This study aimed to examine the effects of four weeks of a low-carbohydrate diet (LC) and incorporated exercise training on body composition and cardiometabolic health. Fifty-eight overweight/obese Chinese females (age: 21.2 ± 3.3 years, body mass index (BMI): 25.1 ± 2.8 kg/m2) were randomly assigned to the control group (CON, n = 15), the LC control group (LC-CON, n = 15), the LC and high-intensity interval training group (LC-HIIT, n = 15), or the LC and moderate-intensity continuous training group (LC-MICT, n = 13). Subjects consumed a four week LC, whereas LC-HIIT and LC-MICT received extra training 5 d/week (LC-HIIT: 10 × 6 s cycling interspersed with 9 s rest, MICT: 30 min continuous cycling at 50–60% VO2peak). After intervention, the three LC groups demonstrated significant reductions in body weight (−2.85 kg in LC-CON, −2.85 kg in LC-HIIT, −2.56 kg in LC-MICT, p < 0.001, η2 = 0.510), BMI (p < 0.001, η2 = 0.504) and waist-to-hip ratio (p < 0.001, η2 = 0.523). Groups with extra training (i.e., LC-HIIT and LC-MICT) improved VO2peak by 14.8 and 17.3%, respectively. However, fasting glucose and blood lipid levels remained unchanged in all groups. Short-term LC is a useful approach to improve body composition in overweight/obese Chinese females. Incorporated exercise training has no additional effects on weight loss, but has additional benefits on cardiorespiratory fitness, and HIIT is more time efficient than the traditional MICT (2.5 min vs. 30 min).

Objective: The purpose of this study was to evaluate the effects of a 4-week low-carbohydrate diet (LC) with or without exercise training on cardiometabolic health-related profiles in overweight/obese women. Methods: Fifty overweight/obese Chinese women (age: 22.2 ± 3.3 years, body mass index (BMI): 25.1 ± 3.1 kg·m−2) were randomized to either a LC control group (LC-CON, n = 16), a LC and high-intensity interval training group (LC-HIIT, n = 17), or a LC and moderate-intensity continuous training group (LC-MICT, n = 17). All groups consumed LC for 4 weeks, while the LC-HIIT and LC-MICT groups followed an additional five sessions of HIIT (10 × 6 s cycling sprints and 9 s rest intervals, 2.5 min in total) or MICT (cycling continuously at 50–60% of peak oxygen uptake (VO2peak) for 30 min) weekly. Blood pressure, fasting glucose, insulin sensitivity, and several metabolic or appetite regulating hormones were measured before and after intervention. Results: Significant reductions in body weight (− ~2.5 kg, p < 0.001, η2 = 0.772) and BMI (− ~1 unit, p < 0.001, η2 = 0.782) were found in all groups. Systolic blood pressure was reduced by 5–6 mmHg (p < 0.001, η2 = 0.370); fasting insulin, leptin, and ghrelin levels were also significantly decreased (p < 0.05), while insulin sensitivity was improved. However, there were no significant changes in fasting glucose, glucagon, and gastric inhibitory peptide levels. Furthermore, no group differences were found among the three groups, suggesting that extra training (i.e., LC-HIIT and LC-MICT) failed to trigger additional effects on these cardiometabolic profiles. Conclusions: The short-term carbohydrate restriction diet caused significant weight loss and improved blood pressure and insulin sensitivity in the overweight/obese women, although the combination with exercise training had no additional benefits on the examined cardiometabolic profiles. Moreover, the long-term safety and effectiveness of LC needs further study.

Purpose: To determine whether exercise training might exert anti-inflammatory effect by reducing HMGB1 levels in women with breast cancer (BC). Methods: We analyzed monocentric data from the DIANA (DIET AND ANDROGENS)-5 PROJECT. Study population consisted of 94 patients randomized into two groups: 61 patients (53±8 yrs, training group) were assigned to a structured exercise training intervention (3 times/week for the first 3 months, and once /week for the following 9 months); whereas 33 patients (52±7 yrs, control group) followed only the general indications to adhere to the life-style intervention suggestions of the DIANA protocol. At study entry and after 12 months, all patients underwent cardiopulmonary exercise testing, biochemical assessment [HMGB1, high-sensitivity C-reactive protein (hs- CRP), interleukin-6 (IL-6)]; and lipid and glycemic profile. Results: There were no significant differences between groups in baseline clinical and inflammatory profile. Among the training group, only 19/61 patients had high adherence to the exercise intervention. After stratifying the study population according to the level of adhesion to the exercise intervention, 1-year HMGB1 levels were lower among patients more adherent to exercise (p for trend=0.001). Further adjusting for age, body mass index and baseline values, 1-year HMGB1 levels remained significantly and inversely associated to the level of adhesion to the exercise intervention (B=-0.97, SE=0.43, p=0.01). Conclusions: Moderate intensity exercise training in BC survivors is associated with reduced HMGB1 levels that are proportional to the level of adhesion to the exercise intervention, independently from other classical inflammatory molecules, suggesting an exercise-induced anti-inflammatory effect mediated by HMGB1.

