How the shape of your glass may affect your shape"},"content":{"rendered":"

Have you ever had one of those nights where you open a bottle of wine (or crack open a carton of chocolate milk) and a couple hours later it is gone. You couldn\u2019t have had that much; you just poured one glass right? Or was it two? It must have been a smaller bottle or your friend helped you finish it quicker. It couldn\u2019t have been the shape of your glassware… or could it?
\n<\/p>\n

\"redIt may be a surprise, but the diameter and height of glassware can distort our perception of how much we pour for ourselves and how much we consume. The recommended serving of wine is 5 fluid ounces. How many of us actually know what that looks like? The typical wine glass holds around 10 ounces, but is usually only filled halfway. If the glass were wider, would you notice? If the glass were longer in the bulb, would you pour more? If the glass were in your hand versus on the table, how would that affect how much you served?<\/p>\n

Brian Wansink PhD<\/a>, who researches changing eating habits and is the director of the Cornell Food and Brand Lab, has studied and found that all of these aspects and characteristics surrounding our dishware and glassware affect our portion sizes. In one study, Wansink found that the width of the glass, the color of the drink, and the position of the glass positively affects how much subjects poured in their glass; pouring more as the width increased.  When the drink was harder to see (clear), or when the drink was on the table versus in their hand they poured more also. This is important because liquid calories are the most deceptive; they go down easily and stick. A single 5-ounce portion of wine is 110 calories \u00b1 10; if that portion was doubled in addition to consuming a standard diet, a pound could sneak on every two weeks.<\/p>\n

This is not limited to wine; other studies have shown it goes for short wide glasses being perceived to hold less.  \u201cAs a result of the distortion, those given short glasses poured and consumed more than they thought, while those given tall glasses poured and consumed relatively less\u201d (Wansink p. 458). Think about that soda you may have had earlier today; do you know how many ounces that cup held?<\/p>\n

\"wide<\/p>\n

According to a French marketing professor named Pierre Chandon sourced by the New York Times writer, Tara Parker-Pope in a study including 294 subjects, participants could not accurately guess how many ounce were in various cups ranging from the standard from years ago, 6.5 ounces, to the 50 oz. \u201cDouble Gulp\u201d. Respondents guessed that the larger cups contained anywhere from 20 to 40 percent less than they actually did. Parker-Pope rationalizes, \u201cthe reason comes down to the fact that the human brain has a surprisingly tough time with geometry and often can\u2019t accurately gauge when an object has doubled or even tripled in size\u201d (\u201cMisconceptions of Soda Serving Size\u201d).<\/p>\n

The shape of that cup holding the monstrous <\/i>Big Gulp, as we know, plays a big part. Who can turn down a dollar for a 42oz thirst quencher at the local drive-thru? As consumers we are groomed to jump at the deal. Listen to the wise saying, a moment on the lips, a lifetime on the hips.  A 42 oz. Pepsi without ice is about 520 calories, that\u2019s a quarter of the daily value baseline. It may be time to hoof  it sans cup holder and ignore the drive thru altogether.<\/p>\n

Here are some ways can you do to avoid the liquid calorie booby trap<\/h3>\n

\"Fruit<\/p>\n

One easy step to avoid packing on the pounds is to switch to water. In fact, it is even better for you to drink more water and to stay well hydrated. To liven up your H2O, try adding fruit slices or refreshing herbs.<\/p>\n

If switching to water seems too difficult, try changing your glassware. Remember, participants poured and consumed less when using taller, slender glasses relative to their equal-volume, yet stout companion. This simple switch can save hundreds of calories and eventually pounds in the long run.<\/p>\n
