A set of meaningful, measurable treatment criteria based on the naturopathic practice principles were defined that could have generated the majority (82%-93%) of treatment prescriptions given at visits for these conditions. Several of the treatment criteria components are common across the 3 conditions studied, and might be appropriate for all visits to doctors of naturopathy (NDs).

While no one eating occasion contributes more than any other to excess adiposity, eating more often than three times a day may play a role in overweight and obesity in both younger and older persons. A reduced satiety response to dietary fiber in addition to lower energy expenditure may potentially further contribute to weight gain in older persons.

Of 27 clinical trials testing massage or mind-body interventions, 26 showed significant improvements in symptoms such as anxiety, emotional distress, comfort, nausea and pain. However, results were often inconsistent across studies and there were variations in methodology, so it was difficult to judge the clinical significance of the results.
