Intentional weight loss of 10% or more significantly improves cardiovascular outcomes, including arrhythmic free survival and symptom severity in atrial fibrillation, whereas lesser degrees of weight loss (e.g., 5%) do not show the same benefit.
If you have Atrial Fibrillation and are overweight, aim for a weight loss of at least 10% of your body weight. Small losses (like 5%) may not be enough to significantly improve your heart rhythm or symptoms. Consult your doctor for a structured weight loss plan.
GoodQualifiesHIGH confidence
Sufficient weight loss ((cid:1)10%) carries significant benefit in terms of arrhythmic free survival rate, AF burden, and symptom severity... However, this benefit is not observed with lesser degrees of weight loss (5% weight loss)

- Obesity is a major independent risk factor for the development of coronary artery disease, heart failure, atrial fibrillation, and sudden cardiac death, with risk increasing linearly with BMI and visceral adiposity.Strong
- The 'obesity paradox' in heart failure—where overweight/obese patients have better short-term outcomes than normal-weight patients—is likely confounded by unintentional weight loss from underlying diseases (like cancer) and lead-time bias, rather than being a true protective effect of obesity.Good
