I hear a lot of stories in the media about people who make some kind of mistake that brings harm to themselves, whether physically, or financially. These people inevitably try to blame their own mistakes on someone else. There's the infamous story of the old lady who spilled coffee on herself, but then sued McDonalds because the coffee she bought there burned her. Of course the coffee burned her! It was hot! It's supposed to be hot! McDonalds gave her exactly what she paid for - a hot cup of coffee. This old lady clearly made the mistake of knocking over the cup coffee. It was her mistake, not McDonalds, but rather than take responsibility for her actions, she blamed someone else.
This is a common problem amoung people who are overweight as well. Many people who are overweight get so frustrated with their efforts to get in shape that they start blaming others for their own failures. "I have bad genetics. I'll always be fat." (Blaming your parents) "I'm too old to get in shape now." (Blaming your age) "I can't exercise because I am handicapped" (Blaming your handicap) "The diet I'm on now works fine." (Blaming your current diet). Let's refute all of these excuses.
"I have bad genetics." Nope. You have the same genetics as everyone else on Earth. All human beings have the same genetic tendencies when it comes to losing or gaining fat. You are no different from the next guy/girl.
"I am too old to get in shape now." Nope. Are you dead? No? Then you are not too old to get in shape. It might take you a bit longer and you would no doubt have to adjust your efforts based upon your medical needs, but it is certainly not impossible.
"I can't excercise because I am handicapped." Nope. This just means you have to adjust your exercise program to compensate for whatever your handicap may be.
"The diet I'm on now works fine." If you are still fat, after all these months/years of being on your current diet, obviously your current diet is NOT working. Try something else. Don't be so stubborn as to think that what has failed you consistently in the past will suddenly, miraculously, start working after all those years of failure. If it doesn't work, put it aside and try something new. The science of nutrition changes every day. What you learned 10,20, or 30 years ago may have long since been proven wrong.
One of the most important things you can do to get in shape, is to admit to yourself that you got yourself into this predicament. Noone else did. Since you are the only one who is responsible for your situation, you are the only one who can fix it. Accept this fact. Yes, it is your fault. Live with it and accept it. You don't need to beat your self up about it and you don't need to admit it to anyone but yourself. Noone else shoved that food down your mouth. You did. You have only yourself to blame and only YOU can fix it. You must make the decision to devote yourself completely to pulling yourself out of the situation you are in. You must then spend as much time as is necessary researching the problem. What am I eating that is wrong? What can I do to improve this? This constant fine tuning of your efforts must be a daily event. How did I do today? What did I do wrong? What did I do right? What can I do tomorrow to correct what went wrong today?
