Aims: To date, bariatric surgery (BS) is the most effective long-term treatment for obesity, but weight regain (WR) is common. The very low-calorie ketogenic diet (VLCKD) is effective for weight loss and may influence gut microbiota (GM) composition, but it has been scarcely evaluated in post-bariatric patients. This study compared the efficacy and safety of a VLCKD in patients with WR post-bariatric surgery (BS+) and in bariatric surgery-naïve patients (BS-).

Background: Inadequate treatment responses, chemotherapy resistance, significant heterogeneity, and lengthy treatment durations create an urgent need for new pancreatic cancer therapies. This study aims to investigate the effectiveness of gemcitabine-loaded nanoparticles enclosed in an organo-metallic framework under ketogenic conditions in inhibiting the growth of MIA-PaCa-2 cells.
Methods: Gemcitabine was encapsulated in Metal-organic frameworks (MOFs) and its morphology and size distribution were examined using transmission electron microscopy (TEM) and Dynamic light scattering (DLS) with further characterization including FTIR analysis.

Epilepsy is a chronic neurological disorder caused by abnormal discharges of neurons in the brain, which seriously affects the quality of life of patients. Although there are various drug treatments available, many epilepsy patients still experience seizures with the effect of drugs and develop refractory epilepsy. The ketogenic diet can treat drug-refractory epilepsy by regulating the body's metabolism and can enhance the quality of life by improving their cognition, behavior, and sleep quality.

Background: Previous studies show that ketosis caused by the consumption of low-carbohydrate diets improves cognitive functions and that ketogenic diets can be used to treat epilepsy. In vivo and in vitro experiments have shown that ketosis regulates pain, inflammation, and oxidative stress. Thus, we investigated the effects of ketosis induced by a low-carbohydrate diet on muscle soreness, inflammation, and redox status in human subjects.

Very-low-carbohydrate diets (LCHF; <50g/day) have been debated for their potential to lower pre-exercise muscle and liver glycogen stores and metabolic efficiency, risking premature fatigue. It is also hypothesized that carbohydrate ingestion during prolonged exercise delays fatigue by increasing carbohydrate oxidation, thereby sparing muscle glycogen. Leveraging a randomized crossover design, we evaluated performance during strenuous time-to-exhaustion (70%⩒O) tests in trained triathletes following 6-week high-carbohydrate (HCLF, 380g/day) or very-low-carbohydrate (LCHF, 40g/day) diets to determine (i) if adoption of the LCHF diet impairs time-to-exhaustion performance, (ii) whether carbohydrate ingestion (10g/hour) 6-12x lower than current CHO fuelling recommendations during low glycogen availability (>15-hour pre-exercise overnight fast and/or LCHF diet) improves time-to-exhaustion by preventing exercise-induced hypoglycemia (EIH; <3.
