If you’re sticking to your diet, you might not be sticking to your budget. A study in the March issue of the Journal of Consumer Research indicates that people who have exercised self-control in some other area are more prone to make impulse purchases.

People need self-regulatory control to avoid impulse buying but if their resources of self-control are depleted by something else, like a new exercise or diet program, they are less likely to be able to muster the sales resistance necessary.

So, if your husband wants to know why you bought so much at the mall, just tell him “I’m dieting”.

On a diet? You’ll spend more on impulse purchases
