Most people are under the impression that starchy foods such as bread and potatoes make you fat.
This is not the case – unless you cover your bread and potatoes with high-fat foods such as cheese, butter or sour cream.
Excess sugars and carbohydrates are stored as glycogen – not fats. Carbohydrates are not converted to fats. Animals, bacteria and fungi convert glucose to glycogen which is the form that glucose is stored.
Except in abnormal, extreme conditions, carbohydrates are not converted to fat in humans.
Fats make you fat – not carbohydrates.
