Good fat vs bad
Good fat vs bad fat, which of yours is winning? According to the study, the “good” fat (brown) located behind our necks and shoulders, which burns the “bad” fat (white) that accumulates on our stomachs and thighs, diminishes as we age. The exercise needed to burn a sufficient number of calories begins to increase because a slower, less industrious metabolism replaces the heavy lifting once performed by the brown – good fat. Fortunately, the team’s new research suggests the existence of a metabolic on/off switch that may delay this process.
“A common complaint is that older people have to work twice as hard with their diets and exercise to get half of the results of younger people,” said Dr Gerald Weissmann, Editor-in-Chief of The FASEB Journal that published the study.
“Now we have a much better idea why this is the case – our good fat (brown) stops working as we age. Unfortunately, until a way to turn it back on is developed, we’ll have to be prepared to eat more salads and lean proteins, while logging more miles on the treadmill than our younger counterparts.”
In the latest study, the Japanese researchers also found a possible metabolic switch that could reactivate brown fat. This discovery could pave the way for the development of new treatments for obesity-related conditions such as diabetes, heart disease, high blood pressure and some cancers.
