Liquid versus solid carbohydrate: effects on food intake and body weight
DiMeglio and Mattes gave fifteen people the same amount of extra carbohydrate every day for four weeks, once as a fizzy drink and once as jelly beans, with a four-week gap between. Everything else about their eating was left to them. When the extra energy arrived as a solid, people compensated almost exactly, eating less of everything else so that total intake barely moved. When it arrived as a liquid, they did not compensate at all; total daily energy went up by the full amount added, and body weight and body mass index rose over the four weeks. Physical activity and reported hunger did not change in either condition, which rules out the simplest alternative explanations. The study is small and short, and it is the cleanest demonstration of the claim that liquid calories evade the mechanisms that regulate intake. This vault cites it whenever drinks are treated as equivalent to food.
