Plain language summary
The prevalence of overweight or obesity in children is increasing due to changes in dietary structure and exercise habits, as determined by the body mass index (BMI) calculated from height and weight. Childhood obesity can cause some clinical complications such as hypertension, nonalcoholic fatty liver disease (NAFLD), and cardiovascular disease. The aim of this study was to examine the effects of probiotics on eight factors in children with overweight or obesity. This study was a systematic review and meta-analysis of four studies with a total of 206 overweight or obesity children. Among them, 105 were in the probiotic group, and 101 were in the placebo group. Results showed that probiotics can improve high- and low-density lipoprotein cholesterol, adiponectin, leptin, and TNF-α in overweight or obese children. The systematic review showed that probiotics work mainly by reshaping disturbed intestinal microbiota, regulating lipid metabolism, reducing inflammation and immune response, playing a positive effect of short-chain fatty acids produced, alleviating oxidative stress and endoplasmic reticulum stress, and inhibiting the growth and reproduction of pathogens in the gut. Authors concluded that probiotics could regulate lipid metabolism and immune response to some degree in children with overweight or obesity.
Abstract
BACKGROUND This paper aimed to examine the effects of probiotics on eight factors in overweight or obese children by meta-analysis, namely, body mass index (BMI), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), adiponectin, leptin and tumor necrosis factor-α (TNF-α) and summarize the mechanisms of action of probiotics based on the existing researches. METHODS Six databases (PubMed, Web of Science, Embase, Cochrane Library, SinoMed and CNKI) were searched until March 2023. Review Manager 5.4 was used for meta-analysis. The data were analysed using weighted mean differences (WMDs) or standardized mean differences (SMDs) under a fixed effect model or random effect model to observe the effects of probiotic administration on the included indicators. RESULTS Four publications with a total of 206 overweight or obesity children were included. According to the meta-analysis, probiotics were able to significantly decrease the levels of HDL-C (MD, 0.06; 95% CI 0.03, 0.09; P = 0.0001), LDL-C (MD, - 0.06; 95% CI - 0.12, - 0.00; P = 0.04), adiponectin (MD, 1.39; 95% CI 1.19, 1.59; P < 0.00001), leptin (MD, - 2.72; 95% CI - 2.9, - 2.54; P < 0.00001) and TNF-α (MD, - 4.91; 95% CI - 7.15, - 2.67; P < 0.0001) compared to those in the placebo group. Still, for BMI, the palcebo group seemed to be better than the probiotic group (MD, 0.85; 95% CI 0.04, 1.66; P = 0.04). TC (MD, - 0.05; 95% CI - 0.12, 0.02; P = 0.14) and TG (MD, - 0.16; 95% CI - 0.36, 0.05; P = 0.14) were not different between two groups. CONCLUSIONS This review drew that probiotics might act as a role in regulating HDL-C, LDL-C, adiponectin, leptin and TNF-α in overweight or obesity children. Additionally, our systematic review yielded that probiotics might regulate lipid metabolism and improve obese associated symptoms by some paths. This meta-analysis has been registered at PROSPERO with ID: CRD42023408359.

Plain language summary
Several systematic reviews and meta-analyses conducted to evaluate the prognosis of coronavirus disease-2019 (COVID-19) in people with diabetes mellitus have reported an approximately two- to three-fold higher risk of mortality from COVID-19 in people with diabetes mellitus compared with those without diabetes mellitus. The aim of this study was to investigate the impact of the COVID-19 pandemic and the state of emergency on the glycaemic control, eating habits, and body composition of people with diabetes mellitus. This study is a retrospective, longitudinal observational study in outpatients with diabetes mellitus. A total of 408 participants were included in this study, including 239 men (58.6%) and 169 women (41.4%). People with type 2 diabetes mellitus were predominant in this study (96.8%). Results show that: - there was a significant increase of the haemoglobin A1c level in people with diabetes mellitus during the COVID-19 pandemic. - there was an increase in the changes in body weight and percent fat (increased) and skeletal muscle masses (decreased). Authors conclude that the COVID-19 pandemic caused a negative impact on the glycaemic control and body composition in people with diabetes mellitus. Furthermore, the increase of body weight and fat mass and the decrease of the skeletal muscle mass during the pandemic were associated with poor glycaemic control, independent of the age and sex, in people with diabetes mellitus.
