Most of us know that we should eat in the two breaks we get during GMAT to replenish our energy. An often asked question is the kind of snacks you should consume.
Check out this post by David which discusses this point: https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/2013/03 ... at-scores/
Let me quote two important points he mentions in his article:
- Whether or not to consume caffeine varies from person to person, however, one thing that does not vary is that sugar before the test and during each break is an important part of your snack. Research reported in the New York Times indicated that making tough decisions (this is what the GMAT is all about!!!) leaves you depleted. The one thing that brings you back to life? A Sugary snack. 100 calories is enough but just make sure it is sugary!
- Please no experimenting with energy drinks! It is not energy drinks that you need – what you need (strangely enough) is sugar. In experiments done by psychologists (and reported in the New York Times) it is sugar that can take away the mental fatigue. About 20 minutes after having a sugary snack, participants were better able to make decisions again. So NO!!! to fake energy drinks that will just likely make you jittery. Now if coffee is your daily routine, then keep your normal routine, but if you do not drink coffee normally then do not do so on test day.
Here is the link to the NY Times article he quotes: https://www.nytimes.com/2011/08/21/magaz ... d=all&_r=0
(A mighty long but fascinating read)
That's a silver lining to the GMAT exam - you get to break open your candies, cookies or cupcakes! (or you could go for the healthier fruit option - tangerines, cherries, grapes, mangoes, figs, bananas, pomegranates )

I always love your perspective on the GMAT, Karishma, but I have to respectfully disagree with your advice in this case.
Unfortunately, pure sugar is arguably the worst thing a test-taker can consume prior to a four-hour exam, simply because it causes a crash afterwards. Yes, your brain desperately needs sugars (usually in the form of glucose) to function, but to succeed on a four-hour exam, your brain needs a nice, steady supply of energy. Sugary snacks cause a quick spike in glucose and insulin levels... and then a very speedy crash.
(A fun cautionary tale: back when I taught high school, one of my students ate a massive bag of Skittles before his SAT exam. He confidently ripped through the first section... and then literally fell asleep during the middle of the second section. Oops.)
I can see how the New York Times article could cause a little bit of confusion, though. All of the experiments in the article mentioned glucose (a relatively pure form of simple sugar), but the article didn't fully explain that our bodies ultimately break all carbohydrates down into glucose. If you consume pure glucose (or fructose or dextrose or any other closely related simple sugar), minimal digestion is required, and the glucose will rapidly work its way through your body. You'll get a wonderful spike, then an inevitable crash. But if you consume balanced foods that contain a nice mix of proteins, fats, and complex carbohydrates, your body will slowly break them into glucose, and your brain will receive the steady supply of the energy it needs for a four-hour GMAT marathon.
The New York Times piece buried this little nugget deep in the article:
I hate to be the bad guy who discourages cupcake binges, but the sugary snacks are only useful if you need a very short-term glucose spike. The safer way to keep your brain consistently fueled is to eat foods that offer a nice mix of proteins, fats, and complex carbohydrates--a high-protein energy bar (such as Clif Builder bars or Think Thin bars or Balance bars) or a small sandwich on whole grain bread, for example. If you're familiar with the glycemic index (GI), then look for low GI foods for your breaks and pre-test meals.
Would it be possible to survive a GMAT exam on a diet of M&Ms and Jolly Ranchers? Sure--some people metabolize sugars more slowly than others, and some people will do just fine as long as they continue to inhale candy during their breaks. But for most of us, the best way to ensure a steady glucose supply to our brains is to avoid simple sugars, and eat balanced (and probably less appealing!) foods that contain a good mix of macronutrients.
