"I wanted to share how this approach has been life changing for me. For as long as I can remember I struggled with what you could say mild eating disorders — mainly by restricting my diet to achieve weight loss goals. But tracking blood glucose as an approach has freed me from all of those previous habits and obsessions. I can feel my hunger so clearly now — I know when my body really needs to eat. I have lost weight as a result, yes, but this looks totally different than what my weight loss results looked like before. Best of all, I don't fuss with food anymore, which is very liberating. I know when my body needs fuel and when it does not. I wanted to share with everyone my story — and especially Craig — this is life changing. So thank you."

Is cortisol quietly wrecking your blood sugar?

Cortisol is your body's main stress hormone — and one of its core jobs is to raise blood sugar, by signalling your liver to dump stored glucose into your bloodstream and by making your cells more resistant to insulin. That's useful in a real emergency. The problem is chronic stress keeps cortisol elevated for months or years, which means blood sugar keeps getting pushed up long after the "emergency" has passed.

This is why so many people with stubborn fasting glucose, insulin resistance, or midsection weight gain never find the answer in their diet alone — the driver is upstream, in a dysregulated stress-hormone rhythm.

25 questions · scored instantly

Rate each statement 0 (never) to 3 (almost always), based on the last few weeks — not how you wish you felt. At the end you'll see your score, a risk band, and which specific area (sleep, energy, cravings, mood, and more) is driving it.

Optional

Waist-to-height ratio check

Measure your bare waist at belly-button level, after exhaling. This ratio scales to your own frame — same thresholds for everyone — and doesn't add to your score above.

Height (cm)

Waist circumference (cm)

0/60

Worth knowing: these symptoms overlap with thyroid issues, depression, sleep apnea, and hormonal shifts like perimenopause or andropause. A high score is a prompt to get tested — ideally a 4-point saliva cortisol test or a DUTCH test — not a diagnosis on its own.

Why this matters

Your metabolic age is the number your doctor never tells you.

A standard blood panel checks one or two markers and tells you if you're "normal." Normal is not the same as optimal. And normal is not the same as the 12% — the fraction of adults who have all five metabolic markers in the genuinely healthy range simultaneously.

Your metabolic age is calculated from those five markers. It tells you whether your biology is younger or older than your birth certificate — and exactly which numbers to change to move it lower.

Chronological age 45 years old
Metabolic age 58 years old
+13 years older than the calendar.
Every marker that improves takes years back.
📏
Where you carry weight matters as much as how much
Waist-to-hip and waist-to-height ratios reveal visceral fat risk that the scale and BMI both miss entirely.
0.90
WHO risk threshold for waist-to-hip ratio in men (0.85 in women)
📊
88% of adults are metabolically unhealthy
Only 12% have all five markers optimal simultaneously. Most people in that 88% feel fine — until they don't.
88%
of adults have at least one marker out of optimal range (NHANES data)
⏱️
Metabolic age is reversible
Every marker that improves subtracts years from your metabolic age. Members routinely reverse 8–14 years within 4–6 months.

"Over the past couple of years I have been struggling to keep my blood sugar within an acceptable range and I was close to having to take medication to correct the issue, or risk getting Type 2 Diabetes. However, after consulting with Craig and following his detailed advice I have now been able to bring my blood sugars within the normal range, with 4 months. Craig is very calm and patient and has a considered friendly approach. Unlike other Nutritionists, his advice is based on Scientific research and evidence, that produce results."

How the calculator works

The basis for your metabolic age

The metabolic age calculation is built on published research linking each of the five metabolic markers to biological ageing rates. It is not a simple average — each marker has a specific penalty curve calibrated to the clinical thresholds at which biological age acceleration is measurably documented.

