What food do you eat on a keto diet?
Most keto meals are built from meat, fish, eggs, non-starchy vegetables, natural fats like olive oil and butter, plus cheese, nuts and seeds in moderation. The idea is to keep carbohydrate low while getting enough protein and letting fat fill the rest of your energy.
Building Meals Around Keto-Friendly Foods
The foods that fit a ketogenic diet share one thing in common: they are low in digestible carbohydrate. That leaves a surprisingly wide menu of whole foods to work with, so the practical question is less about a short list of "allowed" items and more about how you combine them into balanced meals.
Core foods to build from
Protein sources: beef, poultry, pork, lamb, eggs, and fish such as salmon, mackerel and sardines. Non-starchy vegetables: leafy greens, broccoli, cauliflower, zucchini, peppers, asparagus and mushrooms. Natural fats: olive oil, butter, avocado and avocado oil. Extras in moderation: cheese, full-fat dairy, nuts, seeds and berries. Water, tea and coffee without sugar round out most days.
How much of each
Rather than eating fat freely, aim for a plate where protein and vegetables take up most of the space and added fat is used to cook and finish the meal. The right amounts depend on your body size, activity and goal, so it helps to see numbers for your own details. You can estimate your keto macros and use them as a target while you learn portion sizes.
Foods to limit or avoid
Bread, pasta, rice, potatoes, sugary drinks, most fruit and sweets are usually kept out because they push carbohydrate up quickly. Many packaged "low-carb" products still contain more carbohydrate than they suggest, so checking labels is worthwhile.
A simple way to start
Pick a protein, add one or two non-starchy vegetables, and cook with a natural fat. Repeat that pattern across breakfast, lunch and dinner and you have a keto day without much planning. As you get comfortable, you can vary the ingredients to keep meals interesting. For more everyday questions about foods and rules, you can browse the full keto diet FAQ.