Abstract
AIMS/INTRODUCTION To evaluate the impact of the COVID-19 pandemic on the glycemic control, eating habits, and body composition of people with diabetes mellitus; to identify the determinants of worsening glycemic control in people with diabetes mellitus. MATERIALS AND METHODS This retrospective, longitudinal observational study was performed in outpatients with diabetes mellitus who visited our hospital between April 2019 and March 2020 (pre-COVID-19 period) and continued for follow up from April 2020 to March 2021 (COVID-19 period). We compared the glycemic control, nutritional intakes, and body composition of people with diabetes mellitus between the two periods. The changes in the HbA1c values (ΔHbA1c) and other study variables were compared between the two periods. Logistic regression analysis was performed to identify the factors associated with the increase of HbA1c levels. RESULTS A significant increase of HbA1c was observed during the COVID-19 period. The percent fat mass (FM) also increased, while the percent skeletal muscle mass (SMM) decreased during the COVID-19 period. After adjustments for age and sex, the ΔBMI (OR:2.33), ΔFM (OR:1.45), and ΔSMM (OR:0.51) were identified as being associated with elevated levels of HbA1c. CONCLUSIONS The COVID-19 pandemic had a negative impact on the glycemic control and body composition of people with diabetes mellitus. The increased body weight and FM and decreased SMM observed during the pandemic were associated with poor glycemic control in people with diabetes mellitus.

Plain language summary
Excessive gestational weight gain exposes the woman and the child to a higher risk of harmful health outcomes in the short and long term. Dietary patterns based on the substitution of meals made with unprocessed or minimally processed foods for the consumption of ultra-processed items can be partly blamed for the exponential global growth in the incidence of obesity. The main aim of this study was to evaluate the effectiveness of a nutritional intervention based on encouraging the consumption of unprocessed and minimally processed foods rather than ultra-processed products. This study is a two-armed parallel randomised controlled trial conducted among overweight, pregnant women receiving prenatal care in seven primary health units. Participants (n=350) were randomly allocated into the intervention group (IG) or control group (CG). The women allocated into the IG, in addition to the usual prenatal care, were invited to participate in three individualised nutritional counselling sessions conducted by trained nutritionists. Results show that even though there were more women in the IG who had increased their daily intake of minimally processed foods and vegetables at lunch time when compared to the CG, this was not statistically significant. Additionally, there weren’t any differences between the groups in relation to physical activity. Authors conclude that their study was unprecedented in demonstrating that a nutritional counselling intervention based on the NOVA food classification system, together with the practice of physical activity, is effective in preventing excessive gestational weight gain in overweight pregnant women.
Abstract
PURPOSE This study aimed at evaluating the effectiveness of a nutritional counselling intervention based on encouraging the consumption of unprocessed and minimally processed foods, rather than ultra-processed products, and the practice of physical activities to prevent excessive gestational weight gain in overweight pregnant women. METHODS This was a two-armed, parallel, randomized controlled trial conducted in primary health units of a Brazilian municipality from 2018 to 2021. Overweight, adult pregnant women (n = 350) were randomly assigned to control (CG) or intervention groups (IG). The intervention consisted of three individualized nutritional counselling sessions based on encouraging the consumption of unprocessed and minimally processed foods rather than ultra-processed products, following the NOVA food classification system, and the practice of physical activities. The primary outcome was the proportion of women whose weekly gestational weight gain (GWG) exceeded the Institute of Medicine guidelines. Adjusted logistic regression models were employed. RESULTS Complete data on weight gain were available for 121 women of the IG and 139 of the CG. In modified intention-to-treat analysis, there was a lower chance of the IG women having excessive GWG [OR 0.56 (95% CI 0.32, 0.98), p = .04], when compared to the CG. No between-group differences were observed for the other maternal outcomes investigated. CONCLUSION The present study was unprecedented in demonstrating that nutritional counselling based on the NOVA food classification system, together with encouraging the practice of physical activity, is effective in preventing excessive weight gain in overweight pregnant women.

