I have done quite a bit of reading on protein intake for building muscle and I am looking for opinions on this.
I see most people in here saying 1.7-1.8g/lb, most of what I read in articles online is saying 1.7-1.8g /kg.
What gives?
Probably just a error in using the units.
This is a highly debated topic.
I weigh 140 lbs, and while dieting, I find that I do really well with 200-250 g protein, probably 60 to 80 g of that is from whey protein.
Great calculation by Chris Lockwood
Personalize Your Protein Needs
1. Choose your current training cycle from the list that follows.
2. Determine your desired (goal) body weight, in pounds.
3. Multiply your desired body weight by the suggested grams of protein per pound of body weight per day.
4. Results from Step 3 provide you with your recommended grams of protein per day.
5. Divide your total daily protein into six meals per day.
6. If Step 5 suggests you need fewer than 25 grams of protein per meal, round up to 25. In other words, everyone using this system will have at least 150 grams of protein per day.
Current training cycle:
Off-season or moderate
You have no specific goals beyond maintaining your current body composition.
You need 0.8 grams of protein per pound of body weight per day.
Moderate to high intensity
You're pushing yourself to build muscle, gain strength, and/or lose fat.
You need 1 gram of protein per pound of body weight per day.
High intensity or pre-competition
You're in serious training, possibly preparing for a bodybuilding contest or some other competition that requires peak performance.
You need 1.36 grams of protein per pound of body weight per day.
