Those who are markedly IR might be able to maintain a normal BMI of less than 25 kg/m2 when eating less than about 175 g carbohydrate/day. At higher intakes they would rapidly develop BMIs rated as either overweight or obese. Finally, those with severe and morbid IR are perhaps able to maintain a healthy BMI only on a miniscule amount of daily carbohydrate, perhaps less than about 25–50 g/day.
