Discover practical tips for keeping costs low on keto and explore the most affordable, nutrient-dense foods to prioritize at the grocery store.
What is keto?
The ketogenic diet, often referred to as keto, is a low-carbohydrate, high-fat dietary approach designed to shift the body into a metabolic state known as ketosis. In ketosis, the body relies primarily on fat for energy rather than carbohydrates, producing organic acids called ketones as an alternative fuel source.
A typical keto diet emphasizes healthy fats, moderate protein intake, and very low carbohydrate consumption, usually limiting daily carbohydrate intake to around 20 to 50 grams of net carbs.
Although keto can be associated with high grocery costs, many keto foods are accessible and affordable.
Many people initially turn to keto to lose weight, though its potential benefits extend to a range of other health markers. A study published in Nutrients found that the keto diet has been associated with improvements in metabolic markers and other health outcomes.
The authors state that in recent studies, the keto diet showed “promise in helping patients lose weight, reverse the signs of metabolic syndrome, …reduce inflammation, improve epigenetic profiles, alter the microbiome, improve lipid profiles, supplement cancer treatments, and potentially increase longevity and brain function.”

Tips for following keto on a budget
Following a keto diet doesn’t have to increase grocery spending. With a few practical strategies, it’s possible to maintain a keto lifestyle and eat healthier while keeping food costs manageable.
Here are four money-saving tips that can make eating keto more budget-friendly.
1. Plan meals before going to the store
Planning meals in advance is one of the most effective ways to control food costs. A simple weekly keto meal plan helps ensure you purchase only the ingredients necessary and avoid unnecessary purchases.
Meal planning also allows you to build multiple meals around the same ingredients, stretching grocery purchases across several days and minimizing food waste.
For example, a whole chicken can serve as a main dish, leftover meat can be shredded for salads or lettuce wraps, and the bones can be used to prepare homemade broth.
2. Focus on whole foods
One of the biggest factors that increases the cost of following a keto diet is reliance on specialty products, such as keto bars and snacks.
Many of these processed foods are marketed as convenient options for a keto diet, but they frequently cost significantly more per serving than whole foods.
Foods such as eggs, ground beef, chicken thighs, pork chops, canned tuna, cheese, and non-starchy vegetables provide protein, healthy fats, and essential nutrients at a lower cost and can be used across a wide range of keto recipes.
3. Buy frozen foods
Frozen foods can be a practical and cost-effective option when following a low-carb diet. Frozen ground meats and produce are often less expensive than their fresh counterparts and can be stored longer without spoiling.
Budget-friendly vegetables include frozen broccoli, green beans, and Brussels sprouts, which can easily be added to keto meals such as stir-fries, omelets, soups, or casseroles. Frozen berries, such as blueberries, strawberries, or raspberries, can also be a cost-effective addition.
4. Know when to choose organic
Buying organic foods can increase grocery costs, but purchasing non-organic can be acceptable for certain foods. Some whole foods have natural protective layers or are only minimally exposed to pesticides, making non-organic options a practical and more affordable choice.
Foods such as avocados, wild-caught salmon, coconuts, and cabbage, as well as sea salt and certain nuts like walnuts and pecans, are generally considered lower priority for organic purchasing.
In contrast, it may be more important to choose organic options for foods that are more commonly associated with higher pesticide exposure, including strawberries, spinach, and peanuts.
“Ideally, buying 100% organic would be best,” Dr. Berg explains, “but if the choice is between non-organic whole foods and lower-quality processed foods, it’s better to choose the whole food option.”
