The deal will give a presence on the 's health and fitness channels, an area of the site that receives 1.5m page impressions a month.
The five-figure deal will see eDiets given an editorial presence, as well as advertising on Handbag.com.
EDiets is the UK home of the Atkins Diet online, as well as the new GI Diet or glycemic index. Users enter their height, weight and dietary requirements and are given a personalised diet programme to suit their needs.
Alicen Stenner, brand director of Handbag.com, said: "Advice on diets has never been more important than it is today. In fact, 48% of our readers say they will be going on some sort of diet in the coming year.
"Our readers are always interested in accessing up-to-date information and the Tesco eDiets information will provide a valuable resource to them."
Tesco acquired the UK and Ireland licence for eDiets in July 2004.
