Cheer up, take a slimming pill

A weight loss pill which claims to shed 2,000 calories a week and make you smile has gone on sale here.

Capsiplex Plus, which was dubbed the "happy slimming pill" in the US, also claims to boost moods.

It contains capsicum which is said to burn calories by raising serotonin levels, reducing appetite and increasing metabolism.

The pills, which will be available in Harrods and pharmacies, sold out within three days of their launch in America and advance UK orders already top 25,000 in Britain.

A spokeswoman said: "Mood has been linked to calorie intake, and it's proven that if we are feeling down our instinct is to 'comfort eat', thus we pile on the pounds and our mood sinks lower in a vicious circle.

"We wanted to launch a weight loss aid which would uniquely tackle both weight gain and depressive feelings."

Brad Pitt is said to be a fan, but doctors still warn that there is no better weight loss aid than eating less and moving more.
