This is a dangerous myth. You can ABSOLUTELY help prevent Type 2 diabetes since it's linked to being overweight and sedentary. Diabetes affects blood sugar levels, leading to insulin imbalances that affect fat, muscle and liver cells. Studies have shown that those at risk can prevent or delay the onset of diabetes by losing 5 - 7% of their body weight. For example, if someone at risk weighs 200 lbs., losing just 10 lbs can have a meaningful impact. Try substituting whole wheat for white bread, eating fewer processed foods, and increasing physical activity; like taking 20 minute walks several times a week. Diabetes can cause heart disease, stroke, blindness, kidney failure, pregnancy complications, lower-extremity amputations, and deaths related to flu and pneumonia. An estimated 41 million U.S. adults have prediabetes-meaning that they are on their way to developing the disease. And for this subset, PREVENTION is even MORE key!
