You've been working your hardest, you've barely touched any 'bad' food in weeks and you've been moving around a whole lot more to help burn the calories, yet the thought of trying on a bikini still makes you shudder.
A new study, which was reported by The Today Show, has proven that trying on a swimsuit can darken a women's mood.
The research, which was conducted by psychologists at Flinders University in South Australia, found that even thinking about trying on a swimsuit increases a woman's self-objectification - where they review themselves from an outside perspective.
It is more likely to dampen a mood than the act of actually wearing a new swimming costume.
Markia Tiggemann, one of the study's researchers, explained the findings:
"We wear an choose clothes everyday clothes are controllable aspects of our appearance, in a way that body size and shape are not."
She also offered some advice to women on the hunt for some new beachwear this summer: "Avoid mirrors and comparisons with others."
