                                Studies suggest that completely restricting carbohydrates, as with the carnivore diet, shifts the body into ketosis, burning fat for fuel instead of glucose. However, this restrictive nature brings up questions about common food items, prompting many to ask, 'Can I have a little ketchup on a carnivore diet?' The short answer is no, due to the sugar and plant-based ingredients in conventional ketchup, but compliant alternatives exist.
