There are many avenues to weight loss and only you will know what is best for your body in order to loose weight. I have yet to find anything though that works without some hard work. That, I think is where your satisfaction will come from. Knowing that you worked hard to become healthy can be great motivation to stay that way.
If you have had success in losing weight, I would love to hear how you did it. Perhaps it can help motivate us all to work hard for our health.
