Our contributor, Mary Sabat, RDN, LD, and Ace Certified Trainer, shares, “Obesity is a complex condition influenced by a variety of factors. Genetics can predispose individuals to obesity, as some people may have a genetic tendency to gain weight more easily. However, lifestyle and environmental factors play a significant role. Poor dietary habits, such as consuming high-calorie, low-nutrient foods and excessive sugar and fat intake, can contribute to obesity. Lack of physical activity is another major factor; sedentary lifestyles, characterized by prolonged periods of sitting and limited exercise, can lead to weight gain.”

She further suggests ways to manage obesity, saying, “To avoid a lifestyle that promotes obesity, it's essential to adopt healthy habits. Focus on a balanced diet rich in fruits, vegetables, lean proteins, and whole grains while minimizing processed foods and sugary beverages. Regular physical activity is crucial, incorporating both cardiovascular exercises (like walking, swimming, or cycling) and strength training to maintain muscle mass and boost metabolism. Adequate sleep and stress management are also important, as poor sleep and chronic stress can disrupt hormones that regulate appetite and metabolism. Finally, seeking support from healthcare professionals or weight management programs can provide guidance and accountability in achieving and maintaining a healthy weight.”
