Ratio of carb-protein-fat
All good answers. The recommendation from the ADA is approx. 60-65% carbs (less than 10% simple sugars), 15-20% proteins, 15-20% fats (less than 10% saturated.) I agree with these recommendations. Keep in mind that glucose is the primary energy nutrient for the metabolism of ATP production. There has to be the metabolite of glucose (pyruvate) for fatty acids to enter into the mitochondrial metabolism of ATP. Basically just eat what you know you’re supposed to most of the time. Have a hot fudge sundae once in awhile!
Take care.
