If I were to use this nutritional approach, I would use it almost exclusively during a strength cycle AND only when I’m in caloric surplus with little life stress.
I personally would not use it for athletic performance due to energy system demands (especially when you already have lower glycogen reserves). Even with the pre/intra workout fuel, it would just not be enough for me to perform well. Maybe on the first training day of the week after I’ve refueled myself with a high carb intake (from the fruits, potatoes, etc) from the day before. But later in the week my performance would almost surely go down, not only due to lowered glycogen reserves but also because of overexcitation.
To be honest I would also crash really hard mentally after a couple of weeks, even when I’m not on a caloric deficit, simply because I would be constantly amping up my brain for 6 days in a row and then try to compensate that on 1 day.
All the motivation and drive you get from elevated dopamine actually won’t do you no good if you naturally have lower serotonin levels. You body will just convert that extra dopamine to adrenaline, which will eventually lead to desensitization of the receptors, lower serotonin and GABA levels even further, and in the end it also leads to a reduction in dopamine due to increased conversion. That’s a really bad state to be in mentally. However, this will not be the case for someone who naturally has high serotonin, acetylcholine and GABA levels. They’ll probably feel awesome using this strategy.
Genetic neurotransmitter setup IS important. That’s also why there are so many food belief systems because some people swear by high carb diets. Others swear by high protein/high fat diets. I believe it has a lot to do with how they feel mentally and that’s where nutrition and neurotransmitters come in to play.
Anyway, I digress. Would I try this for strength? Under the right conditions, yes. I would definitely not use it for athletic performance because mentally speaking that would be a bad choice for me.
