As a diabetic for many years, I have a very deep understanding of this topic. Diabetes is a chronic disease that, while not as deadly as cancer, causes widespread problems across the globe. Many people associate diabetes with obesity and think that as long as they control their weight, they can take care of their health. However, it's not that simple. 
First of all, I want to make it clear that obesity is indeed a risk factor for diabetes, but not all people with diabetes are obese. Diabetes type 1 is mainly caused by genetic factors, and people can develop this type of diabetes whether they are obese or not. Diabetes type 2 is usually lifestyle-related, which includes diet, exercise, and weight management. While obesity is one factor, other factors such as genetics, age, ethnicity, and metabolic status are equally important. Therefore, diabetes cannot simply be blamed on obesity. Second, even the association between obesity and diabetes is not absolute. There are many obese people who do not develop diabetes, while some people of normal weight do. This suggests that obesity is not the only risk factor, and that there are other factors that also play an important role in the onset of the disease. For example, family history, high cholesterol, high blood pressure and lack of exercise can all increase the risk of disease. Therefore, it is inaccurate to simply equate the problem of obesity with diabetes. 
Also, diabetes isn't just a weight issue. It is a metabolic disorder characterized by an abnormally high blood sugar level. Even if there are no obvious symptoms of obesity, people can still develop diabetes. Proper management of diabetes requires a comprehensive consideration of diet, exercise, medications** and blood glucose monitoring. Controlling diabetes simply by ** is one-sided, as it does not address the influence of other factors on the development of the disease. Finally, it is important to emphasize that many views on diabetes and obesity are based on scientific studies and clinical trials. These views are not speculation or rumors. Scientists are constantly working to study the causes and methods of diabetes in order to provide better help to patients. We can't simply reduce obesity and diabetes to rumors, as this can lead people to ignore other risk factors for the disease. 
In conclusion, the problem of diabetes and obesity is not a simple relationship, but the result of a combination of factors. Obesity may be a risk factor for diabetes, but it's not the only one. The occurrence and development of diabetes requires a comprehensive consideration of a variety of factors, including age, lifestyle, genes, etc. Therefore, we cannot prevent and ** diabetes by controlling our weight alone, we need to take a combination of measures.
