A survey of opinions on the causes of and effectiveness for treatment
of obesity was carried out on data provided by questionnaires from 57
physicians and scientists involved in obesity research, Responses were
grouped by region (Europe, North America, and South America), gender,
age (30-50 and over 50 years), and professional training (MD or PhD),
Metabolic factors were considered the most important cause of obesity
overall with physical inactivity only slightly behind, There were no
gender differences, but the older group thought physical inactivity wa
s a more important cause th an the younger group, Weight cycling overa
ll was not considered very important, although it was significantly mo
re important among the Ph.D. group. Low-fat diets were considered the
most effective treatment, with the older group of respondents rating l
ow-fat diet more highly than their younger colleagues, Exercise was vi
ewed as a more important treatment among North Americans, and medicati
ons as less in the treatment of obesity, All groups viewed serotonergi
c and thermogenic drugs as the most effective treatments whose usefuln
ess would increase during the next 10 years.
