In an era where diabetes, prediabetes, and insulin resistance have reached epidemic proportions, How to Reduce Glucose offers a rigorous, evidence-based roadmap for restoring healthy blood sugar regulation through informed dietary choices. Written by registered dietitian and nutrition researcher Jona White, this academic-grade compendium critically evaluates seven major eating patterns low-carbohydrate, ketogenic, Paleolithic, Mediterranean, plant-based, intermittent fasting, and DASH against the gold-standard metrics of glycaemic control, cardiovascular risk, nutritional adequacy, and long-term sustainability. Each chapter dissects peer-reviewed literature, meta-analyses, and landmark clinical trials to quantify effects on weight, HbA1c, insulin sensitivity, lipid profiles, and blood pressure. Rather than championing a single "best" diet, White provides balanced appraisals of biochemical mechanisms, potential micronutrient deficiencies, contraindications for special populations, and practical implementation barriers such as food cost, cultural acceptability, and environmental impact. Guidance on individualization by age, sex, activity level, comorbidities, and ethical preferences is woven throughout, equipping clinicians, researchers, and advanced students to translate data into personalized, sustainable prescriptions. The concluding synthesis distils cross-cutting principles for successful glucose management: prioritize minimally processed, high-fibre foods; match carbohydrate load to metabolic tolerance; monitor biomarkers rigorously; and adjust regimens iteratively with professional oversight. Extensive reference lists and evidence tables transform the volume into a ready literature toolkit for academic coursework, clinical practice, or dissertation design.
