Which of the following grocery-shopping approaches best applies behavioral strategies to reduce impulse purchases and support long-term maintenance?

• A. Shopping with a planned list after eating a full meal, avoiding aisles with highly processed snack foods, and using the list to limit unplanned purchases.
• B. Shopping every day when slightly hungry so that you buy fresh items you will definitely eat, and relying on impulse choices to keep the diet varied and interesting.
• C. Shopping only online and ordering all items in bulk without a list so that you can take advantage of promotional offers that increase variety but not necessarily nutritional quality.
• D. Shopping with a rotating set of pre-selected favorite meals and deliberately leaving the produce section unattended to minimize decision fatigue and over-selection of vegetables.
