1. Poor Diet and Overeating
Identified cause:
A diet high in calories, sugar, unhealthy fats, and processed foods is one of the primary causes of obesity. Portion sizes have also increased significantly, contributing to excess calorie intake.
Prevention Tip:
Choose whole foods, reduce sugar and refined carbs, and pay attention to portion sizes. Meal prepping and mindful eating can also help reduce overeating.
2. Lack of Physical Activity
Identified cause:
Modern lifestyles often involve minimal physical movement, especially with desk jobs, elevators, and cars. Low physical activity leads to fewer calories burned, causing fat buildup over time.
Prevention Tip:
Aim for at least 30 minutes of moderate exercise daily. Walking, cycling, swimming, or even dancing can keep your metabolism active and help prevent obesity.
3. Genetics and Family History
Identified cause:
Genes influence how your body stores fat, burns calories, and regulates appetite. If obesity runs in your family, you may have a higher risk.
Prevention Tip:
Genetics is not destiny. Stay consistent with healthy habits, monitor weight regularly, and seek support from professionals if needed.
4. Hormonal Imbalances
Identified cause:
Conditions like hypothyroidism, polycystic ovary syndrome (PCOS), and insulin resistance can disrupt metabolism and fat storage, leading to weight gain.
Prevention Tip:
Consult a healthcare provider for proper diagnosis and management. Balanced nutrition and medication (if needed) can help control hormone-related weight gain.

5. Sleep Deprivation
Identified cause:
Insufficient sleep disrupts hunger-regulating hormones like ghrelin and leptin, increasing cravings for unhealthy food.
Prevention Tip:
Aim for 7–9 hours of quality sleep each night. Establish a consistent bedtime and avoid screens before sleeping.
6. Stress and Emotional Eating
Identified cause:
Chronic stress leads to emotional eating and higher levels of cortisol, a hormone that promotes fat storage, especially around the abdomen.
Prevention Tip:
Practice stress-reducing techniques such as meditation, yoga, or journaling. Keep healthy snacks on hand and recognise emotional eating triggers.
7. Medications
Identified cause:
Certain drugs—like antidepressants, steroids, and antipsychotics—can lead to weight gain as a side effect by affecting appetite or metabolism.
Prevention Tip:
Discuss side effects with your doctor. They may adjust the dose or recommend alternatives that are less likely to cause weight gain.
8. Medical Conditions
Identified cause:
Diseases such as Cushing’s syndrome, hypothalamic injury, and certain metabolic disorders can lead to obesity.
Prevention Tip:
Regular checkups can catch medical issues early. Treating the underlying condition is key to managing weight effectively.

9. Sedentary Lifestyle
Identified cause:
Sitting for long hours, minimal movement throughout the day, and screen addiction contribute to fat accumulation and slow metabolism.
Prevention Tip:
Incorporate movement into your day—use standing desks, take short walking breaks, and limit screen time where possible.
10. Environmental and Social Factors
Identified cause:
Lack of access to healthy food, exposure to fast food marketing, and social circles with poor health habits can encourage obesity.
Prevention Tip:
Create a healthy environment at home, surround yourself with health-conscious people, and make nutritious food more accessible in your daily life.
