How to make a low-carb or keto diet cheaper

How to make a low-carb or keto diet cheaper


Some low-carb foods can be very expensive and many people believe a low-carb or keto diet must be expensive. But that’s not true. You don’t need expensive products. You can eat delicious and healthy low-carb meals that are super cheap.

With a little planning and some smart shopping, you could save a lot of money. You’ll quickly learn how. 

1. Do this to save money

There are many things you can do straight away to save money, in these categories:

  1. Plan
  2. Shop
  3. Cook
  4. Eat

1.1 Plan

Planning your low carb meals and shopping is a great way to ensure meals are organised for the week ahead. You will buy only what you need, and you won’t be relying on emergency takeaways. See what’s in your cupboards and fridge already, then plan meals that will use these products to stop food wastage.

Planning shopping lists will help you stop unnecessary spending and impulse purchases. Did you know that each week we spend on average 17% of our grocery budget on impulse purchases?

Also, bargain deals may appear to be of good value. Check with your local supermarket when they put up discounted products and plan your shopping trip around that time. I do this every week, fill my freezer up and once a month or once in a couple of months and can easily skip one weekly shopping trip. But naturally, you save even more if you don’t buy additional foods at all.

Make a shopping list, and stick to it. Preferably only buy the things you need.

1.2 Shop

low-carb shopping planning

Buy cheaper alternatives

Some low carb foods can be ridiculously expensive, but there are plenty of cheaper options, simple and healthy, which are just as delicious.

  • Buy regular cheese, not specialty cheeses that are pricey. Don’t buy pre­shredded cheese, they contain added carbs/starch, buy in bulk and shred/grate it yourself.
  • Make your own coleslaw and avoid expensive ready-made coleslaw made with unhealthy oils and added sugar. Coleslaw is incredibly easy and cheap to make yourself in your food processor (recipe).
  • Buy simple meats, not specialty cooked meats from the deli. Cooked meat can be great for a quick simple meal but stick to the less exotic and cheaper meat such as cooked roast beef or chicken drumsticks.
  • Put back the kale that can cost a fortune and buy other leafy greens that are just as nutritious but much cheaper.
  • Stop buying nuts because they can soon add up, especially macadamias. Walnuts, almonds and brazil nuts are great alternatives or stop buying them altogether.
  • Buy an almond meal/ground almonds, not almond flour which is expensive. Almond meal/ground almonds are cheaper and interchangeable in most recipes. You can even make your own ground almonds in your coffee grinder.
  • Buy avocado oil not avocados when they are out of season and expensive. (This one is my favourite swap)
  • Buy frozen or canned fish rather than fresh which can be a real budget breaker, especially salmon. Canned tuna and mackerel are cheap handy snacks to have in the cupboard.

Buy the best quality you can afford

Organic vegetables have fewer pesticides, grass-fed meat has superior nutrition and free-range eggs are nutritious but expensive. Unfortunately, these are simply out of the reach for those who need help the most, and who are living to a strict grocery budget.

For someone living on a diet of sodas, fries and fast food, swapping to regular eggs, regular vegetables and regular meat will still have an enormous impact on their health. The single most important factor to improve your health is to cook from scratch, at home.

Buy free-range eggs as often as your budget will allow, but regular eggs will still be a better breakfast option than high­-sugar cereals.

Buy in season

Buy in season and eat in season. Many vegetables can be bought when they are cheap and frozen. There are many cheap low-­carb­ freezer staples such as berries, spinach, and cauliflower which are just as nutritious as fresh but much cheaper.

Buy bargains

Buy cheaper store brands, buy discounted food near its expiry date, buy misshapen vegetables, buy food with damaged packaging, buy from your local farmer’s market, and buy regular food not specialty foods from the deli counter.

Buy in bulk

Find a local butcher, and buy in bulk. Buy canned and frozen goods when they are discounted. Buying in bulk often attracts extra discounts and you know you will have a pantry and freezer full of ingredients just waiting to be turned into a meal.

Buy organ meat

Organ meat is incredibly cheap and very nutritious.

Liver gram for gram provides more nutrients than almost any other type of meat. If you don’t like eating liver, use it diced finely in a dish such as a chili to bulk up the ground beef. The liver is cheap and incredibly nutritious.

Buy cheaper cuts of meat

Don’t buy the expensive lean meats, buy the cheaper fatty ground meat, buy the fatty pork chops, and buy the cheap chicken that still has the skin on.

Buy the cheap casserole/stewing meat and learn to love your slow cooker. It will transform cheap cuts of meat into a tender meal.

Find a local butcher who sells pork skins to make your own crackling which is a perfect low carb snack.

