Ideas a builder, maker or community group could start on:

  1. A meta-analysis aggregator tool that visualizes existing clinical trial data on body composition changes during caloric restriction.
  2. A predictive calculator app that uses user body fat percentage and deficit size to estimate lean mass retention based on current scientific literature.
  3. A community-driven data collection platform where users track their body composition changes and deficit levels to build a crowdsourced dataset.

“I haven't been able to find much empirical information. This seems strange to me, since this pretty relevant for body builders doing a cut.”
