AWM: Adults with Obesity BMI >/=30 (2020-21)

Intervention
In adults with obesity, what is the effect of weight management interventions provided by an RDN or international equivalent, compared to usual care or no intervention from an RDN, on BMI?
- Conclusion
  In adults with obesity, weight management interventions provided by a dietitian may reduce BMI. Interventions that included in-person contacts and group contacts were the most efficacious compared to controls in sub-group analyses.
- Grade: Low (C)
  - Grade I means there is Good/Strong evidence supporting the statement;

In adults with obesity, what is the effect of weight management interventions provided by an RDN or international equivalent, compared to usual care or no intervention from an RDN, on percent weight loss?
- Conclusion
  In adults with obesity, weight management interventions provided by a dietitian increased percent weight loss and increased the likelihood of achieving 5% weight loss. Interventions that included a multi-disciplinary team and at least 5 contacts with a dietitian were the most efficacious compared to controls in sub-group analyses.

In adults with obesity, what is the effect of weight management interventions provided by an RDN or international equivalent, compared to usual care or no intervention from an RDN, on fasting blood glucose?
- Conclusion
  In adults with obesity but without Type 2 Diabetes Mellitus (T2DM), weight management interventions provided by a dietitian likely result in little to no difference in fasting blood glucose (MODERATE). However, in adults with obesity and T2DM, weight management interventions provided by a dietitian may reduce fasting blood glucose (LOW).
