Why can't diabetics lose weight?
This is very common. This is because when you are insulin resistant or have Type 2 diabetes, it becomes very easy to gain weight. This is because it not only depends on your diet but also your genetics or the environmental factors. You also have to make sure that you focus on your diet and exercise.
There is something called lifestyle change which is extremely important but not necessarily very easy. You should set realistic expectations for yourself and your body. It is very important to feel accountable for your behavior. This can only happen if you keep monitoring yourself and feel accountable and take responsibility for your body.
