Structured weight reduction combined with intensive cardiometabolic risk factor management significantly reduces atrial fibrillation symptom burden, severity, and arrhythmia duration compared to general lifestyle advice alone in overweight/obese patients.
For patients with atrial fibrillation and obesity, a structured weight loss program that includes a short period of very-low-calorie dieting followed by lifestyle maintenance, combined with aggressive management of blood pressure and cholesterol, significantly reduces AF symptoms and arrhythmia duration compared to standard advice alone.
The intervention group showed a significantly greater reduction, compared with the control group, in weight (14.3 and 3.6 kg, respectively; P < .001) and in atrial fibrillation symptom burden scores (11.8 and 2.6 points, P < .001), symptom severity scores (8.4 and 1.7 points, P < .001)... and cumulative duration (692-minute decline and 419-minute increase, P = .002).
Why this rating
Randomized controlled trial with blinded outcome assessment and statistically significant results (P < .001).

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
