There is nothing you should take more seriously than your health and fitness. Yet so many of us are stuck in unhealthy ruts, desperately wanting to improve but ultimately unsuccessful. Unscrupulous companies capitalize on that desperation and try to get you to believe that if you pay them money, they will make achieving a healthy and happy life easy. Don't fall for their tricks. If the changes you make aren't permanent, then the results won't be either. Fitness isn't a short-term sprint, it's a life-long pursuit. Whatever you do, make sure it's something you can keep doing for most of the rest of your life.
For example, a co-worker of mine has told me about a relative who is trying to sell him meal-replacement shakes. My co-worker is smarter than that - he knows that adopting an overall diet that includes these shakes is not something that he can keep up for the rest of his life. As soon as he drops the shakes, whatever positive benefit they had on him will disappear.

There are numerous others. For any diet or fitness plan you need to ask yourself:
You really don't need to pay money or adopt some kind of exciting new plan in order to achieve better health. It's the simple daily choices that will result in the biggest impact. I know, you really want that quick fix. But there isn't anything quick to the process of losing weight or achieving better health. It's a lifelong pursuit.
