It would depend on individual differences, age, health status, and so on.
The ability to keep fit by just walking or requiring more intense physical activity like running can vary from person to person due to several factors. These factors include:
1. Basal Metabolic Rate (BMR): BMR is the amount of energy (calories) your body needs to function at rest. It depends on various factors like age, gender, weight, and muscle mass. People with higher BMRs naturally burn more calories at rest, making it easier for them to maintain or lose weight without intense exercise.
2. Genetics: Genetics can influence a person's metabolism, body composition, and overall fitness level. Some individuals may have a genetic predisposition to burn calories efficiently, while others may have higher levels of natural physical fitness or athletic abilities.
3. Fitness level and muscle mass: Muscle is metabolically active tissue, meaning it requires more energy (calories) for maintenance compared to fat. Individuals with higher muscle mass tend to have higher metabolic rates, and therefore, burn more calories even when engaged in low-intensity exercises like walking.
4. Fitness goals and intensity of exercise: The desired fitness goals can also influence the required level of physical activity. Walking, while moderate intensity, can be sufficient for general fitness maintenance or weight management for some individuals. However, those with specific fitness goals, such as building endurance or strength, may need more intense exercises like running or other forms of high-intensity cardio.
5. Dietary habits and calorie intake: The number of calories consumed through diet also plays a crucial role in weight management and overall fitness. Even if someone walks regularly, if their calorie intake exceeds their expenditure, they might struggle to lose weight or maintain a high level of fitness.
It is important to remember that individual circumstances can vary, and what works for one person may not necessarily work for another. Consulting a healthcare professional or a fitness expert can provide personalized guidance based on individual needs and goals.
