What is insulin resistance?

Short answer
Insulin resistance means your cells respond less efficiently to insulin, so the pancreas often releases more insulin to keep blood sugar in range. It can exist for years before A1C rises into prediabetes or diabetes. It is closely tied to excess visceral fat, weight gain, cravings, and cardiometabolic risk—and it usually improves with sustained weight loss, activity, sleep, and clinician-guided care when needed.
Detailed answer
Insulin resistance is not the same as type 2 diabetes, though it is a major pathway toward it. Standard screening uses fasting glucose, A1C, or an oral glucose tolerance test; fasting insulin or HOMA-IR can add context but are not routine on every panel and vary by lab.
Weight loss of roughly 5–7% of body weight—combined with regular movement—has strong trial evidence for improving insulin sensitivity and lowering diabetes risk in high-risk adults (Diabetes Prevention Program).
If you have waist gain, post-meal fatigue, strong carb cravings, or “food noise,” discuss metabolic labs and a structured plan with a clinician rather than relying on normal A1C alone.
