Some of you have mentioned getting headaches....for many of you, it is the change in your caffeine intake.  Kudos to you for doing that, but feel free to wean yourself off the black bean instead of going cold turkey! 

Also, quick story: at a cert Glassman (who helped Sears with some of his initial studies).  The folks involved with the west coast study (some CFers) did not decrease their coffee intake.  The folks in the east coast study did.  They found no difference in weight loss or performance.  While Sears does suggest lowering caffeine intake to decrease inflammation, it is not a requirement to stay in the Zone from what I understand.  You guys feel free to fill me in on anything you have learned!

Also, check out www.Robbwolf.com.  He is the guy that will be doing the nutrition seminars for CF in the near future.  He addresses the increase in fat for those of you who have your body/performance pretty close to optimal and are starving.  You need to up your fat blocks.  See what he says about it here!  PS: Rob is pretty hard core in his take on nutrition.  If you float around his blog, don't be scared!  He is pretty into the paleo diet...which is great, but not as realistic for most of us!
