Type: Prepared meals | Weekly menu choices: 35+ entrées | Add-ons: Breakfasts, snacks, smoothies, juices, proteins | Meal plans: Calorie Smart, Chef's Choice, Keto, High Protein, Carb Conscious, GLP-1 Balance, Fiber Filled, Flexitarian | Servings: 1 | Shipping: $10.99

Factor, which made our top overall pick for the best keto meal delivery service, offers a unique, free 20-minute virtual coaching session with a registered dietitian, setting the service apart from competitors. Along with expert support, you'll find meal options for a range of diets — all crafted for maximum convenience.

Meals arrive fresh and fully cooked. Simply place them in the microwave for two minutes, and voilà! A nutritious meal with zero prep work. Since the meals are crafted with fresh, high-quality ingredients, they taste like they could be made in your own kitchen, and nothing like many of the frozen meals you'll find at the grocery store.

We tested a variety of options — including nonketo ones — and particularly enjoyed the Pulled Chicken Taco Bowl, Caribbean-Spiced Tofu With Black Beans and Rice, and Mango Salsa Salmon With Coconut Rice, Black Beans and Roasted Broccoli. Most of the meals are higher in protein than competitors' options, and you can filter your meal selections by protein, calorie and carb content. Nowicki warns that many meals are high in sodium, which may not be suitable for everyone, so ask your doctor if you're concerned.

Pricing for meals ranges from $10.99 to $13.49 per serving, depending on the number of meals ordered per week. Factor also offers assorted add-ons like breakfast items, snacks, smoothies, juices and cooked proteins.

A distinctive feature of Factor is its unwavering commitment to using high-quality ingredients. The company has an "Every Meal Matters" policy. It carefully sources premium ingredients and works closely with food suppliers and animal welfare experts to prioritize ethical and humane practices.

The majority of the packaging can be recycled. Factor's food tray material is CPET (crystallizable polyethylene terephthalate), a BPA-free plastic labeled No. 1 for recycling. The company also provides instructions on properly recycling the packaging, ensuring you can enjoy your meals guilt-free.

Green Chef was our overall favorite meal kit delivery service for weight loss thanks to its high-quality ingredients — many of which are organic — and flavorful dishes, including options for specialty diets like Mediterranean, keto and plant-based. While many recipes require basic knife skills and multitasking, they're generally easy to prepare. Some even come with pre-chopped or even precooked items to help cut down on prep time. 

Another highlight? Your subscription includes access to expert advice. "Green Chef even offers free 20-minute nutrition sessions with a registered dietitian (RD) to help make menu selections and discuss nutrition and health goals. This is especially helpful for people hoping to lose weight healthily and sustainably," says Blake.

The service has an expansive menu, with over 40 new meal options each week. A few of our favorites were the Coconut Shrimp Soup, Chicken Fajita Tacos With Creamy Chimichurri and Truffle Linguine. Just be aware that some meals are considered "premium" and add $7 to $10 per serving to your bill. You'll also want to keep an eye on nutrition stats, as some menu items are high in calories and saturated fat. 

The company, which is owned by the meal kit service HelloFresh, has earned certification from the U.S. Department of Agriculture as an organic company, ensuring that, at the very least, all the produce provided in your meal kit is organic unless stated otherwise. Additionally, the company is accredited by California Certified Organic Farmers.

Type: Freshly prepared meals | Weekly menu choices: 20+ entrée and breakfast meals | Add-ons: Bulk proteins and vegetables | Meal plans: Chef Selected, My Choice | Servings: 1 | Shipping: $9.99

Trifecta earned our pick as the best overall prepared meal delivery thanks to its comprehensive approach to weight loss and overall wellness. In addition to macro-balanced prepared meals, the service offers tracking tools and community forums to support your weight journey. The meals themselves are impressive, featuring high-quality plant- or animal-based proteins, healthy fats and plenty of fresh produce, most of which is organic. 

The company also wins high marks for its commitment to sourcing ingredients for its meals from small, local, organic farms while ensuring all proteins are produced using free-range, humane methods and seafood is responsibly wild-caught. Trifecta also offers bulk portions of precooked meat, fish, veggies and grains for meal planning, providing even more flexibility and customization for customers who prefer to create meals to suit their individual needs and tastes. This focus on quality is echoed in user reviews, with many customers praising the taste and nutritional balance of the meals.

Trifecta makes sticking to your health goals simple with easy recipe filtering by dietary preferences such as keto, paleo, pescatarian, vegan, vegetarian and more. Some of our favorite meals were the Teriyaki Chicken With Avocado and Broccoli, Spiced Turkey With Cauliflower Rice, and Tofu Fried Rice With Pineapple and Vegetables.

