It is no joke that when overwhelmed by choices, we tend to have less willpower. Why order a salad from a restaurant menu full of variations of lasagna? When trying to curb unhealthy eating habits or to lose weight, a fridge full of food can be a mental minefield. Here's a simple trick: only buy enough groceries to last you for two to three days instead of stocking up on tons of food. Yes, you will be heading to the supermarket with a greater frequency, but your produce and meat will be super fresh. This way your fridge will only be filled with healthy choices, making it easier to stick to your meal plan. A couple more perks to this plan — the chances of forgotten food going bad will decrease because it will be easier to eat all that you have. When buying fewer groceries you can bike to the store and just fill up a backpack, burning some calories while stocking up.
