That 1 gram per lb is for lean body mass. Measure your body fat %. I have a body fat analyzer by Omron that tells me I have about 17% body fat. My weight is 224 lbs.
224 lbs x 17% fat = 38 lbs (fat)
224 lbs - 38 lbs fat = 186 lbs
So I have 186 lbs of lean body mass.
Follow my method for your weight and % body fat and get your lean body mass.
As a crude rule of thumb you need 1 gram of protein per lb of lean body mass to maintain your muscle mass. If you want to increase your muscle mass the crude rule of thumb is to increase the protein to 1.5 grams per lb of lean body mass. (These are crude numbers because it also depends on your carbohydrate and fat intake and how much energy you burn up doing cardio and weightlifting.)[/quote]
Actually, protein should be increased when dieting. If you are trying to gain, hopefully you aren’t excluding all carbs and fats so your body should be using less protein as a source of fuel. When dieting, your muscles are at risk of being used as fuel in a calorie deficient diet. That is why protein is usually increased during these times. It is also why most bodybuilders base this number on BODY WEIGHT, and not just lean body mass.