The sources the calculator draws from include:

Fasting glucose & HbA1c → biological age acceleration
Levine et al. (2018) — phenotypic age model based on clinical biomarkers including glucose. Aging, 10(4).
Fasting insulin & HOMA-IR → insulin resistance ageing
Matthews et al. (1985) — HOMA model. Insulin resistance is independently associated with accelerated biological ageing across multiple organ systems.
TG:HDL ratio → cardiovascular age & metabolic risk
McLaughlin et al. (2005) — TG:HDL as the most accurate predictor of insulin resistance in a lipid panel. American Journal of Cardiology.
Blood pressure → vascular age
Wills et al. — arterial stiffness and vascular age modelling. Each 10 mmHg increase above 120 systolic independently predicts cardiovascular event risk.
Waist circumference → visceral fat & metabolic age
Carnethon et al. — waist circumference as a stronger predictor of metabolic age acceleration than BMI across all age groups.
Waist-to-hip ratio → central fat distribution
World Health Organization (2008) — waist-to-hip ratio report. A ratio above 0.90 (men) or 0.85 (women) is classified as substantially increased metabolic risk.
Waist-to-height ratio → whole-population risk screening
Ashwell & Gibson — "keep your waist to less than half your height" as a simple boundary value that predicts risk consistently across sexes, ages, and ethnicities.
Neck circumference → upper-body fat & metabolic syndrome
Multiple population studies converge on ≈37–38 cm (men) and ≈33–34 cm (women) as the threshold linked to significantly increased metabolic syndrome risk.
Resting heart rate → cardiovascular & all-cause mortality
Large cohort studies (Whitehall, Framingham, NHANES) consistently show rising mortality risk above 70 bpm, with the sharpest increase at ≥80 bpm.

Important: The metabolic age shown is an evidence-based estimate, not a clinical diagnosis. It is designed to give you a meaningful, actionable number — not a medical result. Use it as a direction indicator and motivation tool. For clinical assessment, use the result alongside a full blood panel reviewed by your doctor.

The studies behind the numbers

What each test is, and why it's in here

A quick reference for every marker the calculator uses — what it measures, and the research behind why it matters.

Fasting blood sugar — core marker

A snapshot of glucose in your blood after an 8-hour fast. It's one of the five NHANES-defined criteria for metabolic health and the most direct measure of how well your body is managing sugar right now.

HDL cholesterol — core marker

"Good" cholesterol that helps clear excess fat from the bloodstream. Low HDL is one of the five official metabolic syndrome criteria and tracks closely with cardiovascular risk.

Triglycerides — core marker

Fat circulating in your blood, driven almost entirely by carbohydrate and alcohol intake. One of the five core metabolic health criteria, and one of the fastest markers to respond to dietary change.

Blood pressure — core marker

The force of blood against your artery walls. Elevated blood pressure is one of the five core metabolic health criteria and a direct measure of cardiovascular strain.

Waist circumference — core marker

A proxy for visceral fat — the fat packed around your organs. It's the fifth core metabolic health criterion and, unlike BMI, tells you where fat is stored, not just how much you carry.

HbA1c — optional upgrade

A 90-day average of your blood sugar, built from how much glucose has stuck to your red blood cells. It reveals the pattern fasting glucose alone misses, including post-meal spikes.

Fasting insulin — optional upgrade

The earliest measurable sign of insulin resistance — it rises years before fasting glucose does. Rarely included on a standard panel, yet widely considered the single most predictive marker of metabolic decline.

HS-CRP — optional upgrade

High-sensitivity C-reactive protein measures systemic inflammation — a silent driver of heart disease and accelerated ageing. A low reading is one of the clearest signs your body isn't under chronic stress.

Waist-to-hip ratio — optional upgrade

Waist divided by hip circumference. It captures fat distribution rather than just total fat — the WHO classifies a ratio above 0.90 (men) or 0.85 (women) as substantially increased metabolic risk.

Waist-to-height ratio — optional upgrade

Waist divided by height. The simplest whole-population risk screen there is — keeping your waist under half your height is linked to lower metabolic risk across virtually every body type and ethnicity studied.

Neck circumference — optional upgrade

A simple tape-measure proxy for upper-body fat. Multiple population studies link a larger neck to significantly increased metabolic syndrome risk, independent of waist size.

Resting heart rate — optional upgrade

Your heart rate at rest. Large cohort studies consistently link resting rates above 80 bpm to higher cardiovascular and all-cause mortality risk, independent of other risk factors.
