Weight & obesity
When weight starts affecting health — blood pressure, blood sugar, joints, sleep, energy — it becomes a medical issue that deserves medical support, not just willpower talk.
Medically reviewed by Dr [GP Name], General Practitioner GMC 0000000
Why it happens
Weight is regulated by biology as much as behaviour — appetite hormones, genetics, sleep, medicines, stress and environment all push on it. That’s why "eat less, move more" alone fails so many people, and why modern treatment targets appetite biology directly.
Treatment
Clinician-led programmes combine structured lifestyle change with, where clinically appropriate, modern appetite-regulating medicines — prescribed only after proper assessment and with ongoing monitoring. Not everyone is suitable, and a good service says so.
Self-care that helps
A sustainable calorie deficit, protein and fibre at each meal, strength training twice weekly, 7+ hours of sleep, and limiting alcohol and liquid calories. Small consistent changes outperform dramatic short-lived ones.
When to get help
If sustained lifestyle change hasn’t shifted health-affecting weight, or you have symptoms like chest pain or severe breathlessness, seek clinical assessment.