Plain language summary
Malnutrition, which is commonly observed among older adults, is strongly associated with altered body composition, diminished physical and mental function as well as other adverse clinical outcomes. The aim of this study was to investigate the effects of intense nutritional therapy, including free access to energy- and protein-dense foods delivered to subjects recently discharged from hospital. This study is a 6-month, randomised controlled, assessor blinded intervention trial conducted in older adults. The participants (n=106) were randomly allocated to either the intervention or the control group. Results show that the nutrition intervention: - had strong beneficial effects on body weight (moderate weight gain in the intervention group compared to weight loss in the control group) and other anthropometric measures; - had favourable effects on physical function (however, there were no changes in muscular strength), and - led to improved nutritional status after being discharged from hospital (whereas the dietary intake decreased dramatically in the control group despite being informed at discharge of the importance of nutrition). Authors conclude that a 6-month nutrition therapy provided by a clinical nutritionist, following the principles of Nutrition Care Process in combination with freely delivered supplemental energy- and protein-dense foods, has beneficial effects on body weight, physical function, dietary intake, and nutritional status.
Abstract
BACKGROUND/OBJECTIVES Malnutrition is common among older adults. Dietary intervention studies in older adults aiming to improve anthropometrics measures and physical function have been inconsistent. We aimed to investigate the effects of nutrition therapy in combination with home delivered meals and oral nutritional supplements (ONS) in community-dwelling older adults discharged from hospital. METHODS A total of 106 participants (>65 years) were randomized into the intervention group (n = 53) and into the control group (n = 53). The intervention group received individual nutrition therapy (five in person visits and three phone calls) and freely delivered energy- and protein- rich foods, while the control group received standard care. Dietary intake, anthropometrics, and short physical performance battery (SPPB) were assessed at baseline and at endpoint. RESULTS Energy intake at baseline was similar in both groups (~1500 kcal at the hospital) but there was a significant increase in energy intake and body weight in the intervention group (+919 kcal/day and 1.7 kg, P < 0.001 in both cases) during the study period, compared to a significant decrease in both measures among controls (-815 kcal/day and -3.5 kg, P < 0.001 in both cases). SPPB score increased significantly in the intervention group while no changes were observed among controls. CONCLUSIONS Most Icelandic older adults experience substantial weight loss after hospital discharge when receiving current standard care. However, a 6-month multi-component nutrition therapy, provided by a clinical nutritionist in combination with freely delivered supplemental energy- and protein-dense foods has beneficial effects on body weight, physical function, and nutritional status.

Plain language summary
Intermittent fasting (IF) involves an alternation of abstinence and consumption of food and caloric beverages over a cycle of hours to days. Time-restricted feeding (in animals) or eating (TRE in humans) is a form of IF that entails restricting eating within a window of 4 to 12 hours per 24-hour cycle and prolonging the time spent in the fasted state to realign eating-fasting patterns with circadian rhythms. The aim of this study was to explore the impact of a 6-month randomised controlled trial of TRE versus standard dietary advice (SDA, active control arm) on bone metabolism and health in a population with at least one component of the metabolic syndrome. This study is a secondary analysis of an open-label 6-month randomised controlled trial in which participants who ate within a time interval > 14 hours per 24-hour cycle (n=54) were randomised to TRE or SDA (active control) with a 1:1 allocation ratio. A total of 42 participants (76% women) with available bone turnover markers and/or bone mass measurements were included in this study. Results show that there weren’t any detrimental effects on bone health outcomes i.e. bone metabolism or bone loss after 6 months of TRE. Additionally, weight loss following a period of TRE might be associated with small bone-sparing effects compared with SDA. Authors conclude that future studies of longer duration (>6 months) assessing multiple bone phenotypes are required in order to confirm the study’s findings and explore the effects of various TRE regimens particularly among individuals at risk for bone fragility such as postmenopausal women and the elderly.
