September 10, Metabolism involves the chemical reactions that break down the food we eat into sugars, fats, and amino acids. We use these compounds for energy to power our bodies. They may also be used to build new cell structures and machinery. Metabolism can be impacted by many factors, such as diet, genes, the environment, and daily activity. Brown fat breaks down blood sugar glucose and fat molecules to create heat and help maintain body temperature.

February 4, The majority of adults in the U. The last several decades have also seen a spike in related diseases of metabolism, such as type 2 diabetes. The human body contains more than one type of fat. White fat stores extra energy. Too much white fat, a characteristic of obesity, increases the risk of type 2 diabetes, high blood pressure, and other diseases.
Obesity is the consequence of chronic positive energy balance and considered a leading risk factor for cardiovascular and metabolic diseases. Due to its epidemic trends among children and adults, there is an increasing interest in implementing new therapeutic interventions to tackle overweight and obesity. Activation of brown adipose tissue BAT represents today a promising strategy to enhance energy expenditure EE through heat production. This minireview aims to summarize the current knowledge of some dietary compounds that have been shown to promote BAT activation and WAT browning with subsequent beneficial health effects. Obesity is defined as an abnormal body fat accumulation due to chronic periods of imbalance between energy intake and expenditure.
Brown adipose tissue BAT or brown fat makes up the adipose organ together with white adipose tissue or white fat. Classification of brown fat refers to two distinct cell populations with similar functions. The first shares a common embryological origin with muscle cells , found in larger "classic" deposits. The second develops from white adipocytes that are stimulated by the sympathetic nervous system. These adipocytes are found interspersed in white adipose tissue and are also named 'beige' or 'brite' for "brown in white" .
