Insulin Resistance — In Plain English
Insulin resistance happens when your cells stop responding efficiently to insulin. The result? Higher blood sugar, higher insulin levels, and a metabolism that feels harder to manage.
First: What does insulin do?
Insulin is a hormone that helps move glucose (sugar) from your bloodstream into your cells, where it can be used for energy.
Think of insulin as a key. It unlocks your cells so glucose can enter.
When resistance develops
Over time, if insulin is constantly elevated, your cells can become less responsive. The “key” doesn’t work as smoothly — so your body produces more insulin to compensate.
Why it matters
- Higher fasting glucose
- Higher A1C over time
- Increased fat storage (especially around the waist)
- Energy crashes and cravings
- Greater long-term risk for type 2 diabetes
What contributes to insulin resistance?
- Frequent high refined carbohydrate intake
- Chronic stress and elevated cortisol
- Poor sleep
- Low muscle mass
- Low physical activity
Good news: it’s reversible
Insulin resistance is not a life sentence. The body adapts in both directions.
Three practical starting points
- Prioritize protein at meals.
- Strength train 2–3 times per week.
- Walk after meals when possible.
The goal is not perfection. The goal is to create a steadier environment inside your body so glucose handling improves over time.
