interaction between the two experimental factors [F(1,45) = 7.29;
p = 0.010]. In the ad libitum conditions, salad intake was 23% greater
when it was served before the main course (71 ± 3 kcal
[298 ± 13 kJ]) rather than with the main course (58 ± 4 kcal
[241 ± 15 kJ]; p = 0.0005). Both ad libitum intakes of salad, however,
were less than the compulsory salad intakes (100 kcal
[418 kJ]). When the salad and pasta were served together, 48% of
participants ate the ad libitum salad first (before starting the pasta)
and 63% of participants ate the compulsory salad first. This difference
did not reach statistical significance (McNemar’s test statistic
= 2.88; p = 0.09) and did not significantly affect energy intake
at these two meals [F(1,16) = 1.25; p = 0.28].
