It seems that everyone has advice for people who want to eat less. A new study supports at least one piece of common wisdom—taking smaller bites and leaving food in the mouth longer reduced the total amount of food eaten.
Savoring small bites
The study, published in the American Journal of Clinical Nutrition, included 22 healthy normal-weight adults who each participated in seven separate eating tests.
The participants ate approximately 3 to 4 ounces less chocolate custard when the bite sizes were small than when they were large, and approximately 1.5 to 2.25 ounces less when they held the custard in their mouth longer than when they swallowed it quickly. Even during the free-bite-size tests, those who took bigger bites ate more custard.
Quality affects quantity
A number of previous studies have observed that food texture and speed of consumption can influence our experience of fullness and satisfaction. For example, liquid foods and semi-solid foods, which tend to be consumed in larger mouthfuls and more quickly than solid foods, have less effect on reducing appetite than solid foods of equal calories that require chewing time. The end result is that we can consume more calories from these foods without feeling full or satisfied.
The new study adds to the evidence that, in addition to texture, bite size and the time that food is in the mouth are important factors in determining how much we eat. The study’s authors note that “the results of our study show that greater oral sensory exposure to a product, by eating with small bite sizes rather than with large bite sizes and increasing oral processing time, significantly decreases food intake.”
Slow it down
For many people, generally consuming fewer calories each day would be a healthy change. Following the practice of taking small bites, holding them in the mouth whether or not they need much chewing, and waiting between bites may help to trigger the sensation of fullness before you’ve overeaten. Here are some other ways to keep your appetite and eating under control:
