While on a carnivore diet, you'd want to avoid anything that isn't meat. To be more specific, this means customarily classified healthy foods like fruit and veg. For most people, this will be the biggest adjustment.You should also avoid sauces and most seasoning. Salt and pepper are fine, but the focus should be purely on meat as nature provides it.Highly processed meat is also best avoided, and this includes a lot of sausages. Many of these products contain things like cereal, starches, and even sugar -- so avoid them unless you're 100% certain it's pure meat.Unfortunately, you also have to avoid alcohol, including beer and wine. These are very heavy in carbs and will cause all sorts of problems for your carnivore diet efforts.
