Very-Low-Carbohydrate Diet for Prediabetes and Obesity

Sponsor: Universiti Teknologi Mara

Summary

Prediabetes is a condition where blood sugar is higher than normal but not yet high enough to be called type 2 diabetes. It is common in adults who are overweight or obese, and without treatment it often progresses to diabetes over time. This study looks at whether following a very-low-carbohydrate diet for 12 weeks can help adults with prediabetes and obesity lose weight, reduce body fat, and improve how well their body responds to insulin, compared with standard dietary advice. Adults aged 30 to 65 with obesity and newly diagnosed prediabetes are invited to take part. Participants are randomly assigned to one of two groups: one follows a very-low-carbohydrate diet with support from a dietitian, and the other receives standard dietary advice without a specific carbohydrate limit. Both groups are followed for 12 weeks, during which their weight, body composition, blood sugar, insulin levels, cholesterol, and kidney function are checked. The study aims to find out whether the very-low-carbohydrate diet leads to greater improvements in weight, body fat, and insulin sensitivity than standard advice, and whether it is safe and practical to follow in everyday life. The findings may help doctors and dietitians offer more effective ways to prevent prediabetes from progressing to type 2 diabetes.
