“…Diets rich in n-3 fatty acids have been shown to prevent obesity better than other subclasses of PUFA (56,116) . This effect has been reported in studies in human subjects (57,138,139) , mice (48,60) and rats (62,63,65,66,102) . In most of the animal studies lower fat deposition in subjects fed n-3 fatty acids was shown despite comparable food and energy intake among the groups (48,60,62,65,66) ( Table 1; lines 12, 33, 23, 22 and 14, respectively); therefore this effect can be related to the metabolic effects of n-3 fats.…”
