Most adults require roughly 2000-2500 calories per day to mntn their health, but this varies based on age, ger, weight, height, and physical activity level. Overconsumption can lead to excess weight gn while a deficit might result in malnutrition.

for caloric intake are closely tied to the BMR Basal Metabolic Rate, which is influenced by factors such as sex, age, body size, and muscle mass. The Harris-Benedict equation calculates BMR using these parameters:

BMR = 655 + 9.6 x weight in kg + 19.1 x height in cm – 4.7 x age

To estimate dly caloric needs including physical activities, multiply the BMR by an activity factor:

• Sedentary lifestyle: Factor of 1.2

• Lightly active lifestyle: Factor of 1.375

• Moderately active lifestyle: Factor of 1.55

• Very active lifestyle: Factor of 1.725

It is crucial to understand that calorie requirements are not static and change over time with age, ger transitions, physical changes e.g., pregnancy, and health conditions.

For an individualized approach:

• Young adults require around 2400-3200 calories dly.

• Middle-aged individuals might need about 2200-3000 calories.

• Older adults may only need 1800-2600 calories deping on their activity level.
