A new study has found that an ingredient in red wine can help with weight loss. 

Researchers discovered that resveratrol, which can be found in high concentrations of grapes, berries and red wine, can assist with the weight loss process.

The study, which was published in the International Journal of Obesity, recorded the results of mice digesting the chemical resveratrol.

The mice gained 40 percent less weight than their counterparts, which weren't given resveratrol. 

The study's lead researcher, Washington State University Professor Min Du, advised people to focus on eating blueberries, strawberries, raspberries, grapes and apples, because they all contain resveratrol.

Du noted red wine can also have the same effects as the fruits when consumed in moderation.

However, Du advised people not to rely on red wine for the ingredient, because many of the beneficial components "are insoluble and get filtered out during the wine production process."
