VIDAL-GUEVARA, Mª. L. et al. Meal replacement as a dietary therapy for weight control: Assessment in males and females with different degrees of obesity. Nutr. Hosp. [online]. 2004, vol.19, n.4, pp.202-208. ISSN 1699-5198.

Obesity is a metabolic disorder characterized by an increase in the fat in adipose tissue above certain limits, manifested by morphological alterations and excess weight. This condition is one of the most significant epidemics of this century due to over-eating and the ease of access to food. On the other hand, the direct relationship between obesity and the greater risk of suffering cardiovascular disease, diabetes or cancer means that consumers are demanding products, whether medicines or foodstuffs, that will allow them to overcome this situation and improve both their physical appearance and their health. The goal of this project was to identify the efficacy and safety of a dietary product, a meal replacement, within the setting of a balanced hypocaloric diet established for weight loss. To this end, a total of 47 volunteers of both sexes between the ages of 23 and 58, all employees of the Hero España, S.A. company, took part in a test in which eleven of them acted as the "control group" and ate only the low-calorie diet while the rest formed a "problem group" and replaced one meal (with a minimum of 500 calories) with a 200-calorie meal replacement. Participants were subjected to anthropometric measurements, blood pressure testing and a blood chemistry analysis before and after the test period, as well as to weekly weight checks. Those individuals with the highest Body Mass Index showed a greater weight loss than those with a lower index. The volunteers did not note any hunger pangs until three hours after consumption of the meal replacement and the health-status parameters analyzed did not show any anomalous values. Therefore, it is concluded that the replacement product studied allows controlled weight loss over 3 weeks when accompanied by a balanced low-calorie diet and it also produces a sensation of fullness in those consuming it.
