What if?
What if we could fix our production systems so they could provide crops that meet the nutrition and consumer preferences of our global population?
Health impacts
Obesity takes a greater toll on wellbeing for young people. Our projections suggest that a 15-year-old male who experiences obesity (BMI between 35 and 40 kg/m2) could gain 8-11% wellbeing (0.08 to 0.11 WALYs) if he reduced his weight to a healthy level, whereas a male adult (age 40+) would only benefit from a weight loss if he has a BMI greater than 40. Similarly, a 15-year-old woman who experiences obesity could gain 0.12 WALYs with a healthy weight reduction, while women older than 40 would gain 0.04 WALYs from a healthy weight reduction.

Community impacts
Individuals who live with a partner who has a healthy BMI should experience no loss of wellbeing, according to our predictions. However, at a BMI of 30, partners lose 0.03 WALYs on average; at a BMI 40, the loss doubles to 0.06 WALYs; and at BMI 45, partners lose 0.11 WALYs on average.
