Offering a wide variety of ice cream flavors will likely lead to Janet eating more because she will want to try a little bit of each flavor. This is known as the "variety effect" in which people tend to consume more when there are more options available to them. The other options may have some effect on how much she eats, but offering a greater variety of flavors is the factor most likely to influence her consumption.
