Want a Flexible Brain? Exercise, Eat Well, and Sleep Tight!

This review summarizes the effects of exercise, diet, and sleep on the brain's ability to change (neuroplasticity), drawing largely from animal studies. While suggesting that a healthy lifestyle combining all three factors is best, it lacks enough human research to define the optimal balance or determine synergistic effects of combining different approaches. More research is needed to translate these findings into practical recommendations for people.

Possible Conflicts of Interest

None identified

Identified Weaknesses

Differences in methodologies

The findings mentioned in the review are collected from various research settings, models and studies with a mixture of different protocols and methodologies in exercise and dietary interventions. This leads to difficulties in understanding if there were any synergistic effects between combining exercise types or if a specific type of exercise was best for inducing neuroplasticity.

Exclusion of other exercise types

The review primarily focused on common types of exercise such as aerobic and resistance training, with no mention of flexibility or balance training. Other methods of inducing neuroplasticity, aside from exercise, were also not mentioned.

Limited human research

There weren't enough human studies on several topics in the review, such as sleep staging or sleep quality and quantity in relation to neuroplasticity and dietary interventions. Most evidence was based on animal studies that claimed human relevance without proper justification. Due to the small number of human studies, it's difficult to expand these findings into general applications.

Interaction not addressed

The review failed to address how different combinations of sleep quality/quantity, diet, and exercise affect how easily the brain changes in response to training or learning.

Rating Explanation

This review provides a decent overview of how lifestyle factors affect brain plasticity. However, it relies heavily on animal studies and lacks sufficient human research to support strong conclusions about ideal combinations of exercise, diet, and sleep for maximizing neuroplasticity. The differences in methodologies, limited scope of exercise types considered, and exclusion of other methods for inducing neuroplasticity weaken the review's overall impact and generalizability.
