Hi b-rider
This is my story.
Five years ago I weighed 285 pounds, I changed my diet a high carb/high fiber diet, I use no salad dressing, salt or butter. eat very little red meat and as few sweets as possible. I cycle as much as possible, commute to work, run errands and just ride for enjoyment. three years ago I hit 175 pounds and have been at this weight since. My advice to you is, don't diet, change your life long eating style. excercise regularly and give it time. Remember, it took a lot of time and food consumption to get to 285, it's not going to go away over night.

Good luck, keep with it.
