(see my post on the re-engineered plan I used for 2014 Ironman Florida)
When I started eating low carb high fat (LCHF), I was avoiding sugars and grains as if my life depended on it. I trained and raced all of 2013 trying not to use sugars. Prior to switching to LCHF, I was using the typical sugary stuff that was not much different from what most people use. For me, the sugary stuff was always too sweet on long training days except when I used a custom formula from Infinit Nutrition. With the custom formula, you can dial up calories, add/reduce this or that, but the best part was you can set the flavor down to near nothing!
So, what the heck was I supposed to do for nutrition if I could not use sugars and trying to avoid products with wheat and dairy?
