Obesity is a complex, chronic health condition affecting millions of people worldwide, significantly influencing overall health and quality of life. In South Africa, the prevalence of obesity is rising, with one in eight children now classified as obese.
Understanding obesity’s causes, symptoms, and preventive measures is crucial for fostering a healthier future.
What is obesity?
Obesity is an excessive accumulation of body fat, typically measured using the Body Mass Index (BMI). A BMI of 30 or higher classifies an individual as obese. This condition results from an imbalance between calorie intake and expenditure, leading to various health complications.
Signs and symptoms.
Obesity is often identified through physical indicators such as:
- Excess body fat: Noticeable accumulation, particularly around the waist.
- Breathlessness: Shortness of breath during minimal exertion.
- Increased sweating: Excessive perspiration unrelated to temperature or activity.
- Fatigue: Persistent tiredness affecting daily activities.
Diagnosis and treatment.
Healthcare providers diagnose obesity primarily through BMI calculations and may assess waist circumference to evaluate fat distribution.
Treatment approaches include:
- Lifestyle modifications: Adopting a balanced diet and regular physical activity.
- Behavioral therapy: Counseling to address eating behaviours and emotional factors.
- Medications: Prescription drugs may be recommended to assist with weight loss.
- Surgical interventions: In severe cases, procedures like bariatric surgery might be considered.
Complications
Untreated obesity can lead to serious health issues, including:
- Cardiovascular diseases: Increased risk of heart disease and stroke.
- Type 2 diabetes: Higher likelihood of developing insulin resistance.
- Sleep apnea: Breathing interruptions during sleep.
- Osteoarthritis: Joint problems due to excess weight.
Prevention and lifestyle factors.
Preventing obesity involves:
- Healthy eating: Incorporating a diet rich in fruits, vegetables, and whole grains.
- Regular physical activity: At least 150 minutes of moderate exercise weekly.
- Behavioral changes: Monitoring food intake and setting realistic weight goals.
The truth about weight-loss “Wonder Drugs” and the Ozempic craze
In the quest for rapid weight loss, many individuals turn to so-called “wonder drugs” that promise miraculous results but often fail to deliver. There is no shortcut to sustainable weight loss, no magic pill or silver bullet. Over-the-counter appetite suppressants and unregulated weight-loss supplements frequently make bold claims but come with serious risks. These medications should never be used without consulting a doctor who understands your complete medical history, including other medications you may be taking.
Side effects commonly include gastrointestinal issues such as nausea, constipation, diarrhoea, and stomach cramps. Worse still, these drugs are rarely a long-term solution. Once discontinued, individuals often regain all the lost weight, sometimes even more, leading to a frustrating cycle of weight loss and gain, usually referred to as yo-yo dieting.
Fad diets also lure people with the promise of quick results. Still, the most effective and sustainable way to lose weight is under the professional guidance of a registered dietitian or nutritionist. If someone struggles with an eating disorder, it is essential to address the root cause with a qualified therapist rather than resorting to extreme dieting or unsafe medications.
A prime example of a weight-loss drug recently taking the world by storm is Ozempic (semaglutide). Originally developed as a treatment for type 2 diabetes, Ozempic works by mimicking a hormone called GLP-1, which helps regulate blood sugar levels and suppress appetite. While not officially approved for weight loss, many doctors are prescribing it off-label to help patients with obesity. Its sudden rise in popularity, especially among celebrities and influencers, has driven demand to unprecedented levels, sometimes even leading to shortages for diabetic patients who rely on it. However, like all medications, Ozempic is not a quick fix and should only be used under medical supervision. Long-term weight management still requires a balanced diet, exercise, and behavioral changes for lasting success.
When to consult a doctor.
It’s advisable to seek medical advice if you experience:
- Unintentional weight gain: Rapid increase in weight without changes in diet or activity.
- Associated health issues: Conditions like hypertension or elevated blood sugar levels.
- Difficulty in Losing Weight: Challenges in weight loss through traditional methods.

Early intervention can prevent the progression of obesity-related complications.
The impact of a fast-paced lifestyle on eating habits.
In today’s fast-paced world, many people are constantly on the run, grabbing whatever food is quick and convenient. Unfortunately, that often means turning to fast food, which is typically high in unhealthy fats, refined carbohydrates, and excess calories. After all, eating healthily requires planning, preparation, and mindful choices, which takes time and effort.
Comfort foods also play a significant role in our eating habits. Nothing quite like curling up in bed with a good book or a favourite TV show, mindlessly snacking on chips, chocolates, or sugary treats. Sugar, in particular, has an undeniable allure, yet we all know it acts like a toxin in the body, contributing to inflammation and fuelling various health conditions.
This highlights the importance of mindful eating, planning, and preparing meals that nourish the body rather than harm it. Sitting down at a table, savouring each bite, and chewing food properly allows for better digestion and greater satisfaction. A well-balanced meal should include lean proteins, fresh vegetables, and healthy carbohydrates, such as baked potatoes or whole grains. Incorporating good fats like avocado, olives, and nuts, which are staples of the Mediterranean diet, further supports overall well-being.
Ultimately, slowing down and being intentional about what we eat is key to long-term health. While convenience foods may fit our busy schedules, they often lead to inconvenient health consequences down the line. Prioritising nutritious, well-balanced meals isn’t just about weight management, it’s about fuelling the body for a healthier, more vibrant life.
Understanding and addressing obesity is essential for improving health outcomes and reducing healthcare system burdens. By adopting healthier lifestyles and seeking appropriate medical guidance, individuals can manage their weight effectively and lead more nutritious lives.
FAQ’s
What is the leading cause of obesity?
- Obesity results from genetic, metabolic, lifestyle, and environmental factors leading to an energy imbalance.
Can obesity be prevented?
- Yes, through a balanced diet, regular physical activity, and healthy lifestyle choices.
Is obesity genetic?
- Genetics can predispose individuals to obesity, but environmental and lifestyle factors also play significant roles.
What health problems are associated with obesity?
- Obesity is linked to heart disease, type 2 diabetes, sleep apnea, and certain cancers.
What is visceral fat, and why is it dangerous?
- Visceral fat surrounds your internal organs, such as the liver, pancreas, and intestines. Unlike subcutaneous fat (the fat under the skin), visceral fat is deeper and can be much more harmful. It has been linked to a higher risk of severe health conditions like heart disease, type 2 diabetes, and high blood pressure. Visceral fat releases harmful substances that can cause inflammation, disrupt hormone function, and contribute to insulin resistance. Managing visceral fat through a balanced diet, regular exercise, and weight loss is essential for reducing these health risks.
