Macronutrient (im)balance drives energy intake in an obesogenic food environment: An ecological analysis.

ABSTRACT:

Objective

The protein leverage hypothesis (PLH) postulates that strong regulation of protein intake drives energy overconsumption and obesity when human diets are diluted by fat and carbohydrates. The two predictions of the PLH are that humans (i) regulate intake to maintain protein within a narrow range and that (ii) energy intake is an inverse function of percentage energy from protein because absolute protein intake is maintained within narrow limits.

Methods

Multidimensional nutritional geometry was used to test the predictions of the PLH using dietary data from the Australian National Nutrition and Physical Activity Survey.

Results

Both predictions of the PLH were confirmed in a population setting: the mean protein intake was 18.4%, and energy intake decreased wi
