Opuntia, the weight-loss cactus
You can buy them in any drugstore: slimming supplements containing fibre from the cactus Opuntia ficus-indica. You can see the plant in the drawing below. The supplements go by the name of Proactol, Prickly Pear Cactus or simply Opuntia. According to a sponsored human study, published recently in Current Therapeutic Research, the supplements may actually work. A little. A teeny weeny bit.
Study
Fat excretion
When the subjects took a placebo they lost about 4.6 percent of the fat in their diet through excretion. When they took the Opuntia fibre this increased to 15.8 percent.
Expressed in grams this meant that the subjects lost 4.3 g fat if they took the placebo and 15.1 g fat if they took the supplement. That’s a difference of 10.8 g fat or 97 kcal per day.
Do the sums
If you walk you burn 3.5 kcal per kg bodyweight each hour. So if you weigh 70 kg you lose the 97 kcal in just 24 minutes of walking.
Another example: jogging burns 7 kcal per hour per kg bodyweight. So if you weigh 70 kg you'll burn the 97 kcal in just 12 minutes of jogging.
You can see why we're sceptical.
