Yes, babies are generally born with a relatively high percentage of body fat. At birth, human infants have the highest percentage of body fat of any species. This "pudginess" offers an evolutionary advantage.
Why are Babies Chubby?
Babies are born with a higher fat percentage than any other species for an evolutionary advantage. This fat serves several crucial functions:
- Energy Reserve: Babies have a limited ability to regulate their body temperature and haven't developed shivering. Fat keeps babies warm in the first few months of life.
- Brain Development: A significant portion of a baby's fat intake goes directly to brain development, vital in their first year.
- Protection: Layers of fat provide cushioning, protecting internal organs from potential injury.
- Survival Buffer: The fat reserve acts as a buffer, giving them the needed energy if there are delays in establishing breastfeeding or formula feeding.
