Caloric restriction (20-30% reduction) significantly improves cardiometabolic health by reducing body weight, BMI, fat mass, total cholesterol, and LDL, while having no significant effect on blood pressure or HDL.
To improve metabolic health, reduce your daily caloric intake by 20-30% while ensuring you still get all essential nutrients. Expect significant weight loss and improved cholesterol levels, but do not expect blood pressure or HDL changes to be guaranteed outcomes.
Meta-analyses proved benefit of CR on reduction of body weight, BMI, fat mass, total cholesterol, while a minor impact was shown for LDL, fasting glucose and insulin levels. No effect emerged for HDL and blood pressure after CR.
Why this rating
Based on a systematic review and meta-analysis of 8 RCTs with 704 subjects, though some heterogeneity and bias risks exist.
