Yes. Because ketchup is made from high fructose corn syrup and added sugar, it will kick you out of ketosis. Ketone production is triggered when there is inadequate blood glucose, and glycogen stores are low.

Eating ketchup introduces sugar into the blood, which is the body’s preferred source of fuel for energy. Once there is adequate blood sugar, the body stops breaking down fats and uses glucose as the primary source of energy. This is why ketchup is not allowed when you eat keto.
