The Claim

In patients with coronary artery disease undergoing cardiac rehabilitation, the low-fat diet results in more stable body composition changes over 6 months compared to the low-carbohydrate diet.

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.

Comparative
1 study reviewed
In plain English

Among patients with coronary artery disease in cardiac rehabilitation, those following a low-fat diet maintain more consistent changes in body composition over six months than those following a low-carbohydrate diet.

See the scientific wording

In patients with coronary artery disease undergoing cardiac rehabilitation, the benefits of low-carbohydrate and low-fat diets on body composition are more stable over 6 months in the low-fat group compared to the low-carb group, suggesting differential long-term sustainability.

Why this might work

Eating less fat reduces signals that make you feel hungry, so you eat fewer calories over time. Your body keeps burning fat for energy instead of switching to burning sugar, which helps you hold onto weight loss longer.

  1. Study: Biomarker-based risk assessment of dietary intervention in patients with coronary artery disease during cardiac rehabilitation—a quasi-experimental study

    People with heart disease who followed a low-fat diet after rehab kept their body fat lower over six months better than those on a low-carb diet, whose body fat started creeping back up—likely because it was harder for them to stick to the low-carb plan.
