About Dr. Lenzkes

Dr. Lenzkes is the Medical Director at San Diego Metabolic Health. He is board certified in internal medicine. Much of his focus has been on clinical nutrition.

His care uses lifestyle changes such as the ketogenic diet and intermittent fasting. He received a Bachelor of Science in Biology from UC Irvine and graduated from the University of Southern California medical school in 1999.

He started his private practice career at Internal Medicine Associates in 2004. From 2004 to 2020 he owned a practice alongside a group of physicians, and then he moved to an independent, membership-based practice named LowCarbMD San Diego.
