Which factor is crucial in determining weight gain or loss according to energy balance?

1. Body weight relative to height

2. Calories ingested and expended through activity

3. Usage of diuretics for calorie absorption

4. Balancing body systems beyond normal fitness

The correct answer is: Calories ingested and expended through activity

The key factor crucial in determining weight gain or loss according to energy balance is the relationship between calories ingested and calories expended through physical activity. This concept of energy balance is founded on the principle that if the number of calories consumed through food and drinks exceeds the number of calories the body uses for metabolic processes and physical activity, weight gain will occur. Conversely, if calorie expenditure surpasses calorie intake, the result will be weight loss. This relationship emphasizes that managing diet and physical activity levels is fundamental to achieving and maintaining a healthy weight. It suggests that individuals can influence their weight by either reducing their caloric intake, increasing their physical activity, or both. Understanding this balance is essential for making informed decisions regarding lifestyle choices related to nutrition and exercise.
