Grappling with the truth

Small post to say I am grappling with two papers that are full of science speak and gobbledygook. But if I am understanding the papers correctly they seem to be saying that obese people and/or type two diabetes people physiologically find it harder to loose weight. It would appear that at a cellular level they burn energy differently than normal, with normal people burning up fat when they exercise, but the obese/type II diabetes do not.

Once I have wrestled with the papers some more I will attempt to explain this is easier understandable words!
