Table 3.

Snack intake by snack type, serving method, and subject sex (mean ± SEM)

Intake measure	Snack type	Women (n = 16)		Men (n = 12)
		Serving method		Serving method
		Bowl	Bag	Bowl	Bag
Weight (g)¹	Less-aerated	52.7 ± 6.9	49.2 ± 7.5	61.1 ± 6.2	70.8 ± 7.2
Weight (g)¹	More-aerated	40.1 ± 3.1	37.7 ± 2.6	52.6 ± 5.6	54.4 ± 6.6
Energy (kcal)¹	Less-aerated	301 ± 39	281 ± 43	349 ± 36	404 ± 41
Energy (kcal)¹	More-aerated	229 ± 18	215 ± 15	301 ± 32	311 ± 38
Volume (ml)²	Less-aerated	300 ± 39	279 ± 42	347 ± 35	402 ± 41
Volume (ml)²	More-aerated	501 ± 39	471 ± 32	658 ± 70	680 ± 82

For the outcomes of snack weight and energy, there was a significant main effect of snack type (energy consumed was greater for the less-aerated snack; p = 0.0003) and subject sex (energy consumed was greater for men; p = 0.034). The effect of serving method and the interactions of these factors were not significant.

For the outcome of snack volume, there was a significant main effect of snack type (volume consumed was greater for the more-aerated snack; p <0.0001) and subject sex (volume consumed was greater for men; p = 0.019). The effect of serving method and the interactions of these factors were not significant.
