Optavia Nutritional Plan – Diet Based on Food in Powder Form

Daily, the magazine "U.S. News" publishes a ranking of the nutritional plans available in the market. For years, the Mediterranean, DASH, and Flexi diets have been regarded as the best. Their effectiveness has been confirmed by numerous researchers, and the number of supporters continues to grow. Nevertheless, there could be no list of nutritional plans that were definitely less beneficial to health, but are applied due to the promises of the creators about fast results. One of the last positions in the ranking (21. out of 24) is occupied by the Optavia nutritional plan, which has not yet gained much popularity in Poland, but has made a significant impact in the United States. According to the magazine "U.S. News", it receives a rating of 1.8/5, while the Mediterranean diet has achieved a score of 4.6/5.

1. The Optavia Nutritional Program – what exactly is it?

The Optavia Diet is a nutritional program developed by Medifast Inc. in 2017. Its goal is to help individuals develop healthy eating habits and maintain them long-term. The program comprises four elements: pre-made meals, individual coaching, a community, and a system that encourages healthy habits. Participants who wish to lose weight receive pre-made meals from the company, as well as individual support and guidance from a private coach. Furthermore, they can join the community, which is a type of support group where they can share their experiences and help each other achieve their goals. However, not everyone is convinced of the program's effectiveness, despite it sounding interesting. Some argue that the diet is too restrictive and that the pre-made meals are not sufficient for those with a more active lifestyle.

2. How does it work in practice?

In practice, the process is divided into two stages: weight reduction and maintenance of results. In the first stage, it is recommended to consume 800-1000 calories per day for approximately 12 weeks. The standard model recommends consuming 5 meals purchased from the manufacturer every approximately 23 hours, as well as the inclusion of one home-cooked meal. A self-made meal should consist of 140-200g of lean meat or fish. In case of severe hunger, you can also consume half a cup of jelly, 3 loads of celery and nuts. The daily carbohydrate intake should not exceed 100 g. Preferred thermal processing methods are cooking, steaming, stewing and baking. The diet menu should include fish at least twice a week to provide the required amount of omega-3 fatty acids. It is also recommended to introduce at least 30 minutes of daily physical activity. After 12 weeks, the maintenance phase follows, where the calorie amount increases to 1550. Then whole grain products, low-fat dairy products or fruits can be introduced into the diet, and the optimal plan for this phase is 3 ready-made Optavia meals and 3 self-made meals. (M. Miller, 2021)

3. Are there any expenses linked to the Optavia diet?

On the Optavia diet website, one can directly purchase products developed by Medifast Inc. For a recommended 5 & 1 diet plan, the cost of a set that is sufficient for just over 3 weeks and consists of 119 meals is $395.25, which gives about PLN 1,660. Of course, the expenses of self-prepared meals should be added to this. One can also opt to create an individual set, but then the cost is significantly higher. However, to achieve the anticipated outcomes, an additional outlay of $199 (about PLN 835) is required, since the package provides access to the food plan, online platforms, the Optavia community, and the option to collaborate with a coach. In 2021, the average Pole spent a monthly amount of PLN 1316, of which 27% (PLN 355) was allocated to food (GUS 2022). Therefore, it is evident that this is not a diet that everyone can afford.

4. The might of the Optavia programme

Proponents of the Optavia programme emphasize a variety of benefits. The most evident benefit is its simplicity. It requires the preparation of just a single meal per day independently, the rest are foods that can be consumed instantly or potentially hydrated. Each plan also incorporates meals and guidelines, further simplifying the process. An indisputable factor that could encourage the adoption of the Optavia diet is the speed of weight loss. The energy deficit produced during its course is considerable enough to enable significantly faster weight loss than most nutrition methods. In the 'U. S. News' ranking in the 'best rapid weight loss diets' category, Optavia places 5th. Furthermore, due to its elevated protein content (up to 35%), it is a nutrition method that permits extended sensations of fullness. The diet's creators also point to a diminished risk of developing hypertension due to diminished sodium intake and weight loss.

5. Are there risks associated with utilizing the diet program?

Despite the claims of the authors that their diet leads to slow changes, their plan suggests something completely different. Consuming 800-1000 calories per day allows for a very rapid weight loss, but can also lead to a very quick yo-yo effect. Basal metabolic rate (PPM), which is the amount of energy the body needs to maintain basic life functions, is about 1200 calories for a 50 kg woman. If the consumed calorie amount is lower than the PPM, it can lead to severe undernourishment and numerous health problems, as well as a loss of lean body mass. Another issue is the type of proposed meals. A powdered meal diluted with water cannot replace a real, homemade meal. Furthermore, these products may contain various preservatives and substances that are not necessarily health-promoting. This type of food is not thoroughly researched, making it difficult to predict the long-term effects of its consumption.

6. Overview

The Optavia diet is a mode of nourishment that undeniably attracts with its promises of rapid outcomes and weight reduction. In truth, upon initial observation, the entire program appears to be meticulously pondered and expertly devised. However, in our perpetually exhausted and hasty times, pre-made solutions involving water-dissolved powders readily garner their advocates. Unfortunately, such modes of nourishment are associated with numerous adverse consequences, and equally importantly, they do not yield long-term results. Hence, it is advised to eschew such solutions and instead opt for a nutritious, balanced diet founded on whole-grain products, fruits, vegetables, and quality protein and fat sources.
