Count Bites, Not Calories To Reduce Weight


Washington D.C,: The key to a slimmer waistline might lie in counting bites, not calories, according to a recent study.

New wearable technology is helping to provide novel weight loss tools. One way is by providing bite count feedback, which allows users to keep track of the number of bites during a meal. Researchers at Clemson University wanted to analyze how providing bite count feedback might influence eaters in different situations and determine its efficacy in the presence of environmental cues linked to overeating.

The study found that people who received bite count feedback ate less and reduced their overall intake during a meal.

Investigators recruited young adults to consume a meal in the laboratory. In the first round, some subjects were outfitted with bite count feedback devices and given either a small or large plate. The group that received bite count feedback significantly reduced their intake regardless of plate size, although, those given larger plates still consumed more than those given smaller plates. Larger plate sizes have been positively linked to overconsumption. While providing bite count feedback helped mitigate the known influence of plate size, it was not enough to overcome it completely.

“It was found that the presence of bite count feedback led to a reduction in overall consumption. This finding is consistent with current literature that shows feedback on consumption leads people to consume less,” explained Phillip W. Jasper.

He added, “It was found that this type of feedback does not eliminate the effect of environment cues such as plate size. Individuals may eat less when they receive bite count feedback, but feedback alone may not be sufficient in terms of helping them to take an ‘appropriate’ or ‘normal’ number of bites, particularly in the presence of large plates.”

In the second round, subjects were given either a low-bite goal (12 bites) or a high-bite goal (22 bites) for their meal. Interestingly, both groups met their goals, but the low-bite group took bigger bites, which resulted in both groups having comparable levels of consumption. This revealed a complex relationship between bite count goals and energy intake.

“It is possible that this compensatory behavior is intentional, a reaction to a perceived limitation such that participants believed 12 bites to be too restricting of a goal,” noted Mr. Jasper. “In other words, in an effort to reach satiety while not surpassing the given goal, participants felt as though they needed to take larger bites than they typically would.”
