Interindividual variability in appetitive sensations and relationships between appetitive sensations and energy intake
Authors' conclusion
This study found that acute and chronic sensations of hunger, fullness and thirst are relatively stable within individuals but vary markedly between individuals. In addition, the present data indicate AS are poorly associated with dietary patterns or with EI under conditions of relatively stable energy balance.

Main finding
As reported in the abstract
Stability of inter-individual appetitive ratings (correlation between weeks) · weeks 1, 9, 17
- Hunger, week 1 vs week 9
- r = 0.72 (p < 0.001)
- Hunger, week 1 vs week 17
- r = 0.67 (p < 0.001)
- Hunger, week 9 vs week 17
- r = 0.77 (p < 0.001)
- Fullness, week 1 vs week 9
- r = 0.74 (p < 0.001)
- Fullness, week 1 vs week 17
- r = 0.71 (p < 0.001)
- Fullness, week 9 vs week 17
- r = 0.81 (p < 0.001)
- Thirst, week 1 vs week 9
- r = 0.82 (p < 0.001)
- Thirst, week 1 vs week 17
- r = 0.81 (p < 0.001)
- Thirst, week 9 vs week 17
- r = 0.88 (p < 0.001)
Observational data: associations, not effects.
Further findings
Relationships between appetitive sensations (AS), eating pattern and energy intake (EI)
- Cross-correlation: EI and eating pattern exerted stronger effects on AS than the reverse; absolute effect sizes small
- Path analyses: weak relationships between AS and EI
Associations with individual characteristics (age, gender, BMI)
- No robust effects of the studied individual characteristics
