Thinking Before Eating Provides Time To Justify Giving In To Temptation: Study

While "thinking before eating" might seem like a good weight loss strategy, a new study suggests it could actually backfire because humans are really good at rationalizing things.

Researchers from Utrecht University found that taking the time to think before eating actually gives us time to rationalize why we should be able to eat that thing we're trying to avoid.

"They can justify having the cake on account that it has been a hard day, or that they will exercise tomorrow, that it is a special occasion, or that it is impolite to refuse," study researcher Jessie De Witt Huberts said in a statement. "This is when justification processes become a slippery slope ^[1] -- as the reasons are often applied ad hoc, they no longer form strict rules that regulate when you stick to your diet and when you can cut yourself some slack."

The findings are based on a review of 50 published studies; the new review is published in the journal Personality and Social Psychology Review ^[2] .

"With justification we refer to making excuses for one's discrepant behavior, so that when experiencing a self-regulation dilemma between immediate impulses and long-term intentions, people resolve the conflict by developing and employing justifications that allow violations of the goal they endorse," the researchers explained in the study. "Accordingly, rather than inhibiting motivations from the impulsive system, the reflective system can also facilitate them, leading to self-regulation failure."

Use A Bigger Fork

A study published in the Journal of Consumer Research shows that restaurant-goers who <a href="http://www.jcr-admin.org/files/pressPDFs/071311193612_mishra.pdf" target="_hplink">eat with really big forks</a> (20 percent bigger than a normal fork you'd find at a restaurant) eat less food and leave more on their plates than people who eat with really small forks.

A possible explanation for this finding is that when people use small forks to eat, they feel like they are not making any big <a href="http://healthland.time.com/2011/07/15/using-a-big-fork-may-help-you-eat-less/?xid=huffpo-direct" target="_hplink">progress in eating their meal</a> and quelling their hunger pangs, TIME reported. In addition, the restaurant-goers who ate with the smaller forks and were given bigger portions of food at much more food than if they just had the smaller forks or if they just had the bigger portions.

Eat From A Smaller Bowl

Research from the Georgia Institute of Technology shows that people eat 31 percent more ice cream when they eat out of a 34-ounce bowl, rather than 17-ounce one, ScienceDaily reported. Researchers explained that's because people eat about 92 percent of what they serve themselves -- so if you <a href="http://www.sciencedaily.com/releases/2006/08/060803082602.htm" target="_hplink">serve yourself more, you'll eat more</a>.

Get Some Sleep

Columbia University researchers found that <a href="http://www.thirdage.com/news/sleep-deprivation-may-increase-hunger_3-26-2011" target="_hplink">sleep deprivation can also lead to more calories consumed</a>. They found that women who only got 4 hours sleep the night before ate 329 more calories in a nine-hour period compared with if they weren't sleep deprived, while men ate 263 more calories when <a href="http://www.huffingtonpost.com/dr-michael-j-breus/sleep-more-lose-weight_b_857080.html" target="_hplink">sleep-deprived</a>.

"It has an impact on cognitive restraint," study researcher Marie-Pierre St. Onge told ThirdAge. "High-fat food is tempting, and maybe on <a href="http://www.thirdage.com/news/sleep-deprivation-may-increase-hunger_3-26-2011" target="_hplink">short sleep you can't restrain yourself</a> as well, while on full sleep you can resist more easily."

Mind Your Environment

<a href="http://www.huffingtonpost.com/2011/09/02/mindless-eating-environment-location_n_945712.html" target="_hplink">WHERE you eat your food</a> could also factor in to how much you eat and whether you're eating food even though you're not hungry, according to research from the University of Southern California.

Researchers had movie-goers say whether they were regular popcorn-eaters or not, and then they had them eat either stale popcorn or freshly popped popcorn. The regular popcorn-eaters ate just as much stale popcorn as fresh popcorn, while people who didn't consider themselves regular popcorn-eaters ate significantly less stale popcorn than fresh since it didn't taste as good.

"The results show just how <a href="http://www.huffingtonpost.com/2011/09/02/mindless-eating-environment-location_n_945712.html" target="_hplink">powerful our environment can be</a> in triggering unhealthy behavior," study researcher David Neal said in a statement. "Sometimes willpower and good intentions are not enough, and we need to trick our brains by controlling the environment instead."

Hide The Junk Food

Research from Cornell University shows that we are three times more likely to <a href="http://www.huffingtonpost.com/2011/09/29/see-first-eat-visible-food_n_984004.html" target="_hplink">eat the first thing that we see</a>, compared with the fifth thing we see.

In that study, researchers took photographs of 100 kitchen cupboards and asked the owners to keep records of what they ate. Researchers also tried moving the food around in the cupboards to see if that impacted their food choices -- and found that it did.

The research shows that "we end up being masters of our own demise, to some extent," study researcher Professor Brian Wansink, Ph.D., author of "Mindless Eating: Why We Eat More Than We Think," told HuffPost.

Eat Using Your Non-Dominant Hand

Research published in the Personality and Social Psychology Bulletin shows that <a href="http://thechart.blogs.cnn.com/2011/09/20/overeating-which-hand-are-you-using/" target="_hplink">eating with your non-dominant hand</a> can help you to decrease the amount of food you consume, CNN reported.

The finding was part of the same movie-theater/popcorn study, where it was discovered that environment plays a part in mindless eating. Like in that experiment, researchers gave study participants either fresh or stale popcorn. They found that people who used their non-dominant hands and ate the stale popcorn ate 30 percent less than if they used their dominant hands, CNN reported.
