Women with a sweet tooth are ‘more in tune with their bodies’ and better able to tell when they feel full, study finds
- New study suggests sweet fans can better detect the internal state of their body
- Sweet lovers were also ‘more mindful and intuitive eaters’ than ‘sweet dislikers’
- The study may help create new nutrition strategies to help people lose weight
Women who like sweets are more in tune with their bodies and better able to tell when they feel full, a new study suggests.
Psychologists from the University of Sussex performed a series of tests on 64 women, who were either ‘sweet likers’ or ‘sweet dislikers’.
The team found the sweet likers had enhanced ‘interoceptive’ abilities – in other words, they better perceived the internal state of their body – and were the ‘more mindful and intuitive eaters’.
The study goes against a stereotype that people who love sweet foods like candy, chocolate and cake can’t stop eating them even when they’re full.

Do you have a sweet tooth? The study suggests you can better detect the internal state of your body – including whether or not you’re full
‘This study is interesting because it runs contrary to what many people might think,’ said Dr Vasiliki Iatridi, lead author on the paper, at the University of Sussex.
‘If you’re partial to very sugary food, it doesn’t mean that you’re at the whim of your cravings.
‘It might mean the opposite – that you’re less likely to cave in to the call of the candy jar in the absence of hunger.’
The 64 participants in the study were categorised as sweet likers or sweet dislikers after being asked to taste and rate sugar solutions of varying intensities.
Firstly, to determine their cardiac interoception, participants were first fitted with heartbeat trackers.
Sweet-likers were found to be better able to sense their own heartbeats, without actually measuring their own pulses, than sweet dislikers, the team found.
After this, participants conducted the two-step water load test – involving the ingestion of non-caloric water.
During the first step, water ingestion was required until the point of perceived satiation, which was ‘the comfortable sensation you perceive when you have eaten a meal and you have eaten enough, but not too much’.
Participants were then asked to continue ingesting water until fullness – the ‘sensation of stomach being entirely filled with water’ – was reached.
Gastric interoception was defined as the volume needed for satiation expressed as a percentage of total stomach capacity.
Researchers found that sweet-likers were more able to tell when they were full – in other words, they had better gastric interoceptive abilities.
Sweet likers also scored higher on mindful and intuitive eating scales, meaning they were less likely to be affected by edible temptations.
‘Our study shows that people who like sweet foods are able to detect the physical sensations which signal when they’re full up,’ said study author Professor Martin Yeomans at University of Sussex.
‘Surprisingly it is those who don’t like sweet tastes who may be less able to self-regulate their eating.
‘What we still don’t know is what makes someone a sweet-liker or disliker, and that is what we are now looking into.’
Researchers believe their paper could open up new personalised nutrition strategies in helping people lose weight.
‘Measurement of individual variation in sweet-liking may prove useful to identify those predisposed to poorer interoceptive abilities and, hence, to food choices beyond internal needs and ultimately unhealthy body weights,’ they say.
This study, published in the journal Appetite, only looked at female participants but it is hoped that further studies include men.
