Investigating the Evolutionary Impact of Metabolic Flexibility on Physical Activity-Dependent BDNF and Cognition: Insights From the Val66Met Polymorphism

During the ketosis trial, participants will be given d-beta-hydroxybutrate mixed with sugar-free gatorade in a 1:1 ratio. This is to ensure the participant's electrolytes are high and to mask the bitter taste of d-beta-hydroxybutrate. The dosage per participant will be calculated 0.1816g/lb based on body weight to ensure participants remain in a state of ketosis for a minimum of 2 hours.

Participants will consume a placebo consisting of a pure electrolyte drink.
