The stages of change have been identified as a valuable framework for understanding the transition toward a healthy lifestyle. It is also important to recognize change through other psychosocial variables, such as motivation and self-efficacy. The objective of this study was to explore weight control over the course of an academic year (nine months) through three behaviors: the stage of change toward weight control (pre-contemplation, contemplation, preparation, action, maintenance), healthy and unhealthy eating behaviors for weight control, and the frequency of physical activity (PA). Furthermore, we wanted to ascertain whether the three distinct types of motivation (autonomous, controlled, and amotivation) and self-efficacy could account for fluctuations in weight control over time. The sample consisted of 303 adolescents (205 female and 98 male) between the ages of 15 and 23 (M = 17.26; SD = 1.65). Chi-square, t-test, and multiple linear stepwise regression analysis were employed. The results indicated that a higher proportion of adolescents were in the precontemplation and action stages at Time 2. Concurrently, an increase in the frequency of moderate-to-vigorous PA and an increase in healthy and unhealthy behaviors were observed during the school period. The present study posits that autonomous motivation, controlled motivation, and self-efficacy can explain healthy eating behaviors for weight control and the frequency of moderate-to-vigorous PA, while only controlled motivation explains unhealthy eating behaviors for weight control. The conclusion of the study points out that healthy behaviors can change over time due to individual regulation of motivation and increased self-perception of efficacy in one’s own abilities to perform a specific action to control weight.

Objective: This study aimed to evaluate the impact of an exclusively vegetarian diet, combined with physical activity and lifestyle interventions, on metabolic parameters in patients with metabolic syndrome, with a focus on preventing premature aging and improving overall health status. Materials and Methods: A total of 150 participants (82 females, 68 males; aged 36–80 years, with a mean age of 61.45 years) diagnosed with metabolic syndrome were enrolled. Participants followed an exclusively vegetarian diet (≈2100 kcal/day; 65% carbohydrates, 23% lipids, 15% proteins, 52.4 g dietary fiber, and 0 mg cholesterol) along with a structured lifestyle program that included physical activity (2.5 h/day, intensity 2–6 METs), psychological counseling, smoking cessation support, weight and blood pressure management, hydrotherapy, massage, phytotherapy, and stress-reduction sessions. Baseline and post-intervention assessments were performed to measure total cholesterol, LDL, HDL, triglycerides, glycemia, BMI, and blood pressure. Results: After 10 days of intervention, significant improvements were observed across all measured parameters: total cholesterol decreased by 41.21 mg/dL (−19.54%), triglycerides decreased by 72.86 mg/dL (−34.9%), LDL cholesterol decreased by 26.24 mg/dL (−19.71%), fasting glycemia decreased by 30.4 mg/dL (−21.61%), BMI decreased by 3%, systolic blood pressure decreased by 10.82 mmHg, and diastolic blood pressure decreased by 6.44 mmHg. Conclusions: Our findings demonstrate that a structured lifestyle intervention, centered on a vegetarian diet and physical activity, has a significant beneficial effect on metabolic health. This approach improves cardiovascular risk factors, glycemic control, and body composition, and may play a preventive role against premature aging. Full article

The double burden of malnutrition (DBM)—the coexistence of overweight/obesity and micronutrient deficiency—is an emerging public health concern among school-aged children. Using data from 6063 participants in Colombia’s 2015 National Survey of Nutritional Status (ENSIN), this study estimated DBM prevalence and identified factors associated with its occurrence among children aged 5–12 years. DBM was defined as concurrent overweight/obesity (BMI-for-age z-score > 1) and vitamin D deficiency, applying thresholds of <30, <37.5, and <50 nmol/L. The prevalence of DBM ranged from 0.7% to 6.9%. Firth’s penalized logistic regression models were conducted separately for (1) overweight/obese combined, (2) overweight-only, and (3) obesity-only groups. For DBM1, insufficient physical activity was linked to higher odds across all three models. For DBM2, smaller household size and higher maternal education were associated with greater odds in the combined model. Living in large urban areas was related to lower odds compared with major metropolitan areas, a pattern also observed in the overweight-only model. For DBM3, children from the second wealth quartile (Q2) showed higher odds than those from the poorest (Q1), with a similar pattern in the overweight-only analysis. Stricter DBM definitions tended to capture behavioral and household characteristics, whereas broader thresholds reflected structural and contextual conditions. Despite its relatively low prevalence, DBM remains a relevant public health issue among Colombian schoolchildren. Full article

