Carbohydrate Restricted Dietary Approaches and Health Outcomes (CRDA) Systematic Review (2020-23)
Carbohydrate Restricted Dietary Approaches and Health Outcomes
The objective of this systematic review was to analyze the effect of carbohydrate restriction, focusing on three subtopics – adults with overweight or obesity and no other established disease; adults with overweight or obesity and metabolic dysfunction-associated steatotic liver disease (formerly nonalcoholic fatty liver disease); and adults with any weight status and type 2 diabetes mellitus. The expert panel reviewed research on anthropometric, glycemic, blood pressure, lipid outcomes and other outcomes.
Key Findings:
Intake of a low- or moderate-carbohydrate diet compared to a higher carbohydrate intake:
- likely reduces body weight, waist circumference, fasting blood glucose, HbA1c, and triglycerides in adults with overweight or obesity and no other established disease. (Moderate certainty)
- may have no effect on liver fat, AST and ALT enzymes, body weight and composition (BMI, waist circumference, fat mass, etc.), fasting blood glucose, HbA1c, blood pressure, total, HDL- and LDL-cholesterol and c-reactive protein in adults with overweight or obesity and metabolic dysfunction-associated liver disease. (Low certainty)
- likely results in a small reduction in body weight, BMI, waist circumference, and likely reduces total cholesterol and triglycerides in adults with Type 2 diabetes mellitus. (Moderate certainty)
