Caloric Restriction vs Bodybuilding

[Guest guest]

From what I've seen, although natural bodybuilders are interested in

health and do restrict calories when trying to 'get cut' for whatever

reason, the goal is to maximize metabolism and body temperature. Some

even attempt to burn calories just for heat, not for work.

Obviously this is not what I want to do, but do I need to reduce my

muscle mass to gain the benefits of CR?

I'm 5'8 " and weight 185 with 12% bodyfat. My goal is to get to 170

pounds which would put me at around 6% bodyfat. My fat percent seems

in line with Dr Walford's suggestions, but would that be too much

muscle to gain the life extension benefits?

Thanks for any help,
