A 3-Year Randomized Trial of Lifestyle Intervention for Cardiovascular Risk Reduction in the Primary Care Setting: The Swedish Björknäs Study
The study showed that eating better and exercising more improved some health markers, but it didn't track whether people had fewer heart attacks or strokes — which is what the claim is really about.
The study looked at how a strict diet and exercise plan affected cholesterol and weight, not whether people had fewer heart attacks. So while it showed some health improvements, it didn’t prove the plan works as well as statins at preventing real heart problems.
This study found that for some people with diabetes, losing weight through diet and exercise lowered heart attack risk — but for others, it didn’t help or even made things worse. So saying it always cuts heart risk by 20–40% like statins do is not true.
