Higher BMI (overweight, obesity, and morbid obesity) is associated with a significantly increased lifetime risk of incident cardiovascular disease and a greater proportion of life lived with cardiovascular morbidity compared to normal BMI, despite similar or slightly higher all-cause longevity in the overweight group.
Maintaining a normal BMI (18.5-24.9) is associated with the lowest lifetime risk of developing cardiovascular disease and the most years lived free of heart conditions. While being overweight might not shorten your total lifespan as much as obesity, it significantly increases the number of years you will spend living with cardiovascular disease, reducing your quality of life and increasing healthcare burdens.
In this study, obesity was associated with shorter longevity and significantly increased risk of cardiovascular morbidity and mortality compared with normal BMI. Despite similar longevity compared with normal BMI, overweight was associated with significantly increased risk of developing CVD at an earlier age, resulting in a greater proportion of life lived with CVD morbidity.
Why this rating
Large-scale pooled cohort study (190,672 participants) with long-term follow-up and direct measurement of BMI and CVD events.

- 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
