The standard 2000 a day for women, 2500 for men is so vague and generalised. It doesn’t account for activity level, age, muscle mass. (It also doesn’t consider the food you’re eating as not all calories are equal. But that’s a whole separate point!)
But to get a clearer idea for you, try working out your BMR. This is your Basal Metabolic Rate and it is how many calories your body requires just to function. (The brain needs 600 calories a day alone!)
The metric formula for men is:
66.47 + ( 13.75 × weight in kg ) + ( 5.003 × height in cm ) − ( 6.755 × age in years )
And the metric formula for women is:
BMR = 655.1 + ( 9.563 × weight in kg ) + ( 1.85 × height in cm ) − ( 4.676 × age in years )
Then consider how active you are. Be realistic. Walking your 10,000 steps without breaking a sweat won’t increase your calorie burn drastically; going to the gym but then having a sedentary office job doesn’t equate a very active lifestyle. But even stuff like fidgeting can add to your daily energy expenditure!!! Building muscle means your calorie burn is higher as muscles require extra calories to sustain themselves. Even eating hard to digest foods like meat and raw food helps it to all add up (this is what I was referring to earlier - unprocessed natural food genuinely does mean you gain less weight than easy to digest processed food that the body doesn’t really have much use for).
So now you’re into BMR *PLUS* what you additionally burn off.
Remember it’s all an equation. Happy with your weight? Keep your calorie intake level with your energy expenditure. Want to gain? Up your calories to supersede your expenditure. Weight loss the goal? Move more, take in less calories.
It might not always be the equation you want at the end of each day, but as long as it levels out over a few days, your journey is on track 💪
