what is diet? why is it done?
How to determine the daily calorie needs of women, To determine the daily calorie needs of women, several factors need to be considered, including age, height, weight, activity level, and overall health. Here are the steps to calculate daily calorie needs;
Calculate Basal Metabolic Rate (BMR): BMR is the number of calories needed to maintain basic body functions at rest. You can use the Harris-Benedict equation to calculate BMR based on age, height, weight, and sex.
Multiply BMR by activity level: The level of physical activity affects the daily calorie needs. Multiply the BMR by the appropriate activity level factor to get the total daily energy expenditure (TDEE).
Adjust for weight goals: If weight loss or gain is desired, adjust the TDEE accordingly. To lose weight, reduce the TDEE by 500-1000 calories per day. To gain weight, increase the TDEE by 250-500 calories per day.
Here is an example calculation using the Harris-Benedict equation for a sedentary 30-year-old woman who weighs 68 kg and is 165 cm tall:
BMR = 655 + (9.6 x 68) + (1.8 x 165) – (4.7 x 30) = 1,433 calories per day
TDEE = BMR x 1.2 (sedentary activity level) = 1,720 calories per day
Keep in mind that these are just estimates, and individual needs may vary based on genetics, health conditions, and other factors. Consulting a registered dietitian can help determine more personalized calorie needs.
