Putting on some weight lately
Sugar has no proteins or fibers and it does not make you feel satiated so you just keep eating it. Excess sugar is just excess calories. Also, it causes the release of insulin, the hormone that is very important in weight gain. When eating sugar the pancreas releases insulin, which brings sugar to the organs so it can be used for energy.
When loaded up on sugar, the body produces more insulin and over time it causes insulin resistance. It means that the body cannot respond to normal amounts of insulin properly and thus can’t use sugar properly.
Weight gain from eating too many calories from sugar is further caused by the normal insulin response. Also, when the pancreas functions ultimately for too long it can develop diabetes.
