Content: Right now, we know obesity is linked with certain diseases, most strongly type 2 diabetes, but as scientists are fond of saying, correlation does not equal causation. Maybe weight gain is an early symptom of type 2 diabetes. Maybe some underlying mechanism causes both weight gain and diabetes. Maybe weight gain causes diabetes in some people but not others. People who lose weight often see their blood sugar improve, but that’s likely an effect of calorie reduction rather than weight loss. Type 2 diabetics who have bariatric surgery go into complete remission after only seven days, long before they lose much weight, because they’re eating only a few hundred calories a day.

Disease is also attributed to what we eat (or don’t), and here, too, the connections are often assumed to relate to weight. For instance, eating fast food once a week has been linked to high blood pressure, especially for teens. And eating fruits and vegetables every day is associated with lower risk of heart disease. But it’s a mistake to simply assume weight is the mechanism linking food and disease.
