Obesity's Contribution to Diabetes Risk: Excess body fat, especially around the abdomen, significantly elevates the risk of Type 2 diabetes. This adipose tissue disrupts normal metabolic processes, causing
insulin resistance. In this condition, cells in the muscles, fat, and liver become less responsive to insulin.
- Inflammatory substances (cytokines like TNF-alpha and IL-6) released by fat cells interfere with insulin signaling.
- Elevated free fatty acids from fat metabolism hinder insulin's effectiveness.
- The pancreas initially overcompensates by producing more insulin, but eventually cannot keep up, leading to hyperglycemia.
- Insulin resistance prevents glucose from entering cells, causing it to accumulate in the blood.
Achieving and maintaining a healthy weight through appropriate diet and regular exercise can mitigate insulin resistance and lower diabetes incidence.
