A non-therapeutic method for promoting a postnatal growth trajectory or body development in an infant towards a growth trajectory or body development which is similar to the growth trajectory or body development observed in human milk fed infants comprising administering a nutritional composition selected from an infant formula and a follow on formula comprising 3 to 7 g lipid/100 kcal, 1.25 to 5 g protein/100 kcal and 6 to 18 g digestible carbohydrate/100 kcal and wherein the lipid comprises i) 30 to 90 wt.% vegetable fat based on total lipid, and ii) 10 to 70 wt.% based on total lipid of mammalian milk lipid derived from the group consisting of butter, butter fat, butter oil, and anhydrous milk fat, and wherein the lipid comprises 5 to 35 wt.% poly-unsaturated fatty acids (PUFA), based on total fatty acids, comprising linoleic acid and alpha-linolenic acid in a weight ratio of 2 to 20, and wherein the nutritional composition comprises lipid globules that have a mode diameter, based on volume, as determined by the method described in Michalski et al, 2001, Lait 81: 787-796, of at least 1.0 μm and/or a diameter of 2 to 12 μm in an amount of at least 45 volume % based on total lipid, and wherein the nutritional composition comprises at least 0.5 wt.% phospholipids based on total lipid, wherein the growth trajectory or body development is the growth trajectory or body development of the first 12 months of life of the infant, and either - wherein the growth trajectory or body development is selected from the group consisting of the trajectory or development for body weight, weight for length and/or body mass index, or - wherein the growth trajectory or body development is the trajectory or development for head circumference, or - wherein the growth trajectory or body development is the trajectory or development for skinfold thickness, preferably subscapular skinfold thickness and/or triceps skinfold thickness. i) 30 to 90 wt.% vegetable fat based on total lipid, and ii) 10 to 70 wt.% based on total lipid of mammalian milk lipid derived from the group consisting of butter, butter fat, butter oil, and anhydrous milk fat, and wherein the lipid comprises 5 to 35 wt.% poly-unsaturated fatty acids (PUFA), based on total fatty acids, comprising linoleic acid and alpha-linolenic acid in a weight ratio of 2 to 20, and wherein the nutritional composition comprises lipid globules that have a mode diameter, based on volume, as determined by the method described in Michalski et al, 2001, Lait 81: 787-796, of at least 1.0 μm and/or a diameter of 2 to 12 μm in an amount of at least 45 volume % based on total lipid, and wherein the nutritional composition comprises at least 0.5 wt.% phospholipids based on total lipid, wherein the growth trajectory or body development is the growth trajectory or body development of the first 12 months of life of the infant, and either - wherein the growth trajectory or body development is selected from the group consisting of the trajectory or development for body weight, weight for length and/or body mass index, or - wherein the growth trajectory or body development is the trajectory or development for head circumference, or - wherein the growth trajectory or body development is the trajectory or development for skinfold thickness, preferably subscapular skinfold thickness and/or triceps skinfold thickness. - wherein the growth trajectory or body development is selected from the group consisting of the trajectory or development for body weight, weight for length and/or body mass index, or - wherein the growth trajectory or body development is the trajectory or development for head circumference, or - wherein the growth trajectory or body development is the trajectory or development for skinfold thickness, preferably subscapular skinfold thickness and/or triceps skinfold thickness.
