AWM: Low Carbohydrate Diet (2006)

 

• Intervention
  In adults, how effective, in terms of weight loss and maintenance, are low carbohydrate diets (defined as <35% kcals from carbohydrate)?

  • Conclusion

     

     

    Consumption of ad libitum low-carbohydrate diets and reduced calorie diets both result in lower caloric intake. However, ad libitum low carbohydrate diets resulted in greater body weight loss and fat loss in the first six months. After one year, these differences are no longer significant.

    In comparison studies of diets designed to be isocaloric, there were no significant differences in body weight or fat loss during the first six months of consumption of low carbohydrate diets compared to other diets.

    Further research is needed to clarify why these differences exist within the first six months.

  • Grade: II
    • Grade I means there is Good/Strong evidence supporting the statement;
    • Grade II is Fair;
    • Grade III is Limited/Weak;
    • Grade IV is Expert Opinion Only;
    • Grade V is Not Assignable.
    • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
    • Moderate (B) means we are moderately confident in the effect estimate;
    • Low (C) means our confidence in the effect estimate is limited;
    • Very Low (D) means we have very little confidence in the effect estimate.
    • Ungraded means a grade is not assignable.
