Loss of 0.5 lb from last week. Goal is to lose 2.5 lb to weight 222 on Feb 24th.
My pants are STILL tight!!! Geez! I wore them day in, day out in Austin, Texas for four months and now after losing over 10 lbs, they are still really, really tight around me. I have two pair one blue one Khaki and both are barely fitting me again. The sad truth is it takes 6+ months of steady consistent diet and exercise for me to notice any difference in my appearance, but only a month or two of indulging and slacking off to noticably bloat up.
Since I have been losing weight I have been thinking about where the fat goes... Matter cannot be created or destroyed so it has to be converted into something else, but what? Well wikipedia to the rescue. Just ask the right question: How are fats metabolized?
- Fats are composed of triglyceride and cholesterol and must be broken down with a process called Lipolysis.
- Lipolysis produces glycerol and fatty acids.
- Glycerol undergoes Glycolisis to produce acetyl-CoA and carbon dioxide gas which is exhaled when breathing
- Fatty acids undergo beta oxidation to produce acetyl-CoA
- Acetyl-CoA enters the Krebb-cycle to produce ATP, Hydrogen and more carbon dioxide gas which is exhaled when breathing
- Hydrogen produced in Krebb-cycle is transported to the electron transport chain and is combined with oxygen to produce water and energy for the creation of additional ATP which is the utimate fuel used by cells.
So fat becomes carbon dioxide, water, heat (from metabolic pathway reactions) and ATP (cellular fuel). Oh the cholesterol in fat isn't converted to energy. It is used in your cell membranes, you lose excess cholesterol in your stool.

That was technical...but it is cool to imagine how my body is losing it all. I wonder if fitness wise you have kinda plateaued and that is why your pants are not loosening up? I used to see it (and experience it) all the time. Make sure you are mixing it up!
