Higher peak aerobic power (VO2peak) is the primary predictor of long-term survival in men with coronary heart disease, with each 1 mL/kg/min increase reducing mortality risk by 9%.
For men with heart disease, improving aerobic fitness is the single most effective way to extend life. You don't need elite fitness; even small gains in VO2 (measured by how much oxygen you use during peak exercise) significantly lower your risk of dying. Focus on supervised cardiac rehabilitation to safely build this capacity.
a 1-mL/kg per minute increment in V˙ O2peak could be equated with a 9% improvement in prognosis (hazard ratio, 0.91)... the primary factor influencing prognosis in coronary heart disease patients is the individual’s effort tolerance, as assessed objectively by the measurement of V˙ O2peak.

- 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
