The Claim
A reduction of one kilogram of body weight is associated with a decrease of approximately 1 mm Hg in systolic blood pressure.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Losing one kilogram of body weight lowers systolic blood pressure by about 1 mm Hg.
See the scientific wording
Each kilogram of body weight loss reduces systolic blood pressure by approximately 1 mm Hg.
When body weight drops, fat tissue shrinks, which turns down signals that make blood vessels tighten and the kidneys hold onto salt and water. This lowers the pressure inside the blood vessels.
What the research says
4 studiesLosing weight usually lowers blood pressure, and this study showed people lost about 5.5 kg using a web program — so it supports the idea that losing weight can help lower blood pressure, even though it didn't measure blood pressure directly.
Study: Long-term effects of weight-reducing drugs in people with hypertension.
The study found that when people lost 1 kilogram of weight, their systolic blood pressure went down by about 1 mm Hg — exactly what the claim says.
When people lost weight using special pills, their blood pressure also went down — and since they lost about 8.7 kg, it’s very likely that each kg lost helped lower their blood pressure by roughly 1 point, just like the claim says.
Study: Influence of Weight Reduction on Blood Pressure: A Meta-Analysis of Randomized Controlled Trials
Losing one kilogram of body weight lowers blood pressure by about 1 point, and this study found it’s actually 1.05 points — so the claim is basically right.
