If you struggle to get excited by a plate of salad, you might want to try staring at a picture of pizza as you eat.
That's because scientists at the Nestle Research Centre in Switzerland have found that people who looked at pictures of high-carb food like pizza or pastry say that their food tastes better than those who look at images of healthy foods like watermelon or grapes.
The Daily Mail reports that this happens because vision plays a major role in our perception of food - and if something looks good we're more like to enjoy it and think that it tastes good.
In a study, 14 volunteers were shown quick images of either high-carb or low-carb food.
They were then given an electric taste test, which is a pulse which stimulates the tongue but has a neutral flavour, before being asked to rate the taste on pleasantness and intensity.
They found that those who had seen the high-carb pictures enjoyed the taste more than those who had seen the low-carb images.
Dr Johannes le Coutre, who led the research, said: "The results provide evidence that high calorie food cues enhance the hedonistic evaluation of subsequently presented tastes.
"The study provides novel insights into cross-modal sensory interactions underlying taste and probably food evaluation and consumption."
Researchers also studied brain images taken during the experiment and now believe that the study could, in future, help to treat appetite disorders.

Click on the image below to find out which foods could boost your sex life...
- Almonds<p> Almonds are rich in zinc, which is known to help increase libido and aid with fertility. You may want to give them a whiff too - the scent is purported to arouse women.</p>
- Avocados<p> The Aztecs referred to avocados as "testicle trees" because of their shape and how they grew in pairs. But it's the heart-healthy unsaturated fats they're packed with that will ensure your bedroom antics can go on all day... and night.</p>
- Dark chocolate<p> You might want to invest in some chocolate body sauce: researchers found that a compound in dark chocolate, phenylethylamine, releases the same endorphins as those produced by sex and increases sexual attraction. Sounds sweet.</p>
- Blueberries<p> Blueberries are packed with fibre, which helps keep cholesterol levels low, and are also known for improving circulation, which will help stimulate blood flow to the genitals.</p>
- Eggs<p> How about breakfast in bed? Eggs are high in B vitamins which help regulate hormone levels, and they also contain the amino acids essential for optimum sexual health. </p>
- Granola<p> Yet another reason not to miss breakfast: Foods like granola and oatmeal are high in L-Arginine, which studies have found improves sexual function in men since it helps stimulate blood flow and improve circulation.</p>
- Strawberries<p> High in zinc and antioxidants, strawberries are also a healthy way to get your energy levels up for a marathon session in the sack. Plus, we all know <a href="http://lifestyle.aol.co.uk/2012/02/09/simple-seduction-tips/" target="_blank">red is the colour of seduction</a>. Whipped cream optional.</p>

- Peaches<p> Peaches are a good source of Vitamin C, which helps boost sperm count and ensures a better quality of sperm. Frozen peaches have a higher concentration of the vitamin than fresh ones.</p>
- Oysters<p> Oysters have a reputation for getting people in the mood for love for a reason. Their high zinc content helps with arousal, testosterone production and improved circulation.</p>
- Spinach<p> Spinach and other green leafy vegetables have folate, which helps keep arteries unclogged and is beneficial for reproductive health. Spinach is also a good source of magnesium, which helps with better blood flow.</p>
- Steak<p> If you think there's nothing sexier than a big slab of red meat, you're in luck: Steak lowers prolactin levels, a hormone which may interfere with arousal, and the protein from the meat will trigger feel-good dopamine in the brain.</p>
