Summary: This study examined the inter-day reliability of RMR, RER, MFO, and Fatmax in healthy adult males using the Ergostik gas analyzer. The results showed no significant differences in these measures between two consecutive days, indicating good inter-day reliability of the instrument in healthy men.

Summary: Treadmill exercise leads to higher fat oxidation rates and maximal fat oxidation values compared to elliptical and rowing exercises, as well as lower post-exercise blood lactate concentrations.

Summary: VSG surgery can reduce body weight, improve glucose tolerance, and induce unique gene expression changes in the liver, fat, and muscle, but not more significantly than the pair-fed group of sham-operated mice. VSG surgery can induce organ-specific gene expression changes in the liver, fat, and muscle, which may play critical roles in metabolic improvements after VSG.

Summary: The study found that intensified milk replacer feeding has long-term effects on energy metabolism of dairy calves, showing greater efficiency estimates preweaning but not persisting after weaning.

Summary: This study investigates the potential roles and mechanisms of gut metabolites in the anti-obesity effect and metabolic improvement induced by vertical sleeve gastrectomy (VSG). Licoricidin is identified as an anti-obesity metabolite that mediates the crosstalk between the gut and adipose tissue. These findings provide new insights into treatment options for obesity and its associated metabolic diseases.

Summary: The study prospectively assessed the impact of weight loss following laparoscopic sleeve gastrectomy on epicardial fat thickness (EFT) and found a significant reduction in EFT. The analysis showed a notable correlation between EFT and weight, body mass index (BMI), fasting blood glucose, and creatinine.

Summary: Recent research challenges the notion that high carbohydrate, low fat (HCLF) diets are superior for athletic performance and highlights the potential health benefits of low carbohydrate, high fat (LCHF) diets. In this study, highly trained competitive middle-aged athletes followed either a HCLF or LCHF diet for 31 days and found that there were no significant differences in performance, body composition, or metabolic markers between the two groups. However, the LCHF diet resulted in higher rates of fat oxidation and improved glycemic control, especially in individuals at risk for diabetes.

Summary: The study shows that the effects of training on whole-body fat oxidation in young men may be attenuated in middle-aged men. This indicates that the ability to oxidize fat during exercise declines with age, but regular exercise training can help counteract this decline.

Summary: Direct measurements of glucose and insulin in the blood entering and leaving the liver show that VSG affects glucose and insulin metabolism through mechanisms independent of weight loss and diet. Insulin levels were elevated in the portal vein, and hepatic insulin clearance was elevated in VSG-operated mice. Hepatic expression of genes associated with insulin clearance was upregulated.

Summary: Bariatric surgery, specifically sleeve gastrectomy, is effective in reducing body weight and improving metabolic control. This study investigates the protective effect of sleeve gastrectomy on shear stress-induced atherosclerosis in an overweight mouse model with carotid artery ligation.

Summary: Higher dietary fiber intake is associated with increased basal fat oxidation, while higher fat intake is associated with maximal fat oxidation during exercise in sedentary adults. However, these associations are attenuated after considering factors such as sex, age, and energy intake.

Summary: This study found that maximal fat oxidation and the intensity that elicits it remain consistent throughout the day in healthy women, regardless of the time of exercise testing. These results have clinical relevance in understanding the differences between men and women in terms of fat oxidation during exercise.

Summary: This study aimed to provide exercise intensity guidelines and training volume recommendations for maximizing fat oxidation in patients with obesity. It was found that relative heart rate, rather than relative oxygen uptake, should be used for establishing FATmax reference values in these patients. A heart rate of 61-66% HRpeak should be recommended to patients with > 35% body fat, while a heart rate of 57-64% HRpeak should be recommended to patients with body fat < 35%.

Summary: Various factors in the environment, as well as physicochemical characteristics and circulating molecules, can influence erythrocyte deformability. Some influences are reversible physiological changes, while others may lead to red cell death. The clearance of rigid erythrocytes by the spleen plays a major regulatory role. Erythrocyte deformability is under the influence of multiple regulatory loops to meet the oxygen or fuel delivery needs of tissues.
