Diet boxes have become essential in recent years. They operate on a simple idea: delivering everything you need to follow a specific meal plan directly to your home.

Their promise? To help you lose weight without the hassle. Generally, these boxes include pre-portioned servings for each meal that you only need to complete with fruit, fresh vegetables, and sometimes dairy products, according to the provided recommendations.

To provide even more support, some plans include monitoring by a nutrition professional, such as a dietitian and a fitness coach. This duo allows the program to be personalized to your needs and maximizes your results.

However, not all boxes are equal. To help you see more clearly, we conducted an in-depth study of the 7 main weight-loss programs, compared according to 3 criteria.

We evaluate all boxes independently. If you click on one of the provided links, a commission may be paid to us, without affecting the price or the ranking.

Methodology and comparison criteria

To compile this comparison, I identified 3 qualitative criteria based on the characteristics of the programs. Each criterion is rated out of 5, and the average of the 3 scores determined my final score and ranking.

1. Nutritional quality of the meals offered

One of the key points to consider is the content of the meals. These take different forms: freeze-dried pouches, canned meals, or fresh meals. Among them, fresh meals stand out for their higher nutritional density, providing greater amounts of vitamins and essential nutrients. This characteristic gives them a privileged place in this comparison.

Moreover, I carefully evaluated the quality of the ingredients used, giving particular importance to fresh products from local supply chains or organic farming. This choice highlights not only the nutritional qualities, but also the environmental impact and the traceability of the meals. 

When brands specify the origin of the ingredients, it provides an additional guarantee of transparency and reliability.

Another key criterion is the absence of additives, GMOs and artificial colorings, ensuring healthier dishes that meet the expectations of health-conscious consumers.

Finally, the diversity of the menus offered has been carefully examined. A varied meal plan is essential to avoid monotony and to meet all nutritional needs.

The inclusion of specific options, such as dishes suitable for vegetarian or gluten-free diets, reflects special attention to dietary restrictions and consumer choices.

2. Customer experience

The user experience is not limited to the simple contents of the boxes, but encompasses the entire journey offered by the brand.

For example, some companies offer a mobile app. It can be very useful for choosing menus, tracking weight changes, or for receiving real-time advice. 

The program may also include regular appointments with professionals, such as dietitians or fitness coaches, which adds a human and personalized dimension to the support.

Moreover, motivation tools, such as mutual support community groups on social networks, help strengthen user engagement. These groups, often present on Facebook, allow users to share their successes, exchange advice, or simply find moral support, which can make a big difference in the success of a weight loss program.

3. Professionalism and reliability of the brand

A brand’s reputation plays a decisive role in choosing a box. 

Brands with a long-standing presence in the market generally inspire more trust, as they demonstrate longevity and an ability to adapt to consumer expectations. 

I also took into account their presence and reputation on social media, by looking at their number of followers.

Customer reviews left on Trustpilot provide valuable insights into user satisfaction and the quality of meals and service.

Finally, the responsiveness of customer service was evaluated by sending an email to support. The speed and completeness of the reply, in my opinion, are indicative of a stronger or weaker level of commitment from each company.

5. La Brigade de Véro

Founded in 2017 in the Montpellier region, La Brigade de Véro offers deliveries of fresh meals designed to support weight loss or weight maintenance, while adapting to the specific needs of its clients.

La Brigade de Véro stands out for its 100% homemade dishes, guaranteed without additives or preservatives. The recipes change with the seasons and are developed from fresh, local, and sourced ingredients.

A major asset of the brand is its transparency: every ingredient used is traceable, and the majority of the products come from the southwest of France. I find this transparency very valuable, it offers an assurance of quality and reliability.

La Brigade de Véro offers a wide range of programs that adapt to each individual’s goals and dietary preferences. Among the available options, you can choose, among others:

• A low-carb program or one high in fiber 
• A vegetarian program.
• A plan without pork or fish 
• Adaptation based on activity level (sedentary or active).

Breakfasts and snacks are also fresh and sometimes homemade or from small artisanal businesses and often local. They may include artisanal pastries, dairy products, or carefully selected fruits, offering a gourmet touch to the program.

Meals are delivered once a week by refrigerated truck, ensuring the freshness of the dishes.

The standard La Brigade de Véro program provides a caloric intake of 1,200 kcal per day. To cover each client’s specific needs, it is recommended to supplement the meals with fresh fruits, vegetables, and dairy products.

Throughout the program, a dietitian is available by email to answer questions, adjust the program and maintain motivation. A private Facebook group, bringing together more than 7,300 members, also allows clients to share their experiences and support each other in their weight-loss journey.

To take its health approach further, La Brigade de Véro offers a 4-month program that includes a blood test at the start and at the end of the program, allowing assessment of its impact on health, and comprehensive monitoring via an app.

6. Comme J’aime

Founded in May 2010, Comme J’aime is a French brand specializing in the delivery of “turnkey” meals to support weight loss. It has established itself as a reference in the field thanks to a significant media presence, notably with television commercials featuring well-known public figures.

