Healthy weight

Advice and help for adults

How much we weigh is influenced by what and how much we eat, how physically active we are, our stress levels, how well we sleep and our genetics.

Weight gain can also be linked to a medical reason, find out about the nine medical reasons for putting on weight.

If you are overweight, and would like to make a change, there is a range of support available to help you on your journey to achieving a healthy weight.

Check your weight

Start by checking your Body Mass Index or BMI. This is a calculation that doctors use to see whether you are underweight, a healthy weight, or overweight. It takes into account both how tall you are as well as how much you weigh.

It's important to take weight into account: if three people all weighed 10 stone (63.5kg) but the first was 5ft (152cm), the second was 5ft 9 (175cm) and the was 6ft 2 (189cm); then the first person would be overweight, the second person would be a healthy weight and the third person would be underweight.

You can use this calculator to check your body mass index (BMI) and find out if you're a healthy weight.

Underweight?

Being underweight can be harmful to your health. If you're concerned about yourself or someone else, talk to your GP. Find advice for underweight adults.

Low mood or stress and anxiety

If you’re struggling with low mood or stress and anxiety, it can be hard to lose weight. This can be because we are more likely to reach for “comfort food” that tends to be unhealthy, and drink more alcohol.

Find information and support on improving your mental health and wellbeing.

Sleep

Some evidence shows that if you are sleep deprived, it can impact on your weight. Adults need 7 to 8 hours of sleep each night. If you are not regularly getting 7 hours of sleep a night, you may be sleep deprived.

When you’re tired, you may reach for sugary foods and caffeine to keep going. It is harder to resist unhealthy choices, and being tired impacts on the amount of physical activity that you do.

For more information and support on getting a good night’s sleep or if you are struggling with low mood, stress and anxiety, our local support services can help you .
