Summary

The Reset trial, led by Stanford University, aims to find the best combination of four dietary strategies for weight loss in a fully digital program. 208 adults with overweight or obesity will receive a 12-week remote intervention that includes daily self-weighing, weekly lessons, and tailored feedback. Participants will be assigned to limit red zone foods, limit eating windows, increase protein, or increase fiber—or a mix. The study uses a special framework to identify which combination works best, with weight change measured at 1 and 3 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
behavioral weight loss intervention with dietary strategies (limiting red zone foods, limiting eating windows, increasing protein, increasing fiber)
What this could lead to
If successful, this could identify the best combination of simple dietary strategies for effective weight loss in a fully digital program.
What could go wrong
This is a small, early-stage optimization trial (not a test of a new drug), so results may not apply broadly. Weight loss depends on individual adherence, and the study is not designed to prove long-term effectiveness.
