The quest for effective weight loss solutions is a continuous journey in the wellness world. Among the myriad of options, Nova weight loss programs and supplements have garnered attention. This article delves into a comprehensive review of Nova, examining scientific studies, user experiences, and potential benefits and drawbacks to provide a clearer understanding of its effectiveness.
Understanding the NOVA Food Classification System and Its Impact on Weight Management
The NOVA food classification system categorizes foods based on the extent of processing they undergo. This system is crucial in understanding the relationship between diet quality and health outcomes, particularly in weight management.
The NOVA Classification
The NOVA system categorizes foods into four groups:
- Unprocessed or Minimally Processed Foods: These include plant- and animal-sourced foods that have undergone minimal alterations, such as removal of inedible parts, chilling, freezing, pasteurization, fermentation, boiling, drying, or grinding, without the addition of salt, sugar, fat, or other substances.
- Processed Culinary Ingredients: Substances like oils, fats, sugars, and salt derived from Group 1 foods or from nature, used to season and cook foods.
- Processed Foods: Relatively simple products made by adding salt, sugar, or other substances to unprocessed or minimally processed foods. Examples include canned vegetables, fruits in syrup, and cheese.
- Ultra-Processed Foods (UPF): Formulations of processed food substances and cosmetic additives created by the industry as profitable and attractive alternatives to unprocessed or minimally processed foods.
The Link Between NOVA and Weight Management
Studies employing the NOVA system have frequently used the dietary share of UPF in calories or grams to assess diet quality and its impact on health. UPFs are often linked to several chronic diseases, including overweight and obesity, due to their attributes acting through known, plausible, or suggested physiologic and behavioral mechanisms. Conversely, a higher dietary contribution of unprocessed/minimally processed foods has been associated with a lower risk of overweight.
The NutriNet-Brasil Cohort Study: A Detailed Look
The NutriNet-Brasil cohort study, an ongoing web-based prospective study, provides valuable insights into the relationship between diet and health outcomes. Since January 2020, this study has continuously recruited participants aged 18 years and older to investigate the prospective association between diet characteristics and chronic non-communicable diseases in Brazil.

Methodology and Data Collection
Participants in the NutriNet-Brasil study complete a short 24-hour dietary recall screener, including 'yes/no' questions about the consumption of whole plant foods (WPF) and ultra-processed foods (UPF) at baseline. The Nova-WPF and Nova-UPF scores are computed by adding up positive responses regarding the consumption of thirty-three varieties of WPF and twenty-three varieties of UPF, respectively. Participants also report their height at baseline and their weight at both baseline and after approximately 15 months of follow-up.
Key Findings
The study revealed that increasing quintiles of the Nova-UPF score were linearly associated with a higher risk of BMI gain. Specifically, the relative risk of BMI gain in the highest quintile (Q5) compared to the lowest (Q1) was 1.34 (95% CI 1.15, 1.56). Conversely, increasing quintiles of the Nova-WPF score were linearly associated with a lower risk of BMI gain, with a relative risk of 0.80 (95% CI 0.69, 0.94) when comparing Q5 to Q1.
Implications for Weight Management Strategies
The findings from the NutriNet-Brasil cohort study underscore the importance of dietary choices in weight management. The direct association between higher UPF consumption and increased BMI gain, coupled with the inverse association between WPF consumption and BMI gain, suggests that strategies to prevent weight gain should promote diets rich in whole plant foods while minimizing the intake of ultra-processed foods.
The Nova 24-Hour Screener: A Tool for Assessing Diet Quality
The Nova 24-hour screener is a low-burden survey questionnaire designed to capture the consumption of unprocessed or minimally processed whole plant foods (WPF) and ultra-processed foods (UPF). This screener includes checkbox-format questions about the consumption of selected food items on the previous day.
Components of the Nova 24-Hour Screener
The screener includes thirty-three varieties of unprocessed or minimally processed WPF, such as vegetables (excluding potatoes and cassava), fruits (excluding fruit juice), whole-grain cereals, pulses, and unsalted nuts and seeds. It also includes twenty-three varieties of UPF, such as soft drinks, flavored dairy drinks, packaged chips, sweetened cereal bars, instant noodles, reconstituted meat products, and salad dressings.

