You'll want both of your brain halves to be performing well. But you want to be especially more attentive to right hemisphere issues as that can impact your whole body, your performance and overall quality of life more than that of a left brain deficit (outside of culturally imposed restrictions).
A lot of popular social media accounts with desirable physiques are showing clear signs of dealing with body dysmorphia which is a right brain deficit. Sometimes they'll even be diagnosed with clearly left brain dominant neurodevelopmental delays such as ADHD, autism, BPD, etc. These people have strong left brains driving them to be obsessed with their tracking, training and being perfect in their specific niche. Which means what they're doing will not actually be applicable for most people.
Most people will need low effort things that will give them a high ROI on their training. Same with their diets. They'll need room to be eating out 1-2x a week, maybe even drinking 1-4x a month.
Fitness for the average person is a hard sell, but when you approach it from a brain based and pro-metabolic perspective, it can actually be fun and enjoyable.
