Losing weight could be as simple as making a grocery list and sticking with it. That’s according to a RAND Corporation study – which found that about a third of shoppers always use a grocery list. Another third sometimes do, and the rest NEVER take a list to the store. The result: Those who planned their meals in advance and shopped from a list weighed 5 pounds less, on average… that’s compared to those who bought whatever struck their fancy. The researchers believe planning what you’re going to buy before going to the store helps you stay focused on what you came for……And better able to resist high-calorie and high-fat food and treats.
