What food can contribute to obesity?

Common contributors include sugary drinks, sweets, fried foods, takeaway meals, refined snacks and large portions. These foods can pack substantial energy into a small amount, while drinks may add energy without making you feel as full as solid food. Obesity is influenced by many factors, including sleep, activity, medicines, stress, genetics and health conditions; one food does not explain a person’s weight.

Frequent grazing, eating quickly, or relying on highly processed foods can make hunger and fullness cues harder to notice. A balanced pattern usually includes vegetables or fruit, fibre-rich starchy foods, protein foods and unsaturated fats.

Start by noticing when and why you eat, rather than labelling foods as forbidden. Choose water or unsweetened drinks more often, serve a portion on a plate, eat without screens when possible, and add vegetables, beans, whole grains or lean protein to meals. Keep enjoyable foods in smaller portions and plan snacks if long gaps make overeating more likely.

A clinician can help review medicines, sleep, activity and related conditions alongside eating habits. Personalised support may be useful if weight changes are affecting mobility, breathing, blood pressure or blood sugar.

Arrange a medical review if weight is rising steadily, eating feels difficult to control, or you have symptoms such as loud snoring with daytime sleepiness, persistent thirst, or breathlessness. Seek urgent help for severe breathing difficulty, chest pain or sudden weakness.

Could a medicine or health condition be affecting my weight? Which eating changes fit my routine and medical needs? Should my blood pressure, blood sugar, sleep or cholesterol be checked? What support is available if I struggle with emotional eating?
