Dr. Brian Lenzkes, MD

I have struggled with weight gain and obesity my entire life.  I was overweight as a child and thinned out in High School after cutting weight (through starvation and excessive workouts) from my football weight of 205 lbs to my wrestling weight of 165 lbs…in about 6 weeks.  Crazy stuff but I could do it then.  It was tough then, but is virtually impossible now!

​I went to UC Irvine and received a BS in Biology before attending USC Medical School.  After graduating in 1999, I started my Residency Program at Scripps Mercy Hospital in San Diego and stayed on for an extra year as Chief Resident before starting my private practice career at Internal Medicine Associates in 2004.  I have been voted one of the “Top Doctors” in San Diego for 11 years.  Even with gaining the respect of the medical community,  I felt helpless as I watched my patients become more sick and require more medications.  At the same time I continued to gain weight while following standard medical advice.

​I can sum up my nutritional training from medical school, residency, and private practice as follows:  “Don’t eat fat, it is bad for you and clogs arteries.  Take vitamins.  Exercise more and eat less. Never skip breakfast, eat 6 small meals throughout the day so your metabolism doesn’t shut down.”

​I followed this advice my entire career…until I reached my highest weight in February of 2017…while working out 6 days per week for at least an hour and eating 6 small, lowfat meals daily.  After struggling to button my pants and buckle my belt, I would head into work and take care of patients who would ask me “Doc, how do I lose weight?  Isn’t there a pill I could take for this?”  My response: “Don’t you think if I knew I would be taking the “magic pill” myself?”  Then I found out about lifestyle modifications that actually worked including the Ketogenic Diet and Intermittent Fasting (IF).  I was initially surprised by the available science in this area and now I am overwhelmed by how vast it is. How could the medical community at large not know about this? I would love to share my knowledge and personal experiences with you.  I am currently down nearly 50 lbs after making some “evidence based” lifestyle changes. We can improve or reverse metabolic diseases including Type 2 Diabetes, obesity, fatigue, and mood disorders while at the same time decreasing our risk for catastrophic diseases such as cancer, Parkinson’s, and Alzheimer’s Disease.  There is no “magic pill” but there is a path forward if we have the courage to take the first step.   I would love to take this journey with you and build a community. I work together with TriSystem as part of my integrated metabolic health practrice.