Meals start at $16 each, and you can mix and match entrées or choose from one of five chef-curated plans. While the price is a bit higher than some competitors', Trifecta's premium ingredients and built-in weight loss support tools justify the cost.

Trifecta also has a focus on sustainability. Most of the packaging is either 100% biodegradable or curbside recyclable.

Type: Meal kits and prepared meals | Weekly menu choices: 16+ meal kits, 16+ prepared meals | Add-ons: Breakfasts, grocery items | Meal plans: 1 main menu with diet-specific filters | Servings: 1, 2 or 4 | Shipping: Free for orders $100+; $12 for smaller orders

Weight loss doesn't have to revolve around meat and vegetables alone. In fact, research supports plant-based diets as an effective and sustainable approach to both weight loss and long-term health. Whether you're committed to a vegan lifestyle or just aiming to eat less meat, Purple Carrot is an excellent choice.

Purple Carrot specializes in plant-based meal kits and prepared heat-and-eat meals. Unlike others on our list, the company doesn't offer different meal plans. Instead, you can filter meal options by dietary preferences, including meals under 600 calories, gluten-free, high-protein, low-sodium, high-fiber, nut-free and soy-free. Meal options include breakfast, lunch and dinner entrées. There are also "Plantry" add-on options, such as matcha cold brew coffees, fresh juices, instant lentils, homestyle chili, plant-based crab cakes, juice shots, chocolates, nuts, crackers and vegan cheeses. 

This service distinguishes itself with its commitment to providing plant-based, flavorful dishes and creative ingredient combos — plant-based New England "Lobster" Rolls, anyone? Some of the standouts during testing included the Caper Dill Bagels With Everything Cream Cheese, Chipotle Tofu Tacos With Radish Escabeche and Cilantro Crema, and Crispy Lemon Chik'n With Brown Rice and Gia Lan. We also tried — and loved — the Thai Peanut Noodles With Tofu and Broccoli prepared meal and three juices from the Plantry: Eternal Life, Super Destroyer and Lean & Clean.

Purple Carrot's pricing ranges from $11 to $13.25 per serving, depending on the number of meals and servings ordered. Most of Purple Carrot's packaging is recyclable or compostable, which is a plus for those trying to reduce their carbon footprint further.

Type: Meal kits | Weekly menu choices: 100+ entrées | Add-ons: None | Meal plans: Gluten-Free Friendly, Low Calorie, Low Carb, Picky Eater Approved, Quick & Easy, Vegetarian | Servings: 2 or 4 | Shipping: $10.99

Dinnerly earns the top spot for the best budget-friendly weight loss meal service because of its affordable pricing and user-friendly approach to meal kits. According to registered dietitian Megan Huff, "Dinnerly is affordable and offers low-calorie and low-carb meal options that can help you meet your weight loss goals; ingredients are preportioned for each recipe and nutrition facts are provided." Plus, you'll find the service offers a wide variety of meal-kit menu options each week, such as dairy-free, low-calorie, low-carb, healthy and vegetarian. 

The meal kits are designed to be beginner-friendly, with an average of only five ingredients and simple instructions, which is ideal if you're new to cooking or pressed for time. The meals feature familiar flavors and are generally ready in under 30 minutes. We liked the Teriyaki Beef With Coconut Rice, Low-Cal Pork and Feta Meatballs With Crispy Romaine and Pita Salad, and Turkey Enchilada Bowl.

In terms of pricing, Dinnerly offers meals for as low as $5.99 per serving, making it one of the most affordable options in the meal kit market. This affordability does not compromise the variety of meal options, as there are over 100 recipes to choose from each week. Since healthy eating can be more expensive, Dinnerly's commitment to affordability makes sticking to nutritious meals eaiser to manage for those on tight budgets. One unique feature of Dinnerly is its digital recipe cards. While this may be a drawback for some, it reduces paper waste and allows easy access to recipes on the go.

Dinnerly prioritizes sustainability with eco-friendly packaging and detailed recycling instructions. It works with suppliers to use paper from sustainably managed forests and biodegradable natural fiber insulation, but packaging may vary depending on where you live.

Type: Frozen prepared meals | Weekly menu choices: 150+ entrées | Add-ons: Snacks | Meal plans: Signature, Gluten Free, Heart Healthy, Keto Flex, Diabetic, Menopause, Vegan | Servings: 1 | Shipping: $19.95

BistroMD stands out for its chef- and doctor-designed meal plans, which cater to various health goals. Nowicki says BistroMD is a top pick not just for weight loss but also for managing various health conditions. "Their meals are well-balanced and flavorful," she says. The company was cofounded by Dr. Caroline Cederquist and her husband, Edward, with one goal: to provide healthy, wholesome, balanced nutrition and assist with weight management. 

