CHAPTER 1 — WHAT TYPE 2 DIABETES ACTUALLY IS

Day 1 Chapter 1 Published: 2025-11-25

Type 2 Diabetes is not a sugar problem. It is an insulin problem. The body still produces insulin, but the cells do not respond to it correctly. This is called insulin resistance. When insulin resistance rises:

This condition can develop silently for 10–12 years before diagnosis. INSULIN: THE KEY TO UNDERSTANDING T2D Insulin is a hormone made by the pancreas. Its job is to open the receptors of cells and allow glucose to enter, removing glucose from the bloodstream. In Type 2 Diabetes, the receptors become resistant. The cells ignore insulin signal and the pancreas must produce more insulin. Early Type 2 Diabetes often shows:

WHAT IS INSULIN RESISTANCE Insulin resistance is when the body requires more insulin to achieve the same effect. The doors of the cells become harder to open. Over time, the pancreas works harder and can become fatigued. WHY TYPE 2 DIABETES DEVELOPS Lifestyle factors:

Biological factors:

Environmental factors:

Important principle: Blood sugar is the symptom. Insulin resistance is the root cause. PROGRESSION OF TYPE 2 DIABETES Stage 1 — Insulin Resistance, silent phase. Glucose is normal, insulin is high, and there are no clear symptoms. This stage is often missed because insulin is not measured. Stage 2 — Prediabetes. Fasting glucose is elevated, A1C between 5.7 and 6.4 percent, triglycerides may be rising, belly fat increases, energy is lower. This stage can last 5 to 10 years. Stage 3 — Early Type 2 Diabetes. Glucose is high, there is stress on the beta cells, fatty liver develops and inflammation increases. Symptoms are usually present here. Stage 4 — Advanced Diabetes. Insulin production begins to decline, complications start to appear, and glucose becomes harder to control. Stage 5 — Insulin dependent. The pancreas is significantly fatigued and external insulin is required. GOOD NEWS Type 2 Diabetes can be improved, reduced, reversed, controlled, and stabilised through appropriate nutrition, timing of meals, movement, sleep optimisation, stress reduction, targeted supplements, and a consistent daily routine.