Abstract
OBJECTIVE This study explored the impact of time-restricted eating (TRE) versus standard dietary advice (SDA) on bone health. METHODS Adults with ≥1 component of metabolic syndrome were randomized to TRE (ad libitum eating within 12 hours) or SDA (food pyramid brochure). Bone turnover markers and bone mineral content/density by dual energy x-ray absorptiometry were assessed at baseline and 6-month follow-up. Statistical analyses were performed in the total population and by weight loss response. RESULTS In the total population (n = 42, 76% women, median age 47 years [IQR: 31-52]), there were no between-group differences (TRE vs. SDA) in any bone parameter. Among weight loss responders (≥0.6 kg weight loss), the bone resorption marker β-carboxyterminal telopeptide of type I collagen tended to decrease after TRE but increase after SDA (between-group differences p = 0.041), whereas changes in the bone formation marker procollagen type I N-propeptide did not differ between groups. Total body bone mineral content decreased after SDA (p = 0.028) but remained unchanged after TRE (p = 0.31) in weight loss responders (between-group differences p = 0.028). Among nonresponders (<0.6 kg weight loss), there were no between-group differences in bone outcomes. CONCLUSIONS TRE had no detrimental impact on bone health, whereas, when weight loss occurred, it was associated with some bone-sparing effects compared with SDA.

Plain language summary
The main factors that contribute to obesity are genetics, excessive energy intake, decreased physical activity, and sedentarism. Sleep duration, sleep timing and chronotype have also recently been recognised as possible risk factors for obesity in children. The aim of this study was to assess the effectiveness of an intervention (usual care vs. intervention group) on sleep quality and its relationship with changes in biochemical and metabolic syndrome related anthropometric parameters. This study was a randomised controlled trial. The multidisciplinary intervention consisted of a two-year program that comprised a 2-month intensive phase with individual and group sessions and a follow-up period at 12 and 24 months. Subjects were randomly assigned to the usual care or intervention group at a ratio of 1:3. Results showed that a lifestyle intervention improved most sleep parameters in children and adolescents with abdominal obesity. In fact, the lifestyle intervention showed a reduction in anthropometric indexes and several biochemical parameters, and improved sleep quality at 2, 12, and 24 months of follow-up. Decreasing sleep latency, awakenings duration and wakefulness after sleep onset (WASO) also accompanied improved sleep efficiency. Authors conclude that their findings add to the growing body of research on the relationship between sleep and metabolic health outcomes in children, emphasizing the need to consider multiple dimensions of sleep beyond just sleep duration.
Abstract
BACKGROUND/OBJECTIVE childhood obesity and sleep disorders have a well-established cross-sectional association, but lifestyle interventions' effects on sleep quality remain under-researched. This study aimed to evaluate the sleep quality of 122 participants (7-16 years) with abdominal obesity after a 2-year necessary lifestyle intervention. PATIENTS/METHODS participants were assigned to either the intervention group (moderate hypocaloric Mediterranean Diet) or the usual care group (standard recommendations on a healthy diet). Sleep was objectively assessed using triaxial accelerometry, and sleep parameters analyzed included latency, efficiency, wake after sleep onset, total time in bed, total sleep time, number of awakenings, and awakening duration. RESULTS AND CONCLUSIONS the results showed that the intervention group significantly improved sleep latency at 12 and 24 months and improved sleep efficiency at 2 and 12 months, compared to the usual care group. Wake after sleep onset and the number of awakenings were significantly reduced at 24 months in the intervention group. Wake after sleep onset and leptin levels were positively associated in all participants. Total time in bed was inversely associated with triglycerides and metabolic score, and total sleep time was inversely associated with leptin, triglycerides, and metabolic score after the 2-month intervention. Triglyceride levels were inversely associated with total time in bed and total sleep time at one year, while the metabolic score was directly associated with wake after sleep onset and the number of awakenings and inversely associated with efficiency. In conclusion, the multidisciplinary intervention in children and adolescents with abdominal obesity reduced anthropometric parameters and improved sleep habits.

