An expert explained how it can speed up the metabolism, suppress the appetite and promote fat-burning.

She said: "Olive oil helps you lose weight because it is rich in monounsaturated fatty acids.
"These are known to help with weight loss by increasing your metabolism, reducing your appetite and reducing your body fat.
“Studies have revealed a treatment group who were given extra virgin olive oil (EVOO) lost 80 per cent more body fat than the control group who didn’t consume EVOO.
“In the long-term, olive oil continues to have positive effects on the body and keep the weight off or stable."
A study published in the National Library of Medicine found eating more monounsaturated fats is better for weight loss and maintenance than saturated fats.
As olive oil is a good source of monounsaturated fats, it could be one way to get this into the diet.
However, more research is needed into the specific benefits of taking a shot of olive oil daily.
Slimmers looking to add olive oil into their diet can do so by consuming it on its own or adding it to a meal, the expert suggested.
