If you are not lazy, maybe try to fill all the data in the formula yourself (using Harris-Benedict Formula):
1) At first calculate BMR:
For Men:
BMR: 66.5 + (13.75 x weight in kg) + (5.003 x height in cm) - (6.775 x age in years)
2) Then add your activity level: to determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:
- If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
- If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
- If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
- If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
- If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9
3) and from the result you should subtract 10%, 15%, 20% or 25% depending how fast you would like to lose the weight.
I have used this Formula now and in the past and have found out that it is the closed to the truth.
