Why can losing weight without medication sometimes be unsuccessful?

Losing weight isn't always successful despite serious effort, and there's often a biological explanation for this. The body possesses mechanisms that actively counteract weight loss, regardless of how much someone tries with dieting or exercise. This article answers the most frequently asked questions about why losing weight is so difficult and when medical guidance can be a more realistic option.

What makes losing weight biologically so difficult?

Losing weight is biologically difficult because the body perceives weight loss as a threat and actively compensates. Hormones such as leptin and ghrelin regulate hunger and satiety, and during weight loss, this system shifts in a way that promotes increased appetite and reduced energy expenditure. This is not a lack of willpower, but a physiological response.

The human body is evolutionarily programmed to store energy, not to lose it. When someone eats fewer calories, the metabolism slows down to limit energy loss. At the same time, hunger increases. This phenomenon, also known as Adaptive thermogenesis called, makes it progressively harder to lose weight the longer a diet lasts.

Insulin resistance also plays a role in people who are overweight. Cells become less responsive to insulin, which increases fat storage and reduces fat burning. This creates a cycle that is difficult to break without a targeted approach.

What factors cause diets to fail?

Diets often don't work in the long term because the body adapts to a lower calorie intake, and most diets are not sustainable in daily life. Besides biological adaptation, lifestyle, stress, and lack of sleep play a significant role in the failure of dieting attempts.

A number of factors that contribute to diet failure:

• Chronic stress increases cortisol levels, which promotes belly fat storage and increases appetite.
• Sleep deprivation disrupts the hormone balance and increases the craving for calorie-dense food.
• Irregular eating pattern A busy work schedule makes consistent nutritional choices more challenging.
• Jojo effect Following repeated dieting attempts, metabolism changes in a way that makes future weight loss more difficult.
• Social and environmental factors such as eating out or social pressure undermine the best intentions.

People who do not achieve lasting results despite multiple serious attempts are not alone in this. Science confirms that long-term weight loss without support is difficult to achieve for many people.

When is losing weight without medical help not realistic?

Losing weight without medical assistance is less realistic for someone with a BMI over 30, who has had multiple failed attempts, or when the excess weight is associated with health problems such as type 2 diabetes or high blood pressure. In these cases, a medically supervised programme is often more effective than independent lifestyle interventions.

There are situations where losing weight independently is structurally unsuccessful, not due to a lack of motivation, but due to underlying factors that a doctor must assess. Consider hormonal conditions such as hypothyroidism, medication use that has weight gain as a side effect, or a metabolism that has become disrupted by repeated dieting attempts.

When someone has been struggling for years with weight loss and if the usual approach does not yield results, it makes sense to investigate whether there is a medical explanation and whether treatment with medication might be a suitable option. This is always a decision made by a doctor based on the individual situation.

GLP-1-medicatie, zoals semaglutide en liraglutide, werkt op verschillende manieren om gewichtsverlies te bevorderen. **Hoe het werkt:** 1. **Hormoonnabootsing:** GLP-1 (glucagon-like peptide-1) is een natuurlijk hormoon dat in je lichaam wordt aangemaakt na het eten. Deze medicijnen bootsen de werking van dit hormoon na. 2. **Appetijtregulatie:** * **Vertraagde maaglediging:** Ze vertragen de snelheid waarmee voedsel je maag verlaat, waardoor je je langer vol voelt na een maaltijd. * **Signalen naar de hersenen:** Ze sturen signalen naar de hersenen die het hongergevoel verminderen en het verzadigingsgevoel vergroten. Dit betekent dat je minder trek hebt en sneller verzadigd bent, wat leidt tot een lagere calorie-inname. 3. **Bloedsuikerregulatie:** * **Insulineafgifte stimuleren:** Ze stimuleren de afgifte van insuline wanneer de bloedsuikerspiegel hoog is, wat helpt de bloedsuikerspiegel te verlagen. * **Glucagonproductie remmen:** Ze remmen de afgifte van glucagon, een hormoon dat de bloedsuikerspiegel kan verhogen. Dit helpt ook bij het stabiel houden van de bloedsuikerspiegel. Hoewel dit primair gericht is op diabetesbehandeling, draagt een stabielere bloedsu

GLP-1 medication works by mimicking a hormone that occurs naturally in the body and plays a role in regulating appetite and blood sugar. It makes people feel fuller more quickly and for longer, which naturally reduces calorie intake without constant hunger.

GLP-1 stands for glucagon-like peptide-1, a hormone that is released after eating and sends signals to the brain that sufficient food has been consumed. Medication that mimics this hormone also slows stomach emptying, which contributes to a longer-lasting feeling of fullness.

It is important to note that GLP-1 medication is not a substitute for a healthy lifestyle, but rather a support for it. Results vary from person to person and depend on multiple factors, including diet, exercise, and individual response to the medication. A doctor assesses on an individual basis whether this treatment is suitable and medically appropriate.

Is medication for weight loss safe and who is it suitable for?

Weight loss medication can be safe when prescribed and supervised by a doctor who assesses the individual situation. Not everyone is eligible: a medical intake is necessary to determine if the treatment is appropriate and if there are any contraindications.

GLP-1 medication is prescription-only in the Netherlands, meaning a doctor must issue a prescription after assessing the patient's health situation. This is a deliberate protective measure: the medication has side effects and is not suitable for everyone.

Possible side effects include nausea, stomach upset, and fatigue, particularly in the initial phase. A doctor will weigh these risks against the expected benefits based on the individual's situation. People with certain conditions or who are using specific other medications may not be eligible.

Buying medication through non-certified foreign websites or social media carries serious risks. The quality and composition of such medicines are not guaranteed, and there is no medical supervision. A reliable process always goes via a BIG-registered doctor and a certified pharmacy.

How do you start a medically supervised weight loss programme in the Netherlands?

A medically supervised weight loss programme in the Netherlands begins with a medical intake where a doctor assesses the health situation and determines if treatment is appropriate. Following approval, the doctor will issue a prescription which is processed through a certified pharmacy and discreetly dispatched.

The process takes place in a number of steps:

1. Filling in a medical questionnaire about health, medication use, and weight history.
2. Assessment by a BIG-registered doctor, who independently decides whether treatment is appropriate.
3. Upon approval: prepare a prescription and send it to the collaborating pharmacy.
4. The pharmacy independently reviews and processes the delivery.
5. Medication is delivered discreetly to your home, with the option for a subscription for repeat deliveries.

Not everyone who completes an intake form will be eligible. The doctor decides on a case-by-case basis, taking into account the medical situation. Transparent pricing information upfront allows for an informed decision to be made before the treatment begins.