Numerous reports have been published on the putative mechanisms of development of insulin resistance in diabetes mellitus. However, no unified view has been established yet, especially in regard to involvement of the nervous system in the regulation of insulin sensitivity. In this study, we investigated the involvement of the autonomic nervous system in cellular glucose uptake by blocking Group C nerve fibers (C fibers) in the rat pancreas with capsaicin. When the junction of the proximal pancreatic duct and common bile duct was treated with capsaicin, glucose uptake was enhanced, probably due to increased insulin sensitivity. This suggests that capsaicin may partially block the vagal nerve fibers innervating the pancreas, resulting in enhanced insulin sensitivity. In other words, our finding suggests that pancreatic autonomic nerves may be involved in the regulation of insulin sensitivity and that partial blockade of these nerves may improve insulin sensitivity.

L-fucose is a monosaccharide derived from brown algae and has potential applications as a functional food ingredient. Previous studies have reported that L-fucose reduces lipid accumulation in murine adipose tissue. Adipose tissue not only regulates energy metabolism but also functions as an endocrine organ involved in inflammation through the production and secretion of various adipokines. L-fucose is expected to exert anti-inflammatory effects and modulate adipokine secretion in adipocytes. In the present study, we investigated the anti-inflammatory effects of L-fucose in adipocytes. L-fucose significantly suppressed the expression of pro-inflammatory mediators and reduced the production of reactive oxygen species induced by inflammatory stimulation with a combination of lipopolysaccharide (LPS), tumor necrosis factor-⍺ (TNF-⍺), and interferon-γ (IFN-γ). These effects are likely mediated through the inhibition of key signaling pathways, including mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) pathways. Additionally, we found that L-fucose promoted the multimerization and secretion of high molecular weight (HMW) adiponectin, even under inflammatory conditions. Our results suggest that although L-fucose downregulates adiponectin expression, it contributes to the formation and/or stabilization of HMW adiponectin, which is functionally more relevant in anti-inflammatory and metabolic regulation. L-fucose thus holds promise as a functional food ingredient for mitigating inflammation in adipocytes. Full article

Obesity is closely associated with appetite dysregulation, influenced by behavioral, hormonal, and neurological factors. The Council on Nutrition Appetite Questionnaire (CNAQ) is a validated tool, translated into Arabic, but its application in weight-loss interventions remains underexplored. This secondary cross-sectional analysis evaluated whether the Arabic CNAQ can differentiate appetite levels after a 6-month telenutrition weight-loss intervention supported by telemonitoring and health coaching, and whether appetite is associated with weight-loss outcomes. A total of 36 participants were assessed: the intervention group (n = 21), who completed the program, and the control group (n = 15), who received no continuous support. Appetite was measured using the CNAQ after 6 months. Independent-samples t-tests and Mann–Whitney U tests were applied to compare appetite scores, while Chi-square tests were used for appetite categories. Results showed mean CNAQ scores of 27.87 (SD = 2.64) for the control group and 26.86 (SD = 4.46) for the intervention group (p = 0.402). Most participants reported moderate appetite (93.3% control; 76.2% intervention), with no significant between-group differences (p = 0.367). Although differences were not statistically significant, the findings demonstrate the feasibility of using the Arabic CNAQ in telehealth weight management. Larger studies with repeated measures are needed to confirm its utility in clinical and dietetic practice. Full article

