A new pill that claims to help lose those extra calories, which one unwittingly adds up during festivals, in a pain-free calorie-burning process was sold out as soon as it hit the UK market yesterday.
Makers claim that one dose of Nuratrim can burn 380 calories-a-day, which is 15 times more than normal.
Advanced orders topped 50,000 as the product reached the UK on Tuesday and it sold out within hours when it was launched across the U.S. in October.
Mariah Carey, Kim Kardashian and Jennifer Aniston have reportedly used the tablet, which contains extracts of liquorice and green coffee to speed up digestion.
German creator Dr Alfred Hasslebacher said that the pill has been "been clinically proven to increase energy levels, suppress appetite, and burn fat".
"It has been devised to assist all men and women looking to lose excess weight and control their appetite," the Daily Mail quoted Dr. Hasslebacher as saying.
"This optimum formula has been clinically proven to increase energy levels, suppress appetite, and burn fat," he stated.
Nuratrim costs 34.95 pounds for 30 pills and is designed to be taken daily with breakfast.
Makers report that Nuratrim can burn as many calories as a 40 minute run, and the natural ingredient Glucomannan, absorbs water which swells the stomach to keep hunger at bay.
"Our extensive research showed how hard it is to achieve your ideal weight and size when the daily demands and pressures of your lifestyle impede on your good intentions," Dr. Hasslebacher explained.
"Nuratrim is an unique blend of pure ingredients that have thermogenic properties which naturally stimulate the body's metabolism by mimicking the effects of physical activity," he added.
Research involving 65 patients of average weight, found Nuratrim increased metabolic rate by 35 percent, reduced appetite by 78 percent and burned an additional 20 percent of fat.
Over an eight week period 90 per cent of those involved lost a minimum of 14 lbs without changing their diet or lifestyle.
