Understanding your weight, and what actually helps.
Weight is a health issue, not a willpower issue. Our GPhC-registered pharmacy is led by an award-winning obesity specialist pharmacist, and our clinicians specialise in weight management — so you get clear, honest information, the full range of options explained, and support built around what works in the long term, not just the first few months.
Whether you're an adult looking for treatment, or a parent seeking help for a young person aged 12–17, there's a dedicated route for you.
It's not about willpower — and you're far from alone
Across the UK, around two in every three adults are above a healthy weight, and roughly one in three is living with obesity. If this is something you're dealing with, it's genuinely common, and there's a lot that can help.
adults across the UK are overweight or living with obesity — 66% in England and Scotland, 67% in Northern Ireland, 62% in Wales.
of adults in England, Scotland and Northern Ireland are living with obesity.
England 30% · Scotland 32% · Northern Ireland 30% living with obesity. Wales reports 62% overweight or obese combined.
Latest available national surveys: England 2024, Scotland 2023, Northern Ireland 2024/25 (all measured height and weight); Wales 2024–25 (self-reported, which tends to underestimate true levels). Figures aren't directly comparable between nations.
The World Health Organization (WHO) recognises obesity as a chronic disease
Not a matter of trying harder. Your weight is shaped by things largely outside your direct control — your genes, your hormones, the environment you live in, even medications you might take for something else. Blaming willpower alone doesn't match what the science actually shows.
Two different situations, treated differently
For some people, excess weight has already started affecting how their body works — joints, breathing, blood sugar. For others, weight is a risk factor that hasn't caused problems yet. These call for different levels of support, which is exactly why we start with a proper conversation, not a number on a scale.
BMI and waist-to-height ratio
Two simple, well-established measures — used together, because BMI alone doesn't tell the full story. This is a starting point for a conversation, not a diagnosis.
Your results will appear here once you enter your height and weight.
- Below 18.5Underweight
- 18.5 – 24.9Healthy weight
- 25 – 29.9Overweight
- 30 and aboveObesity
BMI thresholds are population averages and may not apply equally to everyone — for example, health risk can appear at a lower BMI in some South Asian, Chinese, and other ethnic groups, and BMI doesn't distinguish muscle from fat, which matters for very muscular individuals or older adults with reduced muscle mass. Waist-to-height ratio adds a useful second measure: as a general rule, aiming to keep your waist circumference below half your height is associated with lower health risk. Neither measure diagnoses clinical obesity on its own — that requires a fuller clinical assessment, which is exactly what a consultation with us involves.
A spectrum of care, not a single path
Treatment isn't one-size-fits-all, and it isn't just about medication. Here's how the full range of support fits together.
-
Foundation: lifestyle and behavioural support
Structured, sustainable changes to nutrition, movement, sleep, and stress — the basis of every effective plan, regardless of what else is involved. This isn't about willpower; it's about building habits that fit your actual life.
-
Structured specialist support
Where lifestyle change alone hasn't been enough, more intensive, multidisciplinary support — dietetic input, psychological support, structured programmes — often makes the difference. This is where most people benefit from professional guidance rather than going it alone.
-
Medical treatment, where clinically appropriate
Prescription treatment options exist and can be highly effective for the right person, assessed individually.

We support weight maintenance, not just weight loss
Losing weight and keeping it off are genuinely different challenges — your body actively resists weight loss through hormonal and metabolic changes. That's exactly why our care doesn't stop once weight comes off: maintaining your results is treated as its own, ongoing phase of support, not an afterthought.
If you're on medical treatment
Reaching your effective dose isn't the finish line — it's the point where the real, ongoing work of maintenance starts. Most people need to stay on treatment, at some dose, for it to keep working. This isn't a sign anything's gone wrong; it's simply how the biology of weight regulation works.
What the evidence actually shows
In the STEP 1 trial — one of the largest studies of its kind — people who stopped GLP-1 medicine after 68 weeks of treatment regained roughly two-thirds of the weight they'd lost within a year of stopping. This isn't a failure of willpower; it's a well-documented, expected biological response, and it's exactly why any decision to reduce or stop treatment needs to be planned with us, not made alone.
Three phases, all supported
-
Maintaining on treatment
Once you're at an effective dose, the goal shifts from losing weight to holding steady — regular reviews, monitoring for side effects, and keeping the lifestyle habits that make the medicine work best.
-
Titrating down, if appropriate
For some people, once habits and results are well established, a gradual, clinically supervised dose reduction can be considered — never a decision to make on your own, and never guaranteed to hold results.
-
Stopping, with a real plan
If and when stopping is right for you, we plan for it — reinforcing lifestyle support in advance, setting expectations honestly using the evidence above, and monitoring closely afterwards rather than leaving you to manage the transition alone.
General principles that apply either way
Ongoing, not a destination
Like managing blood pressure or diabetes, weight management usually works best as continuous care — regular check-ins, not a one-off programme with an end date.
Setbacks are normal, not failure
Weight regain is a common, expected response — not evidence that something went wrong or that you didn't try hard enough. What matters is having support to get back on track.
Sustainable beats extreme
Approaches you can actually maintain — realistic eating patterns, movement you enjoy — consistently outperform anything drastic or short-term in the research on long-term outcomes.
Monitoring matters
Regular, appropriate check-ins — not obsessive self-weighing — help catch drift early and keep your plan working for you, especially if you're using medical treatment.
Your mental health counts too
How you feel about your body and your relationship with food matters as much as the number on the scale — and is part of what genuinely sustainable care addresses.
Support shouldn't stop
Whatever combination of treatment got you here, staying connected to that support — rather than being discharged the moment a target is hit — is one of the strongest predictors of keeping results.
Adults and young people, both properly supported
Weight is often a family matter — which is why we built dedicated, age-appropriate care for both.
