The Claim

For each kilogram of weight lost, systolic blood pressure decreases by 1.05 mm Hg and diastolic blood pressure decreases by 0.92 mm Hg in adults.

Support is ahead, but a single strong opposing study can change this.

In plain English

When adults lose one kilogram of body weight, their systolic blood pressure drops by 1.05 mm Hg and their diastolic blood pressure drops by 0.92 mm Hg.

See the scientific wording

For each kilogram of weight lost, systolic blood pressure decreases by 1.05 mm Hg and diastolic blood pressure decreases by 0.92 mm Hg, indicating a consistent, dose-dependent relationship between weight reduction and blood pressure lowering in adults.

Why this might work

When a person loses weight, fat tissue shrinks, which reduces signals that overstimulate the kidneys to hold onto salt and water and tighten blood vessels. This causes less fluid in the bloodstream and lower pressure in the arteries.

  1. Study: Influence of Weight Reduction on Blood Pressure: A Meta-Analysis of Randomized Controlled Trials

    Losing each kilogram of weight lowers blood pressure by about 1 point systolic and less than 1 point diastolic — and this study proves it by looking at many people who lost weight. The more you lose, the more your blood pressure drops.
