Fat Signals Can Controls energy level in brainWhereas being overweight will bring a lot of difficulty, an optimal quantity of fat in your body may actually benefit as researcher have found that a key enzyme produced by fat helps the brain maintain its energy levels.

“We showed that fat tissue controls brain function in a really interesting way,” mentioned senior author Shine-ichiro Imai, lecturer of developmental biology and drug in St.Louis.

The researcher found that in mice the enzyme called NAMPT, secreted by fat tissues, affects the hypothalamus, a part of the brain known to have important roles in maintaining the body’s physiology, including regulating body temperature, sleep cycle, heart rate, Blood pressure, thirst and appetite.

“The results suggest that there is an optimal amount of fat tissues that maximizes the function of the control centre of ageing and longevity within the brain.” Said by Imai.

“We still do not know what that amount is or how it might vary by individual. However a minimum of in mice, we know that if they do not have enough of a key enzyme product by fat, an important part of the brain cannot maintain its levels of energy,” noted by Imai.

The finding may help explain the many studies that show a survival benefit to having a body mass index toward the low end of what is considered overweight.

For the present study, the researchers raised mice that lacked the capacity to create NAMPT merely within the fat tissue.

Mice with low NAMPT in fat tissue had low fuel levels within the hypothalamus. These mice additionally showed lesser measures of physical activity than mice exclusive of this defect.

Mice that expressed high levels of NAMPT within the fat tissue were extremely physically active.

The study appeared within the journal Cell Metabolism.
