Weight Loss: Rev Up Metabolism With This Popular Beverage

In a recent Scientific Report published by Nature Journal, a research team from the University of Nottingham and the UCLA School of Medicine discovered that the caffeine in coffee has a direct effect on brown fat activity in humans.

Brown Adipose Tissue (BAT), more commonly referred to as brown fat, is a unique variation of fat cells found in the human body, which was proved to have an increasingly positive correlation with energy metabolism in a study published in the Oxford Academic Journal in 2013.

Brown fat, as opposed to the calorie-containing white fat, produces heat and increases energy consumption in the body, the study showed. This opens up a world of possibilities in the treatment of Obesity and other metabolism-related illnesses such as Diabetes and Heart Disease.

Activated in cold conditions, brown fat cells are typically found in small numbers in the neck and shoulders of most people, which is in direct contradiction with the previous notion that these cells do not persist in the body beyond the stage of infancy.

The new study, which measured the response of BATs to the consumption of coffee, found that the caffeine in coffee greatly stimulated these cells' activity. "Increasing its activity improves blood sugar control as well as improving blood lipid levels and the extra calories burnt help with weight loss," said Michael Symonds, a professor at the School of Medicine at the University of Nottingham, who co-directed the study.

While Dr David Agus, a professor of Medicine and Engineering at the University of Southern California Keck School of Medicine and Viterbi School of Engineering shared that there are other means by which brown fat may be stimulated in the body, including exercise and deep sleep, Symonds said, "it's all about overall energy balance" so people who are inactive, or have an unbalanced diet will "counteract any stimulation of brown fat (from) coffee."

Caffeine has previously been discovered to reduce the risk of early death by 8-15 percent, and even prevents some variations of cancer. However, it is ill-advised to consume more than 3 cups of coffee in a day, as it may also lead to symptoms of Anxiety and sleep impairment.
