The rising average weight and declining fitness levels in some countries can be attributed to several interconnected factors. One primary cause is the widespread availability and consumption of high-calorie, low-nutrient foods. Fast food, sugary snacks, and processed meals have become staples in many diets, leading to increased caloric intake without corresponding nutritional value. Additionally, sedentary lifestyles have become more common due to advancements in technology. Many people spend significant portions of their day sitting at desks, using computers, or engaging in passive entertainment like watching television.