CONTEXT AND OBJECTIVE: Changes in metabolism have been reported in the majority of patients undergoing cancer treatment, and these are usually characterized by progressive change in body composition. The effects of aerobic exercise programs to combat the cancer and cancer treatment-related side effects, which include the negative changes in body composition, have been extensively reported in the literature. However, few resistance exercise intervention studies have hypothesized that breast cancer patients might benefit from this type of exercise. The purpose of this study was to determine whether exercise protocols that emphasize resistance training would change body composition and strength in breast cancer patients undergoing treatment. DESIGN AND SETTING: Randomized controlled trial, at the Campus Recreation Center and Rocky Mountain Cancer Rehabilitation Institute of the University of Northern Colorado, and the North Colorado Medical Center. METHODS: Twenty inactive breast cancer patients were randomly assigned to a 21-week exercise group (n = 10) or a control group (n = 10). The exercise group trained at low to moderate intensity for 60 minutes on two days/week. The primary outcome measurements included body composition (skinfold method) and muscle strength (one repetition maximum). RESULTS: Significant differences in lean body mass, body fat and strength (p = 0.004, p = 0.004, p = 0.025, respectively) were observed between the groups at the end of the study. CONCLUSION: The results suggest that exercise emphasizing resistance training promotes positive changes in body composition and strength in breast cancer patients undergoing treatment.

OBJECTIVE: To evaluate the effect of weight and body composition changes on waist measurement of severely obese women receiving a low-carbohydrate diet for a short-term. METHODS: Nineteen severely obese women divided into an intervention and a control group received a low-carbohydrate diet and a conventional diet, respectively, both with 1,200kcal, for seven days. Anthropometric measurements such as weight, body mass index, arm circumference, waist circumference (at the navel), two proposed measurements of waist circumference (waist circumference 1, 10cm above the navel; and waist circumference 2, 20cm above the navel), hip circumference; and body composition (lean mass and fat mass) were performed at baseline and end of the study. RESULTS: There was significant reduction of all variables in the intervention group (p<0.01), but the control group had no change in waist circumference (p=0.06) and hip circumference (p=0.36). Patients of the intervention group presented greater weight loss (4.4kg, p<0.01) and reduction of body mass index, waist circumference, waist circumference 1, waist circumference 2 (p<0.01), and fat mass (p=0.04) than the control group. CONCLUSION: The weight loss and body composition changes were greater in the low-carbohydrate group than in the conventional-diet group, and they had a greater impact on waist measurements. The proposed measurements (waist circumference 1 and waist circumference 2) were sensitive to weight reduction in both groups.

The randomized trials showed that the addition of training resistance program to androgen-deprivation therapy (ADT) had many beneficial effects for prostate cancer (PC) patients (significant protective effect on the volume of muscle mass) and the studies have revealed a panel of miRNAs, which are deregulate in PC and may serve as promising biomarkers of PC risk. The primary aim of our present study was to investigate the effect of exercise training to changes in body composition (muscle strength) and the secondary endpoint was to investigate the impact of an exercise training program on plasma levels of selected myogenic microRNAs (miRNAs) (miRNA-1, miRNA-29b, and miRNA-133) in PC patients undergoing the ADT. Effect of ADT and exercise intervention showed significant increase (experimental group vs. control group) the changes in body composition, free testosterone levels, IL-6 and plasma levels of myogenic miRNAs and significant reduced insulin serum levels. In conclusion, resistance training with ADT in the treatment of PC significantly changed the physical and metabolic function and the plasma levels of specific myogenic miRNAs. Our data support with the other publicized results.

IntroductionTreatment using sodium-glucose cotransporter (SGLT) 2 inhibitor and low-carbohydrate diet (LCD) for obesity and type 2 diabetes are similar in terms of carbohydrate limitation. However, their mechanisms of action differ, and the effects on the body remain unclear. We investigated the effects of SGLT2 inhibitor and LCD on body composition and metabolic profile using the db/db mouse model for obesity and type 2 diabetes.Research design and methodsEight-week-old male db/db mice were divided into four groups: mice receiving normal diet and vehicle or canagliflozin (Cana) administration and mice receiving LCD and vehicle or Cana administration for 8 weeks. Consumed calories were adjusted to be equal among the groups.ResultsBoth Cana administration and LCD feeding resulted in significant weight gain. Cana administration significantly decreased plasma glucose levels and increased plasma insulin levels with preservation of pancreatic β cells. However, LCD feeding did not improve plasma glucose levels but deteriorated insulin sensitivity. LCD feeding significantly reduced liver weight and hepatic triglyceride content; these effects were not observed with Cana administration. Combined treatment with LCD did not lead to an additive increase in blood β-ketone levels.ConclusionsSGLT2 inhibitors and LCD exert differential effects on the body. Their combined use may achieve better metabolic improvements in obesity and type 2 diabetes.

