I have stated it before and I will state it again.
Carbohydrate requirements should be largely dictated by training volume, frequency & type (total energy demand) constant tracking should be in place, and then tweaked according to goals and individual response.
Carbohydrate requirements should not be dictated, as a result of filling out a metabolic typing questionnaire. The example I have used before, what if an endurance athlete turns out to be a “protein” type (using the metabolic typing method), however this individual trains 2 times per day and clocks over 100 miles of running per week.
Does that mean you are going to base your carbohydrate requirements on some silly questionnaire, with no evidence supporting its usage or base your calculations on total energy demand, and then adapt accordingly from there, based on response?
I’d hope you would choose the latter…
Beat the BS, metabolic typing is based on zero evidence!!!
