The aim of our study is to compare adherence to the MedDiet between women who received a nutritional educational intervention during a 6-month follow-up and those who did not receive an intervention. Additionally, investigators will examine how this intervention affects mothers' nutritional status, anthropometric measures, and mental health. The objectives of this study are: 1. To assess the impact of an educational intervention on MedDiet adherence among lactating women aged 18-40 years in Jordan over a six-month follow-up period. 2. To explore the relationship between MedDiet adherence, obesity, and mental health among lactating women aged 18-40 years in Jordan during the same period.
