Food Quotient by Diet

The food quotient (FQ) measures the dietary composition. Here’s the FQ of my own diet for the past week:

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

Here’s various diets.

Here’s the FQ for the diets.

Diet FQ
Ketogenic 0.736
Mine 0.743
Vegan 0.764
Atkins 0.753
Paleo 0.816
Mediter 0.825
Zone 0.843
SAD 0.859
Ornish 0.936

Zone Diet Numbers

This shows why some consider the Zone diet to be a balanced diet. Given that a ratio of .85 indicates an even mix of fat and carbs (0.7 is pure fat and 1.0 is pure carbs). This actually provides support that the Zone diet is a “balanced” diet in terms of fuel substrate selection.

My diet is very close to the Ketogenic Diet but with some more protein in it.

PSMF Numbers

It’s surprising that at first blush PSMF numbers are higher than keto numbers given that PSMF burns fat. But this is accounted for in relatively high carbs compared to the keto diet since PSMF is a very low calorie diet.

FQ g cals portion cals Numer. Denom.
Carbs 20 80 0.034 0.0071 0.0071
Fat 20 160 0.069 0.0109 0.0155
Protein 120 480 0.206 0.0397 0.0499
Total 720 0.0577 0.0725
FQ 0.795

A low FQ is not a guarantee that you are burning a lot of body fat. You might be eating a lot of fat, too.

The reason other diets work is that the lower the calories the higher the percentage of the diet that is from fat. And that’s true no matter what the dietary macro breakdown is. That is because the fat comes from the body in reduced calorie diets.
