Food selection and appetite control is only one aspect of weight loss. The bigger part for philosophy, or to the ignorant people, willpower.
It is understanding, for some of us, it is a series of decisions, one way lies death or a fate even worse, the other way lies health or at least more healthy than the other way. The decision is the easy part, doing is not so easy.
We need to examine our will, not what we think, but what we actually do. Therein lies the problem, these are often different. We want to be rational and eat Paleoish, but then somebody is pushing some kind of "treat" or as I like to refer to it as bate, which I know contains sugar, a deadly substance. That raises a craving, a urge to have a taste, or similar feeling. Now what? We have two mutually exclusive bits of will. Cognitive dissonance what?
What I need is skills to develop more will power and carry a big stick.
My short term wants do not match with my long term 'needs'.
My needs must govern for long term life.
I need to align my short term impulsive desires with long term needs.
How does one crush our short term impulsive desires?