Globally, excess weight (overweight or obesity) in childhood represents a major public health threat, especially in Europe. Among healthy dietary patterns, the Mediterranean diet (MedDiet) has been recognised worldwide due to its distinctive health benefits. The aim of this study was to evaluate the effects of MedDiet-based interventions on anthropometric and obesity indicators among children and adolescents. This study was a systematic review and meta-analysis of fifteen randomised controlled trials. The studies included a total of 7184 participants (intervention groups: n = 3356) aged between 3 and 18 years. Results showed that the MedDiet-based interventions in a trial setting can be safely conducted in children and adolescents. In fact, the MedDiet-based interventions decreased body mass index and the percentage of obesity in children and adolescents. Authors conclude that their findings highlight the efficacy of MedDiet-based interventions as a useful tool in reversing the high prevalence of obesity.
Abstract
To our knowledge, no systematic review with meta-analysis has separately synthesized the effects of Mediterranean diet-based interventions in children and adolescents in relation to the effects on anthropometric measures. A better understanding of the effects of Mediterranean diet-based interventions on anthropometric variables could facilitate their implementation in efforts to prevent obesity in the young population. The aim of the present meta-analysis was to evaluate the effects of Mediterranean diet-based interventions on anthropometric and obesity indicators among children and adolescents. Four databases were systematically searched (PubMed, Scopus, Web of Science, and Cochrane Database of Systematic Reviews), including all studies up until 15 March, 2023. Eligible articles were randomized controlled trials measuring the effect of an intervention based on the promotion of the Mediterranean diet and obesity-associated parameters. The effect size of each study was estimated by Cohen's d for continuous variables or risk difference for categorical variables. Compared to the control group, the Mediterranean diet-based interventions showed small and significant reductions in body mass index (d = -0.14; 95% CI: -0.26, -0.01; I2 = 77.52%). Participants in the Mediterranean diet-based interventions had a significant reduction in the percentage of obesity (risk difference = 0.12; 95% CI: 0.01, 0.23; I2 = 84.56%) in comparison with the control group. Interventions had greater effects when aiming at participants with excess weight (that is, overweight or obesity), both for body mass index, waist circumference, waist-to-height ratio, percentage of obesity, and percentage of abdominal obesity. Mediterranean diet-based interventions have a significant effect on reducing the body mass index as well as reducing obesity in children and adolescents (aged 3-18 y). This trial was registered at PROSPERO as CRD42023386789.

Overweight and obesity can be attributed to a complex interplay of multiple factors that result in a dysregulated energy balance in the body, leading to an abnormal accumulation of adipose tissue or body fat. The aim of this study was to evaluate the impact of a specific multispecies synbiotic supplement, containing a blend of seven probiotic strains and fructooligosaccharides, on body composition, antioxidant levels, and gut microbiome composition in overweight and obese individuals. This study was a double-blind, placebo-controlled, randomised, parallel design study. Participants were randomly assigned to either a placebo (n = 36) or synbiotic (n = 36) group based on their age, gender, body weight, and body mass index (BMI). Results showed notable improvement in body composition (waist circumference and body fat percentage), antioxidant status, and gut microbiota in overweight and obese individuals over 12 weeks. However, at the end of the study, there were no significant differences in body weight, body mass index, waist circumference, or percentage of body fat between the synbiotic group and the placebo. Authors conclude that synbiotic consumption may be a viable strategy for promoting overall health in individuals with overweight or obesity. However, further research is needed to determine its long-term effects.
