Understanding Healthy Weight: Small Changes and Wider Influences
Maintaining a healthy weight is not always easy, and it is not only about willpower or personal choices. Many influences outside your control can affect how easy it is to eat well and stay active.
These influences can include where you live and work, how food is advertised, food prices, opportunities for safe and affordable activity, and biology and genetics. These wider factors shape everyday habits and the options available.
Food and drink provide calories, which are units of energy. As a broad guide, adults need around 2,000 kilocalories a day for women and 2,500 for men to maintain current body weight, although needs vary greatly.
When the body takes in more calories than it uses, it stores the extra as fat. Rough guides for weight loss are 1,400 kilocalories a day for women and 1,900 for men, but age, body size, health and activity levels all matter.
Weight loss can feel difficult because the body may adapt by burning fewer calories, increasing hunger and causing more tiredness. Small, realistic changes can still have a meaningful impact over time.
Food and feelings can also be connected. Past experiences, stress and difficult times can affect eating. Some people eat to feel better when upset or to celebrate and reward themselves. If these feelings become overwhelming, speak with a healthcare professional.
A healthy weight is not only about numbers. It can help you sleep better, feel more confident and energetic, and reduce the risk of type 2 diabetes, heart disease, stroke, high blood pressure and some cancers.
Moving more, sitting less and making small changes to what you eat can benefit health and wellbeing. You do not need drastic changes to feel a difference.
Body Mass Index, or BMI, is a common tool that uses height and weight to give a general idea of whether someone is in a healthy weight range. BMI is not perfect and does not show the whole picture because muscle mass, age and body shape also matter.
