MNT: Effectiveness of MNT for Obesity (2009)
What is the evidence to support effectiveness of MNT provided by a Registered Dietitian for overweight/obesity in otherwise healthy adults?
Medical nutrition therapy (MNT) provided by a Registered Dietitian results in both statistically and clinically significant weight loss in otherwise healthy overweight and obese adults. Four studies regarding the effectiveness of medical nutrition therapy for under six months reported significant weight losses of approximately one to two pounds per week. Four studies regarding the effectiveness of MNT from six to twelve months reported significant mean weight losses of up to 10% of body weight. Four studies report maintenance of this weight loss beyond one year. In these studies, both individual and group sessions were employed with weekly and monthly sessions.
- Grade I means there is good evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited;
- Grade IV is Expert Opinion;
- Grade V is Not Assignable.
