The RDA
1.76 g/kg/d would work. It falls within most of the reputable research.
Lemon does some good research.
Protein Timing and Dosage
What has changed is that what most important is the Protein Timing an Dosage.
Think of it this way. If you prescribed a medication dosage of let's say three 30 mg a day of something a day.
Would it matter if you took all as once or one every hour or two hours.
The same essentially applies to Protein Intake.
Research by Dr. Layne Norton, Donald Layman and Gabe Wilson clear demonstrate that, "Timing and Dosage" are everything.
Cutting Weight
Yes, when cutting weight increasing protein intake ensure more muscle mass is kept.
TEF
Yes, to some degree it will increase the thermogenic effect.
Calories In, Calories Out
However, for weight loss, calorie intake continue to be the key.
Physicians
Most are arrogant. With nutrition the majority are ignorant. It's the same with Pharmacology Medications, Physical Therapy, Exercise Physiology, etc.
They are the "Candy Men" when it come to stations. They prescribe them to individual who often don't need.
Physicians may listen to you but they Are NOT Hearing YOU.
