2. Resolve to stop being a sucker.
People can tell you, "Eat everything you want and lose weight!" Come on, really?! Or, they'll tell you about the new fad "kumquat soup diet" or "cabbage and cardboard diet." If you believe all of that, then you are a Double D: dumb and desperate. That is the wrong kind of Double D. You know better. You know the truth when you hear it, right? The truth is, you have to be willing to make some changes and, yes, you have to be willing to make some sacrifices. Unless and until you stop using food for anything other than nutrition and stop believing infomercial hype, you're not going to lose weight and create habits that can help keep it off. Sorry! It doesn't matter if you do The 20/20 Diet or 10 others: if you don't get real with yourself, you simply will not have the results you deserve.

3. Stop chasing diet mirages.
Americans spend $61 billion each year on weight loss products. This is a $61 billion-a-year industry with quite a few "miracle" products that don't work! How is that possible? If you had roller skates that wouldn't skate, surfboards that wouldn't surf, and cars that wouldn't drive, you would not continue to buy those products. You'd be outraged! But diets that don't work? No problem! Millions of people line up to spend billions of dollars because they're desperate for the magic bullet easy fix.

Maybe you're persuaded by one of those celebrities you see showing off his or her new, svelte look while touting diet programs and weight loss production TV commercials. Would you like to take a stab at guessing how much they're paid to lose that weight? The average range is probably between $500,000 and a cool $3 million. I'll bet if someone offered you a couple million bucks to lose weight, you'd pretty much eat sawdust and chain yourself to the treadmill to earn that paycheck.

Until that offer comes your way, stop deluding yourself. Those "miracle" weight loss products and programs you've been using aren't for weight loss; they're gimmicks. You've been obsessing about your weight and impulsively dieting, maybe for years. Obsession is thought, compulsion is behavior, and we have a generation of obsessive-compulsive dieters. Why don't we stop the insanity? Stop chasing diet mirages and finally get yourself on the right path, with the habits you should follow for life to achieve permanent weight loss. Bottom line: if it sounds too good to be true, it is. Yes, there's a lot of noise out there; there's literally a new "diet of the week" every week! But now is the time to quit being a sheep and a sucker.

4. Learn from your failure.

Dr. Phil conducted a national survey of his viewers, social media followers, and others that garnered thousands of responses, and now we've all got the opportunity to learn from each other's histories. 40.3 percent of you lost weight on diets and gained 100% of it back within 90 days to one year. He wanted to know why people fail on diets so much of the time. When you watch those commercials on TV, they don't tell you why you're going to fail; they just tell you how great everything's going to be. But you deserve the truth, so Dr. Phil set out to find it. Find out seven reasons why people failed to lose weight -- and learn how The 20/20 Diet can help you overcome them.

5. Start now.

We all come to critical junctures in life, when we are at a precipice where all things wrong can be made right. Let this be your moment in time. The past is over, the future hasn't happened yet, the only time is right now. This can be your threshold moment of change. The next year of your life is going to go by whether you're doing something about your weight or not. You cannot stator the march of time. Choose denial and you will just get bigger and bigger. Ply yourself with too-good-to-be-true schemes and you will just get bigger and bigger.

Don't let days turn into weeks, weeks turn into months, and months turn into years while you sit around not doing something that you are fully and totally capable of doing. You can do this! I promise you that you can, even if you have doubts. Since the next year of your life is going to go by whether you are doing something about your weight or not, now is the time to get started.
