Should people who do not follow healthy habits pay more?

Across Europe, the rising rates of obesity and lifestyle-related illnesses are becoming increasingly difficult for healthcare systems to absorb. From the public hospitals of Spain to the insurance-based systems of Germany, the pressure is mounting—not only in terms of cost but also in how societies should approach accountability for health-related choices. One contentious proposal is whether individuals who fail to maintain healthy habits should shoulder more of the financial burden for their care.

At first glance, the rationale is clear: obesity, a major risk factor for chronic diseases, imposes significant costs on health systems. The world health organization reports that obesity has nearly tripled since 1975, now affecting over 650 million adults globally. In Europe alone, obesity is estimated to account for 7% of total healthcare costs. Proponents of financial penalties argue that this economic pressure justifies policies that make individuals more accountable, through higher insurance premiums or co-payments, for avoidable health outcomes.

Some non-european countries have taken bold steps. Japan’s “metabo law” mandates annual waistline measurements for workers, with consequences for those and their employers if thresholds are exceeded. Singapore uses a combination of penalties and incentives: those with chronic lifestyle-related diseases may pay higher healthcare costs, but citizens can also earn rewards for participating in fitness challenges. These approaches aim to promote behavior change through financial mechanisms.

However, applying such logic within the european context raises serious ethical and practical concerns. At the heart of the debate lies a tension between personal freedom and collective responsibility. While individuals are certainly the agents of their choices, many of these choices are deeply influenced by socioeconomic factors that are outside individual control. Healthier foods are often more expensive, recreational infrastructure varies widely between urban and rural settings, and access to preventive care can depend on one’s income, education, or location.

In this light, penalising people financially for unhealthy habits risks punishing those already facing structural disadvantages. Europe has long prided itself on a commitment to social solidarity and universal access to healthcare. The idea that poorer citizens, already more vulnerable to obesity due to limited options, should pay more than others undermines this ethos. Instead of bridging the health divide, such policies may deepen existing inequalities.

Effectiveness is another key issue. While financial disincentives may appear logical, their long-term impact on behavior is questionable. Japan’s waistline monitoring has had modest effects at best, with critics pointing out it does little to address underlying causes such as stress or poor diet quality. In Singapore, higher co-payments have been paired with positive reinforcement strategies, but comprehensive results on obesity reduction remain elusive. In many cases, the pressure to change may result in shame rather than sustainable transformation, particularly when biological or psychological factors, such as genetics, hormonal conditions, or mental health, contribute to obesity.

Rather than individual punishment, a more equitable and evidence-based approach lies in reshaping the environment in which people make their choices. Europe can take inspiration from its own successes in public health policy, particularly in tobacco control. The taxation of cigarettes and public smoking bans have led to significant reductions in smoking rates. Similar economic tools could be applied to unhealthy foods.

For instance, taxing sugar-sweetened beverages, processed snacks, and foods high in saturated fats has already shown promise. The United Kingdom’s soft drinks industry levy, introduced in 2018, led to a reformulation of sugary drinks and a notable drop in sugar consumption. In France, similar taxes exist, and Nordic countries like Norway have long imposed health-related food taxes. These interventions change purchasing patterns without singling out individuals for punishment.

Equally important is ensuring that healthy choices are accessible and affordable. European governments should expand subsidies for fruits, vegetables, and whole grains, while also investing in infrastructure that supports physical activity: safe walking paths, public parks, and community sports programs. Urban planning plays a major role; cities that encourage cycling, for example, contribute more effectively to public health than policies that penalise sedentary individuals.

Educational initiatives are also critical. Starting from schools, curricula must include nutrition and physical activity education that empowers young people to make informed decisions. Workplaces can also serve as vehicles for change through wellness programs and flexible schedules that allow time for exercise. These are proactive, inclusive strategies that support—not shame—people toward healthier lives.

In conclusion, while the impulse to assign personal responsibility for lifestyle-related health costs is understandable, it oversimplifies a complex issue. In Europe, where social cohesion and equity are foundational values, policies should not focus on financial penalties for individuals, especially when these may exacerbate health disparities. A more effective and ethical path lies in altering the economic and physical environment to make healthy choices the most accessible and affordable ones. By investing in preventive infrastructure, education, and progressive taxation of harmful products, European states can protect their public health systems without compromising their social conscience.
