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.
If you have excess body fat, especially around your midsection, your risk for heart disease, heart failure, and arrhythmias increases significantly, even if your blood pressure and cholesterol are normal. Do not rely on BMI alone; ask your doctor about assessing visceral fat or using waist circumference, as these are better predictors of heart risk.
Obesity is a major risk factor for the development of HF... The incidence of HF increases along the BMI spectrum... individuals who are obese have a significantly greater risk of incidence coronary artery disease (CAD)... obesity accounts for 20% of AF cases... Obesity is also an recognized risk factor for sudden cardiac death (SCD)... the risk of SCD increases by 16% for every 5-unit increment in BMI

More from this paper
- 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.Good
- 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

- 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