Clozapine and olanzapine are important medications in the management of psychiatric conditions such as schizophrenia. However, metabolic disturbances and weight gain are common side effects of these drugs. We aimed to evaluate the effects of GLP-1 RAs treatment for metabolic disturbances and weight gain in patients on clozapine/olanzapine. For this systematic review, searches were conducted in eight different databases. After screening, outcome data was synthesized regarding weight gain and biochemical and clinical indicators of metabolic disturbance, as well as for adverse events/side effects, and any other benefits of GLP-1 RA treatment. A total of 14 studies were included in this medical systematic review, of which four were unique randomized control trials (RCTs), with study contexts including Australia and Denmark. GLP-1 RAs that were utilized include semaglutide, exenatide, and liraglutide. It was consistently demonstrated across studies that, when followed-up, those on GLP-1 RAs had achieved statistically lower levels of weight gain compared to those receiving placebo. A similar effect was seen on fasting glucose levels and glycated haemoglobin levels. Effects on other metabolic parameters were inconsistent. There were minimal gastrointestinal, psychological, cardiac, and other side effects noted across studies. GLP-1 RAs may offer utility in addressing the metabolic side effects of olanzapine/clozapine, but further research is needed. There remains a need to better understand impacts and potential side effects in larger and more diverse populations, as well as a need to better evaluate the long-term outcomes for patients.

Non-communicable diseases (NCDs) are the leading global cause of death, causing over 43 million deaths in 2021, including 18 million premature deaths, disproportionately affecting low- and middle-income countries. NCDs also incur significant economic losses, estimated at USD 7 trillion from 2011 to 2025, despite low prevention costs. This study evaluated body mapping indicators: body mass index (BMI), waist circumference, and waist-to-hip ratio—for predicting NCD risk, including hypertension, diabetes, and cardiovascular diseases, using data from a nationally representative survey in Ghana. The study sampled 5775 participants via multistage stratified sampling, ensuring proportional representation by region, urban/rural residency, age, and gender. Ethical approval and informed consent were obtained. Anthropometric and biochemical data, including height, weight, waist and hip circumferences, blood pressure, fasting glucose, and lipid profiles, were collected using standardized protocols. Data analysis was conducted with STATA 17.0, accounting for complex survey design. Significant sex-based differences were observed: men were taller and lighter, while women had higher BMI and waist/hip circumferences. NCD prevalence increased with age, peaking at 60–69 years, and was higher in females. Lower education and marital status (widowed, divorced, separated) correlated with higher NCD prevalence. Obesity and high waist circumference strongly predicted NCD risk, but individual anthropometric measures lacked screening accuracy. Integrated screening and tailored interventions are recommended for improved NCD detection and management in resource-limited settings. Full article

Background/Objectives: Type 2 diabetes mellitus (T2DM) is a major global public health challenge with a significant impact on human life. The current study aims to provide a comprehensive analysis of the magnitude of dyslipidemia and the factors associated with elevated LDL-C levels among Black South Africans with T2DM. Methods: This was a cross-sectional study conducted in a tertiary hospital. Blood samples for glycated hemoglobin (HbA1c) and lipid profile were collected from the study participants and analyzed using Siemens Atellica™ analyzer. The data was entered into Microsoft excel and analyzed using SPSS version 24. Bivariate and multivariate logistic regression was employed to identify variables significantly associated with the outcomes, with a p-value  ≤  0.05 and a 95% confidence interval. Results: A total of 194 study participants with T2DM were recruited in the study. The overall prevalence of dyslipidemia was 90.72%. Of those with dyslipidemia, 40.9% had an isolated dyslipidemia, 39.7% had a combined dyslipidemia and 19.3% had atherogenic dyslipidemia. Significant factors associated with elevated levels of LDL-C included age, non-adherence to treatment (NAT) and duration. However, after multivariate analysis, NAT was found to be an independent associated factor with elevated levels of LDL-C (AOR: 4.596; 95% CI: 0.177–2.874; p = 0.027). Conclusions: Our study found that dyslipidemia is highly prevalent among Black South African patients with T2DM at a tertiary hospital, despite the use of lipid-lowering therapy. NAT was significantly associated with elevated levels of LDL-C. However, it is important to note that the study employed a cross-sectional design, conducted at a single hospital, which may impair the generalizability of the findings. Full article

