What we choose to eat and drink has a big impact on our weight and waistline. But how much we eat and drink can have an even bigger effect.

Diabetes Victoria’s dietitian, Tim McMaster, knows that this can help to achieve a healthy weight and lifestyle. Here, he shares his best tips on how to manage portion sizes.


 Avoiding portion distortion

‘Portion distortion’ or ‘portion creep’ are two terms which we discuss quite often when we talk about our nation’s weight and waist gain. Portion distortion or portion creep refers to how we perceive the sizes of our food portions, compared to what they were like in the past. What we think of as ‘normal’ size today may very well have been thought of as a large serving in the past.

One big factor in this portion effect is the size of our plate. Next time you grab a dinner plate, use a ruler or measuring tape to see how wide your plate is. If it is wider then 25cm (10 inches), then your plate is probably too wide.

A wider plate means you can fit more food on your plate then what you actually need to eat. Compared to your grandma’s dinner set, most dinner plates and bowls today are made far too large. Choosing a smaller plate and/or bowl makes it easier to avoid serving up (and then eating) too much food.

The same issue with over-sized portions happens when we eat out. We are commonly offered the same product in a range of sizes, thinking we are getting better value for money with a larger size.

Take an unnamed fast food ‘restaurant’. When they first opened up their doors, they offered just one size of fries. Today, that same size is offered as the ‘small’ serving size providing (900 kilojoules (kJ)). Plus its menu offers two more sizes: medium (1250kJ) and large (1600kJ) which is nearly twice the amount of the original ‘small’.

What are the perfect plate portions?

Get the balance right when plating up meals at home with these simple rules:

Include some of the healthy fats in your meals, such as adding nuts into stir fry’s and salads, avocado into salads or on toast, or using extra virgin olive oil in cooking and as a salad dressing.

How to improve your portion sizes?
