An evaluation of the efficacy and acceptability of 'Slender' in refractory obesity.
A formula diet 'Slender' was assessed in 55 patients with refractory obesity. During the initial 12 weeks of the study, the subjects were instructed to take a carbohydrate restricted diet designed to provide 1000 kcal (4.2 MJ) per day. They were then advised to replace up to four meals a day with a packet of Slender. Of the 42 subjects completing the study, 21 stopped taking Slender after six weeks and 21 completed 12 weeks. During the pre-Slender treatment, the mean weight gain was 1.7 kg. This contrasts with a mean weight loss during the first six weeks of treatment with Slender of 1.9 kg. Those continuing to take Slender for 12 weeks lost 3.7 kg and subjects who said that they had adhered strictly throughout the trial period had a mean loss of 4.6 kg. The overall results are relatively disappointing but are similar to that which can be achieved with other forms of therapy in comparable patients. If there is use for Slender, and other similar products, it may be the prevention of obesity rather than in the management of the morbidly obese.
