You may have heard people say that walking isn’t exercise, and perhaps that made you feel like it was a waste of time. That couldn’t be further from the truth. While walking may not always push your body to the limit like high-intensity workouts, it plays a crucial role in metabolism, fat loss, cardiovascular health, mental well-being, and overall longevity.
How Walking Supports Metabolism and Fat Loss
Walking may not drastically change your fitness level overnight, but it significantly impacts your body’s ability to burn fat while preserving muscle. This process, often referred to as “recomping,” is essential for long-term body composition improvements. Unlike high-intensity workouts, which can be hard on the joints, walking offers a sustainable way to stay active without excessive stress on the body.
Additionally, walking contributes to Total Daily Energy Expenditure (TDEE), which is the total number of calories your body burns in a day. TDEE is influenced by three main factors:
- Basal Metabolic Rate (BMR): The calories burned at rest, determined by age, sex, genetics, and muscle mass. It accounts for about 50-60% of your TDEE.
- Thermic Effect of Food (TEF): The energy required to digest and process food, which makes up around 10% of TDEE. Protein has the highest TEF, meaning it requires more energy to digest compared to carbs and fats.
- Activity Levels: This includes both structured exercise and Non-Exercise Activity Thermogenesis (NEAT), which accounts for 15-30% of TDEE. Walking plays a major role in this category, making it a simple yet effective way to increase daily energy expenditure.
Beyond just calorie burning, walking also improves insulin sensitivity, reduces inflammation, and helps regulate appetite by balancing hunger hormones like ghrelin and leptin. This means you’re less likely to experience intense cravings and overeating episodes. No wonder why the phrase: “Walking for weight loss” is such a popular query in google!
Walking and Longevity: The Science Behind It
Multiple studies have highlighted the significant health benefits of walking. A study published in JAMA (March 24, 2020) examined data from the National Health and Nutrition Examination Survey (NHANES) and found that:
- Individuals who walked 8,000 steps per day had a 50% lower risk of death from any cause compared to those who walked 4,000 steps.
- Those who walked 12,000 steps per day had a 65% lower risk of mortality.
- Step intensity had little impact on mortality once total step count was accounted for, but intensity still plays a role in metabolic health.
Additionally, research suggests that walking can improve cognitive function and reduce the risk of neurodegenerative diseases like Alzheimer’s. Regular physical activity increases blood flow to the brain, supporting memory retention, focus, and overall mental clarity.
Adding Intensity for Better Results
While increasing your step count is key, adding intensity can further enhance metabolic and cardiovascular benefits. A study conducted on college students with obesity examined three groups:
- Walking Step Goal Group: Aimed for 12,000 steps daily.
- Walking Exercise Group: Achieved 12,000 steps but incorporated faster-paced walking three days a week.
- Control Group: Maintained their normal routine.
Results showed that the Walking Exercise Group had superior improvements in hip circumference, visceral fat, HDL cholesterol, fasting glucose, and triglycerides, proving that a mix of volume and intensity is most effective. Incorporating uphill walking, interval walking, or brisk walking can further amplify these benefits.
Practical Ways to Increase Your Steps
If you’re wondering how to consistently hit 8,000-12,000 steps per day, here are some strategies:
- Track your steps using a FitBit.
- Park farther away when running errands.
- Take the stairs instead of the elevator.
- Get a high-energy dog that requires frequent walks.
- Break up sedentary time by taking short walks throughout the day.
- Use a walking pad while working at a standing desk. (I own this one)
- Schedule walking meet-ups instead of sitting at a coffee shop.
- Walk during phone calls instead of sitting down.
- Try walking meditation to combine movement with mindfulness.
Enhancing Your Walks with Equipment
To increase intensity, consider using a weighted vest, also known as a rucking vest. This simple addition:
- Increases calorie burn
- Improves cardiovascular fitness
- Enhances bone density
- Strengthens posture and core muscles
Rucking, a form of weighted walking that involves carrying a loaded backpack, takes this concept further. It is a highly effective way to build endurance, muscular strength, and overall fitness. Military personnel and outdoor enthusiasts have long used rucking to train for carrying heavy loads over long distances. The benefits of rucking include:
- Engaging the posterior chain (back, glutes, hamstrings) more than regular walking
- Improving grip strength and upper body endurance when using a proper ruck setup
- Providing a low-impact alternative to running while still elevating heart rate
- Strengthening the core and stabilizing muscles due to the added weight
To get started with rucking:
- Choose a sturdy backpack or a purpose-built rucksack. (I use this one)
- Start with 10-15% of your body weight and gradually increase as your strength improves.
- Maintain good posture—shoulders back, core engaged, and a steady stride.
- Walk on varied terrain to challenge stability and endurance.
Walking poles can also be beneficial, engaging your upper body and further improving stability and endurance.
Walking and Mental Health Benefits
Aside from its physical advantages, walking is a powerful tool for improving mental health. Studies have shown that regular walking reduces stress, anxiety, and symptoms of depression. Walking outdoors, particularly in nature, can enhance mood, boost creativity, and provide a sense of calm. Exposure to natural light also helps regulate circadian rhythms, improving sleep quality.
If you’re looking for ways to maximize the mental health benefits of walking, consider listening to a motivational podcast, practicing gratitude, or walking with a friend to make the experience more enjoyable.
Final Thoughts on Walking for Weight Loss
Walking is a powerful, accessible tool for improving your metabolism, body composition, cardiovascular health, and mental well-being. Aim for 8,000-12,000 steps daily, and if possible, incorporate some higher-intensity walking for additional benefits. Walking is not just about burning calories—it’s about enhancing overall well-being and longevity.
