What is already known about this subject?
- Infants who are formula fed have an increased risk of overweight and obesity compared to breastfed infants.
- Individuals who are satiety responsive, matching their intake of energy to need, are more likely to be a healthy weight.
- Breastfeeding may promote satiety responsiveness as the infant has greater opportunity to regulate their intake of milk in comparison to being fed with a bottle. However little research has been conducted on this relationship.
