Insulin resistance, blood sugar and cholesterol

Insulin resistance sits underneath a great deal of what people come in with: weight that won’t move, energy that crashes mid-afternoon, PCOS, fatty liver, and the slide from normal blood sugar toward prediabetes and type 2 diabetes.

It’s your cells responding less well to insulin, so more insulin is needed for the same job. That can run for years before glucose rises — which is why a normal fasting glucose is not the reassurance it’s usually taken for.

The numbers worth having

Measure What it adds
HbA1c Average blood glucose over about three months
Fasting glucose One moment, and the last thing to change
Fasting insulin How hard the pancreas is working to hold that glucose
Waist measurement Abdominal fat, which is the metabolically active kind
Lipid panel Triglycerides and HDL, which move with insulin resistance
Liver function Fatty liver, which travels with this picture

Most of these are available through your GP. Your naturopath will tell you which are worth asking for and what the pattern across them means.

What genuinely shifts it

Resistance training. Muscle is where most glucose is disposed of, and building it changes insulin sensitivity more reliably than almost anything else available.

Walking after meals, which blunts the post-meal glucose rise, is free, and is one of the highest-return habits on this page.

What’s eaten with what. Protein, fibre and fat alongside carbohydrate change the curve. Order and combination do real work.

Losing abdominal fat specifically, where it’s relevant. A modest change makes a measurable difference to these markers.

Sleep, since even short-term sleep restriction measurably reduces insulin sensitivity.

Alcohol, which affects triglycerides and liver function directly.

Nutrient status, including magnesium, vitamin D and B12 where metformin is prescribed, since it depletes it.

⚠ This is shared care

Type 2 diabetes, prediabetes and lipid disorders are diagnosed and monitored medically. Don’t stop or change diabetes or cholesterol medication on the basis of anything you read — those decisions are made by the prescriber on repeat bloods.

If you have type 1 diabetes, dietary change affects insulin requirements and must be managed with your diabetes team.

Get assessed promptly for: excessive thirst and urination, unexplained weight loss, blurred vision, or wounds that won’t heal. Chest pain, breathlessness or pain spreading to the arm or jaw needs emergency assessment now.

Frequently asked questions

What is insulin resistance?

Your cells responding less well to insulin, so the pancreas makes more of it to do the same job. It can run for years before blood glucose rises, which is why a normal fasting glucose doesn't rule it out and why HbA1c, fasting insulin and waist measurement together tell you more than glucose alone.

Can a naturopath treat diabetes?

Type 2 diabetes is diagnosed and managed medically, and that doesn't change. Where naturopathic care contributes is diet, movement, weight, sleep and nutrient status — the things that genuinely influence insulin sensitivity — alongside your GP or endocrinologist and never instead of medication.

Can I stop my cholesterol medication if my diet improves?

That's a decision for whoever prescribed it, made on repeat bloods and on your overall cardiovascular risk rather than the cholesterol number alone. Don't stop it on your own. Your naturopath works alongside that conversation.
