Yes and no. If you’re looking at it purely from a financial perspective, then you’ll likely get a lower cost per serving if you meal prep yourself—especially if you plan out your shopping days and buy things when they’re on sale. However, this takes a lot of extra time. You have to plan your meals, write out your grocery list, go shopping, cook, and then clean up. So from a time perspective, it may be better to use a meal delivery service over meal prepping yourself.
