What’s one “bro science” belief you used to swear by that you’ve completely changed your mind on?

I’ve been around this game for a long time, and one thing I’ve learned is that a lot of what we all accepted as fact 10–15 years ago doesn’t always hold up when you look at more data or personal experience.
For me, a few examples are:
  • Thinking more gear always equals more growth.
  • Believing AI use should always start at a specific dose regardless of bloodwork. Assuming every plateau meant I needed another compound instead of fixing training or nutrition.
Curious what everyone else has changed their mind about over the years.
What’s one piece of advice you used to defend that you wouldn’t give someone today?
 
Gonna take some heat for this one, but that you need hundreds and hundreds of grams of protein per day to grow. I’ve done it both ways, super high and moderate intake and saw no difference between the two. I tend to fall into the Mike Mentzer camp on this one.
IMO the amount of protein is not nearly as important, as carb timing, and knowing the glycemic scale. That's what I've personally learned over the years.
 
How about in the reverse scenario of cutting though? I've always been at around about 1g/lb of bodyweight but then think that it may be better to go for lean mass. I ask because I'm currently in situation where my cals are quite low and I don't want to give more cals to protein. I'm in two minds as I think that you're less likely to lose muscle running anabolics in the first place but is 185g protein too low for someone who is around 9% at 196lbs?

Thats a great one- once I upped my carbs, I grew! Around 1-1.25g/lb works for me, little bit of added fats, and fill the rest in with carbs!

Nah. I agree with you. Yes, we need it for repair amongst other functions, but I believe carbs are more important for growth than excessive protein consumption.

One myth that I wish I could go back and change was "chicken, brown rice, and broccoli" for every meal. When I was in college, (2003-2007) this was what I ate for a large portion of my meals. 1) It tasted like shit 2) Brown rice and broccoli make me feel like shit!
It was almost like jasmine or other white rices were demonized.

And let’s not forget that you can’t eat more than 30 to 40 grams of protein per meal or it won’t be absorbed.

In a deficit you would want more protein. I would definitely increase your intake at 196lbs. You always want to have a buffer of more protein because having too little is no bueno. Also, excess protein is not the same as eating excess carbs/protein. In a surplus calorie environment in which carbs are high is the time you can ease up on protein since carbs are protein sparing.

I get what you're saying but don't the anabolics play a type of role as that buffer in that the body won't break down muscle to use as fuel? I'm just theorizing here myself, maybe to justify eating less. I don't use shakes though so one a day won't hurt to bump up the protein to around 210g. Thanks!
 
Yeah, not sure why white rice got so demonized.

This one had been going around for decades. Just the notion that once the body hits 40g of protein it's all lost. Oh man, I fell for that one like crazy.

Mine: the anabolic window. Did I ever fall for the marketing. Had to make sure I slammed protein shake of some kind like the second I was done with my workout. I still do this for preference rather than to miss out on that window.

Brother you are such a wealth of knowledge.

I think this gets overstated too. Once you’re hitting a reasonable intake (around 0.7–1.0 g per lb of lean body mass for most people), the returns seem to diminish pretty quickly. Training quality, recovery, total calories, and consistency have always made a bigger difference for me than chasing 300+ grams of protein.

I think you’re fine at 185g. At 196 lbs and ~9% BF, that’s already around 1.0 g per lb of lean mass, which is more than enough for most people—even in a cut. I’d rather use the extra calories on carbs to keep training performance up. If you’re running anabolics and training hard, preserving muscle is generally less of a concern than it is naturally. Unless you’re noticing strength dropping or recovery suffering, I wouldn’t push protein any higher.
 
The just shove anything and everything in your mouth when bulking. Eating lean Whole Foods at a slight surplus is the way to go. There’s a gentlemen at the gym I frequent whom I’ve literally heard say verbatim “ just go out and eat McDonald’s and some milkshakes” literally tells people with average builds (mind you NOT SKINNY WHATSOEVER) to just eat pure junk food. The guy is fat as fuck and can’t walk his fatass across the gym without getting gassed.

100%. White rice got unfairly demonized for years. If you digest it better and it helps you consistently hit your calories, it’s probably the better choice for you.

Anabolics definitely help preserve lean mass in a calorie deficit—they improve nitrogen retention, protein synthesis, and reduce muscle protein breakdown. But they don’t make you immune to losing muscle if calories or protein get too low. I’d still keep protein high and let the drugs be the insurance policy, not the foundation. Bumping to ~210g sounds like a solid move.

yea i feel like, not only do you put on a wicked amount of fat, but makes it harder to cut and increases cravings.
way easier to just eat more of the same or less of the same.

I think the dirty bulk mindset came from people treating calories as the only variable. Sure, you’ll grow in a surplus, but the quality of those calories still affects performance, digestion, health markers, and how much fat you gain. A small surplus with mostly whole foods gets you to the same place without spending months dieting off unnecessary fat.
