Long-term excess energy intake leads to the accumulation of fat in the liver and pancreas that causes T2D, and calorie restriction can decrease intra-organ fat and put the disease into remission.[1] There is some evidence that high intake of added fructose, in particular, raises the risk of T2D.[2] However, any dietary pattern can be effective for treating and preventing T2D as long as it facilitates an energy deficit and promotes sustained weight loss.[3]

Diet affects type 2 diabetes (T2D) by influencing energy intake; excess calories can lead to fat accumulation in the liver and pancreas, but calorie restriction may help reduce this fat and potentially shift the disease into remission. Additionally, any dietary pattern that creates an energy deficit and supports weight loss can be effective in treating and preventing T2D.
