Weight gain is one of the signs of type 2 diabetes. It occurs due to insulin therapy, a common treatment for diabetes. When insulin, which is responsible for absorbing glucose for energy production, absorbs too much sugar from food during the process, the body converts it into fat. Excessive fat storage leads to weight gain. The problem with diabetics is that they have to be very specific about what they eat. Therefore, when it comes to shedding kilograms and maintaining a healthy weight, they should be more careful in their eating habits and diet because an incorrect diet can aggravate their symptoms.
