Food portion control - what does a proper food portion look like?

Food portion control

As a nation of overeaters, every day we devour an average of 200 to 300 calories more than our bodies need – partly dueto our food portions getting bigger.

Combine super-sized meals and drinks with low activity levels and the result is 61% of UK women being overweight or obese.

‘Having big portions obviously means we eat more, and it’s really easy to cook and serve out more than you need,’ says Helena Gibson-Moore, a nutrition scientist at the British Nutrition Foundation.

‘A quick check of your food portions when cooking and serving may help to save on calories – it’s all about getting the portion size right for you.’

Expert advice for reducing your food portion size

Pick up a smaller plate

If you use a huge plate or bowl, you can fill it and not realise you’re overeating. ‘Using smaller plates will help you to serve more realistic portion sizes,’ suggests Helena. ‘If you’re still hungry you can then have second helpings of the vegetables or salad, or have fruit for afters.’ You could also buy a food portion control plate to make life even easier. The one pictured below, is available on Amazon.

Snack attack

When munching away on fatty or sugary snacks, such as chocolate or crisps, make sure that you check your portion size as it’s easy to keep nibbling and nibbling on the naughty stuff . ‘It’s best to keep treats small and not have them too often. When eating a small bag of crisps or a small chocolate biscuit bar, aim to keep your intake within 100 to 150 calories,’ advises Helena.

Leave the leftovers

Resist going back for extra when you’ve finished your meal. ‘If you’ve got enough for another portion, then have it for lunch the next day or pop it in the freezer for a meal when you’re pushed for time,’ says Helen. Always making more? Try to adjust how much you cook for future meals.

Fill up on fruit and veg

‘The good news is that, provided you don’t add fat and sugars, you can have servings of most fruit and vegetables for relatively few calories,’ says Helena. Size-up on these – rather than carbs when you’re feeling extra hungry.

Perfect prep

Cooking more than you need encourages you to serve bigger portions. ‘Food such as pasta or rice expands, so can be tricky to judge,’ says Helena. ‘Weighing foods is the most accurate way to check how much to cook, but you can also use your hands or other measures.’

Mindful eating

Eating slower will help you adjust to smaller portion sizes. It takes 20 minutes for your brain to register that your stomach is full, so wait this long after you’ve finished eating before having seconds.

Cupped Palms

Small fruit, such as berries and grapes, can be piled into cupped palms. Low in calories, virtually fat-free and rich in antioxidants, blueberries and raspberries can be added to porridge or scattered over yoghurt.
