“After years of being dedicated to my workouts and eating what I felt was healthy, but still not seeing  movement on the scales or the changes I wanted to see in my body, I decided to hire a nutrition coach.  Dr. Tiff unlocked the key for me to losing weight.  I had been “stuck” in the same 3 pound range for years and with Dr. Tiff’s advice on how to eat a true balanced diet, I found I ate more carbs than I had had in years and the weight started coming off.  I couldn’t believe it! Dr. Tiff has truly changed my thinking on food/nutrition and it has changed my life.  I have lost over 20 pounds and 9% body fat to date.  Hiring Dr. Tiff was the best gift I could have given myself!”
