Why visceral fat matters

The fat around your organs is the one that hurts you — and the first to respond.

Key points

• Visceral fat sits around your liver, gut and heart. Unlike fat under the skin, it's metabolically active and drives inflammation and insulin resistance.
• It's strongly linked to type 2 diabetes, heart disease, fatty liver and some cancers — even in people with a “normal” weight.
• The best home measure is waist-to-height ratio: keep your waist under half your height (ratio below 0.5).
• Good news: visceral fat is usually the first to shrink when you create an energy deficit — fasting makes that deficit easier to sustain.
• Measure your waist weekly at the navel, relaxed, after breathing out. Trends matter more than a single reading.
