In the simplest of terms: the key to losing "fat" weight is to train at a lower heart rate in base training. Once your heart rate goes over the aerobic threshhold your body requires carbohydrates to fuel you- which makes you crave more carbs rather than teaching your body to use the fat in your body for energy. A no brainer right?

(Not the best graph but you can get the ideal concept from it.)
My last heart rate monitor was a hand me down that wouldn't hold a battery charge. So, I did a ton of research to see what my next purchase should be. Polar was the big winner!
They seem to be at the top of the pack in trying to monitor all three sports of swimming, biking, and running at a comprehensive level while still being user friendly.
I bought the Polar RCX5. So when I'm trying to measure my outputs during a run and I want to know my mph, heart rate, distance, heart rate zones, calories burned etc. I can check it all on my watch. If I want to change the views of data all I have to do is wave the watch by my heart rate transmitter. Easy peasy! Also, they have made it very easy to switch between the different sports- no crazy button pushing there.

I'm still researching a ton on running plans, swimming plans, biking plans, and nutrition. But I'm happy to say my first big buy is marked off the list (Polar). I think I'll be pretty happy with it.
Now to buy a carbon bike. Stay tuned.
