Human beings, on average, cannot exert total control over their weight. Being singularly obsessed with exerting total control over your weight is, in fact, a disordered eating behavior.
This is not the same as having an eating disorder. But it is a warning sign for developing one, and carries its own negative health effects.
It's not disordered to look at your diet and decide you'd like to drink more water, which then naturally results in you drinking less soda.
It is disordered to become obsessive about soda and feel extremely stressed at the thought of ever drinking one because of the calorie content.
There are many fitness practices that for some people, some of the time, will result in weight loss, but you don't control if it happens to you.
Because the truth no one wants to acknowledge is that losing weight isn't inherently healthy.
Gaining weight isn't inherently unhealthy.
And as you incorporate more fitness habits into your life, like movement, improved nutrition, better hydration, better rest, etc. your weight will likely regulate to your body's set weight.
Set weight is still a theory (though a well supported one) but the likelihood is your body has a genetically programmed optimum weight range. And while maintaining healthful habits you can likely toggle it to either end of your natural range, but the thinness that society idolizes is not in everybody's natural range.
Which means with fitness some people will lose weight. And some people will gain weight. Some people's weights won't change much at all.
Some people who are currently living in thin bodies may discover that they are actually healthier in fatter bodies.
Which is why weight loss centric mentalities often lead towards disordered behaviors.
Because when getting healthier doesn't make you thinner, lots of folks will choose thinness over health. And that's their choice, but we shouldn't be misrepresenting it as "healthy."
