Scientists claimed to have developed a slimming pill that can burn off as many calories as 80 minutes of walk or a 25-minute jog, while you sit.

The pill -- Capsiplex -- which is made from hot peppers and capsicum, utilises the weight-loss potential of red-hot peppers.

Chilli and capsicum help speed up the metabolism, thus, helping people lose weight more rapidly. However, consuming these chillies or their extract in large quantities causes irritation as these are unbearably hot.

The scientists overcame this problem while developing the capsule. The pill eats up the calories without causing any irritation, the Daily Mail reported.

“For decades, scientists have known about the weight-loss potential of red-hot peppers. The problem has been the ability to consume such a highly concentrated amount, but we have overcome this by putting a protective coating on the ingredients which stops any gastric irritation,” a spokesman for Capsiplex said.

“At last we have a safe and healthy supplement to help weight loss,” the spokesman added.

Trials of the pill conducted at University of Oklahoma in US showed adults taking Capsiplex burned off 278 more calories before, during and after a bout of exercise than those on placebos.

The pill is already in use in the US. Hollywood stars like Jennifer Lopez, Brad Pitt and Britney Spears are known to have used the pill.
