A diet asks a question the body has already answered. It proposes that eating less for a while will settle the matter, and for a few weeks it appears to, and then the weight returns bringing the reasons it left. That sequence is so consistent, across so many people in so many countries, that it is worth naming for what it is. Not a lapse of character. A physiological response working precisely as it evolved to work.
Medical weight loss starts from that fact rather than arguing with it. It treats body weight as a regulated system, with a doctor watching the regulation, instead of as a test of resolve. This article sets out what that involves in Malta: the biology, what a doctor assesses, and what a supervised course honestly looks like over three, six and twelve months.
How common is obesity in Malta?
More common than anywhere else in the European Union. Eurostat put Malta at the top of the EU in 2022 for the share of adults living with overweight, at 62.0% of people aged 16 and over, against 50.6% across the EU as a wholeSource 3: Overweight and obesity: BMI statistics. Eurostat Statistics Explained, EU-SILC 2022 reference year.. Malta also recorded the EU’s highest share of men living with obesity, at 28.7%, with the figure for women at 22.7%Source 3: Overweight and obesity: BMI statistics. Eurostat Statistics Explained, EU-SILC 2022 reference year..
Widen the frame and the pattern is regional rather than Maltese. Overweight and obesity affect almost 60% of adults and nearly one child in three across the WHO European Region, where they rank as the fourth most common risk factor for noncommunicable diseaseSource 2: WHO European Regional Obesity Report 2022. World Health Organization Regional Office for Europe..
Figures on that scale carry a specific meaning. Something affecting the majority of adults across a continent is not a set of individual failures that happen to coincide. It is a population-level condition with population-level causes.
Why is body weight regulated by biology rather than willpower?
Because the systems that set hunger, fullness and energy use run below conscious control, and they were built to defend the body against scarcity. The World Health Organization classifies obesity as a chronic, relapsing disease arising from complex interactions between genetics, neurobiology, eating behaviours, access to a healthy diet, market forces and the broader environmentSource 1: Obesity and overweight. Fact sheet. World Health Organization.. Six factors are listed. One is behaviour, and even that sits inside the other five.
Appetite is not a preference and satiety is not a decision. Both are signalled chemically, both are set differently in different people, and both shift in response to what the body has recently been through. Eating in response to those signals is not weakness. It is receiving instructions.
None of that makes behaviour irrelevant. What people eat, how they move and how they sleep all matter, and no medical care replaces them. What the biology explains is why the same effort returns so unevenly from one person to the next.
Why does the body defend a weight it has held?
Because losing weight changes two things at once, and both of them push towards getting it back: the body starts spending less energy than its new size predicts, and it feels hungrier than it did before. Neither change is imaginary and both have been measured directly.
On the energy side, adults whose body weight was held 10% or more below their usual weight showed a fall in total daily energy expenditure of about 6 kcal per kilogram of fat-free mass in people who had never been obese, and about 8 kcal in people who had. Holding weight 10% above the usual figure produced the opposite effect. The authors concluded that these compensatory changes oppose the maintenance of a body weight different from the usual oneSource 4: Leibel RL, Rosenbaum M, Hirsch J. Changes in energy expenditure resulting from altered body weight. New England Journal of Medicine, 1995;332:621-628..
On the appetite side, fifty adults with overweight or obesity who lost an average of 13.5 kg on a ten-week programme still had significantly altered levels of the circulating hormones that regulate appetite a full year later, alongside significantly increased hunger. The authors concluded that these mediators do not revert to their pre-weight-loss levels, and that long-term strategies may be needed to counteract themSource 5: Sumithran P, Prendergast LA, Delbridge E, et al. Long-term persistence of hormonal adaptations to weight loss. New England Journal of Medicine, 2011;365:1597-1604..
What does a doctor assess before treating weight?
History first, then everything that could be making weight harder to move than it should be. The assessment is a search for causes, and for anything that would make treatment unwise. On a medical weight loss pathway a Malta-registered doctor works through roughly this ground:
- The history. What your weight has done across your life, what has already been tried, what happened afterwards, and what else was going on when it moved. Patterns matter more here than any single number.
- Bloods, including thyroid function. An underactive thyroid is a common condition, and putting on weight is one of its recognised featuresSource 9: Underactive thyroid (hypothyroidism). National Health Service, UK.. It is checked rather than assumed absent.
- A review of every medicine you take. A range of medicines prescribed for entirely unrelated conditions are recognised to affect body weight, body fat distribution and metabolismSource 10: Drugs That Affect Body Weight, Body Fat Distribution, and Metabolism. Endotext, NCBI Bookshelf, National Library of Medicine.. This is a contributor almost nobody identifies for themselves, and one a doctor can sometimes do something about.
