1) You ignore the importance of context
You ate more because you were hungry? Maybe, but you’re probably not giving nearly enough credit to how context affects you. I’ve posted many times about how context is far more influential than you think.
From Paul Bloom’s How Pleasure Works:
- Protein bars taste worse if they are described as “soy protein”
- Orange juice tastes better if it is bright orange.
- Yogurt and ice cream are more flavorful if described as “full fat” or “high fat.”
- Children think milk and apples taste better if they’re taken out from McDonald’s bags.
- Coke is rated higher when drunk from a cup with a brand logo.
How much you eat is strongly affected by how much those around you eat, but you rarely realize it. Dining with friends? You’ll probably eat twice as much.
At restaurants, people eat more depending on how many people they are dining with. People eating alone eat least. People eating with one other person eat 35 percent more than they do at home. People dining in a party of four eat 75 percent more, and people dining with seven or more eat 96 percent more.
It was all the same $2 cabernet. And we found that if people thought it was from California, they rated the wine as better, they rated the food as better, they stayed at the restaurant about 10 minutes longer, and many of them made reservations to come back.
When we served them the North Dakota wine, it poisoned the entire meal. They didn’t rate the food as good, they left 10 minutes earlier, and they didn’t make reservations to come back.
When you serve dessert, put it on some fancy china, not a napkin:
If they ate it on the napkin, they’d say, “Wow, this is really good.” On a paper plate, they said, “This is really, really good.” If they ate it off of Wedgwood china, they would say, “This is the greatest brownie I’ve eaten in my entire life.” And the amount they were willing to pay for it tripled.
Consumers’ quality and liking judgments concerning identical yoghurt samples differed significantly when tasted either with a metallic plastic spoon or else with a stainless steel spoon, the latter resulting in significantly higher scores.
2) You forget that so much of what makes food good or bad is in your head
Comfort food really does comfort you. Grandmom’s cookies do taste better than other cookies. You can’t tell pate from dog food. Coffee junkie? When you haven’t had your joe anything with caffeine tastes better. Dieting actually makes food look bigger.
Eating organic food might turn you into a jerk. Anything that affirms your feelings about your own morality (“I eat organic, therefore I’m a good person.”) your brain may subconsciously use to justify doing something immoral. (“I’m generally a very good person so it’s okay if every now and then I…”)
Why do people order a cheeseburger, fries, dessert and a *Diet* Coke?
It’s called a “health halo effect.” As long as we have the feeling we’re doing something healthy, we extend it to everything during that meal. Due to this, most people surveyed estimated that a cheeseburger with a salad had fewer calories than the cheeseburger alone.
We feel so good about ordering something healthy, our next indulgence doesn’t feel sinful at all. We also see virtuous choices as negating indulgences— literally, in some cases. Researchers have found that if you pair a cheeseburger with a green salad, diners estimate that the meal has fewer calories than the same cheeseburger served by itself. This makes no sense, unless you believe that putting lettuce on a plate can magically make calories disappear.
(And, no, those fortune cookies aren’t very Chinese.)
3) Food and hunger affect your judgment whether you realize it or not
Hungry judges give harsher sentences. Lemonade can reduce racism. Eating something disgusting can make you feel morally disgusted. Hungry men prefer heavier women and Playboy playmates are thicker during economic recessions.
Kids who skip breakfast misbehave more than kids who eat their Wheaties. After given a snack, all the children are little angels again.
All the children in a class were told to skip breakfast one morning, and then, by random assignment, half of the children were given a good breakfast at school. The others got nothing. During the first part of the morning, the children who got breakfast learned more and misbehaved less (as judged by monitors who didn’t know which children had eaten). Then, after all the students were given a healthy snack in the middle of the morning, the differences disappeared as if by magic.
People who have low blood sugar are far more prone to criminal and violent behavior:
…hypoglycemics were more likely than the average person to have trouble concentrating and controlling their negative emotions when provoked. Overall, they tended to be more anxious and less happy than average. Hypoglycemia was also reported to be unusually prevalent among criminals and other violent persons, and some creative defense attorneys brought the low-blood-sugar research into court.
Across the board, yeah, food puts you in a better mood. To be more exact, research has shown that 2 cheeseburgers = one orgasm. Smiling gives the brain as much pleasure as 2000 bars of chocolate.
They discovered that smiling stimulates our brain’s reward mechanisms in very powerful and surprising ways. How did the power of a smile stack up against other “well-regarded” pleasure-inducing sensations? Depending on whose smile you see, the researchers found that one smile can be as pleasurable and stimulating as up to 2,000 bars of chocolate!
(Health-wise, a little starvation can be good for you, actually.)
So what can you do?
Use this info to help you:
- If you need to concentrate or something is going to require good judgment, make sure to eat something.
- Use your knowledge of the way certain foods make you feel to control and improve your mood.
- Use context to control your eating.
You probably utilize the first two points from time to time but maybe not often enough. The third is very powerful but you probably don’t put it into action.
The good news is that for every external cue that messes people up in our studies, you can solve the problem by doing the opposite. If going from a 10-inch to a 12-inch plate causes you to eat 22 percent more, use a 10-inch or 91/2-inch plate.
Use smaller bowls. Don’t rely on your willpower or the power of education. Don’t say, “Now I know that I’m three times more likely to eat the first thing I see in my cupboard than the fifth thing I see in my cupboard … but I won’t let that influence me.” It absolutely will!
The solution is to make sure that the first thing you see–the thing that’s front and center–is healthier than that chocolate-covered foie gras.
People eat food that’s on the table much more frequently than food that’s off the table, so just put the salad and vegetables on the table. Leave everything else on the counter or stove.
