Calorie needs at age 67, male
Use the form to estimate your maintenance calories. For the sums, read the worked example for a man aged 67 at 5 ft 10 in and 178 lb.
How it works
Daily calories equal resting calories times an activity factor. Resting calories come from Mifflin-St Jeor: 10 times kilograms plus 6.25 times centimeters minus 5 times age, with 5 added for males or 161 taken off for females. The factor runs from 1.2 to 1.9. For a man aged 67 at the lightly active level the fixed adjustment is plus 5.
Worked example
Take a man aged 67 who is 5 ft 10 in tall and weighs 178 lb. In metric that is 177.8 cm and 80.74 kg. Multiply weight by 10: 10 × 80.74 = 807.4. Multiply height by 6.25: 6.25 × 177.8 = 1111.25. Subtract 5 × 67 = 335. Add 5. That gives 1588.65, which rounds to 1589 calories at rest. Multiply 1588.65 by 1.375 for the lightly active level to get 2184.4, which rounds to 2184 calories a day.
Maintenance calories at every activity level for the same man aged 67 at 5 ft 10 in and 178 lb, with the lightly active level set in the form above.
- Sedentary (little or no exercise)
- 1906 calories a day
- Lightly active (light exercise 1 to 3 days a week)
- 2184 calories a day
- Moderately active (moderate exercise 3 to 5 days a week)
- 2462 calories a day
- Very active (hard exercise 6 to 7 days a week)
- 2740 calories a day
- Extra active (very hard exercise and a physical job)
- 3018 calories a day
Common questions
Which activity level should I pick?
Pick the one that matches a typical week, not your best week. If you sit most of the day and train a few times, lightly or moderately active is usually closer than very active. Across the five levels this 67-year-old man ranges from 1906 to 3018 calories a day, and the lightly active level gives 2184.
How big a calorie deficit is reasonable for weight loss?
A deficit of 500 calories a day is a common starting point and works out to roughly half a kilogram a week. Smaller deficits are slower and easier to keep up. A 500 calorie deficit here means 1684 calories a day for this 67-year-old man at the lightly active level.
How big a surplus helps build muscle?
A modest surplus of about 250 calories a day is a common starting point. Larger surpluses tend to add more fat without adding muscle faster. A 250 calorie surplus here means 2434 calories a day for this 67-year-old man at the lightly active level.
Why does age 67 change the result?
The formula takes 5 calories off for every year of age, which reflects that resting burn tends to fall over time. At 67 that is 335 calories. Without the age term this 67-year-old man would burn 1924 calories at rest, or 2645 a day at the lightly active level.
How accurate is a calorie estimate?
It is a starting estimate. Track your weight over two or three weeks and adjust the target up or down based on what actually happens. For this 67-year-old man, a 5 percent error on 2184 calories is 109 calories a day.
