Question: how many grams of sugar can you have on the keto diet a day?
Answer: So while sugar is a carb and does count toward your 50 grams or fewer a day, you should still limit sugar intake so as not to spike your blood sugar. Yes, you can still have it, but make sure that sugar, combined with all your other sources of carbohydrates, stays below your threshold of about 50 grams a day.
