About One You

Modern life makes it hard to be healthy

Without knowing it, by the time we reach our 40s and 50s many of us will have dramatically increased our chances of becoming ill later in life. Whether we are eating the wrong things, drinking more than we should, continuing to smoke despite everything we know, or just not being active enough, all of these small things can add up to an unhealthy you.

Making better choices today can have a huge influence on our health, and could prevent diseases such as type 2 diabetes, cancer and heart disease, and reduce our risk of suffering a stroke or living with dementia, disability and frailty in later life. But it's not easy in our busy lives – tempting treats in easy reach, bigger portions for everything we eat and technology that allows us to shop, stay in touch and be entertained without ever having to leave the sofa. Modern life is ganging up on us.

The good news is we can fight back.

One You is here to help you get back to a healthier you, supporting you to make simple changes towards a longer and happier life. One You provides tools, support and encouragement every step of the way, to help improve your health right away. You are not alone – One You can help you make small changes yourself, or with friends and family.

Take our free One You health quiz to see how you score and start the fight back to a healthier you.

400-600-600 campaign

PHE's One You campaign encourages adults, particularly those in middle age, to make changes to improve their health. The 400-600-600 campaign promotes healthier eating in particular when eating out of home. It provides a simple tip to help keep calories on track and aim for around 400 calories for breakfast, 600 for lunch and 600 for dinner. This allows for a couple of healthier snacks as part of a balanced diet of 2000 calories for women and 2500 for men each day.

This campaign is designed to provide a rule of thumb and is not a weight loss programme. The advice is aimed at the general population. It does not apply to those who are underweight. One You is unable to give individual dietary advice. If you have or care for those with special dietary requirements, medical needs, eating disorders or require specialised nutrition advice, for example if you are underweight or very overweight, we recommend that you seek guidance from a registered health-care professional.
