How big should your lunch really be?

Alongside the important question of “what do I want for lunch?” is the second most important question: “how big should it be?” Turns out, Aussies are suffering from a case of portion distortion. Here’s our guide to getting it right, every time.

Lunch portion sizeThe first rule of portion sizes: the size of your plate matters! Research from Deakin University found that simply doubling the size of your plate leads to a 44% increase in how much you eat, on average. This is alarming, considering data suggests our plate sizes have increased by 36% since 1960 ­­– so we could be upsizing our lunch by accident.

To further complicate things: our portion sizes in Australia are growing. New research from the George Institute of Global Health found in Australia, the portion sizes for discretionary foods have increased by up to 66% since 1995. And that’s just for treat food like pizza, cake, ice-cream and wine.

So if we can’t rely on the size of our plate or our serving sizes, how do we find the correct portion for breakfast, lunch and dinner? Here’s an easy base guide, which can be adjusted depending on your goals:

Start with two closed hands of non-starchy vegetables with each meal. E.g. leafy greens, broccoli, capsicum, carrots, mushrooms and tomatoes. This should make up most of the plate. Add one palm-sized portion of protein with each meal. E.g. chicken, beef, lamb, pork, eggs and seafood. People who need more protein generally have a larger hand! Add one cupped hand size of smart carbs with each post-workout meal. E.g. sweet potato, brown rice and chickpeas. Adjust depending on your level of activity. Cook or garnish meals with healthy fats, like olive oil and macadamia oil. You could also add avocado, nuts or seeds, to taste. This translates to about 2/3 of your plate filled with non-starchy vegetables, 1/3 of your plate with quality protein, then smart carbs and healthy fats on top.

“It might seem like a lot of veggies to start off with, but people should concentrate on working their way up to this,” explains THR1VE Nutritionist Shannon Young. “With reduced servings of carbs and protein, there’s plenty of room for fresh vegetables. If you concentrate on a range of coloured veg, it’s a fantastic way to get all your vitamins and minerals, as well as fibre.”

For a good example of a healthy portion, take a look at the THR1VE fresh ready meals. “We have designed our THR1VE meals so that they are perfectly portioned. You can then select certain meals based on your dietary requirements,” says Young. “E.g. someone training might add a protein shake or select a post-training meal online.”

Our ready-made meals may sometimes seem “smaller” than your average offering, but the reality is they’re just the right portion of quality ingredients. “Lots of fast food companies use cheaper, poor quality ingredients to bulk up a serving size,” explains Young. “This means when people do receive a smaller portion of good quality food they feel like they are being ripped off when really it is enough food to satisfy!” The take-away: you can always upsize your portion of good quality veggies – then keep the rest in check.
