From: moodypete on 14 Jun 2007 19:01 Hi, I just completed a long distance bikeride (9 hrs/~200km) in which I guess I probably burned about 3500 calories which theoretically is about a pound. Anyway, I was wondering. Where does all the weight go? Loss of carbon through production of CO2? The tradional #1/#2? Heat (e=mc2???) Anyway, just wondering. BTW, my bike trip wasn't planned...I just ended doing a Forrest Gump thing and kept riding from town to town :) (It was fun, but the taxi fare home was a killer :) )

That's like burning a steak to a charred puck and then asking where all the meat went. Stored fat, protein and carbohydrates are broken down via chemical processes (metabolic pathways) into forms your muscles can use to do work. The main byproducts of the processes are heat, carbon dioxide, and water. Even the lactic acid byproduct that causes the burning sensation in muscles when you work too hard and too fast is run back through the process to produce more energy. You really do "burn" fat, it's just done with chemically instead of with fire. -- Denise denise dot howard at comcast dot net ACE and AFAA certified fitness instructor AFAA step and kickboxing certified
