The Claim
In patients with coronary artery disease undergoing cardiac rehabilitation, low-carbohydrate and low-fat diets do not result in greater reductions in 10-year cardiovascular mortality risk compared to a standard diet over a 3–4 week period, despite improvements in body composition.
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.
Among patients with coronary artery disease in cardiac rehab, switching to a low-carbohydrate or low-fat diet for 3–4 weeks does not lower the risk of dying from cardiovascular disease over the next 10 years more than a standard diet, even though body composition improves.
See the scientific wording
In patients with coronary artery disease undergoing cardiac rehabilitation, both low-carbohydrate and low-fat diets do not lead to greater reductions in 10-year cardiovascular mortality risk compared to a standard diet over 3–4 weeks, despite improvements in body composition.
Changing to a low-carb or low-fat diet for a few weeks changes body fat but does not quickly enough reduce the underlying processes that cause heart disease to kill people over ten years.
What the research says
1 studyFor heart patients in rehab, switching to low-carb or low-fat diets didn’t make them any less likely to die from heart disease in the short term than sticking to a normal healthy diet—even though they lost more body fat. So, the type of diet didn’t matter for lowering predicted heart death risk.
