The Claim
Transitioning from metabolically healthy normal weight to metabolically healthy overweight or obesity is associated with a 159% higher risk of stroke but not heart disease.
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.
People who move from a normal weight to overweight or obese without metabolic dysfunction have a 159% higher risk of stroke but not heart disease.
See the scientific wording
Transitioning from metabolically healthy normal weight to metabolically healthy overweight or obesity is associated with a 159% higher risk of stroke but not heart disease, indicating that weight gain without metabolic dysfunction may specifically elevate stroke risk.
When fat tissue grows without metabolic dysfunction, it releases substances that stiffen blood vessels in the brain and make blood more likely to clot, increasing the chance of a stroke.
What the research says
1 studyPeople over 50 who gain weight but keep their blood pressure, sugar, and cholesterol normal still have more than double the risk of having a stroke — but not a heart attack — compared to those who stay at a normal weight and metabolically healthy.
