Here is the formula given to find out how much you need to eat to live.
If you go below this number, you enter into starvation mode.
Calculate your BMR to lose weight fast and safe:
BMR stands for basal metabolic rate. It means the amount of calories you spend to run your body systems if you stayed in bed all day.
Men: 66 + (13.7 x Weight in Kg) + (5 x height in cm) – (6.8 x age in years)
Women: 665 + (9.6 x wt in Kg) + (1.8 x ht in cm) – (4.7 x age in years)
Multiply your height in inches by 2.54 to get centimeters
Divide your weight in pounds by 2.2 to get Kg
Woman of 40 years, 5 feet 6 inches (167.64 cm), 168 pounds (76.36 Kg)
665 + (9.6 x 76.36) + (1.8 x 167.64) – (4.7 x 40)
665 + 733.56 + 301.752 – 188 = 1512.312 calories just to stay alive.
Now we add in your activity level. Take your BMR number and multiply it by one of the following numbers:
If you are:
Sedentary (little or no exercise) BMR x 1.2
Light activity (exercise 1-3 days per week) BMR x 1.375
Moderate activity (3-5 days per week) BMR x 1.55
High activity (Daily, high intensity) BMR x 1.725
Let’s continue with our previous example:
BMR = 1512.312
Sedentary = 1.2

High Activity: BMR x 1.725
2608.7382 calories to maintain weight
