There is not enought information to answet this question. The 31 year old female's weight is also needed.
If you are a normal man with average weight and height, your basal metabolic rate is about 1500 calories/day. If you are not physically active, eating more than that will make you gain weight. Eating less will make you lose weight. This is only an estimation, though. To accurately determine your basal metabolic rate and how many calories you should eat, use a calculator.

The difference in energy usage between an 18-year-old male and female is primarily due to variations in body composition, metabolism, and hormonal factors. Males typically have a higher muscle mass, which requires more energy to maintain, leading to a higher basal metabolic rate (BMR). Additionally, hormonal differences, such as higher testosterone levels in males, contribute to increased energy expenditure. These factors result in males generally needing more calories than females of the same age.
Metabolism is worked out using BMR. BMR stands for your basal metabolic rate. This is the amount of cals you burn doing nothing, just allowing your body to run. The larger you are (weight or height) the higher your BMR will be. The older you are the lower your BMR will be due to muscle loss year on year. If you have a lot of muscle compared to fat your BMR will be higher.

It depends on a lot of things, including level of activity, height, weight, and metabolic rate. 1500 Calories per day would be a healthy average, but it may be higher.

Increasing the amount of muscle you have will raise your metabolic rate. For example, if you add ten pounds of muscle in the next year through proper strength training your body will consume an additional 350 to 500 calories daily. Muscle is your metabolic furnace that burns additional calories 24 hours a day (not just during and immediately after exercise).
