Portion control is a vital part of weight management. That's because no matter how healthily you eat, you can still put on weight if you're eating too much of any sort of food. Food serving sizes today are far bigger than they were 30 years ago (apart from chocolate) - this means we're consuming a lot more calories than we use. In fact, many of us no longer know what makes a normal portion - a problem known as portion distortion. There’s lots of advice and information about the importance of portion control, what it means and how to fit it into everyday life on our portion control pages.
