Visceral Fat Risk Check? What a Quick Waist Check Shows
A rough guide to your waist, not a visceral fat test.

The question
What does the quick middle check do?
Short answer
The quick middle check gives you your waist-to-height result, the easy wins already in your day, and the first one to start today. No email. Your answers stay on your phone. It is a rough guide, not a visceral fat test. Only a scan, like an MRI or DEXA, measures visceral fat.
Midline cannot measure visceral fat and is not medical advice. Check with a doctor before making medical decisions.
We can't promise a result. Healthy weight loss is slow and varies from person to person. Your waist is a rough guide, not a scan.
What does the check do?
You can use a tape, or the string test if you have no tape.
The tape path gives your waist-to-height ratio. One simple rule is to keep your waist under half your height.
Then it shows the easy wins already in your day, and the first one to start today.
What does it not do?
A tape can't see visceral fat. Two people with the same waist can carry very different amounts inside. Only a scan, like an MRI or DEXA, measures it. Midline can't measure it.
A rough guide, not a diagnosis.
If your result worries you, talk to your doctor.
What do you need before you start?
A tape and your height, or a piece of string. The steps for both are on checking your waist at home.
Wrap the tape around the widest part of your belly, standing relaxed. Use the same spot each time.
If measuring your body makes you anxious, or you've had an eating disorder, skip it and talk to your doctor instead.
What happens after the check?
You pick a first habit. Midline puts it on a daily schedule, with a tick for each, and your supplements at the right times. The habits experts recommend are on the visceral fat guide.
The daily schedule is a paid plan: 14 days free with no card, then $59.99 a year or $9.99 a month.
Frequently asked questions
Does the check measure my visceral fat?
No. A tape can't see visceral fat. Only a scan, like an MRI or DEXA, measures it. Midline can't measure it.
How long does the check take?
A few minutes.
Do I need to give my email?
No. The check asks for no email, and your answers stay on your phone.
Is the result a diagnosis?
A rough guide, not a diagnosis. If your result worries you, talk to your doctor.
What if I have no tape?
No tape? Cut a piece of string as long as you are tall and fold it in half. Wrap it around the widest part of your belly. If the ends overlap, your waist is under half your height. If they don't overlap, it's half your height or more.
