Bert Herring, MD, known as Dr. Bert, is a pioneer in the field of daily intermittent fasting. He first experimented with this approach in 1995 and later published his findings in 2005 with the release of his guide, "The Fast-5 Diet and the Fast-5 Lifestyle." Dr. Bert emphasizes practical solutions that cater to the lifestyles of everyday individuals, particularly those balancing work and family commitments. His skepticism towards short-term studies and results that do not apply to real-life situations informs his approach to health and wellness.

In addition to his work on intermittent fasting, Dr. Bert is dedicated to providing sustainable health solutions that extend beyond diet. He believes in equipping people with the tools necessary to combat societal pressures to overeat and to develop a balanced lifestyle that is maintainable in the long run. His TEDx talk, "Did I Enrich Today?" has garnered over 175,000 views, further showcasing his commitment to promoting a holistic view of health. Dr. Bert's published works include titles such as "AC: The Power of Appetite Correction" and "Dr. Bert’s D.I.E.T. AC ToolBook: Flow Edition."
