It’s time to put this issue to bed once and for all! And we can do it with science!
A HUGE meta-study  or “meta-analysis” (which just means a study of all the studies) has put together the results of 49 “How much Protein” studies carried out on 1863 subjects.
1.62g of protein per Kg of bodyweight seems to produce optimal levels of muscle growth. That’s comes to about 0.74g protein per pound!
If you are 200lbs, that comes to 148g.
That’s according to Robert Morton, an exercise scientist at McMaster University who carried out this meta-analysis. He also saw the following relationships when studying the data:
- A relationship between protein intake and muscle tissue i.e. the higher the protein intake, the more muscle the people had
- Protein supplementation increased 1-rep maxes and cross-sectional muscle-fiber area meaning increased gains in muscle size
NOTE: Please ensure that you are actually stimulating growth in the gym in the first place. All the protein in the world will not build any muscle if your workout is not intense enough. Use a high-intensity, growth stimulating workout like my free THT training – click here to download it.
Ok, interesting study results. But other meta-analyses have found higher recommendations – above 0.8g per pound.
And then there’s the industry-accepted recommendation of 1g per pound – which I also use and recommend.
WHY DO I RECOMMEND 1G PER POUND? 1 word…
These figures are mean averages. And there are always people who are outside the norm. You could be one of them! You might just be an “outlier”.
This means that your body might make use of 0.9g protein per pound or a whole 1g per pound. And if you don’t consume that much, you won’t be making the gains you could! It’s not worth the risk. And that brings up another word…
By taking 1g per pound, you will have something really valuable – certainty! Wouldn’t you like the certainty of knowing that your body has all the protein it needs to build muscle at a maximal rate? Again, why take any risk with this?
Go ahead with 1g/pound and relax safe in the knowledge that you’ve done all you can And please be aware that getting this level of protein is even more important when you’re on a shredding diet to get a six-pack. You’re at increased risk of losing muscle when cutting – so get that protein!
What would happen to excess protein? Good question. If you build muscle with 160g and you take in 180g per day, what happens to the other 20g (80 Calories) every day? Well, in order for it to end up as fat, it first needs to be converted to glucose (carb) and then from glucose to fat. These chemical conversions cost energy, so you’d have a lot less than 80 excess Calories by the time it becomes fat. BUT…it appears that the body doesn’t want to do this and ends up converting excess protein to glycogen and storing it in the muscle. See this study I wrote about that found that excess protein does NOT end up as stored body fat. How cool is that?
BY THE WAY…not all sources of protein are equally as good. Some have very low bio-availability i.e. your body just can’t use the protein to build muscle. Some proteins are incomplete i.e. they don’t contain all the amino acids. So I have put together a list of the 5 very best whole food protein sources for building muscle.

P.S. I know that putting together a diet for mass gains or getting shredded abs can be a pain in the butt, especially if you are new to this – that’s why I offer a service where I will do all the tough ground work for you.
You probably don’t know how many calories you need, or how many grams of protein, carbs or fat you need (based on your personal stats)…BUT I DO. Then I can take these numbers and create an exact meal plan for you to hit those numbers spot on! You’ll know what foods to eat and even when to eat them. All you have to do…is do it. No thinking involved. If you’d like me to take care of this for you, see the Get Me Shredded option on my Coaching Page here.
Shoulder Blast Workout
In Jan 2019 a bunch of 'lab rats' tested the New Shoulder Blast Workout and gained up to 2.5 inches in shoulder size in 7-10 days! There is a very specific type of training stress that works uniquely well for the shoulders. You're about to target it...hard! More details here.
