It’s best to go grocery shopping after a meal or a snack. If you go when you are hungry, you may end up buying carbohydrate foods that give quick energy. They stock the carbs in the front of the store and in the check-out aisle to temp tired and harried shoppers.
Squeezing in time to shop between other important tasks may cause stress and, you may not be able to concentrate as well as you want to on what you want to purchase. Larger grocery chains also layout stores to ensure that you pass carbohydrate and sugary foods in between where you really want to do your shopping—in the meat, fish, egg, and dairy sections.
The bigger the store, the more confusing it may be. The profit margin for snack foods is much higher than the profit margin for steak and salmon, so there will be aisle after aisle of these. If you can, find a store with a dedicated meat and fish counter, so it will be easier to avoid the bread and cookie aisles.
When you are starting out, depending upon where you live, going to the butcher and fish market would provide you with only animal-based foods. The owners can also offer you guidance on different cuts of meat and types of fish they have available. When you go to the store, bring a list you have made at home beforehand, stick to it so, you don’t end up buying something you didn’t plan on buying.
