The idea that drinking water at meals triggers fullness so we don’t eat as much has been around for a long time. It may be wrong. A study at Cornell University found that for every additional three and one-half ounces of water consumed at a meal, participants ate one ounce more food—not less. Switching back and forth between sips of water and food resulted in even more food being consumed. Another study found participants ate a spicy snack about thirty percent more slowly than they did a mild snack. Researchers say heat of the spice slowed people down and that eating slower meant eating less overall. They say the findings might help consumers achieve goals of eating less.
