A study nicknamed the Office Candy Dish looked at how our eating choices are affected by how visible and easily available particular foods are. Most of us have a candy dish lurking somewhere – where’s yours?
Dr Brian Wansink’s Study
Questions to answer:
- how does the visibility and proximity (closeness) of a food influence consumption volume?
- are proximate foods consumed more frequently because they are proximate, or are they consumed more frequently because people lose track of how much they eat?
Research methods and procedures:
- 4-week study involving chocolate candy consumption of 40 adult secretaries
- proximity – chocolates placed either on the participant’s desk or 2 m from the desk
- visibility – chocolates placed in covered bowls that were either clear or opaque
- chocolates replenished each evening
- placement conditions rotated once a week
- daily consumption noted and follow-up questionnaires distributed and analysed
So what results do you think were found?
– More visibility led to more or less candy consumption?
– Closer proximity led to more or less candy consumption?
– more candies were eaten each day when they were more visible
– more candies were eaten when they were on the desk rather than 2 m away
– there was a tendency to underestimate daily consumption of candies when on desk
– conversely, there was a tendency to overestimate daily consumption of candies when placed 2 m away
These limited results bring us no great surprises, but they do reinforce the intuitively obvious notions that proximity and visibility of a food can consistently increase a person’s consumption of it. In addition, these results suggest that people may be biased to overestimate the consumption of foods that are further away, and to underestimate those that are closer.
But so what?
Understanding the psychology in this small study can help to throw light on how best we can manage our WFPBD. It is clear as soon as you walk out of your front door that we exist in a nutritionally toxic environment, with a Pizza Hut, McDonald’s or kebab shop on every corner, and almost every supermarket aisle chocked full of sugary, fatty, largely animal-based processed junk – tempting as they may be to the taste sensors that evolution has given us.
Ensuring that we have a favourable nutritional environment in our own homes seems to make good sense.
The Motivational Triad & The Pleasure Trap
Doug Lisle PhD explains that the Motivational Triad consists of three basic humans motivations:
- avoid pain
- seek pleasure
- conserve energy
It is, therefore, not difficult to understand that we are simply acting in accordance with our evolved nature when we find it difficult to ignore the tub of ice cream looking at us with its sad eyes every time we go into the freezer to take out the bag of frozen berries; or to avoid hearing the enticing song of the cookie jar that’s loitering on the kitchen shelf next to the organic steel-cut jumbo oats. Dr Lisle calls this dilemma The Pleasure Trap.
Our bodies know full well that they can get a bigger hit of calories much more quickly from ice cream and cookies than from a bowl of berries and oats.
What wrong with a bit of self-discipline?
Of course, we can use self-discipline and will-power; but relying on these has never and will never be the best strategy for a successful and enjoyable lifetime of optimal nutrition. Sitting there and struggling with willpower every day for the next 5, 10, 20 or 50 years is not a winning proposition.
What is likely to be more successful and certainly a more pleasurable strategy is to get into mindless habits of achieving and maintaining your nutritional goals. This will then mean that you are letting the motivational triad work for you rather than against you:
- avoiding any painful sense of loss at not letting yourself indulge in foods you would rather not eat
- enjoying the pleasure of just focusing on the foods you do want to eat
- and conserving energy by making it easy on yourself to only do what is in line with your personal dietary goals
So here are a few (pretty obvious) tips[su_frame] Cookie Convenience #1 – The bad choice should always take a lot more effort. If you need to have a candy jar in the house, store it far away and out of sight – better still, remove it from the house completely.
Fridge Convenience #2 – Keep at least five healthy food options at the front part of the shelf in the fridge, especially at children’s height if you have kids and want them to eat healthily. Make it easy for you and your family to make good choices.
Recipe Convenience #3 – Make sure you have loads of wonderful recipes available, masses of attractively-stored healthy ingredients – frozen, in jars, fresh – and keep readily available all those kitchen gadgets you require to produce really tasty meals as quickly and easily as possible.
Green is Normal – Make it a normal thing to always have green leafy vegetables as a part of every single dinner. So the only choice is which greens to have.
Fruity & Attractive – Don’t stick sad-looking fruit in a dusty Tupperware bowl. Place fresh and varied-coloured fruit in a beautiful and easily reachable glass bowl.
Dishy & Attractive – When you serve up your food, make sure the serving dishes, crockery and cutlery are a pleasure to look at and use, and that the food looks appetising and colourful. Make every meal a special mindful occasion.
Safe Snacking – Keep healthy snacks easily available – fresh or (unsugared) dried fruits, nuts and seeds instead of a biscuit barrel or a tray of candies.[/su_frame]
