Even doctors can be fooled by assumptions, as in treatments that do not have a proper scientific basis but are used on patients anyway.
This same kind of fact-blindness is at work when we are told that to lose weight, we must "eat less and move more." And we do. And it doesn't work.
I'm saying this as someone who successfully mastered it. For my body, it took an hour and a half a day of structured exercise (and this is all on the machines, no prep or commute time.) It took eating every two or three hours, of foods that made me hungry, like salad with no fat dressing.
This was a very difficult plan. This is the best they can do?
I felt I had damaged my body with my binge eating and malnutrition from my periodic starve cycles which followed. I ate all the healthy foods like whole grain bread and low fat yogurt and rice cakes. I did a lot of cardio.
This, ironically, was the exact wrong thing to do.
When I couldn't exercise at that pace anymore; that whole way of eating worked against me.
Yet, it was still the only one they offered.
I did not regain my health and slimness until I was willing to admit there must be something wrong with the expert's advice. So I went against their advice, and it worked out well.
Or, I'm a mutant. Except; I'm not the only one.
