This 2006 review article examines the efficacy and considerations of Very Low Energy Diets (VLEDs) in obesity treatment. VLEDs provide between 450 and 800 kcal/day, delivering complete nutritional requirements. They induce rapid weight loss, typically 1.5–2.5 kg/week, through mechanisms like mild ketosis, which suppresses hunger and preserves lean body mass.
This 2004 review by Astrup et al. evaluates the efficacy and safety of low-carbohydrate diets, such as the Atkins diet, in weight loss. The authors discuss randomized controlled trials comparing low-carbohydrate diets to low-fat diets, noting that while low-carbohydrate diets may lead to greater weight loss at six months, differences
This 2020 translational review analyzed 22 studies—11 preclinical and 11 clinical—evaluating the impact of ketogenic diets (KDs) and medium-chain triglyceride (MCT) supplementation on Alzheimer’s disease (AD). Animal studies showed consistent improvements in cognitive and motor outcomes, reductions in amyloid and tau pathology, and enhanced mitochondrial function. Human trials, though varied
