How Long Does Sugar Last in the Body?

According to Aglaee Jacob for SFGate, depending on the type of sugar consumed, the body can take anywhere between one and four hours to metabolise it, although blood sugar can start to climb right away. Lower glycemic index foods have less of an effect on blood sugar levels.

During the digestive process, both carbs and starches are converted into simple sugars. According to Jacob, eating a well-balanced meal with proteins, fibre, and healthy fats can reduce the rate at which blood sugar levels rise because these meals take the body longer to digest.

According to the University of Maine Cooperative Extension Publications, people with diabetes must be extra aware of their sugar intake because their bodies do not manufacture as much insulin as “normal” people’s bodies do to assist regulate blood glucose levels.
