Background After 5 years, most reports show that less than 10% of people maintain a 5% loss from initial body weight. Weight maintenance after 10 years is rarely assessed, especially in commercial programs. The current article reports weight maintenance in individuals who had participated 2 to 11 years earlier in a popular commercial weight loss program based on Canada's Food Guide called Mincavi. Methods Randomly picked subjects answered a telephone questionnaire. Participants, 291 adult women from various regions of the province of Quebec, had followed the program 2 to 11 years earlier for at least a month. Body weight at the beginning and at the end of treatment was recorded as well as actual weight, age and height. Existing records allowed partial verification of the sample. Results Based on corrected weights, percentage of women who maintained at least 5% of their initial weight loss are as following; 2 years = 43.6% (n = 55), 3 years = 33.3% (n = 42), 4 years = 23.8% (n = 42), 5–6 years = 38.2% (n = 55), 7–8 years = 29.4% (n = 51), and 9–11 years; 19.6% (n = 46). Five to eleven years after they had participated in the program 29.1% of all women maintained a weight loss of at least 5%, while 14.3% maintained a loss of at least 10%. Conclusions Even though success rate is not as high as could be wished for, results show that participation in the Mincavi program can lead to effective weight maintenance long after individuals have left it. These findings suggest more thorough studies should be conducted on this weight loss program.

This statistic depicts the percentage of U.S. adults that tried to lose weight using various methods from 2013 to 2016. According to the data, during that time 50.4 percent of those trying to lose weight ate more fruits and vegetables or salads to lose weight.

Objectives: Characterize patterns of weight change among subjects with obesity. Methods: A retrospective observational longitudinal study of subjects with obesity was conducted using the General Electric Centricity electronic medical record database. Subjects who were ≥18 years old with BMI ≥30 kg/m2 (first defining index BMI), had no medical conditions associated with unintentional weight loss, and had ≥4 BMI measurements/year for ≥2.5 years were included and categorized into groups (stable weight: within <5% of index BMI; modest weight loss: ≥5 to <10% of index BMI lost; moderate weight loss: ≥10 to <15% of index BMI lost; and high weight loss: ≥15% of index BMI lost) based on weight change during 6 months following index. No interventions were considered. Patterns of weight change were then assessed for 2 years. Results: A total of 177,743 subjects were included: 85.1% of subjects were in the stable weight, 9.3% in the modest, 2.3% in the moderate, and 3.3% in the high weight loss groups. The proportion of subjects who maintained or continued to lose weight decreased over the 2 year observation period; 11% of those with high weight loss continued to lose weight and 19% maintained their weight loss. This group had the lowest percentage of subjects who regained ≥50% of lost weight and the lowest proportion of subjects with weight cycling (defined as not continuously losing, gaining, or maintaining weight throughout the 2 year observation period relative to its beginning). This trend persisted in subgroups with class II–III obesity, pre-diabetes, and type 2 diabetes. Conclusion: Weight cycling and regain were commonly observed. Subjects losing the most weight during the initial period were more likely to continue losing weight.

The online weight loss industry has experienced dynamic shifts in recent years, shaped by growing consumer awareness of the links between weight management and chronic health conditions and rapid technological adoption. The pursuit of digital services reflects a preference for convenient, customizable wellness options over traditional in-person consultations. Increasingly, users seek programs that offer flexible diets, integrated wellness features and real-time support, moving away from highly restrictive plans or prepackaged meals. Intensifying competition, notably from the popularity of prescription-based therapies such as GLP-1 drugs, has prompted digital platforms to diversify offerings, including virtual medical consultations and tailored interventions. Innovations in artificial intelligence and user-centric digital tools continue to elevate user experience, accelerate program personalization and expand market reach across a more fragmented competitive landscape. Total industry revenue has dropped at a CAGR of 1.2% to $1.5 billion, including an expansion of 1.9% in 2025 alone.

With minimal investment in physical infrastructure and lower rent, overhead has remained contained, allowing providers to prioritize digital product development and customer engagement. Companies have stabilized wage costs through remote staffing and automation while keeping marketing expenses proportional to revenue growth by relying heavily on digital channels. However, investment in vitamins, supplements and prepared meal kits keeps purchase costs a considerable share of expenditure, particularly as companies expand their portfolios to attract broader audiences. While intensified rivalry and the emergence of agile newcomers challenge established brands, strategic procurement agreements, operational efficiency and scalable service delivery continue to support steady gains in profit, even as consumer preferences evolve and new regulations emerge. The market is poised for continued expansion, driven by mounting health and wellness concerns and increasing obesity rates nationwide. Economic recovery and rising disposable income are expected to sustain demand for personalized and holistic digital solutions. Companies will likely focus on building credibility through science-backed content, transparent data practices and diversified expert support to address growing user skepticism. Anticipated logistics and smart distribution investments will require tighter supplier relationships and optimized fulfillment operations as order volumes climb. The industry’s adaptive approach to evolving health trends, consumer expectations and technological advances positions it for robust performance over the next five years. Online weight loss revenue is forecast to rise at a CAGR of 1.9% to reach an estimated $1.7 billion in 2030.

The Diet segment is estimated to witness significant growth during the forecast period. The market is driven by the growing concern over health issues related to visceral fat, weight fluctuation, and obesity. Obesity, characterized by a body mass index (BMI) of 30 or higher, affects over one-third of the global population. This condition can lead to various health complications, including high blood pressure, joint problems, diabetes, and insulin sensitivity issues. To combat these health concerns, weight loss programs focusing on calorie expenditure through diet and physical activity have gained popularity. Diets, specifically, dominate the market, as they offer a more sustainable approach to weight management. Nutritional counseling and micronutrient intake are essential components of effective weight loss programs, ensuring a balanced macronutrient and micronutrient intake. Obesity rates continue to rise, fueling the demand for

IntroductionDietitians are the preferred primary health care professionals for nutritional care in overweight patients. Guidelines for dietitians recommend a weight reduction of ≥ 5% of initial body weight after one year of treatment. The purpose of this study was to evaluate weight change in patients with overweight who were treated by dietitians in Dutch primary health care, and to identify patient characteristics that were associated with it.Materials and methodsThis observational study data was based on real life practice data of patients with overweight during the period 2013–2017, derived from dietetic practices that participated in the Nivel Primary Care Database. Multilevel linear regression analyses were performed to investigate weight change after dietetic treatment and to explore associations with patient characteristics.ResultsIn total, data were evaluated from 56 dietetic practices and 4722 patients with a body mass index (BMI) ≥ 25 kg/m2. The mean treatment time was 3 hours within an average timeframe of 5 months. Overall, patients had a mean weight change of -3.5% (95% CI: -3.8; -3.1) of their initial body weight, and a quarter of the patients reached a weight loss of 5% or more, despite the fact that most patients did not meet the recommended treatment duration of at least one year. The mean BMI change was -1.1 kg/m2 (95% CI: -1.2; -1.0). Higher weight reductions were shown for patients with a higher initial BMI and for patients with a longer treatment time. Sex and age were not associated with weight change, and patients with other dietetic diagnoses, such as diabetes, hypertension, and hypercholesterolemia, had lower weight reductions.ConclusionsThis study showed that dietetic treatment in primary health care coincided with modest weight reduction in patients with overweight. The weight loss goals were not reached for most patients, which was possibly due to a low treatment adherence.
