Speed Eating And Fat Loss: Diet Advice Your Mom Was Right About All Along
New research proves that the weight loss advice your mom gave you is true after all.
A new study just published in a recent issue of the journal Obesity has revealed that thin people eat very differently than heavy people at all-you-can-eat buffet restaurants.
Researcher Brian Wansink and his team from the Cornell University Food and Brand Laboratory observed diners at 11 different Chinese buffet restaurants across the United States.
Their goal was to find out whether the eating behaviors of people at all-you-can-eat buffets varied based on their body mass.
Trained observers recorded the height, weight, gender, age, and behavior of 213 patrons. The various seating, serving and eating behaviors were then compared across BMI levels.
The heavier (higher BMI) patrons:
* ate more quickly * chewed more per bite of food * used forks * sat facing the food buffet
The thin (lower BMI) patrons:
* ate more slowly * chewed less food per bite * used chopsticks * sat facing away from the food buffet
This study confirms earlier research from the University of Rhode Island published in the journal of the American Dietetic Association which found that eating slowly leads to decreases in energy intake.
Scientists even have a name for this now:
Time Energy Displacement means that the more time you take to eat, the less energy (calories) you are likely to consume. The faster you eat, the more energy (calories) you're likely to consume.
But wait, there's even more! A study from the University of Alabama looked at satiety (how full a food makes you feel), energy density (calories per unit of volume) and eating time of various foods. To maximize the effects of Time-Energy Displacement, it was found even more advantageous to choose foods that FORCE you to ingest calories more slowly.
This includes choosing more:
* Foods that have a high satiety factor such as high fiber and high water foods (so you feel fuller more quickly) * Foods with a high "chew factor" (so you can't eat them fast if you tried; you have to chew them thoroughly) * Foods with a low energy density such as high fiber vegetables and lean protein (so you'd get tired of eating before you took in a lot of calories).
These results also confirm all the studies that have been advising us not to drink our calories. Liquid calories, especially soft drinks and desert coffees are two of the biggest sources of excess calories in the typical American's diet.
The problem: calories in liquid form can have a very high caloric density and can be consumed very quickly. Liquid calories also do not activate the satiety mechanism in your brain and gastrointestinal tract the way solid food does.
"Don't inhale your food" used to be an admonishment about proper eating etiquette you heard from your mom. It is now scientifically-proven fat loss advice.
