Consumers may waste money on chocolate-scent products marketed for fitness performance based on flawed research; those relying on such products for workout gains will likely experience only placebo effects, leading to disappointment and reduced trust in fitness innovation claims.
Potential regulatory scrutiny of supplement and fitness product marketing claims; scientific journals may face pressure to strengthen peer-review standards for exercise science studies; consumer protection agencies may issue guidance on evaluating viral health claims with methodological weaknesses.
