Every January, gym floors fill with new runners and by mid-February most have quietly shelved the trainers. The problem is rarely motivation. It is that running is a poor starting tool for fat loss in an untrained body. Walking, unglamorous as it sounds, does the job better for most people. Here is the honest comparison.<\/p>\n
A 75kg adult running at 10km\/h burns around 600 kcal per hour<\/strong>. The same person walking at a brisk 5.5km\/h burns around 280 kcal per hour<\/strong>. On paper, running is the clear winner.<\/p>\n Except almost nobody runs for an hour. Most new runners manage 20 to 30 minutes, two or three times a week, before something niggles.<\/p>\n Fat loss is a twelve-month project, not a six-week one. What actually matters is the total calories you burn across a month, and that depends on how often you show up.<\/p>\n An hour of brisk walking, five days a week, burns roughly 1,400 kcal. Three 30-minute runs burn around 900 kcal. Walking wins the monthly total for most people.<\/p>\n Running loads each leg at 2 to 3 times bodyweight per stride. Walking loads at around 1.2 times. If you are carrying extra weight, new to exercise, or coming back from injury, that difference matters enormously.<\/p>\n If you want to run eventually, walk 10,000 steps a day for a month first. Your joints and tendons will thank you.<\/p>\n<\/div>\n Running is excellent once the foundation is there. Signs you are ready:<\/p>\n At that point, a gentle run-walk programme slots in beautifully. Before that, you are just accumulating micro-injuries.<\/p>\n If fat loss is the goal, walk. Aim for 8,000 to 10,000 steps a day, brisk enough that you could hold a conversation but not sing. Pair it with the calorie target from our macro calculator guide<\/a> and two to three strength sessions. That is the quiet, boring, effective answer.<\/p>\nAdherence: walking wins everywhere else<\/h2>\n