- Sleep. Short sleep is consistently associated with obesity in adults. A meta-analysis pooling 604,509 adults found an odds ratio of 1.55 for obesity among short sleepers, although the authors are careful that cross-sectional data cannot establish which way the causation runsSource 8: Cappuccio FP, Taggart FM, Kandala NB, et al. Meta-analysis of short sleep duration and obesity in children and adults. Sleep, 2008;31:619-626..
- The other conditions in play. Blood pressure, blood glucose, lipids, joints, and anything already being managed elsewhere. Weight sits inside a whole picture rather than beside it.
- What would make treatment wrong. Some histories mean medical treatment is not the right answer, and the point of an assessment is that a doctor can see that and say so.
Some of that groundwork can be done beforehand. Our BMI calculator shows the arithmetic in the open, and our calorie deficit calculator will not display a figure below the safe floor. Neither is a diagnosis. BMI in particular says nothing about muscle: it is one input a doctor weighs, not the decision.
How is medical weight care different from a diet?
A diet is a plan you follow on your own. Medical weight care is a clinical relationship in which somebody qualified is watching your measurements, what your body does in response, and whether the approach should change. The difference shows mostly when things stop going to plan.
A diet has one answer to a plateau, which is to try harder. A doctor has several, because a plateau is information: the plan may need adjusting, something in the bloods may have shifted, or the original approach may never have been the right one. Being wrong is an ordinary event inside a course of care and a catastrophic one inside a diet.
Supervision itself also produces different results from advice alone, and this is measurable. In the Look AHEAD trial, adults aged 45 to 74 with type 2 diabetes and a BMI above 25 who were assigned to an intensive supervised programme of group and individual sessions lost an average of 8.6% of their starting weight in one year, against 0.7% among those given diabetes education aloneSource 6: Look AHEAD Research Group. Reduction in weight and cardiovascular disease risk factors in individuals with type 2 diabetes: one-year results of the Look AHEAD trial. Diabetes Care, 2007;30:1374-1383.. In the Diabetes Prevention Program, a supervised lifestyle change programme lowered participants’ chances of developing type 2 diabetes by 58% over about three yearsSource 7: Diabetes Prevention Program (DPP). National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health..
Both are outcomes of a programme of care rather than of any product, and the distinction is deliberate. What a doctor may or may not prescribe, and to whom, is a clinical decision taken with a named patient inside a consultation under Maltese law. It is not something a website may advertise, and not something this page will answer for you. How the appointment itself works is set out on how it works and in our guide to seeing a doctor online in Malta.
What does a supervised course look like over 3, 6 and 12 months?
Three months is the shortest span in which the question can honestly be asked, six is where a trend separates from a fluctuation, and twelve is where maintenance becomes the actual work. Broadly, a course runs like this.
- The first month: baseline and fit. The consultation establishes where you are starting from and what will be measured. The early weeks are about whether the approach suits you, how you are tolerating it, and what needs adjusting. Very little of this month is about the scale.
- Months one to three: is this working. Enough time has passed for a direction to appear and for the first honest review. Below three months there is not enough signal to separate a real response from an ordinary fortnight, which is why three is the floor.
- Months three to six: does it hold. The question changes from whether anything moved to whether it is still moving, and bloods are rechecked where indicated. This is usually where the compensations described above make themselves felt, and where having a doctor to take them to matters most.
- Months six to twelve: maintenance. The measured energy and appetite changes are still present a year after weight loss, so holding a change is a live clinical task rather than the end of one. A twelve-month course treats that period as care.
That structure is why Carisma Medical sells weight care as a course of three, six or twelve months, with three as the minimum rather than as the cheapest option. Selling a single month would mean selling a period too short to answer the question it was bought to answer.
What does medical weight loss cost in Malta?
A consultation is €59, and the online pre-assessment before it is free. Ongoing care between consultations is €29 a month, starting only after you have been seen. As a course that comes to €146 for three months, €233 for six and €407 for twelve, and every figure is set out in full on our pricing page.
The price you see is the price you pay, including any tax. If the doctor prescribes, the medicine is a separate purchase. Collect at any pharmacy in Malta or Gozo. You pay the pharmacy directly, at its own price. We never sell or ship medicine.
You pay for the consultation whether or not the doctor decides treatment is appropriate, because the consultation is what was booked and it is delivered either way. That is what makes the decision a clinical one. A service that charged only when it said yes would have a permanent reason to keep saying yes.
When is medical weight care not the right answer?
Often enough to be worth stating before anybody books. Medical weight care suits adults whose weight is affecting their health and whose picture treatment can act on. It does not suit everybody who arrives at it, and drawing that line is part of what a doctor is for.
There is a quieter category too: people for whom the assessment finds nothing that medical treatment would improve, or finds something else to deal with first. The useful outcome of those consultations is an explanation and a direction, not a plan. A doctor who never reaches that conclusion is not being generous.