Abstract
Studies investigating the effect of multispecies synbiotic supplementation in obesity management are limited. The current study was performed to evaluate the effects of multispecies probiotics mixed with fructooligosaccharides on body composition, antioxidant status, and gut microbiome composition in overweight and obese individuals. We employed a randomized, double-blind, placebo-controlled trial design, in which 63 individuals aged 18-45 years were assigned to receive either a synbiotic supplement or placebo for 12 weeks. The synbiotic group consumed a daily dose of 37 × 109 colony-forming units (CFU) of a unique blend of seven different probiotics, along with 2 g of fructooligosaccharides, while the placebo group consumed 2 g of maltodextrin daily. Assessments were performed at baseline, week 6, and the end of the study. The results of the study indicated that synbiotic supplementation resulted in a significant reduction in waist circumference and body fat percentage compared to the baseline measurements, as observed at 12 weeks. At the end of the study, there were no significant differences observed in body weight, BMI, waist circumference, or percentage of body fat between the synbiotic group and the placebo group. An analysis of plasma antioxidant capacity revealed that synbiotic supplementation caused a significant increase in Trolox equivalent antioxidant capacity (TEAC) and a concomitant decrease in malondialdehyde (MDA) in the test group when compared to the placebo. For the gut microbiota analysis, synbiotic supplementation significantly decreased Firmicutes abundance and the Firmicutes/Bacteroidetes (F/B) ratio at week 12 as compared to the placebo group. Nevertheless, the synbiotic group did not exhibit any substantial alterations in other biochemical blood parameters compared to the placebo group. These findings suggest that multispecies synbiotic supplementation could be a beneficial strategy to improve body composition, antioxidant status, and gut microbiome composition in overweight and obese subjects.

Gut microbiota is defined by all the beneficial microorganisms that live and grow in the intestine. It is set up from birth and evolves according to different factors. Today, the microbiota is considered a therapeutic revolution, where researchers use its enrichment to prevent or treat certain diseases including obesity. The aim of this study was to evaluate the effects of a probiotic supplement containing Bifidobacteruim, Lactobacillus strains and a prebiotic supplement by carob on the changes in body composition and metabolic biomarkers in subjects with obesity. This study was a prospective interventional study. Forty-five patients were recruited on their first visit to the obesity unit and were randomly assigned to three groups. All participants were enrolled in the weight loss program at the beginning of the study and followed a low-carbohydrate, reduced-energy intake eating plan. Results showed that a low-carbohydrate, restricted-energy diet effectively showed positive results in terms of weight loss, metabolic parameters and obesity-related psychiatric disorders in obese individuals. Authors concluded that prebiotics and probiotics supplementation with lifestyle measures can be taken into consideration for the management of obesity.
Abstract
INTRODUCTION The management of obesity is difficult with many failures of lifestyle measures, hence the need to broaden the range of treatments prescribed. The aim of our work was to study the influence of pre and probiotics on weight loss psychological profile and metabolic parameters in obese patients. METHODS It is a clinical trial involving 45 obese patients, recruited from the Obesity Unit of the National Institute of Nutrition between March and August 2022 divided into three groups: diet only (low-carbohydrate and reduced energy diet), prebiotics (30 g of carob/day) and probiotics (one tablet containing Bifidobacterium longum, Lactobacillus helveticus, Lactococcus lactis, Streptococcus thermophilus/day). The three groups were matched for age, sex and BMI. Patients were seen after 1 month from the intervention. Anthropometric measures, biological parameters, dietary survey and psychological scores were performed. RESULTS The average age of our population was 48.73 ± 7.7 years, with a female predominance. All three groups showed a significant decrease in weight, BMI and waist circumference with p < .05. Only the prebiotic and probiotic group showed a significant decrease in fat mass (p = .001) and a significant increase in muscle strength with p = .008 and .004, but the differences were not significant between the three groups. Our results showed also a significant decrease in insulinemia and HOMA-IR in the prebiotic group compared to the diet-alone group (p = .03; p = .012) and the probiotic group showed a significant decrease in fasting blood glucose compared to the diet alone group (p = .02). A significant improvement in sleep quality was noted in the prebiotic group (p = .02), with a significant decrease in depression, anxiety and stress in all three groups. CONCLUSIONS The prescription of prebiotics and probiotics with the lifestyle measures seems interesting for the management of obesity especially if it is sarcopenic, in addition to the improvement of metabolic parameters and obesity-related psychiatric disorders.
