Are low-carbohydrate (less than 45%) hypocaloric diets safe and effective for long-term (more than six months) weight loss or maintenance? (DGAC 2010)Conclusion
A moderate body of evidence demonstrates that diets with less than 45% of calories as carbohydrates are not more successful for long-term weight loss (12 months). There is also some evidence that they may be less safe. In shorter-term studies, low-calorie, high-protein diets may result in greater weight loss, but these differences are not sustained over time. Grade: Moderate Overall strength of the available supporting evidence: Strong; Moderate; Limited; Expert Opinion Only; Grade not assignable
