Why do breastfed babies get chubby?

Generally, breastfed newborns gain weight faster than formula-fed babies for the first 3 months of life. One likely reason for this is that breast milk is a dynamic and ever-changing food, composed of the exact nutrition a baby needs at that stage. On the other hand, formula is a static composition of ingredients.
