[QUOTE="DCUK NewsBot, post: 1495079, member: 106455"] Even small amounts of exercise could be enough to help reduce insulin resistance, the hallmark of type 2 diabetes, according to new research. The US study sheds doubt on previous findings which had suggested that enhancing the small cell structures called mitochondria, which turn glucose and fats into energy, could help alleviate some symptoms associated with a high-calorie diet. The research team from the University of Arkansas said the amount of mitochondria was not directly affected by the amount of exercise carried out.
