By the way, study after study has shown a u shaped life expectancy vs bmi, with peak life expectancy at bmi around 28. Higher BMI around 30 is even better if you have a chronic illness like heart disease, diabetes, lung disease, cancer etc. this is true even for Asian populations where average bmi is 22. “Normal” is actually worse for life expectancy, “overweight” is ideal, and obese and underweight are both bad.
