Approximately how many calories should men eat per day?

• A. 1800 kcal
• B. 2000 kcal
• C. 2500 kcal
• D. 3000 kcal

Answer: (C)

Energy needs for men depend on age, body size and how active they are. For the average adult man with a moderate level of activity, about 2500 kcal per day is a typical maintenance allowance. This reflects the balance between energy used by the body at rest, plus daily activities and the digestion of food. If someone is sedentary, their needs are lower—around 2000–2300 kcal—while a very active or larger man might need 2700–3200 kcal. So, 2500 kcal sits as a common, reasonable estimate for maintaining weight in a typical man, which is why it’s the best choice. The other numbers fit narrower situations: 1800 kcal is generally too low for most adult men, 2000 kcal is a rough reference that’s often used but can be low for many, and 3000 kcal is high and suits only those with higher activity or larger size.