On the Signature plan, meals contain about 40% protein (about 25 to 30 grams), 30% healthy fats and 30% low-glycemic carbohydrates and fiber to help you feel full and keep your blood sugar levels stable. Plans for women are roughly 1,200 calories per day, including three meals and two snacks, while plans for men come in at 1,400 calories per day, including three meals and three snacks. This daily caloric intake is on the lower side, so discuss these plans with your doctor or registered dietitian before committing, as your calorie needs may be higher.

BistroMD's meals are fully cooked and can be heated in the microwave in just five minutes, which earns it top marks for convenience. The meals come frozen to maintain freshness and can stay in the freezer until it's time to eat. We're not going to lie; these meals weren't at the top of our list for flavor or texture — many of them had softer consistencies thanks to being frozen and thawed. That said, some were tastier than others, including the Grilled Salmon With Creamy Pesto, Spinach and Feta Stuffed Chicken, and Tofu Pad Thai With Sugar Snap Peas.

The Signature program includes seven days of meals — seven breakfasts and lunches and six dinners — and is priced at $220 before introductory discounts. You can also choose to receive just five days of meals or only lunches and dinners. 

One of the unique features of BistroMD is its team of dietitians, who provide support throughout your weight loss journey via your private client portal, where you can ask questions and set goals. This additional service enhances the user experience and provides valuable guidance on your quest to lose weight.

BistroMD's meals are insulated and shipped with dry ice. They come in microwave- and oven-safe (up to 400 degrees Fahrenheit) CPET plastic trays, sealed with light plastic covers for freshness. The trays, covers and cardboard sleeves are recyclable.

Type: Prepared meals | Weekly menu choices: 100+ entrées | Add-ons: None | Meal plans: 1 main menu with diet-specific filters | Servings: 1 | Shipping: $9.99

CookUnity is an excellent choice for busy foodies focused on weight loss, thanks to its diverse menu options — all of which are fully prepared and crafted by award-winning chefs, including some from the Food Network. The service also stands out for catering to a variety of dietary needs, including keto, gluten-free and plant-based options. Just be aware that some entrées are high in calories, saturated fat and sodium, so you'll want to pay close attention to nutrition stats before selecting your meals.

Another feature that sets CookUnity apart is that each meal not only is designed by a well-known chef, but also includes the chef's bio. After you've tried a few meals by each chef, you may find that you have a favorite chef and may be more inclined to try new meals and flavors from that chef that you might not have otherwise selected. A few of our favorite meals were the Teriyaki Tofu Bowl With Pineapple, Veggies and Brown Rice, Mongolian Salmon With Rice and Bok Choy, and West African Kale Salad With Fonio, Mango and Black-eyed Peas.

The plans offer flexible pricing based on the number of meals you choose per week. Prices start at $13.59 per meal for four meals a week, dropping to $12.29 for six meals, $11.69 for eight meals, $11.19 for 12 meals and $11.09 per meal for 16 meals a week.

CookUnity uses eco-friendly packaging and has committed to reducing carbon emissions.

Type: Meal kits and prepared meals | Weekly menu choices: 5,000+ recipes to choose from | Add-ons: Large selection of grocery items | Meal plans: 1 recipe database with diet-specific filters | Servings: 1, 2 or 4 | Shipping: Free for orders $70+; $6.99 for smaller orders

Want to receive healthy groceries, like snacks and breakfast items, in addition to dinner or lunches? Look no further than Hungryroot. Its unique approach combines recipes with their preportioned ingredients along with extra (optional) grocery items, providing a wide range of meals and snacks. 

Dietitian Sarah Wagner of Memorial Hermann Health System explains that this type of service may help take the mental work out of meal prepping by giving you a set menu for the week, which she says is a big barrier for people who want to start cooking more home meals but aren't used to the process. "They're a good starting place for people who are used to relying on less balanced meals, frozen dinners or fast food restaurants," she adds. 

Hungryroot offers a variety of diet focuses, such as vegan, vegetarian, pescatarian, allergen-free, 500 calories or less, carb-conscious and kid-friendly choices. The service offers meal kits and a variety of grocery items to fill in the gaps between meals. It has healthy snacks like baby carrots and grapes and even a ready-to-eat breakfast burrito. 

Our main gripe? Because convenience is the main focus, some recipes were lacking in the flavor department or didn't seem as nutritionally balanced as those you'd get from one of the other meal kit services on our list. 

When you order a Hungryroot box, it comes with recyclable cold packs called EnviroIce to keep perishable items fresh. You also receive a paper printout with your weekly recipes, making it easy to follow along, and there is a guide included to help you use up any extra ingredients.
