Figure 2:

Weight loss goal as percent of current weight, by age. (A): Without stratification by BMI. We find a U-shaped curve in agreement with existing literature. The U is significantly deeper for women than for men. (B): With this stratification (results shown only for women), we now see that younger adults set the most ambitious goals, but get less ambitious up until the age of 30, from which point goals stay relatively consistent. Then, around 60, older adults set increasingly less ambitious goals. Error bars in all plots correspond to bootstrapped 95% confidence intervals (here, they are mostly too small to be visible).
