Summary: The study showed that following a LCHF diet resulted in higher levels of free fatty acids and ketones, as well as a decreased level of glucose. It also led to an increased cortisol response after exercise, indicating potential effects on metabolism and exercise performance. Additionally, athletes on a LCHF diet experienced reduced workload and increased perceived exertion during exercise compared to a high carbohydrate diet.

Summary: Ketogenic diets and ketone supplements result in different changes in substrate metabolism, with supplements having a stronger ketosis effect. Ketogenic diets increase fat oxidation and accumulate ketone bodies as fuel, while supplements rapidly increase ketone body concentrations and inhibit fatty acid mobilization during aerobic exercise.

Summary: The aim of this study was to assess the effects of an eight-week Paleo diet on the health status and physical capacity of professional handball players. The results showed significant decreases in body weight, body mass index, and fat mass, as well as an increase in fat-free mass in both groups. There were no significant differences in hematological and biochemical indicators between the groups. The Paleo diet had a slight adverse effect on anaerobic capacity, but did not affect aerobic capacity.

Summary: The use of high-fat, ketogenic diets to support physical performance has gained popularity, but the impact of such diets on performance remains controversial. A systematic review of 17 studies found that while ketogenic diets may have varying effects on endurance and power/strength performance, overall they do not significantly improve or impair physical performance compared to mixed macronutrient diets. Various factors such as duration of diet consumption, training status, performance tests, and sex differences may contribute to the conflicting results observed in different studies.

Summary: This study investigated the effect of acute exercise on the inflammatory response in adipose tissue of lean and obese mice. Acute exercise enhanced the levels of IL-6 and tumor necrosis factor-a in the adipose tissue of lean mice, while no changes were observed in proinflammatory cytokines in obese mice. However, the levels of IL-13, IL-4, and IL-10 were increased in obese mice after exercise. These findings suggest that acute exercise promotes an inflammatory response in adipose tissue of lean mice, but elicits an anti-inflammatory response in adipose tissue of obese mice.

Summary: This study evaluated the impact of low-carbohydrate diets after breast cancer diagnosis on breast cancer-specific and all-cause mortality. The results showed that adherence to low-carbohydrate diets, especially plant-rich low-carbohydrate diets, was associated with improved overall survival but not breast cancer-specific survival.

Summary: The present study examined the effects of an isocaloric low-carbohydrate ketogenic diet (LCKD) with or without exercise on postpartum weight retention, body composition, metabolic profile, and physical activity performance in postpartum mice. The results showed that LCKD alone was less effective in reducing postpartum weight retention and had negative effects on metabolic outcomes and physical activity performance.

Summary: The low-carbohydrate ketogenic diet can enhance fatty acid oxidation capacity but does not significantly improve maximal exercise capacity. Training has minimal impact on fatty acid oxidation and carbohydrate utilization. Despite favoring the fatty acid oxidation system, an LCKD, alone or combined with training, does not show beneficial effects in high-intensity exercise.

Summary: Endurance athletes require a regular and detailed nutrition program to prepare for training/racing, endure harsh conditions, and recover effectively. Recent decades have seen an interest in new dietary approaches among endurance athletes, including vegetarian, high-fat, intermittent fasting, gluten-free, and low FODMAP diets. This review provides insights into the impact of these popular diets on endurance performance and athlete health.

Summary: This study demonstrates that in healthy young individuals, consuming a very low-carbohydrate, high-fat diet combined with regular exercise over a 12-week period can lead to reductions in body weight and fat mass, along with beneficial changes in serum adiponectin and leptin concentrations, supporting the use of this dietary strategy for the prevention of chronic diseases associated with systemic low-grade inflammation.

Summary: This study aimed to develop sex and population-specific normative data and cutoff values for the muscle quality index (MQI). Analysis of data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 revealed differences in MQI values by sex and population studied. Men generally had lower MQI values compared to women, and non-Hispanic Asians had higher MQI values while non-Hispanic Blacks had lower values.

Summary: This study evaluated the association between plasma omega-3 (to-3) and appendicular muscle mass index (AMMI) in young and middle-aged individuals. The results showed that total plasma to-3, DHA, EPA, and ALA were not associated with AMMI in both men and women. Additionally, there was no association found between plasma to-3 and AMMI in separate analyses of young and middle-aged individuals.

Summary: Postmenopausal women often have cardiometabolic diseases and higher oxidative stress. Exercise, such as Mat Pilates, can be beneficial, but its physiological effects need further investigation. This study aimed to explore the impact of 12 weeks of Mat Pilates on redox status in postmenopausal women with cardiometabolic diseases. The results showed no significant changes in redox markers between the groups, except for greater reductions in total antioxidant capacity in the SINGLE group.

Summary: This study utilizes pulse wave velocity to diagnose arterial stiffness and systemic blood pressure levels. The carotid-femoral pulse wave velocity and central and peripheral pressures were evaluated in all patients, revealing that 56.7% of the sample had pulse wave velocity higher than 7.6 m/s. Elderly individuals with normal blood pressure may still have a risk of arterial stiffness.

Summary: Carnosine levels play a significant role in buffering intracellular pH during exercise, with beta-alanine availability being the limiting factor for muscle carnosine synthesis. Meta-analysis results show that beta-alanine supplementation has a positive effect on high-intensity exercise performance. Adverse effects of beta-alanine usage are minimal, with only paresthesia reported at high doses, which can be mitigated by splitting doses or using sustained-release formulas. Longer supplementation periods and safety evaluations in representative populations are still needed.
