For weight watchers, experts are experimenting with a new way to keep tabs on what you eat by what you spend on food. The scheme uses your grocery shopping bills to deliver a message about the fat content of what you have just bought.
The project, funded by the Medical Research Council, uses supermarket receipts. With them, head researcher Joan Ramsey says "it is possible to calculate precisely the diet of the family."
One British supermarket chain, Tesco, is working on a way to take the idea a step further by printing the percentage of fat and number of calories in each order at the bottom of the bill. "Till receipts have been shown to be a very useful tool for helping people measure their diet," a Tesco spokesman says.
Ramsey says health care professionals also can use the receipts to give advice on weight control and healthy eating. She suggests that anyone seeking dietary counseling could "bring along their shopping till receipts" for a counselor to point out possible changes.
