bias ,â we tend to finish a serving if it seems like a natural portion of âone,â and we tend to take one serving, no matter what the size. In a study where people could help themselves to big pretzels, people took one; when people were instead offered big pretzels cut in half, they took one half-pretzel. Also, eating directly from the container makes it impossible to monitor how much weâre eating. Whether the product is candy or shampoo or cat food, the bigger the package , the more people use. (In what seems like an aspect of the same principle, Iâve noticed that I finish books faster when I have a bigger stack from the library.)
Taking bites while cooking, eating off plates, sharing food, or eating food served in multiple bite-sized servingsâdim sum, tapas, hors dâoeuvres, petits fours, appetizers ordered for the tableâalso make it hard to track consumption accurately (which is likely part of their appeal). One way to monitor is to save the evidence left behindâthe pile of bones, the peanut shells, the candy wrappers, the dayâs coffee cups or soda cans or beer bottles.
Context matters, too. One study of package design showed that people avoid the smallest and largest beverage sizes; therefore, if the smallest drink size is dropped, or a larger drink size is added (such as the Starbucks Trenta), people adjust their choices upward.
As the weeks wore on, along with keeping a food journal, I added a new monitoring habit: No seconds . When people preplate their food and eat just one helping, they eat about 14 percent less than when they take smaller servings and return for more helpings. Iâd often pulled this trick myself: Iâd give myself a small serving, then go back for more. The need to monitor exactly what Iâd eaten, in order to record it, forced me to stop this little game.
As part of the Strategy of Monitoring, I decided to buy a digital scale to weigh myself. Although some experts advise people to weigh themselves just once a week to avoid becoming discouraged by natural fluctuations, current research suggests that weighing each day âwhich may strike some people as excessiveâis associated with losing weight and keeping it off. Until now, Iâd only weighed myself when I went to my cardio gym, but now I wanted to get serious about monitoring. (Side note: people weigh their highest on Sunday ; their lowest, on Friday morning.)
Iâd wanted to buy a scale for more than a year, but I put it off because of Eliza. Eliza is very easygoing, and although she spends a lot of time choosing her outfits, changing the color of her nail polish, and trying to grow her long brown hair still longer, she isnât preoccupied with her weight or any particular body part. Nevertheless, plunking down a scale in the bathroom that she shares with Jamie and me seemed like exactly the wrong message to send to a thirteen-year-old girl.
One of my Personal Commandments is to âIdentify the problem.â What was the problem? âI want a digital scale, but I donât want Eliza to see it.â Solution: I bought the scale and put it in a little-used closet where sheâd probably never find it.
People find other ways to monitor their bodies. A friend has a pair of jeans that she never wears except to pull them on to see whether theyâre tighter or looser than before. For myself, Iâm much happier relying on my digital scale than on form-fitting clothes. Most days, I wear yoga pants and a hoodieâthe point of which is that theyâre delightfully stretchy and nonconfining.
When I first started to use the UP band, I ignored its mood-monitoring and sleep-monitoring functions. Perhaps surprisingly for someone whoâs preoccupied with happiness, I had no interest in tracking my moods. As for sleepâI was a sleep zealot , so I didnât think I needed to monitor it. Sleep, as I remind anyone who gives me the opportunity, is crucial
