What shapes it
Weight

Caring for your health, not judging your body.

Weight is only one part of your health story. One common check compares your weight with your height (it is called body mass index, or BMI), and it gives healthcare professionals a first idea of where a risk might be. It cannot tell body fat from muscle, though, and it cannot show where that fat is stored. So it is read alongside your waist measurement, blood pressure, cholesterol, blood sugar, fitness, medical history and ethnic background, and never on its own.

Living with overweight or obesity, particularly carrying excess fat around the waist, can make the body work harder. It may raise inflammation, blood pressure and cholesterol, and make it harder for the body to control blood sugar, something called insulin resistance. Over time this raises the risk of coronary heart disease, where the arteries feeding the heart narrow, and of heart attack, stroke, type 2 diabetes, fatty liver disease and other long-term conditions.

Excess body fat is also linked to at least 13 types of cancer. This does not mean that everyone with a higher weight will develop cancer or heart disease. It means that their overall risk is higher.

Weight can also affect sleep, breathing, joint comfort, mobility, energy and participation in everyday life. However, body weight does not determine happiness, character or personal worth. Weight-related stigma can itself damage mental health, so care should always be respectful, supportive and free from blame.

Looking after your weight is an act of self-care, not a punishment or a search for perfection. Regular movement, nutritious food, sufficient sleep, emotional support and appropriate clinical treatment can improve health even before there is substantial weight loss. For most adults, a waist measurement of less than half their height is a useful additional goal. The BMI figures also shift for some ethnic groups, because the same risks can begin at a lower BMI.

Simple ways to reach and maintain a healthy weight

Begin with one achievable change and practise it until it feels natural.

  1. Build a balanced plate

    Half your plate vegetables or salad, one quarter protein, one quarter higher-fibre carbohydrates such as wholegrains, beans or potatoes with their skins.

  2. Choose water most often

    Replace sugary drinks, energy drinks and frequent fruit juice with water or unsweetened drinks. Liquid calories add up without making you feel full.

  3. Eat regular meals

    Skipping meals may leave you extremely hungry later. Plan regular, nourishing meals and snack only when you are genuinely hungry.

  4. Include protein and fibre

    Beans, lentils, eggs, fish, lean meat, plain yoghurt, vegetables, fruit and wholegrains help you feel satisfied for longer.

  5. Make portions work for you

    Start with a modest serving, eat slowly, and pause before having more. Stop when comfortably satisfied, not uncomfortably full.

  6. Eat with attention

    Sit down, remove screens where possible, and notice the taste, the pace and the amount. It takes time for your brain to recognise fullness.

  7. Make healthier choices easier

    Keep fruit, vegetables and nutritious snacks visible and available. Buy fewer foods that you find difficult to limit.

  8. Move in ways you enjoy

    Walking, dancing, cycling, swimming, active play and gardening all count. Build gradually and reduce long periods of sitting.

  9. Protect your sleep

    Poor sleep can affect appetite, food choices, mood and energy. Keep regular sleep and waking times, and ask for help if problems continue.

  10. Understand emotional eating

    Stress, boredom, sadness and tiredness can feel like hunger. Pause and ask: am I physically hungry, or do I need rest, comfort, movement or support?

  11. Measure progress wisely

    Notice changes in energy, fitness, sleep, mobility, waist size, blood pressure and how clothes fit, not only the number on the scales. If weighing yourself causes distress, use other measures.

  12. Plan for difficult days

    A less healthy meal or an inactive day is not failure. Return to your next helpful choice without guilt. Consistency matters more than perfection.

  13. Ask for professional support

    Medicines, health conditions, hormones, disability, mental health, genetics and social circumstances can all affect weight. Speak to your GP, practice nurse, dietitian or pharmacist.

The ISH healthy weight journey: six weeks

This is not a strict diet or a race to lose weight. It is a journey towards healthier routines, better energy and greater self-care. Choose progress, not perfection. If one day is difficult, begin again with your next choice.

Your challenge

One step at a time.

You can write your answers in as you go, and come back to them whenever you like.

Before you begin

Week 1

Drink for health

Make water your main drink. Begin each morning with a glass of water, replace sugary drinks, carry a reusable bottle, and notice how your energy and appetite feel. Add lemon, mint, cucumber or berries to make it more interesting.

Week 2

Build a colourful plate

Fill half your main plate with vegetables or salad. Eat at least two different colours at each main meal. Choose whole fruit instead of juice more often, and try one new vegetable this week.

Week 3

Find your comfortable fullness

Sit down to eat whenever possible. Put screens away during one meal each day. Eat slowly and taste your food. Pause before a second serving, and finish when comfortably satisfied rather than overfull. Take three calm breaths before your first bite.

Week 4

Move with joy

Begin with a ten-minute walk, dance or activity every day. Break up long periods of sitting, take the stairs where it is safe and suitable, and invite a friend or relative to join you. Increase gradually according to your ability.

Week 5

Plan your environment

Plan a few meals before shopping. Keep fruit and nutritious snacks where you can see them. Avoid shopping when very hungry. Serve food onto a plate instead of eating from the packet, and keep less nutritious foods for occasional enjoyment.

Week 6

Protect sleep, mood and progress

Keep a regular bedtime and waking time. Notice when stress, boredom or tiredness feels like hunger, and choose a non-food comfort: music, a walk, rest or conversation. Write down one health improvement you have noticed, and select three habits to continue.

Do I have more energy? Am I sleeping or moving better? Do I feel more in control of my choices? Which habits can become part of my life?

Important for different ages

  • Children and teenagers should focus on healthy family routines, growth and wellbeing, not unsupervised dieting.
  • During pregnancy, older age, frailty, illness or recovery, weight loss may be inappropriate.
  • If you live with an eating disorder, or a medical condition, ask a healthcare professional whether weight loss is appropriate before making major changes.

Weight is only one measure of progress. Energy, fitness, sleep, mood, mobility, blood pressure and confidence matter too.
