This study is looking at how exercise and physical activity during and after pregnancy might change breast milk. Researchers want to see if these changes in breast milk, specifically in its fats (lipidome) and other small molecules (metabolome), could affect how babies use energy and potentially help prevent childhood obesity. You might be able to join if you are a woman between 18 and 45 years old, have a healthy pregnancy, and plan to exclusively breastfeed for at least three months. The study aims to enroll 200 participants and is actively recruiting. By understanding this process, the study hopes to improve advice for exercise during and after pregnancy to benefit infant health.
