A sample size of only 19 - however - it looks like to me that they were thorough, having the participants stay at the NIH -
For part of these visits, they lived inside a special room called a metabolic chamber, which captured all the air they inhaled and exhaled as well as their urine. This careful collection of body gasses and fluids allows researchers to precisely measure how many calories people are burning and what those calories come from—carbohydrates, fat, or protein.
People lost more total fat on the low-fat diet than they did when they were eating the low-carb diet. And cutting fat didn’t appear to slow metabolism, while cutting carbs did.
