San Diego Metabolic Health & Direct Primary Care, the Santee practice of Brian Lenzkes, MD, operates a membership-based clinic at 280 Riverview Parkway dedicated to reversing metabolic disease through evidence-based nutritional and lifestyle intervention. Baseline and follow-up blood panels including fasting insulin, hemoglobin A1c, and comprehensive lipid profiles process through nearby laboratory services at Sharp Rees-Stealy Santee Laboratory on Cuyamaca Street. Dr. Lenzkes earned his medical degree from the USC Keck School of Medicine, completed residency at Scripps Mercy Hospital, and has been recognized as a San Diego Top Doctor for eleven consecutive annual cycles. The practice uses continuous glucose monitoring data, coronary artery calcium scoring, and DEXA body-composition scans to quantify metabolic risk and track therapeutic response to carbohydrate-restriction protocols. The practice's integrative approach to metabolic recovery extends to complementary pain-management and stress-reduction referrals at Santee Acupuncture on Mission Gorge Road for meridian-based interventions. Type 2 diabetes reversal protocols target fasting insulin levels below 10 µIU/mL through therapeutic carbohydrate reduction combined with structured time-restricted eating windows calibrated to individual circadian glucose curves.
