You can tell a lot about a person's health by how their body looks. The proof is in the pudding.
If you look unhealthy, then I will not trust your "science"

Works 95% of the time, agreed. Sometimes it doesn’t. But the FA types would have you believe it doesn’t work 99% of the time.
That’s a good evolutionary reason we can often glance at someone and tell how healthy they are, and why so many spend time often poorly attempting to send those same signals artificially. Convincing yourself that you can be healthy and 300 pounds is just a PsyOp against yourself.
