Weight Loss Goal

Diet & Exercise Prescription
In order to lower my weigth, I have aim for 0.5- 0.9 kg weight loss per week. This may be quite challenging task for me...Last few weeks, one of my friend who is a direct saller selling a product name Reductil. So, she help me to plan the way to reduce weight in healty way. Frist, she help me to count my basal metanolic rate(BMR), my energy expenditure required (EE) per day and come out with one my dietary prescription.
Here aer the way to count my BMR, EE and dietary prescription:

BMR(men)= 66 + (13.7x Wt) + (5 x Ht) - (6.8x Age)
=66+ (13.7x 76) + (5x 1.7) - (6.8x 23)
=836

EE= BMR x activity factor
*Activity factor= 1.2 for sedentary
*Activity factor= 1.4 for sedentary

My EE= 836x 1.2
= 1003.2

1kg body fat = 7700kcal
so, if I want to reduce 0.5 kg weight in one week, I need to reduce 550kcal per day
If I play badminton,, I can reduce 143kcal per day.
So, my dietary = 1003.2 - (550-143)
= 1003.2m- 40.7
= 596.2 kcal
Finally, my dietary prescription was 596.2 kcal per day.
I must tell myself, I need to control my diet and go for badminton at least 4 time a week....but, I got so much time to do so???haiz....
