Keep reminding yourself of your “why”.
Why is it so important for you to lose weight and live a healthier lifestyle? Make a long list of reasons why you want to be healthier, including vanity reasons, as well as health reasons, and reasons that affect other people in your life (like being there for your kids and grandkids). Read this list and add more reasons to it often. Affirm that the minor sacrifices you are making now are well worth it for all you gain! When you focus regularly on these deep desires, eventually passing up a donut or pizza just doesn’t seem like a big deal. You’ll develop a more balanced perspective that allows you to bypass them easily, or at least indulge a little without overdoing it.
