Food Quotient

Earlier I looked at how the Respiratory Quotient relates to future fat gain (RQ and Family Factors). This paper reviews evidence that the macro-nutrient composition of the diet and the maintenance of energy balance are correlated.  (Am J Clin Nutr. 1993 May;57(5 Suppl):759S-764S. Food quotient, respiratory quotient, and energy balance. Westerterp KR.).

Given the timeframe of the paper it reaches some predictable conclusions in support of a low fat diet but the text itself indicates otherwise. One interesting comment, though relates to the dietary figure of merit – Food Quotient:

…in the long term, the respiratory quotient (RQ) is closer to the food quotient (FQ) for subjects eating high-fat diets than it is for subjects eating high-carbohydrate diets.

What is the Food Quotient (FQ)? From  (Søren Toubro, Thorkild I. A. Sørensen, Charlotte Hindsberger, Niels, Juel Christensen, Arne Astrup. Twenty-Four-Hour Respiratory Quotient: The Role of Diet and Familial Resemblance. The Journal of Clinical Endocrinology & Metabolism, Volume 83, Issue 8, 1 August 1998, Pages 2758–2764).

The largest factor is carbs.  The FQ for my last week’s meals was:

FQ g cals portion cals Numer. Denom.
Carbs 22.8 91.2 0.039 0.0081 0.0081
Fat 191 1528 0.654 0.1040 0.1479
Protein 179 716 0.307 0.0592 0.0745
Total 2335.2 0.1713 0.2305
FQ 0.743

This is spooky close to the value I got at the start of my VO2 max test (0.73).
