Let me present a few evidence-supported facts on this subject. This will help you make deductions.
Overweight and obesity are significantly associated with diabetes, high blood pressure, high cholesterol, asthma, arthritis, and poor health status. Intentional weight loss reduces the risk of overweight people developing diabetes. Obesity and type 2 diabetes both are preventable and require continuing effort to incorporate a balanced diet and physical activity in the lifestyle. These changes aim to achieve healthy weight loss. (Mokdad et al., 2003)
Clinical trials show that as little as 5% weight loss can prevent most obese subjects with impaired glucose tolerance from developing type 2 diabetes. (Astrup et al., 2000) The partial reversibility of the evolution of obesity towards diabetes occurs with lifestyle changes and weight loss programs. (Felber et al., 2002)
Type 2 diabetes is a disease characterized by progressive insulin resistance that typically accompanies advancing age, inactivity, and weight gain. The disease accounts for substantial morbidity and mortality. Diabetes enhances cardiovascular risk and increases the chances of developing other complications such as blindness and renal failure. There exists a linkage of type 2 diabetes with the genome. (McCarthy, 2010)
