Het verschil tussen medisch afvallen en diëten is dat medisch afvallen wordt begeleid door een medisch professional en kan deel uitmaken van een bredere medische behandeling. Diëten is meestal een persoonlijke poging om gewicht te verliezen zonder professionele begeleiding.

Medical weight loss and diets are fundamentally different in their approach: with diets, you adjust your eating habits independently, while medical weight loss is a process involving a doctor and potentially medication to support the physical process. The biggest difference lies in the medical supervision and the biological action of the treatment. The questions below explain when each approach is suitable and what you can expect from each.

How exactly does medical weight loss work?

Medical weight loss is a supervised programme in which a doctor assesses whether medication can contribute to weight loss. The most common form in 2026 is treatment with GLP-1 medication: agents that act on hormones that regulate hunger and satiety. This causes a person to eat less without experiencing constant hunger. Results vary from person to person.

The process begins with a medical consultation. A doctor assesses the situation based on health data, weight, medical history, and any other conditions. Only after the doctor's approval is a prescription issued. The medication is then reviewed and processed by a pharmacy.

Medical weight loss is therefore not a product that you simply purchase. It is a medical process where a BIG-registered doctor independently decides whether a treatment is appropriate for that specific person. Not everyone qualifies.

What are the advantages of medical weight loss compared to dieting?

The main advantage of medical weight loss compared to dieting is that it addresses the biological causes of overweight, not just behaviour. Many people who diet experience a plateau over time or revert to old eating habits, partly because the body adapts to lower calorie intake. GLP-1 medication can break this pattern by influencing hunger regulation.

Other advantages compared to dieting independently are:

• Medical assistance a doctor follows the trajectory and adapts the approach based on the patient's situation
• Structured approach The process has a clear start, follow-up, and evaluation points
• Less dependent on willpower alone: The medication supports the process biologically, which can make behavioural change easier to sustain.
• Suitable for people with a medical indication: In cases of severe overweight or obesity, a medical approach is often more effective than dieting alone.

Dieting also has its value, particularly as a preventive measure or for mild overweight without medical complications. But for people who have already tried multiple diets without lasting success, Medical weight management another entrance.

Medical weight loss is suitable for individuals who are overweight or obese and have other health conditions that are related to their weight, such as diabetes, high blood pressure, or sleep apnoea. It is also

Medical weight loss is primarily suitable for people for whom diets and lifestyle changes have not yielded sufficient results, and for whom overweight plays a medical role. A doctor assesses on a case-by-case basis whether treatment is appropriate and responsible. There is no universal answer: suitability depends on an individual's health history, weight, medication use, and other factors.

Potential eligible individuals include:

• Individuals with a BMI above a certain threshold, depending on medical assessment
• Overweight individuals with co-existing health conditions such as high blood pressure or insulin resistance
• People who have repeatedly tried diets without lasting results
• People who struggle to stick to a strict diet due to a busy lifestyle

Individuals with certain conditions, pregnant women, or those using specific medications may not be eligible. This is precisely why a medical consultation is mandatory before a treatment is initiated.

Do you also need to adapt your lifestyle with medical weight loss?

Yes, lifestyle adjustment remains an important part of medical weight loss. Medication supports the process, but does not replace healthy eating and sufficient exercise. Treatment with GLP-1 medication works best when combined with a realistic and achievable diet and exercise pattern.

A common misconception is that medication is a quick fix where lifestyle no longer matters. In practice, people who adjust their eating habits and activity levels during the process can achieve better and more sustainable results. Medication makes this adjustment easier for many people, as it reduces feelings of hunger and increases control over eating behaviour.

Medical guidance also helps to keep expectations realistic. A doctor can explain what is achievable and how lifestyle and medication reinforce each other, without making unrealistic promises.

How safe is medical weight loss compared to popular diets?

Medical weight loss via a recognised pathway with BIG-registered doctors and certified pharmacies is safer than independently purchasing substances through unmonitored channels. In a medical pathway, the patient's health is assessed before medication is prescribed, and side effects and risks are considered in the decision.

Popular diets are generally safe when based on a varied diet, but extreme versions such as very low-calorie diets or unbalanced elimination diets can carry risks, such as nutrient deficiencies or muscle mass loss.

Prescription-only weight loss medication is never supplied in the Netherlands without a medical assessment and approval from a pharmacy. People seeking medication via foreign websites or social media run the risk of uncontrolled or fake remedies. A medical journey via a recognised provider offers a reliable alternative.

When would you opt for medical weight loss instead of a diet?

Medical weight loss is a logical step when diets have repeatedly failed to deliver the desired results, when excess weight has a medical cause, or when someone would benefit from a faster or more structured approach due to health risks. A diet is a sensible first step for mild overweight or as a preventative measure, but falls short when biological factors play a larger role.

Signs that a medical approach may be considered:

• Multiple diet attempts without lasting results
• Obesity accompanied by other health problems
• Difficulty maintaining lifestyle changes due to a busy or irregular life
• Doubt over which approach is medically appropriate for one's own situation

The choice is ultimately personal and medical. A doctor can assess whether a treatment is appropriate and which approach best suits the patient's situation.
