I'm curious if people can shed some light on this for me....

I know there are many benefits to being efficient at burning fat for fuel, including better blood sugar control, much more 'bang for your buck' in terms of ATP per molecule, healthy weight maintenance, blood profiles, etc.

What other differences are there in the metabolism between fat and carbs?

I would assume that aside from the lactic acid (produced anaerobically), once the glucose or fat is converted into acetyl co-a and enters the TCA cycle and ETC it is the same from there on out (aside from the far greater number of ATP produced).

What made me think about this is reading how the endogenous production of AGEs may be as harmful or more harmful than exongenous AGEs that we ingest from cooking, etc.

So are there benefits of less oxidative damage to athletes for example, who can run 10k on all fat metabolism vs. the same distance burning a lot of carbs?

thanks

Lucas Tafur writes an interesting, and highly technical post on this.

Somewhat amusingly, I now have Lucas Tafur's old domain name, so this was pointing to my website instead of his. Fixed it. – Ambimorph Aug 4 at 8:40

Also may I add, what about acidity levels?

	My first thought about acidity is that anaerobic metabolism of glucose would cause the blood to be more acidic due to the lactic acid that is produced and then buffered. – Jeff Jun 18 2011 at 19:25
	The blog in the response by Ambimorph seems to agree, in a much more technical manner ;) – Jeff Jun 18 2011 at 19:50
