Is running good for losing weight?
Yes, running burns 400-800 calories per hour depending on pace and body weight, making it effective for weight loss when paired with a calorie deficit. However, diet has 3-4x more impact on weight loss than exercise alone. Running alone without dietary changes rarely produces significant fat loss.
Running is one of the most calorie-dense activities you can do: a 70kg runner burns roughly 70 calories per kilometer, so an hour of running at 6:00/km pace burns 700 calories. That's significant — more than an hour of weights, yoga, or most sports. But the weight loss math is unforgiving: 1 kg of fat equals about 7,700 calories. So even running an hour a day every day for a week only creates a theoretical 4,900-calorie deficit — less than a kilo. The bigger issue is that running makes you hungrier. Most studies show runners compensate by eating 50-80% of the extra calories they burn. For meaningful fat loss, you need both: run 3-5 times per week for 30-60 minutes AND create a 300-500 calorie daily dietary deficit through cleaner, protein-rich eating. Running alone without dietary changes usually results in body composition changes (less fat, more muscle, same weight) rather than scale movement. Start running for fitness and health; use nutrition to drive weight loss.
