Sedentary lifestyle and caloric overconsumption are the key determinants of the escalating obesity prevalence. Reducing dietary fat absorption may help to induce a negative energy balance and thus help in managing weight problem. Apart from approved drug therapies, weight problems may also be aided with alternative and natural treatments. This paper compiled and reviewed the efficacy and safety of Litramine IQP-G-002AS, an Opuntia ficus-indica (OFI) derived fiber, in reducing dietary fat absorption and promoting weight loss. Evidence reviewed shows that Litramine IQP-G-002AS displays efficacy in promoting fat excretion and weight loss in four randomized, placebo-controlled clinical studies (including an unpublished pilot study). With a daily dosage of 3 g over a seven-day period, Litramine IQP-G-002AS showed an increased faecal fat excretion compared with placebo (15.8% (SD 5.8%) versus 4.6% (SD 3.1%); P < 0.001). In a 12-week study, significant greater weight loss (3.8 kg (SD 1.8 kg) versus 1.4 kg (SD 2.6 kg); P < 0.001) was observed in overweight and obese subjects treated with Litramine IQP-G-002AS as compared to placebo. No relevant gastrointestinal side effects have been reported for Litramine IQP-G-002AS at the dosages studied.
