Expatriate medical insurance customers who are hoping to lose weight after piling on the pounds at Christmas should not cut out certain food types.
According to Jenny Caven, a spokeswoman for Slimming World, a strict detox is not the best way to shape up.
"The latest evidence shows that restricting yourself can be counterproductive and quickly lead you to fall off the wagon," she noted.
"The most successful way to lose weight sustainably is to swap unhealthy foods for healthier alternatives and to fill up to satisfy your appetite with basic everyday foods like plenty of fresh fruit and vegetables, pasta, potatoes, lean meat, fish, eggs and fat-free dairy products."
In addition, individuals should cut down, but not give up, alcohol, chocolate and crisps, Ms Caven suggested.
Her advice comes after research from Engage Mutual revealed that eight out of ten women are concerned about their partner's unhealthy lifestyle and its associated problems.
