Trending mis/disinformation: “idk if I’m late to this, but I am OBSESSED!”

This trending TikTok video is not backed by the evidence and promotes misinformation.

Cycle Syncing and “Optimizing your Health”

Summary
This video promotes the “28” app, which encourages cycle syncing by aligning workouts, nutrition, and lifestyle habits with menstrual cycle phases, presenting the approach as science-based and beneficial for energy and overall well-being. While the creator frames her experience as personal, she references “the science” behind eating and exercising in certain ways to affect hormones, implicitly generalizing the app’s claims. However, there is limited to no robust scientific evidence that cycle syncing significantly improves exercise performance, weight management, or overall health outcomes for most people, making the video’s framing potentially misleading.
