[Abstract]
The effects of a ketogenic diet (KD) on anthropometric indices, the lipid profile, and the benefits of the ketone body beta-hydroxybutyrate (BHB) as an inhibitor of the NOD-like receptor pyrin domain-containing 3 (NLRP3) inflammasome in obese women were investigated in this study. From January to March 2021, 23 obese adult women (n = 23) with an average age of 35.30 years and BMI of 33.96 kg/m2 followed a KD. Instructions for the KD were given to eligible participants, with a typical plan and a menu for all the main meals, snacks, and drinks permitted over seven days. They were also free to change meals according to their preferences provided that they followed the plan. The participants attended six times throughout the intervention for measurements of their anthropometric indices, BHB levels, interleukin-1beta (1L-1β) levels, and completion of a questionnaire (pre-intervention, mid-intervention, and post-intervention). Following the KD caused significant weight loss, a reduction in waist circumference and BHB levels, as well as a reduction in BMI and appetite. Cholesterol, triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C) increased slightly. However, low-density lipoprotein cholesterol (LDL-C) in serum increased significantly (p < 0.05), and 1L-1β decreased significantly (p < 0.0001). The results show that the KD effectively encouraged weight loss and NLRP3 inflammasome inhibition. Based on the questionnaire results, it was found that a variety of physical symptoms, including overall energy, physical activity, mood, sleep, focus, skin conditions, and menstruation, had significantly improved.