Comme J’aime offers standardized 7-day programs, including 4 meals per day: breakfast, lunch, afternoon snack and dinner. However, there is little flexibility in the options offered. The only possible customizations concern specific diets, such as: meat-free, fish-free, vegetarian…

The meals are delivered all at once for the entire program, with no option to choose individual meals.

The offer includes 75 different dishes as well as 14 breakfast and snack options. The dishes are made in France, guaranteed free of GMOs and preservatives. The meats used are of French origin.

Lunch generally consists of a sealed, shelf-stable dish and dinner is often lighter, with freeze-dried dishes to rehydrate, such as soups or purées. They can all be stored at room temperature.

The programs offer days at 1,200 – 1,300 kcal, to which it is recommended to add fruit and dairy products to achieve a balanced caloric intake.

In addition to the meals, Comme J’aime offers support to monitor and encourage its clients:

• A mobile app that allows you to track weight progress, access advice, and stay motivated.
• A dietary follow-up provided by dietitians and weight-loss coaches.

However, unlike other brands, Comme J’aime does not offer a community support group on platforms like Facebook. Only an official page is available, intended for brand communication.

The brand benefits from strong visibility on social networks with more than 15,000 followers on Instagram and 103,000  on Facebook.

On the review site Trustpilot, Comme J’aime has an average rating of 3.9/5 from over 4,800 reviews. The positive points mentioned include the quality of the meals and the professionalism of customer service. However, some recurring criticisms cite the high price of the programs and financial penalties in case of early termination.

Customer service is responsive and responds effectively to questions. However, I observed a notably insistent sales approach, strongly pushing for the purchase of the program.

7. Régime Box

Régime Box is a French brand belonging to the same group as Comme J’aime.

Unlike Comme J’aime, Régime Box allows selecting dishes before payment confirmation, offering customization tailored to each user’s dietary preferences.

The meals offered are the same as those offered by Comme J’aime and follow a fixed format, but with a well-defined composition: 1 breakfast, 1 prepared dish for lunch, 1 snack, 1 soup and 1 freeze-dried pouch meal for dinner.

In addition to the meals, Régime Box offers an initial assessment with a weight-loss coach and personalized follow-up provided by a dietitian, to support users throughout their program.

With an average rating of 3.1/5 based on 147 reviews, Régime Box receives mixed feedback.

Most customers praise the simplicity and effectiveness of the programs offered; however, other reviews mention the poor taste of the dishes, the lack of variety in the menus, and recurring delivery issues.

Régime Box lacks visibility on social media, with only 18 followers and an almost inactive page. However, customer service is very responsive: despite the phone line sometimes being busy, advisors call back quickly and answer questions clearly.

One of Régime Box’s main advantages, in my opinion, is its competitive pricing.

Weight-loss programs: FAQ

Is it possible to lose weight quickly with a weight-loss program?

Yes, these boxes, based on a large calorie deficit, can lead to rapid weight loss. However, losing weight too quickly can be harmful to your health and difficult to maintain over the long term. It is preferable to opt for a gradual, balanced approach.

Moreover, weight gain is often a symptom of an underlying problem: poor understanding of nutritional needs, an altered relationship with food, metabolic imbalances, etc. While slimming boxes can be effective in the short term, they do not address the real causes. That is why weight often returns at the end of the program.

How long do you need to follow a weight-loss program to see results?

It depends on the individual and the goals. Results can be visible within a few weeks if the program is well adapted.

What should I do if I don’t get the expected results with a weight-loss program?

Slimming boxes are generally very low in calories. If you are not losing weight, it may be due to excessive consumption of foods outside the planned meals or a metabolic disorder preventing weight loss. In that case, it is essential to consult a healthcare professional for appropriate support.

Are weight-loss programs safe for your health?

Well-supervised, personalized programs are generally safe. However, avoid methods that are too restrictive or not validated by professionals. Restrictive diets are ineffective in the long term, can cause nutritional deficiencies, and may promote the development of eating disorders.

How can I avoid regaining weight after finishing a weight-loss program?

To avoid the yo-yo effect, it is essential to:

• Maintain good eating habits,
• Engage in regular physical activity,
• Work on the relationship with food.

It is also important to adopt new eating habits by listening to your needs, desires, and hunger and satiety cues, without frustration.

Are weight-loss programs suitable for everyone?

No, each individual has specific needs. A program should be personalized according to health status, goals, and lifestyle. This type of program is not recommended for people suffering from eating disorders.

Do the restrictive diets in weight-loss programs lead to nutritional deficiencies?

Yes, overly restrictive diets can cause deficiencies. It is preferable to choose balanced programs that cover all your nutritional needs. Pre-packaged or freeze-dried meals, often used in these programs, are generally low in vitamins destroyed during their preparation. Therefore, it is important to add at least fresh fruits and vegetables.

Should you consult a doctor or a nutritionist before starting a weight-loss program?

Yes, it’s highly recommended. A professional can make sure the program is suited to your health and goals, thus avoiding any unnecessary risk.
