Overweight and Obesity is considered as the main chauffeur for an umbrella of diseases like type 2 diabetes mellitus, insulin resistance (IR), non-alcoholic fatty liver, hypertension, dyslipidemia, heart diseases, orthopedic disorders, asthma, hormonal imbalances, several types of cancers, disability, and many other types of diseases. The fundamental causes of overweight and obesity are a result of positive energy balance between energy intake and its expenditure or a combination of both. The World Health Organization (WHO) has reported that obesity more than 1.9 billion adults were overweight; of these over 650 million were obese in the year 2016. It was also reported by WHO in the year 2019 that 38.3 million children under 5 were overweight or obese [1]. There are an array of factors that leads to overweight and obesity which include age, gender, genetic predisposition, sedentary lifestyle, socio-economic status, faulty eating habits (processed and energy-dense foods), and so on.

Generally, weight management is focused on two modifications i.e., lifestyle modification and improving eating habits. It is well known that the principal depot for energy storage is WAT and on the contrary basis, BAT is responsible for thermogenic

energy expenditure. BAT had a significant capacity to dissipate energy and regulate triglycerides and glucose metabolism; act as a potential target for the treatment of overweight and obesity as well as metabolic disorders [2].
