Intermittent fasting. And other trends that overlap with food and nutrition.
Biohacking is an evolving field. And so its intersections with eating, fasting, etc are open to reinterpretation.
Given how biohacking, intermittent fasting, special diets, etc are an expanding and evolving trend, foods and beverages producers can optimize their offerings for specific audiences.
I would suggest targeting the intermittent fasting group. For instance, by optimizing the nutrition they consume during their "eating window" and perhaps also the beverages they consume outside their eating window.
