Specialty in teaching the Paleo Lifestyle to those seeking a practitioner who understands this lifestyle. Proficient in helping the obese and overweight to avoid diabetes, heart disease and many other health problems see in our culture due to "Diseases of Western Civilization".


Chrystyne pursued a career in nursing for the ultimate goal of helping those with diabetes. This passion developed after her son was diagnosed with type 1 diabetes at 16 months old. The whole family was then on their way to a very healthy lifestyle with a low glycemic index carb, high protein and healthy fat diet. All leisure time was spent in physical activity as often as possible. This has resulted in 3 fit, lean, muscular young men (including the one with T1DM). Because she has seen the results of a healthy lifestyle in our current social climate of obesity & type 2 diabetes, this translates into her practice and her patients benefit. Discovering the Paleo lifestyle has only reinforced what she has always believed: that a low carb, high protein & fat diet is the way to a healthy body & mind.
