In hypocaloric regimen, latter seems not crucial, whereas at higher calorie intake, ratio and, theoretically, ketosis, may become important. could positively for their very low content, whether ketosis plays an additional role unknown.

The Very Low-Energy Ketogenic Therapy (VLEKT) is a structured, multi-phase dietary regimen characterized by carbohydrate intake of less than 50 g/day and daily caloric fewer 800 kcal, which induces ketosis facilitates significant weight loss. Evidence suggests that this nutritional therapy can improve glycemic control, lipid profiles, blood pressure, making it promising option for managing type 2 diabetes (T2D) reducing cardiovascular risk. These benefits are achieved through reductions in triglycerides low-density lipoprotein cholesterol (LDL-c), alongside increases high-density (HDL-c). However, the effects VLEKT on metabolism remain controversial. review emphasizes urgent need further research to validate long-term safety efficacy VLEKT. It also highlights critical role personalized plans, supervised healthcare professionals, optimize health outcomes address individual patient needs.

Summary First identified as a feasible treatment for intractable epilepsy, the ketogenic diet (KD) has recently gained popularity thanks to growing evidence on applications such weight loss, most importantly, but also NAFLD, cancer, neurologic conditions and chronic pain. As with any treatment, whether pharmacologic or not, KD might not be an appropriate intervention every individual, number of contraindications have been proposed, now deeply rooted into clinical practice, excluding de facto many patients that could benefit from its use. However, these concerns were expressed due absence studies conducted fragile populations, assessment lately emerged relative safety is currently lacking much needed. We herein provide critical revision literature behind each alert, in order guide through options case subjects indication borderline safe situation. Based available evidence, possible use this therapeutic should assessed patient‐to‐patient basis by adequately skilled medical doctors, keeping mind current recommendations, reading them knowledge state art.
