Being underweight in young adulthood is associated with an increased risk of intracerebral and subarachoid hemorrhage (stroke types), whereas obesity is associated with increased risk of coronary heart disease and intracerebral infarction.
Maintain a healthy body weight range. While obesity is a known risk for heart disease and ischemic stroke, being underweight in young adulthood is also a risk factor for hemorrhagic stroke. Aim for a balanced weight rather than extreme leanness.
Body mass index (BMI, kg/m2) showed increased risk with CHD and intracerebral infarction, whereas for intracerebral and subarachoid haemorrhage both under- and overweight was associated with increased risk.
Why this rating
Large cohort study with sufficient power to detect type-specific stroke risks.

- Higher muscle strength (specifically grip and knee extension) in young adulthood is independently associated with a lower incidence of coronary heart disease and stroke later in life, even after adjusting for body mass index, blood pressure, and socioeconomic status.Strong
- Greater height in young adulthood is inversely associated with the incidence of coronary heart disease and all types of stroke.Strong

- 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
