[Effect of different dietary programs on serum monoamine oxidase activity in patients with obesity].

MAO activity was studied in 116 patients with alimentary obesity (progressive, regressive and stable stages), placed on different food regimens. In the conditions of a negative caloric balance (deficiency of food calories) the patients with progressive obesity showed a significant reduction in the mean magnitude of MAO activity. The patients with stable obesity manifested MAO activity changes of different kinds under the same conditions.
