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.
A 3-year-old's basal metabolic rate (BMR) varies based on factors like weight, height, and overall health, but it generally ranges from about 800 to 1,200 calories per day. BMR represents the number of calories their body needs at rest to maintain essential functions such as breathing and circulation. As children grow and develop, their BMR will change to accommodate their increasing energy needs. It's important for parents to ensure their toddlers receive a balanced diet to support healthy growth.

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.
The basal metabolic rate (BMR) for a 75-year-old male typically ranges from about 1,600 to 1,800 calories per day, depending on factors like weight, height, and overall health. BMR generally decreases with age due to loss of muscle mass and hormonal changes. To get a more accurate estimate, it's advisable to use specific BMR calculation formulas, such as the Mifflin-St Jeor equation, which takes into account individual characteristics. Regular physical activity can help maintain a higher metabolic rate even in older age.
The metabolic rate of a 2-year-old is generally higher than that of an adult on a per-kilogram basis. This is because young children require more energy relative to their body size to support rapid growth and development. In contrast, adults have a lower metabolic rate as their growth has stabilized, and their energy needs are primarily focused on maintenance and daily activities. Overall, the metabolic rate decreases with age, with children exhibiting higher rates in their early years.
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.
1 calf per year.
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.
2200- 2800 depending on their metabolic rate.
