Parenteral	Glucose (g/kg/d)	Protein (g/kg/d)	Lipids (g/kg/d)
Conservative	6.0 (day 1)–18a	0.5 (day 1)–4.0b	0.5 (day 3)–3.5c
Aggressive	7.2 (day 1)–18a	2.0 (day 1)–4.0b	1.0 (day 1)–4.0c
Enteral	First feedings	Breast milk fortifier	Formula
Conservative	stable infant, no defined increase	at full EF	Start with diluted eHFd; preterm formula at full EF
Aggressive	first day of life, increase max. 20 ml/kg/d	at 100 ml/kg EF	Always preterm formula

Notes.

Guidelines for nutrition of ELBW infants using a conservative or aggressive approach. Using aggressive nutrition, parenteral protein and lipids were introduced earlier and EFs were started with full strength preterm formula instead of diluted eHF on the first day of life. Enteral feedings were always started with formula and switched to own mother’s breast milk as soon as available. Breast milk fortification was started earlier using the aggressive approach.

^aincreased by 1–2 g/kg/d as tolerated.

^bincreased by 0.5 g/kg/day.

^cincreased by 0.5 g/kg/day as tolerated.

^dstarted at half strength, increased stepwise to full strength at half enteral nutrition.
