Whether you’re a newbie to the paleo diet or a dedicated devotee, it can be challenging to follow the eating plan’s rigid rules. Not only are you advised to steer clear of all processed foods, dairy, added sugars, and grains — all with the aim of eating like our caveman ancestors — but ideally, you should be eating organic produce, grass-fed, free-range meats, and sustainably raised seafood. That’s where paleo diet meal delivery services come in. They take the guesswork out of it, do the grocery shopping detective work for you, and answer the age-old question of “What’s for dinner?”

Factors to Consider When Choosing a Paleo Diet Meal Delivery Service

Pre-Made Meals vs. Meal Kits Some delivery services send ready-to-eat meals that you simply have to warm up, while others send ingredients and recipe cards for meals you have to prepare yourself. Those who don’t want to cook and clean up will appreciate pre-made meals, while those who enjoy cooking and want the freshest food possible may want to consider a meal kit.Subscriptions Most meal delivery services require you to sign up for a subscription. While all the services listed here are easy to pause and cancel, you do have to remember to do so.Cost While these delivery services are undoubtedly convenient, they can be expensive, especially when shipping charges are figured in.Packaging Meal deliveries are delivered to your home in boxes with ice packs. Some are biodegradable, reusable, or recyclable. If conservation is important to you, be sure to check.
