Our Dietitians

At F-Factor you’ll work with a registered dietitian who is also certified in F-Factor’s proprietary nutritional method, which is based on more than 20+ years of clinical experience helping clients achieve their health and weight goals.

We don’t just hand our clients a meal plan. We educate them about food and how the body digests, utilizes and stores nutrients so it is easier to focus on eating more of the right kinds of foods. We also spend time listening, which enables us to tailor the F-Factor Diet to their needs, tastes and lifestyle.

Why work with a Registered Dietitian?

Registered Dietitians are food and nutrition experts who apply the science of nutrition into practical solutions for health living, using their clinical expertise to help individuals make personal, positive lifestyle changes.

The “RD” credential may only be used by practitioners who are authorized by the Commission on Dietetic Registration of the American Dietetic Association. Individuals with the RD credential are leaders in the field of dietetics who have fulfilled specific requirements, having earned a least a bachelor’s degree (about half of all RDs hold advanced degrees) in nutrition and food science, completed an accredited, supervised practice program, passed a rigorous national examination and maintain their skills by meeting the profession’s continuing education requirements for re-certification.

While RDs are sometimes referred to as “nutritionists,” not everyone who uses this title is a “registered dietitian.”  In many states anyone may designate themselves a “nutritionist,” regardless of education or training.
