Nope. Not claiming that. Try to read.
I never claimed other factors did not play a role. What I am saying is that obesity is most certainly due to laziness in a lot of cases. To deny that, is to deny reality and to be pretty much claiming that people are "ideal" and always do what is right or best.
What you said is non-lazy fat people are "outliers" - that's implies that lazyness plays a major role. You have posted nothing to support that.
Normally, unless you have a chemical imbalance, when you exercise and are active, you LOSE weight. That is just common sense. Calories in/calories out.
Read the research - it really isn't so simple.
It is that simple in very many instances. I type about these kinds of people ALL the time.
In other words, you aren't about to let the facts get in the way of your preconceptions.
