Dr. Hana Kahleova, M.D., Ph.D. is a medical doctor and researcher. Her current research interests focus on alternative dietary treatment of type 2 diabetes. Dr. Kahleova conducted a study with a vegetarian diet and wrote a book Vegetarian diet in the treatment of diabetes (Maxdorf 2013, in Czech). Her latest research proved that eating a large breakfast and lunch is more beneficial than eating six smaller meals a day for patients with type 2 diabetes. Dr. Kahleova is a member of the Czech Diabetes Association and the Diabetes and Nutrition Study Group of the European Association for the study of Diabetes (EASD). After her postdoctoral research fellowship at Loma Linda University, CA, she is now Director of Clinical Research at Physicians Committee for Responsible Medicine in Washington, DC.
Accumulating evidence suggests that circadian de-synchrony may be an important contributing factor in the development of chronic disease, including obesity, type 2 diabetes, cardiovascular disease and cancer. While our central body clock in the hypothalamus in entrained by the light and dark cycle, the peripheral body clock found in each cell of our body needs to be synchronized with the central clock, mainly through nutritional stimuli. More specifically, this can be achieved through the fasting and feeding cycle, with a plant-based nutrition, and through proper meal frequency and timing. As the insulin action is the most effective in the morning, eating breakfast enables us to use the energy from the meal more efficiently than from the same meal eaten later in the day. While snacks seem to disrupt our body clock, eating 2-3 meals a day, with breakfast being the largest meal, and dinner being the lightest meal of the day, is a great way how to synchronize our body clock. This brings us back to the ancient proverb: Eat breakfast like a king, lunch like a prince, and dinner like a pauper.
