What is HOMA-IR?
HOMA-IR is a calculated insulin resistance index. The formula is straightforward:
(fasting insulin μIU/mL × fasting glucose mmol/L) ÷ 22.5
It shows how well your cells respond to insulin.
Why does this matter for weight?
When your cells stop responding to insulin properly, the pancreas starts producing more and more of it. And high insulin is essentially a command to your body: store fat and don't release it, even when you're in a calorie deficit.
This is exactly why a frustrating paradox occurs: you eat less, but the weight doesn't budge. Intense sugar cravings and sudden drowsiness after lunch come from the same place.
The impact on women's health
In women, insulin resistance disrupts the balance of estrogen and progesterone, which worsens PMS, throws off the menstrual cycle, and promotes fat accumulation around the abdomen and hips.
How to actually interpret HOMA-IR
Standard lab results often simply state 0–2.7 NORMAL. But here's how it actually matters:
- > 2.5 — clinical threshold for insulin resistance. This is the cutoff used in diagnosis, and numbers like these are a reason to work with a doctor and a nutritionist.
- 1.5–2.5 — not a diagnosis, but a signal. If you also have contributing factors (abdominal fat, poor sleep, sugar cravings after meals), this is the zone where it's already worth changing your diet rather than waiting until you hit 2.5.
- < 1.5 — the functional optimum in preventive medicine. This is the target if you want a well-functioning metabolism.
What can be done?
In my support programs, we successfully adjust lifestyle habits to reduce insulin resistance, make weight loss easier, and restore stable energy throughout the day. Book an express diagnostic session and ask your questions.
