For some people, the answer is yes.
New research reveals that we all have a “carbohydrate tolerance level”. Put simply, this is the amount of carbohydrate intake an individual can tolerate before they show signs of metabolic disturbance. All individuals sit on a spectrum in this regard.
Carbohydrate consumption is not detrimental to health – it is carbohydrate intake beyond the individual’s metabolic capacity which causes problems. Some signs that an individual is exceeding their carbohydrate intolerance include: gaining weight easily, difficulty burning fat, carbohydrate craving, fatigue & sleepiness after a carbohydrate meal, fatigue during exercise, elevated blood sugar levels, high waist circumference, high blood pressure and elevated triglycerides (fats) in the blood.
When we consume carbohydrates beyond our capacity (tolerance level), the body begins to convert the excess sugars to fat. For example: if the liver is exposed to high concentrations of glucose (sugar), it activates fat synthesising enzymes, causing fatty acid production. High levels of these fatty acids are linked with metabolic syndrome & Type 2 diabetes. This results in laying down extra fat in the liver, or the fats may be transported into the blood, causing elevated blood fats and impairing insulin production.
