The scoop on supersizes
Emma Stirling APD
It’s easy to blame our supersized food supply (think jumbo muffins and whopping burgers like the ‘Quad Stacker’) for our supersized waistlines. But when was the last time you had a good look at the portion sizes you serve up at home?
It’s been estimated that we typically make around 200 decisions about food each day and many of them, sub-consciously, encourage us to overeat. Dr Brian Wansink, Director of the Cornell University Food and Brand Lab is a lead researcher in the area of eating cues and author of Mindless Eating: Why we eat more than we think. According to Wansink portion sizes have increased with time. But he’s quick to point out that a key driver is the size of our crockery. His research estimates that an oversized plate can cause you to take an extra 20% or more without knowing it. Did you know that:
- dinner plates are about 30% bigger than they were 50 years ago?
- we serve ourselves more on big plates?
- if you switch from a 12in (30cm) plate back to a 10in (25cm) plate you could lose 18 pounds (a bit over 8kg) in a year?
But surely people are just taking more food because they feel hungry? Think again. One simple but startling study by the Cornell University team involved a bottomless soup bowl that secretly refilled from under the table as people ate. Study participants were brought in for what they thought was a free lunch of soup. According to Wansink, those with re-fillable bowls ate over 70% more soup, but did not report feeling any more full or satisfied. The more startling finding was that only two out of 62 participants realised the soup was being refilled. The majority responded with – how could they feel full when they still had half a bowl of soup left? It seems that many of us have lost the art of eating to appetite satisfaction or intuitively. So what’s the solution to this modern day dilemma?

‘Change your plate first. Change your habits later,’ says Wansink: In other words, start by assessing and changing your portion and crockery sizes at home, while you work at re-harnessing your hunger cues, slowing down your eating habits and eating mindfully. Here are some great tips to get you started tackling portion distortion:
- Downsize your dinner plates from (rim to rim) 12in (30cm) to 10 in (25cm) tops. Plates with a colorful rim shrink the space to be plated with food.
- Keep a measuring cup in your breakfast cereal canister so you are not tempted to over pour.
- Switch to tall, thin glasses rather than squat glasses to give the illusion of more volume.
- Use a retractable spaghetti measure to cook just the right amount for each person.
- Pay extra attention when pouring drinks too. Such as drawing an imaginary line on that 5fl oz (150ml) mark on your wine glass.
