1. What exactly is a low carb diet to you folks? Is it 50g, 100g or 160g per day? No-one seems to agree on this and let’s face it you’re pretty smart people so this should be easy to agree on. Can’t you all just pick a number out of a hat or something? It’s all a bit confusing.

2. Are you in a hurry? Dietary interventions for health trials typically last a minimum of 4 weeks and up to 12 months in some cases. Why do some very smart folks think that a 5 or 7 or 14 day fat adaptation period is sufficient for an objective analysis of the fat fueling hypothesis?

3. “The fight is won or lost far away from witnesses – behind the lines, in the gym, and out there on the road, long before I dance under those lights.”         When you study “performance” at a single point in time is that not a bit like studying a room through a keyhole? Do you like to dance yourself?

4. Does recovery or career longevity not interest you very much because you’re in a hurry and it’s not as sexy as performance? I ask because fat adaptation seems to lower markers of inflammation which must be helpful for those things, right?

5. If an athlete habitually eats say 75g/carbs and 70% fat daily but then 1-200g/carbs on the day of a competition, would you say that athlete is not LCHF at all and is in fact a carb cheat? Should carb cheats be banned?

6. The current world high jump record is 2.45 by Javier Sotomayor. It’s been around way too long. Mutaz Essa Barshim jumped 2.43 this year. Now, I know he’s lean as hell but if he could drop even 0.5kg on a well formulated LCHF diet and retain his power don’t you think that might help him get there or would the ketones kill him first?

7. On a scale of 1 to 10, how scared are you of ketones?

  1. The answer to question 1 is ‘it depends’. For an endurance athlete’s rest day it might be 50g and for heavy training / competition it might be 150g. Timing and targeting; check out the work of your fellow countryman Barry Murray. Question 5, why do you object to the well-established principle of race high train low? Question 6, can you cite a single example of retaining high-end power whilst LCHF? (also, an even-lower body fat may compromise an ultra-lean athlete’s health, in particular the immune system) Great questions apart from those!

    • Thanks for dropping in Andy! Re Q.1 – the scientists do not seem to have agreed this amongst themselves so my point here is how can they begin to even contemplate objective trials? I have seen trials were low carb is anything up to 150g/day for example! Q 5 – I do not, but the scientists seem to be stuck on the point that if an athlete competes at 150g on comp day then he is not LCHF. Well, if the habitual diet is say 50-75g/day and 60-70% fat 6 days/week, why is he/she not low carb when in fact their weekly average daily intake might be <75g/day ? They tend to look at single point in time references only. I know Barry and love his work – this will be a brilliant workshop if you are in the area. highly recommended. Cheers for a great contribution. championseverywhere.com/running-workshop-optimised-runner-barry-murray-ce …
