Obesity Misconceptions: Separating Fact From Fiction

Obesity is one of the most significant public health challenges of our time. In the UK, more than 60% of adults live with overweight or obesity, and rates continue to rise. Yet despite its prevalence, public understanding of obesity remains poor. Misinformation and stigma persist - and they often prevent people from accessing the care they need.

To create a more supportive and effective approach to obesity, we must confront some of the most common misconceptions and replace them with facts. This isn’t just about improving awareness - it’s about enabling better outcomes and reducing long-term strain on healthcare systems.

It is widely assumed that obesity is the direct result of overeating and a lack of physical activity. While diet and movement do influence weight, this assumption ignores the complex web of factors that contribute to obesity.

Genetics, environment, mental health, hormonal imbalances, medication use, sleep disruption and socioeconomic status all play a role. For example, people living in areas with limited access to healthy food or safe places to exercise are more likely to experience weight gain. Similarly, long-term stress and poor sleep affect appetite-regulating hormones, which can make maintaining a healthy weight far more difficult.

This means that even when people follow similar routines, outcomes can vary greatly - and a single, simplistic explanation does more harm than good.

Linked closely to the first misconception is the idea that those living with obesity lack motivation or self-discipline. This belief not only oversimplifies the biology of weight management - it also adds a layer of stigma that actively discourages people from seeking support.

The body is designed to resist weight loss. When weight drops, the brain may trigger increased hunger and reduce resting metabolic rate - making it more difficult to maintain weight loss over time. This is a survival mechanism, not a moral failing.

For many, sustained behaviour change requires access to consistent support, coaching and understanding. A focus on willpower alone can be counterproductive, creating cycles of guilt and disappointment rather than lasting change.

Too often, obesity is viewed through a lens of appearance rather than health. In reality, it is a chronic disease recognised by both the NHS and the World Health Organization. It is associated with a significantly increased risk of type 2 diabetes, cardiovascular disease, stroke, certain cancers, liver disease, sleep apnoea and mental health conditions.

Treating obesity as a medical condition shifts the focus from aesthetics to evidence. It encourages early intervention, appropriate support and multidisciplinary care - all of which are essential to preventing long-term complications.

There is no one-size-fits-all when it comes to weight management. People have different genetic makeups, gut microbiomes, health histories, mental health needs and day-to-day responsibilities. What works for one person may not work for another.

This is why personalised approaches - based on evidence and rooted in behavioural support - are far more effective than generic advice. Programmes that consider the full context of a person’s life tend to be more successful in creating long-term, sustainable results.

Restrictive diets that promise rapid weight loss often dominate the media and the market. While these may deliver short-term results, most fail to produce long-lasting outcomes. Many of these diets are difficult to maintain and can even slow down metabolism over time, increasing the likelihood of weight regain.

Moreover, the cycle of losing and regaining weight - often known as weight cycling - is linked to a higher risk of certain health issues. Long-term success requires more than a temporary eating plan. It needs a comprehensive approach that includes behaviour change, nutrition education, emotional support and sustainable habit formation.

Weight is just one marker of health. Solely focusing on the number on the scales can obscure broader progress, such as improvements in blood pressure, blood sugar, energy levels, mood, mobility and quality of life. It may also overlook the importance of mental wellbeing - a key component in any successful health journey.

Good care takes a holistic view. Rather than chasing a target weight, the goal should be better overall health - however that looks for each person.

To make meaningful progress in tackling the obesity epidemic, we must move away from judgement and towards understanding. Every misconception we challenge is a step closer to more inclusive, effective and respectful healthcare.

Obesity is not a simple matter of choice, and the solutions are not simple either. But evidence shows what does work: tailored, person‑centred support that combines trusted clinical practice, ongoing coaching and digital tools that make care more accessible for everyone.
