You call this "data driven"? Look at his explanation of the supplements he takes:

>Grenade Thermo Detonator: A scary name, but essentially a dosage of caffeine from concentrated green tea extract that's meant to be a fat-burner/pre-workout pill. It gives you some energy to focus, and suppresses your appetite. It is not very different from simply taking a packet of coffee. I used these for the first 4 months.

>Multivitamin: Just to ensure you get your vitamin requirements for the day, but there is evidence to show this might not really be necessary.

>Fish Oil: I heard from many sources that omega-3s are good for you so I thought I'd get some

>Whey Protein: If you don't consume enough protein a day and are on a weight loss plan, you will lose muscle with your weight. 1 - 1.5g/lb of body weight is the general recommendation. Because it's not always easy to make sure you get that much pure protein, a protein shake is an easy way to quickly gulp down 50g of protein regardless of how hungry/full you are.

So of the four he takes, one he takes may not be backed by any data, and another he takes because he heard that it's good for you.

We do not really need as much protein as the supplements industry would have us believe.

The protein numbers are rather incorrect, too. Research supports 0.82g/lb (https://bayesianbodybuilding.com/the-myth-of-1glb-optimal-pr...) - though you're not going to hurt anything if you're getting more than that (unless you start taking in several multiples of that quantity - then renal failure can become a concern).

Protein tends to be more expensive on a per-calorie basis than other macronutrients, though, so it can be advantageous to not overconsume it relative to fat/carbs, presuming you're getting enough to optimally support muscle synthesis.
