COMPREHENSIVE DIABETIC CARE PROGRAM TARGETING INSULIN RESISTANCE: DOSE-DEPENDENT GLYCEMIC OUTCOMES, ANTIDIABETIC DRUG REDUCTION, AND GTT-DOCUMENTED REMISSION IN URBAN INDIAN ADULTS WITH TYPE 2 DIABETES — A RETROSPECTIVE COHORT STUDY

Background: Insulin resistance is the foundational metabolic lesion of type 2 diabetes mellitus (T2DM), driving both progressive beta-cell failure and the accumulation of cardiovascular risk factors. Pharmacotherapy addresses symptoms of insulin resistance but does not reverse its root cause — excess adiposity, sedentary muscle metabolism, and chronic low-grade inflammation. Intensive lifestyle interventions combining caloric restriction, exercise, and metabolic therapies have demonstrated T2DM remission, but real-world implementation of multimodal insulin resistance reversal programs remains limited. This study reports outcomes from the Comprehensive Diabetic Care (CDC) program, a structured multimodal intervention combining very-low-calorie dietary modification, structured botanical therapy targeting insulin-signaling pathways, physical conditioning, and antidiabetic medication tapering. Objectives: To evaluate the clinical efficacy of the Comprehensive Diabetic Care (CDC) program — comprising caloric restriction, structured herbal per-rectal therapy (Panchakarma) (structured botanical per-rectal therapy with Gymnema sylvestre, Berberis aristata, and Glycyrrhiza glabra), exercise and yoga — on glycemic control, anthropometric parameters, insulin resistance surrogates, and antidiabetic drug reduction; to quantify the dose-dependent relationship between treatment intensity and outcomes; and to report Oral Glucose Tolerance Test (GTT) outcomes as a remission criterion. Methods: Retrospective observational study of 79 consecutive T2DM patients enrolled in the CDC (Comprehensive Diabetic Care) program at an integrative metabolic clinic in Mumbai, India. The multimodal intervention included: (1) an 800 kcal/day low-carbohydrate, high-protein dietary program (Prameha diet); (2) Panchakarma comprising herbal oleation, medicated sudation, and per-rectal botanical therapy delivering berberine, gymnemic acids, and glycyrrhizin via direct colonic-portal absorption; and (3) individualized yoga and exercise prescription targeting muscle glucose uptake and insulin sensitization. Antidiabetic medications were systematically tapered based on glycemic response. Outcomes included HbA1c, fasting/random blood glucose, weight, BMI, abdominal girth, blood pressure, and heart rate. Treatment intensity was quantified by Panchakarma sessions completed (range 1–20). Pearson correlations and paired t-tests were used. GTT results were documented for 5 patients as a remission criterion. Results: All primary metabolic parameters improved significantly. HbA1c declined from 9.38 ± 2.10% to 7.62 ± 1.87% (Δ −1.76 ± 1.64%, p<0.001). Random blood glucose reduced from 208.3 ± 87.5 to 160.8 ± 57.3 mg/dL (Δ −47.5 mg/dL, p<0.001). Weight reduced by −3.79 ± 4.00 kg (p<0.001), BMI by −1.33 ± 1.43 kg/m² (p<0.001), and abdominal girth by −5.12 ± 5.85 cm (p<0.001) — reflecting visceral fat reduction and insulin resistance reversal. Blood pressure normalized significantly (SBP Δ −6.74 mmHg, DBP Δ −4.46 mmHg; both p<0.001). Treatment intensity correlated significantly with both HbA1c reduction (r=−0.533, p<0.001) and weight loss (r=−0.565, p<0.001), confirming a dose-dependent relationship. High-intensity treatment (15+ sessions, n=14) achieved 3-fold greater HbA1c reduction (Δ −2.72%) and 4-fold greater weight loss (Δ −9.34 kg) compared to low-intensity (1–8 sessions, n=36, Δ −0.87% HbA1c, Δ −2.31 kg). Among 78 patients with documented medication data, 51.3% achieved partial-to-complete antidiabetic drug reduction; mean reduction among those who tapered was 69.2%. Post-treatment, 43.9% achieved HbA1c <7.0% and 17.5% achieved the <6.5% remission threshold. Three of five patients with documented GTT achieved GTT Negative (normal glucose tolerance restored), representing the most stringent available evidence of T2DM remission. Conclusion: The CDC (Comprehensive Diabetic Care) program targeting insulin resistance through caloric restriction, Panchakarma-delivered botanical therapy, and exercise-based muscle conditioning achieves clinically significant glycemic improvement, dose-dependent weight reduction, antidiabetic drug tapering in over half of patients, and GTT-documented remission in a real-world urban cohort. These findings support the role of comprehensive insulin resistance reversal as a disease-modifying strategy in T2DM and provide a mechanistically coherent framework for integrating botanical therapy with established lifestyle medicine approaches.
