Dieting hacks: optical illusions & outta sight, outta mind

A lot of what we eat, sizes we choose, and amounts we serve ourselves are just an illusion. What do I mean by this?

Studies have shown that the most popular drink serving size is medium. However, “medium” is varies from restaurant to restaurant. For example, did you know Starbucks has a “short” size? It’s true. But they don’t advertise it because if they did, they know they would sell mostly “tall” drinks instead of “grande” which in most people’s eyes is considered their “medium” size. Why? Because they advertise tall-grande-venti. If they advertised short-tall-grande, we would all want tall. Interesting, huh?

To drive home this point, the first time I went to my local movie theater, I got a medium soda. However, what they considered medium was about 42 ounces!!! I took my kids yesterday and remembered this, so I ordered a “small” 32 ounces. Still gigantic, but imagine how many people are ordering the 42 ounce sodas simply because of the “medium” label? In a gas station, we call those “big gulps.”

I haven’t been to a bar in a long time….make that about 8 years (about the age of my oldest plus 9 months.) But in study found that experienced bartenders will pour about 20% more alcohol into a short glass versus the same size tall glass if not pre-measured while the average person will pour around 30% more. You think restaurants and bars have more tall glasses because of this? Of course they do! Or at least they are required to use their jiggers! Try this concept with your children for fun: show them 1/2 cup candy in a tall glass and a short glass (clear, see through) and give them a choice. They will choose the tall glass even though its the same amount. Why? Because the tall, slender glass looks like more candy.

How can you apply the optical illusion concept to your life?

  1. Use smaller bowls, plates, and cups so that it appears as if you are eating more than you are. As referenced in my last post, those portions will get lost in large plates and it’s been proven over and over, you will eat more if you eat on large serving dishes.
  2. Divide your snacks into smaller portions. The same researcher mentioned above, found that using visual indicators significantly reduces the amount that we eat. Check out this study where just adding a different color every seventh or fourteenth chip resulted in a 250 calorie difference!! It really can be that easy, folks! This is why single serving and 100 calorie packs are so effective! Get yourself some snack-sized plastic baggies and pre-portion out your snacks or before you sit down to watch television with a bag of chips, put a handful in a bowl first so you can see what you are eating. Do not rely on estimates when you are eating directly from the bag. Take that extra step if you are serious about losing weight.
  3. Make it inconvenient to overeat and put foods you should be limiting out of sight. Remove the candy dish off your desk and put it somewhere you can’t see it (like, in the trash. No really, in the pantry). Get the bag of chips off the top of your refrigerator and put it behind closed cabinet doors. Store your leftovers in an opaque container, in the back of your refrigerator (I don’t care if you forget about them, that’s the kind of the point!) And please, stop storing that ice cream in the freezer in case your grandkids come visit! It’s not good for them, either!
  4. Keep healthy foods convenient and visible. Store fresh fruits and vegetables in clear containers, in the front of your refrigerator, already cut up and ready to eat. Purchase cheese sticks already portioned out and make sure they aren’t buried under stuff in the deli drawer. Boil eggs in advance and peel them so that they are ready for a snack when you’re hungry, again stored in a clear container where you can see them. Replace the cookie jar on the counter with a bowl of fresh fruit. Put some single serve trail mix packages on top of your fridge in place of the chips. Need proof this stuff works? Here’s another study for you on how out of sight, out of mind reduces over-eating- office workers ate 5.6 more chocolates each day when dishes were visible but inconvenient, and 2.9 more chocolates when dishes were convenient but not visible. I’m suggesting you do both (make the food inconvenient and invisible), but according to this study, it’s the visibility that really counts.

Even if you pick one or two of these hacks to try, I think you will see some results in your life. Let me know in the comments what you try and how it’s helping you. Remember, it’s not willpower, it’s skill-power. I’m going to keep emphasizing that point because I want you to understand that you have the power within yourself to see the results that you desire.