Calculating Nova-WPF and Nova-UPF Scores
The Nova-WPF score is computed by adding up positive responses regarding the consumption of each of the thirty-three varieties of unprocessed or minimally processed WPF. The score ranges from zero to thirty-three. Similarly, the Nova-UPF score is computed by adding up positive responses regarding the consumption of each of the twenty-three varieties of UPF, ranging from zero to twenty-three.
Validation of the Nova 24-Hour Screener
A validation study of both scores was conducted in a random sample of 812 NutriNet-Brasil cohort participants using a full 24-hour recall as the reference dietary intake method. The prevalence-adjusted and bias-adjusted kappa (Pabak) index was used to assess the degree of agreement in the classification of participants according to the quintiles of the dietary energy share of WPF and UPF in the diet and quintiles of the Nova diet quality scores. A Pakab index greater than 0.80 indicates almost perfect agreement, while values between 0.61 and 0.80 indicate substantial agreement.
Practical Applications of the Nova 24-Hour Screener
The Nova 24-hour screener offers a simple and efficient method for assessing diet quality in large populations. Its low burden and ease of administration make it suitable for use in surveillance systems and cohort studies. By providing insights into the consumption patterns of WPF and UPF, the screener can help identify individuals and populations at risk of BMI gain and inform targeted interventions to promote healthier dietary choices.
Baseline Characteristics and BMI Change: Insights from the NutriNet-Brasil Study
The NutriNet-Brasil study provides valuable data on the baseline characteristics of participants and their association with changes in BMI over a 15-month period. This data helps to understand the factors that influence weight gain and the effectiveness of different dietary patterns.
Baseline Characteristics of Participants
The study included 9,551 participants, whose baseline characteristics were analyzed in relation to quintiles of the Nova dietary quality scores. Higher Nova-WPF scores were significantly associated with older age, higher education (≥12 years of schooling), not currently smoking, not being on a weight loss diet, physically active status, and having a lower BMI at baseline. Conversely, higher Nova-UPF scores were significantly associated with being male and younger, having lower education (<12 years of schooling), being insufficiently active, having a higher BMI at baseline, and living in the more economically developed South and Southeast Brazilian regions.

Association Between Nova Scores and BMI Change
Restricted cubic splines linear regression models revealed an inverse association between the Nova-WPF score and 15-month BMI change and a direct dose-response association in the case of the Nova-UPF score. Specifically, increases in quintiles of the Nova-UPF score and decreases in quintiles of the Nova-WPF score were both directly and linearly associated with an increased risk of BMI gain in all models.
Implications for Public Health
These findings highlight the importance of considering sociodemographic and behavioral factors in the design of weight management interventions. The association between higher UPF consumption and lower education, insufficient physical activity, and higher baseline BMI suggests that targeted interventions are needed to address these factors and promote healthier dietary choices among vulnerable populations.
Nova Health Supplements: An Overview
In addition to the NOVA food classification system, the term "Nova" also appears in the context of dietary supplements. Nova Health supplements are designed to enhance metabolism, support weight loss, and slow the signs of aging. While not specifically targeted at mental health, their holistic approach to wellness may offer indirect benefits beyond physical well-being.
How Nova Health Supplements Work
Nova supplements are formulated with a science-backed approach that focuses on enhancing the body’s natural processes. At the core of their effectiveness is autophagy, a vital process that helps the body renew itself by clearing out old, damaged cells and replacing them with fresh, healthy ones. This process supports metabolism and weight loss and plays a role in maintaining youthful skin, hair, and nails.
Key Ingredients
A standout ingredient in Nova is spermidine, which has been widely studied for its ability to activate autophagy and promote cellular health. Spermidine has been linked to enhanced longevity and vitality, helping the body maintain its youthful energy over time.
In addition to spermidine, Nova contains essential nutrients like thiamine (B1) and zinc, which work together to support energy production, metabolism, and immune function. Thiamine helps the body convert food into energy, while zinc supports immune health and contributes to a glowing complexion.

Novo Nordisk's Amycretin: A Promising Development in Obesity Treatment
In the pharmaceutical arena, Novo Nordisk is developing amycretin, a drug that stimulates two gut hormones, GLP-1 and amylin, affecting appetite and blood sugar levels. This drug is part of Novo's efforts to build on the success of its obesity drug Wegovy and compete with other pharmaceutical companies in the weight loss market.
Phase 1 Trial Results
In a Phase 1 trial, amycretin demonstrated significant weight loss results, with participants experiencing close to 13% weight loss after 12 weeks. While these results are promising, it is important to note that comparing drugs across trials can be challenging due to differences in study design and patient populations.
Market Competition and Manufacturing Capacity
The announcement of amycretin comes as Novo Nordisk faces increasing competition in the obesity treatment market. Eli Lilly has already won approval for Zepbound, and other companies are advancing their own prospects. If amycretin is successful in further trials and receives regulatory approval, Novo Nordisk's manufacturing capacity could become a limiting factor in its ability to meet market demand.
