Overall, the present study provided some evidence to suggest
that the TPB model is useful in predicting the consumption of foods
low in saturated fats among adults diagnosed with Type 2 diabetes
and/or CVD with attitudes and subjective norms predicting
behavioural intentions. In addition, the study provided support
for the notion that the extent of planning people undertake serves
as an important post-volitional factor in facilitating the intake of
foods low in saturated fats, both by directly predicting behaviour
and by mediating the impact of intentions and PBC on subsequent
actions. Future research should continue to examine the utility of
the TPB and in particular the role of planning in predicting the
performance of healthy behaviours, especially in clinical samples
where the need to adhere to healthy lifestyle choices is crucial.
