OBJECTIVE: The aim of this study was to examine differences in rates of non-caloric beverage adoption by participants classified as sweet likers (SLs) or sweet dislikers (measured using a behavioural tasting task).
METHODS: Data are a sub-study from a 6-month, three-group, randomized weight loss trial (CHOICE) (body mass index 36.3 +/- 5.8 kg m-2, 84% female, aged 42.2 +/- 10.9 years, 53% African-American) comparing the replacement of caloric beverages with either non-caloric sweetened beverages (diet) or water (water) compared with a control group. This sub-study, which included participants within the water (n = 106) and diet (n = 103) groups only, examined whether SLs (n = 33 water; n = 37 diet) varied in their adherence to caloric beverage recommendations compared with sweet dislikers (n = 73 water; n = 76 diet) over the 6-month study.
RESULTS: Diet intake and sweet-liking data collected on 190 (3 months) and 169 participants (6 months) were used for analysis. The interaction between SL status and beverage group (diet vs. water) approached significance (P = 0.06) at 3 months but not 6 months. Caloric beverage intake (% energy) at 3 months was significantly higher in SLs within the water group (9.7 +/- 1.4%) compared with SLs in the diet group (5.4 +/- 1.0%, P = 0.03).
CONCLUSIONS: Results suggest that SL status may affect the rate in reduction of caloric beverages when water is the recommended substitution. Future studies should explore tailoring beverage recommendations to tasting profile.
