Here we go,
1st step: Your body weight in pounds divided by 2.2 = weight in Kg
2nd step: Weight in kg x 0.8 to 1.8 gm/Kg = protein in gm
Take values between 0.8 to 1.8 gm to calculate your protein needs because according to scientific research, an average person living a normal life and not performing hard works and workout needs 1 gm protein per kilogram body weight and a person who is working hard at gym must take 0.8 to 1.8 gm/Kg to fulfill his protein needs.
Example: A man who weighs 176 lbs and is a regular exerciser and lift heavy weights needs:
176 lbs/2.2 = 80 Kg
80 Kg x 1.5 = 120 gm protein/day
So, must calculate your protein needs right now. Good luck.
I will tell you about the good sources of natural protein in the next post. Stay tuned.
