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.
