Obesity explained
Obesity simply means carrying more body fat than is healthy for your frame — typically defined in the UK as having a Body Mass Index (BMI) of 30 or above. But that one-line definition barely scratches the surface. Obesity isn’t a character flaw or a lack of willpower; it’s a complex condition shaped by genetics, hormones, gut health, sleep, stress and the food environment we all live in. The encouraging news is that, for most people, it’s also something that can be gently and sustainably improved — not through punishing diets, but through working with your body rather than against it.
Are you ready to take control of your health and tackle obesity-driven diabetes head-on? In this engaging 45-minute webinar recording, we share practical, proven tips for preventing and managing diabetes linked to excess weight.
What Exactly Is Obesity?
In the UK, obesity is generally measured using BMI, a simple calculation based on your height and weight. A BMI between 18.5 and 24.9 is considered a healthy weight, 25 to 29.9 is overweight, and 30 or above is classed as obese. It’s a useful starting point, but it’s far from perfect — BMI can’t tell the difference between fat and muscle, and it says nothing about where your weight is carried.
That last point matters enormously. Fat stored around the middle, known as visceral fat, behaves very differently to fat stored on the hips or thighs. It sits close to your organs, releases inflammatory signals, and interferes with how your body manages blood sugar. This is why waist circumference is often just as telling as the number on the scales.
Why Does Obesity Happen?
It’s tempting to boil obesity down to ‘eating too much, moving too little’, but the reality is far more layered. Several factors tend to work together over time.
Lifestyle and Environment
Modern life makes weight gain easy. Convenience foods are everywhere, portion sizes have crept up, and many of us move far less than our bodies were designed to. None of this is a moral failing — it’s simply the world we live in, and recognising that takes the shame out of the conversation.
Hormones and Metabolism
Hormones such as insulin, cortisol and leptin all play a role in how your body stores and releases fat. When these fall out of balance — often due to chronic stress, poor sleep or blood sugar swings — the body becomes more inclined to hold onto weight, regardless of how disciplined someone is with food.
Gut Health
Emerging research increasingly points to the gut microbiome as a quiet but powerful influence on weight. A diverse, fibre-rich diet supports the kind of gut bacteria associated with healthier metabolism, while heavily processed diets tend to do the opposite.
Sleep and Stress
Poor sleep disrupts the hormones that control hunger and fullness, often leading to stronger cravings for sugary, high-carbohydrate foods. Chronic stress raises cortisol, which can encourage the body to store fat around the abdomen. Addressing these two areas is often as important as anything on the plate.
Why Obesity Matters for Your Health
Carrying excess weight, particularly around the middle, raises the risk of several long-term health concerns, including type 2 diabetes, high blood pressure, joint problems and cardiovascular strain. The good news is that this risk isn’t fixed. Research, including the UK’s own DiRECT trial, has shown that losing just 5 to 10% of body weight can meaningfully improve blood sugar regulation and overall health — you don’t need to reach an ‘ideal’ weight to feel the benefits.
A Gentler Way Forward
Rather than chasing quick fixes or restrictive diets, lasting change tends to come from small, consistent shifts that support the body’s natural balance.
Nourish, Don’t Restrict
Focus on whole, minimally processed foods — vegetables, legumes, good quality proteins and healthy fats. These keep blood sugar steady and naturally reduce cravings, without the need for strict calorie counting.
Move in Ways You Enjoy
Exercise doesn’t need to be intense to be effective. Regular walking, swimming or gentle strength work all improve insulin sensitivity and support a healthy metabolism. Consistency matters far more than intensity.
Prioritise Rest and Calm
Aim for seven to nine hours of good-quality sleep, and find small ways to manage stress — whether that’s time outdoors, breathwork or simply slowing down. Both have a far bigger impact on weight than most people realise.
Support Your Gut
A varied, fibre-rich diet feeds beneficial gut bacteria, which in turn supports healthier digestion, steadier blood sugar and, over time, a more balanced weight.

The Bottom Line
Obesity isn’t simply about willpower — it’s a layered condition shaped by lifestyle, hormones, gut health, sleep and stress. Understanding this takes away the guilt and opens the door to a kinder, more sustainable approach. Rather than fixating on a number on the scales, focus on building habits around food, movement, rest and stress that genuinely feel good — because that’s where lasting change really begins.