Obesity has become a major global health concern, but few studies have examined the determinants of body mass index (BMI, kg/m2) and overweight/obesity (BMI ≥ 25) specifically in women. This study investigated the roles of education, lifestyle, and personality using data from a questionnaire survey of 4276 Japanese adults (2215 women and 2061 men) aged 30–79 years. Multiple regression and logistic regression analyses were conducted to identify factors associated with BMI (continuous) and obesity (BMI ≥ 25) in women. The multiple regression results indicated that educational attainment, rest, diet, and conscientiousness were negatively associated with BMI, whereas extraversion and openness were positively associated with BMI. Logistic regression further showed that higher education, regular exercise, sufficient rest, and conscientiousness were associated with non-obesity (BMI < 25), while openness was associated with obesity (BMI ≥ 25). To our knowledge, this is the first study to identify determinants of BMI and obesity in women with a simultaneous focus on education, lifestyle, and personality traits. Full article

Metabolic syndrome (MetS) is a global public health challenge, characterized by the coexistence of cardiometabolic risk factors such as abdominal obesity, dyslipidaemia, hypertension, and insulin resistance. Non-pharmacological strategies, including the Mediterranean diet (MD) and physical activity (PA), have been widely studied for their potential to prevent and manage MetS. This systematic review aimed to synthesize the evidence on the combined effect of MD and PA on MetS components in adults, based on randomized controlled trials (RCTs). Twenty-two RCTs published between 2018 and 2024 were included, involving 11,478 participants. The interventions ranged from 8 weeks to 3 years and combined adapted or hypocaloric MDs with moderate-to-high-intensity PA, typically including walking, aerobic exercise, or high-intensity interval training (HIIT), performed 3 to 7 times per week. The combined interventions resulted in reductions in body weight (−2.5 to −7.2 kg), body mass index (−0.7 to −2.2 kg/m2), waist circumference (−5.1 to −7.8 cm), and blood pressure (up to −9.0 mmHg systolic and −6.7 mmHg diastolic). Improvements in HDL cholesterol, triglyceride levels, and insulin sensitivity were also observed. These findings suggest that integrated interventions based on the Mediterranean lifestyle are effective in reducing MetS components and may support future public health strategies. Full article

Obesity is a chronic, multifactorial disease characterized by excess body fat and is a major risk factor for various metabolic disorders. Bioactive compounds from the diet have been recognized for their role in preventing chronic non-communicable diseases and as adjuvants in managing endocrine–metabolic dysfunctions. Hibiscus sabdariffa L. (HSL) is rich in bioactive compounds with antioxidant, antihypertensive, and antihyperlipidemic properties. This study evaluated the effects of HSL flower extract supplementation on body composition, lipid profile, and biochemical parameters in both eutrophic and high-fat diet-induced obese rats. Thirty-two Wistar rats were assigned to four groups: control, control plus HSL extract, high-fat diet, and high-fat diet plus HSL extract. The extract was administered orally at 150 mg kg−1 for thirty days. Dual-energy X-ray absorptiometry revealed that HSL supplementation significantly attenuated fat mass gain (from 98 g to 75 g) and adiposity indices (10.23 to 8.86) in obese rats without altering total body mass. Moreover, the HSL extract improved lipid profiles by reducing LDL cholesterol from 23 to 13 mg dL−1 and exhibited potential hepatoprotective effects linked with decreased ALT (40 to 26.7 U L−1) and total bilirubin (0.12 to 0.07 mg dL−1) levels. Although glucose metabolism parameters had no significant differences, a trend toward improved insulin sensitivity was observed. These results suggest that the aqueous HSL extract may exert cardioprotective, hepatoprotective, and anti-obesity effects, supporting its potential as a complementary therapeutic agent in obesity and related metabolic disorders.
