Losing the weight is all about making what you intend…be what you get?
If you are to pull this off, you have to make some hard choices. What is dominant for you—overeating, eating junk, popping down those calories—probably requires little mental effort at this point. It just “comes naturally” to you. You eat like this and ignore your desire to lose the weight.
Making the hard choices means upping your mental effort and getting away from having it easy.
Why is getting yourself to do this and to stop doing that so hard? One reason may be that you don’t think you have real options. You’re stuck in the familiar, in the mentally easy, and the only way out, you think, is too hard for you.
How can you give yourself the real option of getting what you intend? You could make a list of options, go over them, choose which one you want to focus on. Then pay careful attention to the option you select. Keep it in mind as much as possible. Don’t let it get lost or bedraggled or muted by anything else in your life. It should be that important. If it is "always" on your mind, then you will think of it as a real option.
Having options, knowing them, selecting them, keeping them in mind. This is what makes the options real, and having real options means making the hard choices will be more comfortable for you.
