Many of us trying to lose weight look for a dietary option that best suits our current tastes and desires.

And we are willing to look under every stone to find it.

But let’s set that aside for the moment and look objectively at this study that compared high-protein/low-fat diets with high-carb/low-fat diets.

Bread- and donut-lovers, you’ve been warned!

Researchers from Arizona State University1 recruited ten healthy, normal weight female volunteers between the ages of 19-22 to eat one of the two diets and have their levels of postprandial thermogenesis measured.

Postprandial is fancy talk for “after meal”.

Thermogenesis is fancy talk for “heat-producing”, which relates to the body burning calories.

e.g., important for weight loss.

In any case, though the sample size was small, the researchers did manage to randomize the subjects into the two diet camps and measure the levels of postprandial thermogenesis.

After-meal heat production.

The results were quite significant. The high-protein/low-fat group averaged about double the level of postprandial thermogenesis than their high-carb counterparts.

Combined with other studies that have shown high-protein foods to be more satiating2, this could lend good credence to the concept that high-protein diets are beneficial for weight loss.

Of course, this was a small study, so larger ones would be helpful to replicate the findings, determine ideal macronutrient ratios, etc., but at the very least this gives us some insight into how the body might respond to different diet types as they relate to weight loss.
