Diabetes caused by insulin resistance due to obesity, this type of patient can indeed reduce blood sugar by losing weight. This is because the fat content in the body is too high, resulting in the accumulation of fat in the cells and insulin resistance, and glucose is not well used by the cells, and the accumulation of glucose in the blood vessels for a long time will cause blood sugar to rise. Through weight loss, the content of fat in the cells decreases, the function of insulin resistance also decreases, the cells can make good use of the glucose in the blood, so that each tissue and organ gets the corresponding nutrients, the blood sugar in the blood vessels will drop, so through weight loss can indeed lower blood sugar.
