if one single thing helped me lose 100 pounds I would have to say it was my recumbent bike. I recommend speding the money and getting one. It takes the pressure off your back--which is essential when you start out heavy and out of shape. I started doing it for 3 minutes a day! It was all i could do! I was thrilled when i worked up to 5 minutes! And i used music to time myself--I did not pay attention the dials and meters....I would pedal thru one song. Then two songs. Then I would pedal thru one LONG song....or one whole commercial break.....and every time I was hungry or bored or depressed--I got on the bike and FORCED myself to pedal for one song...or two songs...get the idea? I replaced my addiction and escapism with something healthier...it got to the point that I CRAVED my time on the bike..endorphins and all that good stuff. The pounds dropped away. It took 18 months, but I lost 100 pounds and I kept it off for 7 yrs now. I still use the bike, but I am not now doing the 15 miles a day that it worked into by the end of the diet...and I am strong and healthy.
