Christy Harrison on the “fat and fit” study

Until weight science can control for weight cycling and weight stigma, we can’t say that being at the higher end of the BMI spectrum causes any health conditions—even if higher weights are associated with these health conditions. Correlation does not equal causation, y’all.

Moreover, *even if* weight did have some causal effect on people’s health (which is possible, but again we can’t actually know until we control for weight stigma and weight cycling), we DON’T HAVE a known way for more than a tiny fraction of people to lose weight and keep it off permanently.

The success rate of intentional weight-loss efforts is 5% or less, by most researchers’ accounts. So for 95% or more of people, ALL diets are yo-yo diets.
