Body weight and body composition development during WSD challenge (week 6–14) of mice that had previously been exposed to experimental diets.

(A) body weight, (B) lean mass, (C) fat mass and (D) relative fat mass of adult mice on Western-style diet (weeks 6–14) that were previously exposed (postnatal day 16–42) to experimental diet with added phospholipid ingredient (ING2, n = 12) or experimental diet with adapted supramolecular lipid structure (STR2, n = 12). A group of mice that were raised on a neutral diet and exposed to low fat AIN-93-M were monitored and included as a reference for body weight and body composition development under non-challenged conditions (REF2, n = 12). ING2, group receiving diet with altered ingredient (Study 2, milk fat globule membrane); STR2, group receiving diet with altered structure; REF2, reference diet; P, postnatal day. Data are means ± SEM; *significant difference between ING and STR group (p < 0.05).
