Why think about portion size?
Most of us probably don’t think about portion size when we eat – it typically depends on what we would usually have, how hungry we feel and how much is in a pack or on our plate. But having a healthy, balanced diet is about getting the right types of foods and drinks in the right amounts.
Our Find your balance guide to portion size aims to help you find the right balance for you – it’s not only about eating less, its also about eating differently!
There are 3 resources you can download at the bottom of this page:
- Find your balance one page simple guide – perfect for putting on the fridge
- Find your balance booklet with example portion sizes and an example of portions for meals and snacks across a day
- Find your balance full portion list with details of portion sizes for a range of foods as well as more information and FAQs
Getting portion size right for you
We’re all individuals with different needs but for healthy adults the range of different foods we need is pretty much the same for all of us. However, the amount of food we need, varies from person to person.
The portion sizes we give are averages for healthy adults, based on a daily calorie allowance of 2000kcal – the amount estimated for an average, healthy weight, adult woman. If you’re tall or very active you may need more and could have larger portions. If you’re a small person or are trying to lose weight, you may need smaller portions. If you use the hand measures we give then portion sizes will vary with the size of your hands and so, generally, bigger people will automatically get bigger portions and smaller people will get smaller ones.
There are lots of different ways to eat a healthy diet and you can use this guidance to fit in with your preferences and beliefs – from Mediterranean, vegetarian or vegan to a more traditional British diet. It’s about balancing the food groups and finding the portion sizes that are right for you.
Finding your balance across the day
From each food group we are suggesting:
- Fruit and vegetables: 5+ portions per day
- Starchy carbohydrates: 3-4 portions per day
- Beans, pulses, fish, eggs, meat and other proteins: 2-3 portions per day
