Help people diet and lose weight in a healthy way

Getting fit and having a nice healthy weight is the goal of many people.  I personally have strived for this since I was 17 years old.  Over the years, off and on I have read magazines, exercised, tried different diets and taken a wide variety of supplements.  For me learning about my own body has really paid off.  It seems like I have taken different exercise programs, diets and supplement suggestions to try to create my own program.  I feel everyone has a different body type, needs and desires.  Understanding ones own body, I think may be the most important variable in creating the body that one strives for.  I am pushing 50 now and have seen products, programs and ideas come into vogue, morph and be shown to be worthless.  In the 80′s protein tasted like chalk.  I had a college nutrition class that basically said any extra protein was a waste.  Later, it was said, perhaps protein does work.  Coffee has went back and forth as demon to a cancer fighter.   I am sure as new science continues to unfold, pros and cons will come to to the forefront of various supplements, diets and exercise programs as new methods and plans are developed.  The goal here is to find, discuss and evaluate through personal experience what new products, programs and ideas work or don’t work. Quite honestly, trying to live a clean, healthy life has greatly affected my happiness.  Although, I must admit many times throughout my life I have let myself go and fallen out of shape.  But, I have always fought to try to come back to what I consider the healthy side of life and always been happy when I have.  Whenever, I have started my way back to being healthy I always start back slow with baby steps and have slowly formed the habit again.  You can’t run a marathon if you can’t run 1 mile.  As long as you are on the path, it feels good to just get started and start to form the habit.  I have so many friends that started soooo hard core and then hated the experience and quit.  To me the most important thing has always been, just start on the path ever so slowly, but form the habit, then slowly build from there.   Anyway, please post any experience, personal knowledge, ideas or questions you might have.
