Summary

This study looks at how eating dairy yogurt or plant-based yogurt for 12 weeks affects body composition, bone density, and gut bacteria in overweight postmenopausal women. Participants will follow a weight-loss diet and be randomly assigned to eat two servings of dairy yogurt, plant-based yogurt, or no yogurt daily. The goal is to understand if dairy protein offers unique benefits for health.

What this could mean

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

Active substance
Dairy yogurt or plant-based yogurt
What this could lead to
If successful, this could clarify how dairy protein supports body composition and bone health, potentially guiding dietary recommendations.
What could go wrong
This is an early-stage observational study with only 75 participants, so results may not apply broadly. It does not test a new drug or treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.
