By Juliette Fariley NEW YORK ( MainStreet)-- Consumers are more likely to gain weight when paying with credit cards, because they are more likely to buy junk food as a result, according to a new study. Credit cards weaken the impulse control of consumers, making it more difficult for them to rationalize that something is not a necessary purchase, according to the study. "It gives a lot of people a rush to use a credit card but you become numb when using one, so I recommend a debit card instead because you get the same hit without incurring debt when the purchase amount is withdrawn from your checking account," Winston said.
The research was compiled by studying the contents of shopping baskets. "People deb,t because they're not clear on what their income is and then use credit cards to make up the difference," Winston said. "It's the same thing with food. We eat a bunch of calories, because we don't run the numbers but fast food restaurants are starting to put calories on the board now." Joining McDonald's and other restaurant chains who have been posting their calories on menus, Starbucks announced plans to post calorie information for its beverages on menu boards this summer.
