Trial Dates: 1 June 2001 - 25 July 2001 (8 weeks)
SUMMARY: 12 volunteers completed an eight week course of Slendernight in accordance with the instructions. These instructions were to refrain from eating or drinking anything apart from water, unsweetened grapefruit juice or herbal teas, for 3 hours before going to sleep, and to take one tablespoon/ 15ml of Slendernight in a 200ml glass of water, immediately before going to sleep. Otherwise they were to eat a normal, balanced diet and do no special additional exercise. The volunteers who enrolled all wished to improve their figures and lose some fat. They completed a registration form and signed their consent. Each completed a simple test for the presence of excess yeast in their digestive system and for any thyroid imbalance, as these factors are claimed by the manufacturers to inhibit the proper function of collagen hydrolysate supplementation (and other means of slimming). The baseline evaluation was conducted on 1st June, with interim monitoring at 4 weeks, and full evaluation after 8 weeks. There was final informal monitoring at the end of August (12 weeks). The full evaluation was conducted after 8 weeks, because of the problems of pursuing the test over the August summer holiday period. However all volunteers were given sufficient Slendernight to complete the normally recommended three month course.
