This is a question that is commonly asked by people who want to lose weight. How many calories do they need to consume in order to lose weight?
Well, it all depends.
It depends on how much you weigh now, how tall you are, whether you are male or female, how old you are, and how active you are.
To determine how many calories you need to consume each day, you need to work out your Basal Metabolic Rate (or BMR). This is the number of calories you'd burn if you stayed in bed all day, which is something you hopefully don't do!
You can follow the formulas below to work it out yourself :
English BMR Formula
Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years)
Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in years )
Metric BMR Formula
Women: BMR = 655 + ( 9.6 x weight in kilos ) + ( 1.8 x height in cm ) - ( 4.7 x age in years )
Men: BMR = 66 + ( 13.7 x weight in kilos ) + ( 5 x height in cm ) - ( 6.8 x age in years )
Now, to take into consideration what level (if any) of exercise you do, to determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:
If you do little or no exercise : Calorie-Calculation = BMR x 1.2
If you do light exercise/sports 1-3 days/week : Calorie-Calculation = BMR x 1.375
If you do moderate exercise/sports 3-5 days/week : Calorie-Calculation = BMR x 1.55
If you do hard exercise/sports 6-7 days a week : Calorie-Calculation = BMR x 1.725
If you do very hard exercise/sports & physical job or 2x training : Calorie-Calculation = BMR x 1.9
Ok, so that's to work out how to maintain your current weight. There are 3500 calories to a pound, so over the course of a week you would need to reduce your calorie intake by around 500 calories a day if you want to lose weight.
There are of course "safe" and "unsafe" ways to do this. Starving yourself is NOT going to help you lose weight and keep it off, so it's important your intake is appropriate for your body type and your goals!
I am not a big fan of counting calories (but I am a "label reader")and I know it is important for everyone to know what their BMI is. It is also best to have a BMI anywhere between 19 and 24. You may need to keep track of your calories at first but once you get onto eating what is generally healthy, you will no longer need to keep track..you will just know. If you make good choices say 85% of the time and sometimes....15% of the time you don't, it will all work out in the end.
