Best way to lose weight - I lost 73 pounds

I lost 73 pounds in about 6 months.  In the first 2 months I lost 27 pounds.   Growing up and into my 30s I was skinny in fact when I was 39 years old I was still around 150-160 pounds.  Over the next few years I ballooned up to a whopping 240 pounds.   I am 5' 10"... So how did I do it?  The answer may surprise you....so if you have any questions please fill free to blog me here and I will chat with ya about it.   It now has been 2 years and I am about 180 pounds and feel great!   I am 53 years old and my health is a concern to me.
