🔥 One of the most important health markers most doctors don’t routinely test… is fasting insulin.
Most labs say fasting insulin is “normal” anywhere up to about 25.
But many metabolic health researchers prefer to see it much lower, closer to 2–6 for optimal metabolic health.
Why does that matter?
Because insulin resistance can develop years even decades before blood sugar rises.
You can still have:
✔ Normal glucose
✔ Normal A1C
✔ But elevated insulin
And elevated insulin is often one of the earliest warning signs of metabolic dysfunction.
Here’s how many metabolic researchers interpret fasting insulin levels:
✅ 2–6 → Optimal metabolic health
⚠ 6–8 → Early insulin resistance may be developing
⚠ 8–12 → Moderate insulin resistance
⚠ 12–20 → Significant insulin resistance
🚨 20+ → Severe hyperinsulinemia
The encouraging part?
Insulin sensitivity can improve.
Things that help lower insulin resistance include:
🥦 Eating whole, nutrient-dense foods
🍗 Getting adequate protein
🚶 Moving your body regularly
😴 Prioritizing sleep
🔥 Lowering chronic inflammation
Another piece many people overlook is omega balance.
Today’s diet tends to be very high in omega-6 fats and low in omega-3s, which can promote inflammation and worsen metabolic health.
That’s one reason I personally work on improving my omega-6 : omega-3 ratio and why I use Balance Oil as part of my daily routine. It helps support that balance while providing important EPA and DHA omega-3s.
Small daily habits can have big long-term effects on metabolic health.
