Cyrus Khambatta

Dr. Cyrus Khambatta received his PhD from the University of California at Berkeley in 2012, and started Mangoman Nutrition and Fitness in 2013 to teach people with diabetes the fundamentals of lifestyle management through informed nutrition and exercise. By providing nutrition and exercise coaching, he aspires to positively influence the lives of people with both type 1 and type 2 diabetes.

Dr. Khambatta teaches individuals how to identify poor lifestyle habits that can reduce energy levels, create insulin resistance and worsen blood glucose control. His clients follow a 6-month small-group community based curriculum that focuses on plant-based whole foods nutrition and strategic fitness training. The program is modeled after a highly effective evidence-based approach from human clinical trials that focuses on small-group interaction to provide the two factors that promote successful lifestyle change: accountability and community.

Dr. Khambatta’s goals as a coach, educator and scientist are simple: to inspire people with diabetes to live in the driver’s seat by adopting lifestyle habits that reverse the effects of insulin resistance. The epidemic of diabetes is a very preventable phenomenon, and it is therefore vital for people with diabetes to understand that focus, determination and impeccable habits can lead to a disease-free future.
