualized approach that takes into consideration a person’s individual chemical make-up. She developed and follows a nutrition balancing technique that turns off the metabolic triggers to over-eat, resulting in over 20 years of maintaining an ideal body weight and helping others reach a diet free approach to their leanest and healthiest weight.

Myrna’s enthusiasm for nutrition and helping others grew into a private clinical nutrition practice. As a registered and licensed dietitian, she provides nutrition therapies for treatment of chronic illnesses and is an active part of her patients’ medical team. The MyrnaMethod is her clinical practice philosophy that guides a patient through a system of nutrition that has been researched and proven to improve chronic illness symptoms and maintain an ideal body weight.
