1.) Focus on a change of heart, not a change of mind. Losing weight through changing what and how much you eat doesn't happen because you rationally decide to lose weight. You have to have a change of heart; that is, you must get in touch with your deepest, heartfelt desires.
Your motivation may not be positive. Indeed, it may stem from a fear of loss. For example, you may not want to get sick. Or you may not want to be ostracized. To get in touch with your motivation, think about the negative consequences of not changing as well as the positive ones. Getting fit must become a priority and your life must be organized accordingly. Nobody can change you but you, and once you've made the changes, you need to stay focused. Successful individuals keep their motivation in the forefront of their minds all the time.
2.) Practice self-discipline. Self-control is a muscle that, like other muscles, needs exercise and strengthening. Change doesn't happen because you want it to happen. Each time you resist temptation, you are developing greater self-control. Success breeds success. Facing down temptations builds strength for future decision moments. Some of my clients throw away their favorite food as a symbolic act that shows they have control over the food and not the other way round.
Self-discipline is required for behavior change, but does that mean that the lack of self-discipline causes obesity? No. That would be like saying aspirin helps a headache go away, so headaches are caused by a lack of aspirin -- which is nonsense!
3.) Eliminate or reduce sugary, fat-laden foods. Such foods create physical changes at a cellular level that alter how our brains and bodies react. When analyzing your level of addiction, consider both physical dependence (changes at the cellular level) and psychological dependence (the habitual repetition of a behavior in an attempt to satisfy an emotional need). For example, how often do you use a sugary treat to lift your spirits?
What is often misunderstood is that these dependences exist on a continuum. You can be mildly, moderately or severely dependent, and the degree of dependence determines how difficult it will be to change.
4.) Make history your teacher, not your jailer. You can learn from your mistakes. Instead of [beating yourself up] when you fail to keep your promises to yourself, seek to gain self-knowledge so you won't repeat the error. No one is perfect. Be sure to acknowledge what you are doing right, not just what isn't working.
5.) Surround yourself with friends, family and colleagues who will support your effort. Getting fit and losing weight absolutely require others. Although you alone can make the changes you need to make, you can't make the changes alone. Not only in terms of eating, but in all areas of our lives, we are much more influenced by other people than we imagine. One of the most potent forces for positive change is the emotional support of the individuals who surround you.
You must, however, ask for the support you need. Don't assume that others know what would be most helpful to you. Similarly, you need to avoid those people who aren't on the same page as you. Social pressure can work for you or against you. Hang out with the right people.
