Standing burns how many more calories per hour than sitting?

• A. 20
• B. 50
• C. 75
• D. 100

Answer: (B)

Standing uses more muscle activity to stay upright, so it raises energy expenditure a bit compared with sitting. For an average adult, the extra effort translates to about 50 calories burned per hour when standing vs. sitting. So the best answer is that standing burns roughly 50 more calories per hour than sitting. The exact amount can vary with weight and metabolism, but 50 calories per hour is the standard estimate used in this context.
