[Changes in dietary intake of obese patients treated by diet associated with d-fenfluramine].

The object of the present research was to study the effect of dexfenfluramine (d-F) and placebo (P) on compliance with dietary treatment, especially as far as changes in kcal and macronutrient intake are concerned. A double-blind study d-F vs P was performed in 36 obese females, age range 20-59 years (mean 37.22 +/- 12.41), with a mean BMI of 33.95 +/- 5.36, suffering from obesity due to overeating without complications: Outpatient control every 30 days. The study protocol provided for a 14-month double-blind treatment with daily administration of either P (2 capsules) or d-F (two 15 mg capsules). Dietary prescription of 1200 kcal (5016 kJ) was given 15 days before enrollment (T/0) and during this period enrollment criteria were checked prior to randomization. Dietary intake was checked by a three-day recall (one working day, one half-holiday and one full holiday) in basal conditions and after 6-12 and 14 months. Administration of d-F and P brought about changes in alimentary behaviour in obese patients according to the dietary regime prescribed. In our patients, no highly significant differences between d-F and P were observed; however, the effect of P on macronutrient intake (carbohydrates, lipids and proteins) tended to peter out around the 12th month. Treatment with d-F reduced the consumption of simple carbohydrates, animal fats but not of animal proteins.
