Overfeeding Protein – Carnivore Diet

I’ve been doing the carnivore diet for the past 9 days. My weight dropped a couple of pounds and has stayed low in spite of eating a large excess of calories.

I am eating almost twice my protein macro and my blood sugars have been doing fine.

High Protein Stimulates Metabolism and Fat Doesn’t

That raises the question of whether eating too much protein results in a weight gain. Somebody actually studied the effect of overeating protein on 24-hour Energy Expenditure (24EE). (Bray GA, Redman LM, de Jonge L, Covington J, Rood J, Brock C, Mancuso S1, Martin CK, Smith SR. Effect of protein overfeeding on energy expenditure measured in a metabolic chamber. Am J Clin Nutr. 2015 Mar;101(3):496-505.). The objective was to quantify the effects of excess energy from fat or protein on energy expenditure of men and women living in a metabolic chamber.

The study reached the conclusion:

Excess energy, as fat, does not acutely increase 24EE, which rises slowly as body weight increases. Excess energy as protein acutely stimulates 24EE and SleepEE. The strongest relation with change in 24EE was the change in energy expenditure in tissue other than muscle or fat-free mass.

Interesting…

2018-05-31: Interesting article on overfeeding in general. Lot of good studies listed at the end. Not a Low Carb study but it points out that Protein overeating is not all that well studied.
