Protein: Protein intake is a bit of a controversial issue in nutrition. The general recommendations given in the 'bodybuilding' area are nearly double the 'standard' recommendations given in the Sports Nutrition Arena. The GENERAL sports nutrition guideline based on clinical trials suggest that in the face of ADEQUATE calories and CARBS the following protein intakes are sufficient: STRENGTH training -> 1.4 to 2g per KG bodyweight (about .6 / pound) ENDURANCE training -> 1.2 to 1.8g per KG bodyweight (about .8 / pound) ADOLESCENT in training -> 1.8 to 2.2g per KG bodyweight (about 1g / pound) BUT researchers also acknowledge that protein becomes MORE important in the context of LOWER calorie intakes, or LOWER carb intakes. Recent evidence also suggests that protein intakes of 3g/kg help with physiological and psychological stressors associated with high volume or intense training. One should also note that ADEQUATE v's OPTIMAL is not discussed when it comes to hypertrophy v's performance. And lastly - you need to consider thermogenics/ satiety/ and personal preference.
So - General 'bodybuilding' guidelines for protein would be as follows: - Moderate bodyfat and training load = 2.2-2.8g per kg TOTAL weight (about 1-1.25g per pound) - Very Low bodyfat or Very Low Calorie or High training load = 2.4 - 3g per kg TOTAL weight (1.1-1.35g per pound) - High bodyfat, high calorie, or low training load = 1.6 to 2.2g per kg TOTAL weight (.75 - 1g per pound) Anecdotally, as most find HIGHER protein intake better for satiety, partitioning, blood sugar control, and hypertrophy. UNLESS you have medical reasons for lower protein, or unless guided to use the GENERAL sports nutrition guidelines, I would suggest the BODYBUILDING values.