Aim. To investigate the effects of weight loss during an 8-week very low carbohydrate diet (VLCD) on improvement of metabolic parameters, adipose distribution and body composition, and insulin resistance and sensitivity in Chinese obese subjects.Methods. Fifty-three healthy obese volunteers were given an 8-week VLCD. The outcomes were changes in anthropometry, body composition, metabolic profile, abdominal fat distribution, liver fat percent (LFP), and insulin resistance and sensitivity.Results. A total of 46 (86.8%) obese subjects completed the study. The VLCD caused a weight loss of−8.7±0.6 kg (mean ± standard error (SE),P<0.0001) combined with a significant improvement of metabolic profile. In both male and female, nonesterified fatty acid (NEFA) significantly decreased (−166.2±47.6 μmol/L,P=0.001) andβ-hydroxybutyric acid (BHA) increased (0.15±0.06 mmol/L,P=0.004) after eight weeks of VLCD intervention. The significant reductions in subcutaneous fat area (SFA), visceral fat area (VFA), and LFP were−66.5±7.9 cm2,−35.3±3.9 cm2, and−16.4±2.4%, respectively (allPvaluesP<0.0001). HOMA IR and HOMAβsignificantly decreased while whole body insulin sensitivity index (WBISI) increased (allPvaluesP<0.001).Conclusion. Eight weeks of VLCD was an effective intervention in obese subjects. These beneficial effects may be associated with enhanced hepatic and whole-body lipolysis and oxidation.

Background: The increasing prevalence of overweight and related diseases has gained more scientific attention. Overweight and obesity are known as a threat to health, and low serum 25-hydroxy vitamin D levels is associated with obesity. Objectives: Therefore, we examined the effect of Pilates training on body composition, lipid profile, and serum 25-hydroxy vitamin D levels in inactive overweight women. Methods: In this clinical study, 28 overweight women were randomly divided into a training group (n = 14) and a control group (n = 14). Pilates training was performed three 60-min sessions during 12 weeks. In two stages, blood samples were collected 48 hours before and after the last protocol exercise training session. During the 12 weeks, the control group had no exercise training. For analyzing within- and between-group changes, paired t-test and ANCOVA with the significant level of P < 0.05 were used, respectively. Results: After 12 weeks of Pilates training in the training group compared to the control group, there was a significant decrease in the body mass index (P = 0.005), cholesterol (P = 0.001) and triglyceride (P = 0.001) values, and serum 25-hydroxy vitamin D levels (P = 0.005), while high-density lipoprotein (P = 0.028) increased significantly. However, no significant change was observed in low-density lipoprotein levels (P = 0.435). Conclusions: According to the results, it can be indicated that 12 weeks of Pilates training have improved serum 25-hydroxy vitamin D levels, changed anthropometry, and lipid profile in inactive overweight women.

This study was conducted to investigate the effect of cinnamon in high- and low carbohydrate diets on the physiology of rainbow trout (Oncorhynchus mykiss (16.12±1.33 g). Six experimental diets including control/LCarb (200 g/kg carbohydrate), LCarb-3C (200 g/kg carbohydrate, 30 g/kg cinnamon), LCarb-5C (200g/kg carbohydrate, 50 g/kg cinnamon), HCarb (300 g/kg carbohydrate), HCarb-3C (300 g/kg carbohydrate, 30 g/kg cinnamon), and HCarb-5C (300 g/kg carbohydrate, 50 g/kg cinnamon) were formulated to feed fish for eight weeks. The results showed that fish fed dietary LCarb-3C (72.64 g) and LCarb-5C (73.17 g) had higher weight gain as compared with treatments without cinnamon (P<0.05). Blood performance in LCarb3C (67.10) was significantly higher than the HCarb-3C group (P<0.05). Fish fed dietary LCarb-3C had the best performance so that cinnamon in this group lowered glucose, total cholesterol, and low-density lipoprotein, improved total protein, and highdensity lipoprotein contents. Supplementation of this herb also improved protease and lipase in LCarb-3C and LCarb-5C groups as compared with control. Individuals fed supplemented diets but not HCarb had a higher superoxide dismutase activity when compared with the control group (P<0.05). Generally, cinnamon improved parameters in this study in fish fed a low-carbohydrate diet rather than a high-carbohydrate diet.
