Overweight and obesity is based on Body Mass Index (BMI) Accordingly to the World Health Organization (WHO) classifies individuals with BMI 25-29.99 kg/m2 as overweight while individuals with BMI≥ 30 kg/m2 are termed obese. Apart from being a major contributor to chronic disease burden and mortality, obesity-particularly abdominal obesity, is also closely related to the metabolic syndrome, a cluster of diseases that encompasses the following conditions Dyslipidemia, Hypertension Glucose intolerance and insulin resistance.Abdominal obesity The World Health Organization predicts there will be 2.3 billion overweight adults in the world by 2015, and more than 700 million of them will be obese. Worldwide obesity has more than doubled since 1980. In 2008, 1.5 billion adults, 20 years of age and older, were overweight. Of these, over 200 million men and nearly 300 million women were obese. Over 65% of the world population lives in countries where overweight and obesity kills more people than underweight .

Overweight and obesity have become a serious health concern . Different weight management strategies are presently utilized and a variety of weight loss supplements sold as "slimming aids" are readily available. However, the efficacy of some of these food supplements remains uncertain. With the high cost of prescription weight loss drugs and the fear of side effects, the general public is turning to nutraceuticals. One such supplement is the green coffee extract (GCE).GCE is present in green or raw coffee.

Coffee (Coffea L.) is the world's favourite beverage and the second-most traded commodity after oil. In 2009/10 coffee accounted for exports worth an estimated US$ 15.4 billion, when some 93.4 million bags were shipped, with total coffee sector employment estimated at about 26 million people in 52 producing countries. Arabica coffee (Coffea arabica L.) and robusta coffee (C. canephora Pierre ex A.Froehner) are the two main species used in the production of coffee. 66% of the world production mostly comes from Coffea arabica L. and 34% from Coffea canephora. Coffee belongs to family Rubiaceae in the genus Coffea.

GCB-70 is obtained from raw seeds or beans of Coffee. In producing the normal coffee for sale, the berries are roasted to produce the traditional beverage. However, no roasting is done for green extract so as to preserve important components
