Standing vs sitting - does it really burn calories

You have seen the ads. Buy a standing desk, stand while you work, and the kilos will melt off. It sounds smart — after all, standing feels harder than sitting, so it must burn a lot more, right? The honest answer: standing does burn more than sitting, but the difference is small. About 9 extra kilocalories per hour. Over a full desk day that is roughly 70 kcal — the energy in half a roti. A standing desk is still a fine idea for your posture, your energy, and your blood sugar. It is just not a real calorie-burn strategy. To burn more, you have to actually move.
