A Better Way To Pitch Weight Loss

I just finished reading the Shift, by Tory Johnson. It was a very well written book by a woman in the public eye. While I don't feel all of her choices would be right for me, she did make some memorable points.
While walking my dog this afternoon, I focused on one of her thoughts in particular. After one year of focus, she successfully lot 62 pounds and regained her health. Her family were an integral part of her journey, and one of them pointed out that she lost just over one pound a week. She noted that in the past, before her shift, if anyone had pitched her a one pound a week way to lose weight, she would have scoffed at it.
I started to do the math in my head. This week, I will have lost close to 40 pounds in 6 months. When I do the math it works out to be around 1 and a half pounds per week. The manner that I'm approaching weight loss has been pain free, sustainable and above else healthy. I have been eating more whole foods and have been mindful of the sugar and wheat in my diet. I still consume sugar and whole grains, but in much smaller quantities. In fact, my sugar intake is almost negligible.
Over the past half year, I have changed my approach to eating and exercising. The change has been remarkable and something I can maintain until I reach my goal. Maintenance is still a while away, but I will tackle it with patience and by making sensible choices.
So back to the reason for my post....What if everyone started hearing the message that lifestyle change is a long road to take? If people stopped looking for a quick fix to their health issues, would the unhealthy "diets" or pills or injections lose their popularity and fade into extinction?
We live in a world of instant gratification. So many people quit their healthy journey before it even gains momentum. How can we Spark people without preaching?
I'm hoping to do it by walking the talk and sharing my tools with anyone who asks.
Oh yea, and approaching things one day at a time.
