No. It has no effect. Diabetes is a disease involving sugar and a hormone : insulin. If you happen to be pre-diabetic AND you're fat, losing weight will help ... it may even prevent the disease from occurring. (Because the fat cells effect your ability to utilize the insulin that your body has.)
diabetes
