The ketogenic (keto) diet is a low-carbohydrate, high-fat eating pattern that shifts your body into a metabolic state called ketosis. In ketosis, your body burns fat for fuel instead of glucose. Most keto diets limit net carbs to 20-50g per day.
Net carbs = total carbohydrates minus fibre. Fibre is a carbohydrate your body doesn’t fully digest, so it has minimal impact on blood sugar and ketosis. When assessing keto suitability, net carbs are what matter most.
Many foods contain sugars disguised under different names — glucose syrup, maltodextrin, dextrose, and others. These hidden sugars add unexpected carbs that can push you out of ketosis, even if the product appears low-carb on the front of the packaging.
Ultra-processed foods (NOVA 4) often contain hidden carbs, industrial sugars, and refined starches that can undermine keto goals. Whole, minimally processed foods are generally safer choices for maintaining ketosis. Keto is not just about carbs — ingredient quality matters too.
