What's your waist-to-height ratio?™
One number — your waist measured against your height — tells you more about your metabolic health than the bathroom scale ever will. All you need is a tape measure.
Check your number
This is a general wellness marker, not a medical diagnosis of any condition. Share your number with your doctor, and keep tracking your A1C and bloodwork together.
Your waist is part of the same story as your labs
If your blood sugar average (A1C) has been creeping up, that's usually insulin resistance at work — your body pumping out more and more insulin to keep up. And insulin is a fat-storage hormone: the higher it runs, the more fat it packs deep in your belly, and the less it lets you burn. That's why your waist is part of the same story as your labs.
It's also why your middle may never have responded, no matter how carefully you ate — this was never a willpower problem. It's a hormone problem, and it shows up in the one number you just checked: your waist-to-height ratio.
You're focused on one number.
Here's the one you can control.
Your A1C (90-day blood sugar average) and your waistline aren't two separate problems — they're two readings of the same metabolic issue. The visceral fat your waist measures is what drives insulin resistance, and insulin resistance is what pushes blood sugar (glucose) — and your A1C — up. Your doctor tracks the blood. Your tape measure tracks the root cause — and study after study shows it's the leading indicator, the warning that shows up before your A1C does.1,2 Your waist is the number you can move with lifestyle — and monitor on your own. That's what taking control looks like.
Your A1C
From your bloodwork. Read in a lab every few months. It belongs with you and your doctor — and it's theirs to interpret.
Your waist-to-height ratio
Measured at home with a tape measure — no lab, no appointment, no waiting months between readings. You can check it any morning and watch it respond to what you're doing. And when it moves, you won't need the tape to notice. Linked to insulin resistance and greater diabetes risk,1,2 it's the number the whole Reset is built around.
1 Waist-to-height ratio showed the strongest association with insulin resistance among 2,231 adults (Scientific Reports, 2021). 2 Waist-to-height ratio was the strongest anthropometric predictor of type 2 diabetes among 161,127 adults in the UK Biobank (2023).
Why your waist-to-height ratio matters so much to your metabolic health
Your A1C is the blood-sugar number your doctor watches — keep tracking it together. But it isn't the only window into your metabolic health. There's a second one you can check at home, today: where your body carries fat.
The fat that matters is hidden
The fat that drives metabolic risk isn't the kind you can pinch. It's visceral fat — packed deep around your organs, behind your abdominal wall. You can carry a lot of it and still look "not that big."
It's metabolically active
Visceral fat doesn't just sit there. Research links it directly to insulin resistance and inflammation — the same metabolic strain an elevated A1C reflects. It's closely tied to rising blood sugar and blood pressure, and it shows up first at your waistline.
Why not the scale — or BMI?
Two people can weigh exactly the same and carry it in completely different places. The scale can't see where fat sits, and neither can BMI. Waist-to-height can — which is why health researchers have moved toward it. In study after study, it flags cardiometabolic risk better than BMI.
Why 0.5?
Your waist measured against your height is a simple, validated proxy for how much visceral fat you carry. The researchers' rule of thumb, used by health authorities for public-health guidance: keep your waist under half your height. One threshold, every height, checked with a $2 tape measure (or a piece of string).

General education, not medical advice. Talk with your doctor about your own numbers and what they mean for you.
The number moves when the fat behind it does
Waist-to-height ratio tracks deep belly fat — and deep belly fat responds to how you eat. That's why the tape measure moves in weeks, while lab work takes months to catch up.
If your number is above 0.5, the fix isn't willpower, and it isn't another app. It's food.
