In reply to the discussion: Modern wheat a "perfect, chronic poison," doctor says [View all]I'm an endurance athlete, a cyclist, who rides more vertical miles every year than most people ride horizontal (last year I cleared 300,000 feet of vertical climbing, or 57 miles straight up.
Fat may be fine for an ultramarathoner who has a very small but steady power output (watts) but I would crash and burn on any one of the 18% grades I climb regularly which involve a semi-sustained power output of 500w or more. Fat doesn't give me that - I can't metabolize it fast enough. For similar reasons, it sucks at recovery. By the time blood vessels are contracting after a workout, your liver is still churning away trying to burn fat going through your system and, finding nothing to do with it, it is stored once again - as fat.
I say this not to brag, but I do know what I'm talking about. There may be individuals who are marvelous at metabolizing fat quickly but they are far closer to the exception than the rule.
