The use of low calorie diet supplement in weight reduction: A preliminry report.

Low calorie diet (LCD) supplement has gained popularity in weight control programs. The efficacy, acceptance and adverse effects of LCD (Modellim 40R, Medicfast) were evaluated during a 12 week weight reduction program in 11 obese volunteers. They were 2 males and 9 females, age 37.4 + 9.4 year old (mean + SD) whose body mass indices (BMI) ranged from 28.8 – 40.7 kg/m2 (mean + SD = 31.44 + 4.84). During the weight reduction period, a diet containing 800 kcal/day was prescribed in every case with a supplement of 1 packet of LCD (40 kcal) before lunch and dinner, and whenever they felt hungry. Regular exercise were also encouraged. At the beginning and at the end of the program, blood specimens were analysed for liver, kidney and thyroid function, electrolytes and other macro minerals. Lipid profiles and complete blood count were also done. All volunteers were interviewed and examined initially and every 2 weeks thereafter by one of the investigators. One female volunteer was withdrawn from the study after the first week because of aversion to LCD. The others tolerated the LCD well. They were consumed 1-3 packets daily (mean + SD 1.44 + 0.7). At the end of twelfth week, the weight loss was 3.1 + 2.9 kg (range -1.4 – 8.1 kg). There was no well-accepted in most of the cases and can be used as a supplement during weight reduction without any serious side effects.
