I've been a triathlete for 8 years.  I've completed 3 Ironman races. I have always found it intriguing the number of Ironman athletes I see who have a (relatively) high percentage of body fat. I see competitive athletes with guts. 


I've have definitely noticed that I have a more consistent energy with the higher protein diet and "slow carbs".  More muscle mass helps burn more calories when at rest.

The author, Tim Ferriss, is one of a kind. An interesting read whether you need to lose weight or not.

Anyone else trying The 4-Hour Body diet by Timothy Ferriss?  I have enjoyed good success with it in reducing percentage of body fat. Focus of the diet is a "slow carb" diet combined with weight training. I've lost 8 pounds since 1/1 and lowered my percentage of body fat by 5%.  


Like a lot of triathletes, I was a carb-junkie.  Despite hard training I always had a ring of fat around my waist. Finally, it is starting to disappear.

I've tried the solids. They are kinda chewy and stick to your teeth a little, but I think I can get used to them. I plan on using them more on the run portion of a tri along with water. They will be easier to carry than gels.

Has anyone tried the Hammer Perpetuem solid tabs yet?

Thought this group might have some interest in the newest guidelines for Vitamin D..which seems to be a hot topic lately. Written by Ironman Triathlete

Great point, Robert - definitely make sure that your RD has experience w/ endurance sports. Look for people who have the letters "RD, CSSD" after their name - they have a special certification for sports nutrition. But even still, it's good to find someone who is an RD, a CSSD, AND has experience w/ endurance sports specifically. Good luck w/ your appointment, Joe!

Make certain your RD clearly understands and has LOTS of experience with 70.3 and Ironman distance training and racing. I would go so far as to say that make sure they too are a triathlete that races this distance. I have found that many RD's take their knowledge and extrapolate to endurance athletes where it does not fit. Their education is in foods for the general population, not in fueling an Ironman athlete. Though Tricia had success with her RD, many have not and its usually because the RD's lack of experience with the discipline of triathlon and the complications that arise from exercising this distance in the heat.

Joe, I would suggest that you make an appointment with a Registered Dietitian who specializes in nutrition for endurance sports. It's really worth it, if you want to optimize your performance - I did it last year before I started training for IM AZ, and I had the best race of my life. You can find one in your area by going to the following website: http://www.scandpg.org/mapsearch.php Good luck in AZ, it's an awesome race!
