Intervention
In adults, what is the long-term maintenance (at least 1 year) of weight loss following a Very Low Calorie Diet (VLCD, defined as 800 kcals or 6 - 10 kcal/kg)?
-
Conclusion
While adherence to a very low calorie diet results in significant initial weight loss, studies report varying levels of weight regain based on differences in weight maintenance strategies.

Grade: I
- 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.
In adults, how effective (in terms of client adherence and weight loss) are very low calorie diets (defined as 800 kcals or 6 - 10 kcal/kg)?-
Conclusion
Adherence to a very low calorie diet, defined as 800 kcals or 6 - 10 kcal/kg or less, results in significant weight loss.

In adults, how effective (in terms of client adherence, weight loss and maintenance) are VLCDs, compared to LCDs and other interventions?-
Conclusion
Adherence to a very low calorie diet results in lower caloric intakes and therefore significantly greater initial weight loss than reduced calorie diets.
