Visceral Fat: What It Is and Which Habits Experts Recommend

What is visceral fat?

Visceral fat is fat deep inside your belly, around your organs. Experts link a lot of it to insulin resistance and type 2 diabetes.

That is an association. It does not show that visceral fat causes those conditions.

Why does it matter?

Try to keep your waist under half your height. That's a waist-to-height ratio under 0.5.

That is why a waist check is worth a minute. It is a place to start, and nothing more.

How do you check your waist?

Wrap the tape around the widest part of your belly, standing relaxed. Use the same spot each time.

Try to keep your waist under half your height. That's a waist-to-height ratio under 0.5.

The full steps, and the string test for when you have no tape, are on checking your waist at home. If you would rather have the result worked out for you, use the free waist-to-height calculator or the quick middle check.

If measuring your body makes you anxious, or you've had an eating disorder, skip it and talk to your doctor instead.

Why is a tape a rough guide, not a scan?

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.

Which habits do the experts back?

Result claims here belong to the habit and its sources, not to Midline.

Midline has not been tested in a trial.

If you drink heavily every day, talk to your doctor before you cut back.

If you haven't been active for a while, or you have a heart, joint or blood pressure condition, speak to your doctor first.

What don't the experts back, or disagree on?

• You can't target fat in one spot by exercising it. Targeting belly fat means targeting body fat overall.
• Eating windows on their own have mixed evidence for weight. In a 12-month trial, adding an 8 am to 4 pm window to calorie cutting made no significant difference.
• Supplements sold to fix your gut and speed up weight loss do too little to matter. Habits come first.

Supplements still have a place in a routine, at the right times. See best time to take supplements.

If you take insulin or another diabetes medicine, are pregnant, or have had an eating disorder, don't set food rules without your doctor.

What about weight and feeling better?

Food, movement, sleep, alcohol and stress all affect visceral fat. Start small and add one change at a time.

• Walking is the easiest way to move more. For weight, what you eat matters more than exercise.
• Short sleep turns up your appetite, and the waistline tends to grow. Dieting on too little sleep means more of the weight you lose comes from muscle.
• Exercise gives you more energy and lifts your mood.
• Good sleep supports your mood.

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.

If you take a weight-loss medicine such as a GLP-1, metformin or another diabetes medicine, or blood pressure medicine, talk to your prescriber before changing how you eat or move. Some of these medicines need a dose change when habits change.

Where does Midline fit?

Midline puts these habits, and your supplements at the right times, on one daily schedule, with a tick for each. It can't measure visceral fat.

Start with the quick middle check. It is a rough guide to your waist, so you know where you are before you pick the first habit.