Use bones from a roast dinner or from the butcher to make bone broth.

1.3 Cook

cook at home

Cook once, eat twice

Leftovers are the champion of low­-carb living. Cook extra portions and only go back for seconds if you’re still hungry. Leftovers are a fantastic way to eat an affordable healthy low-carb meal for lunch or dinner.

If there is a special discount in the grocery store, buy in bulk, cook in bulk, then freeze extra portions. You will have a happy freezer full of cheap healthy low-carb ready meals.

Cook dinner at home

Eating out can be expensive ­- especially if you want to eat healthily. Did you know that Americans now spend 50% of their food budget eating out? Cook at home with real food instead. You will eat healthier, skip the extra drinks, desserts, and coffees, and save a lot of money.

Cook simple meals

Simplicity is the key to healthy cheap meals. Each low-carb meal should have some good protein, non­starchy vegetables and plenty of healthy fats.

Meals don’t have to be complicated, in fact, simple meals are easier to make, cheaper, and will encourage you to cook more often.

1.4 Eat

Eat more fat

Add more healthy fats to your low-carb meals and you won’t want to eat so much. Once you become fat-adapted your appetite reduces and so does your meal size. Healthy fats at each meal will keep you satiated and fuller for longer.

Add plenty of cheese and herbed butter to your steak, olive oil on your salad, and coconut cream to your yogurt and you will only eat a portion of an equivalent low-fat meal.

Eat more eggs

Consider adding more eggs to your diet. Eggs are a great source of protein, fats, and other nutrients. They are a relatively inexpensive protein source, much cheaper than meat for example. Oh, and eggs are delicious – just check out our awesome recipes! By the way, the old saying that eggs are bad for us isn’t true anymore.

Fast intermittently

Once you eat low carb you will eat less, in fact, you will start to intermittently fast sometimes without realising. When you eat low carb, your appetite is under control and you no longer eat the volume of food you once did.

Planned intermittent fasting provides numerous health benefits and allows you to eat less and save more money.

2. What to stop doing

what to stop doing

Stop snacking

Snacks are unnecessary and expensive. Snacks will easily add up to a fourth meal. If you snack often, think about the meals you are eating. If you are still hungry between meals, maybe you need to add more healthy fats to keep you fuller for longer?

Are you eating out of habit? Boredom? When you eat low­-carb full-fat meals, hunger will be reduced and you often can avoid snacking altogether.

Stop wasting food

When you plan meals ahead, think about what you are buying and when it will be eaten. An average household throws away approximately 25% of the food and drinks it purchases.

Stop wasting food, stop impulse purchasing, stop throwing away ugly or misshapen produce, stop throwing away leftovers.

Look in your fridge and cupboards before you go shopping and cook the food that will expire first. Save even small amounts of leftover vegetables and add them in a frittata or soups.

Stop buying drinks

Drinks soon add up each week, so instead of buying expensive special coffees, make coffee at home or work with full­ fat cream.

Stop buying diet drinks, smoothies, juices, and bottled water. Instead, start drinking tap water and save big time. Or make flavoured water yourself by adding a squeeze of lime juice, berries or mint leaves for a fresh natural refreshing drink. There are endless options on how to flavour water.

Avoid temptation

Consider buying your groceries online to avoid temptations in store. When you are at the supermarket, avoid the aisles that have temptations such as confectionery, snacks and the bakery.

Don’t visit the supermarket when you’re hungry. This will help you to avoid impulse purchases. Try it, It works!

This is a tough one, but you may want to avoid visiting with your children. Pester power (the nag factor), product placement at children’s eye level and advertising directly aimed at children is well known to increase your spending. Shopping without kids will likely be cheaper and quicker.

Alternatively, when shopping with children, avoid the aisles with temptations and shop the perimeter instead. Take the opportunity to teach your children about making good choices and simple budgeting skills. Say no and be firm. Children have a sixth sense to discover your weakness.

Stop buying lunch – bring leftovers

Buying lunch every day is incredibly expensive. Invest just a few minutes each morning to make your own.

Add cold roast meat to a huge low­-carb salad, add cheese and olive oil and you have a wonderful cheap healthy meal.

Go for a walk in your lunch hour and eat your nutritious low-carb dinner from last night.

Stop buying processed food

Processed food is expensive and usually contain added sugar. Stop paying the price for convenience and start cooking at home to start saving money.

Stop buying ready-to-cook vegetables, and wash or peel them yourself. It only takes a few extra minutes.

3. How much money could you save?

Long term savings of low carb living

By eating low carb you will clearly spend less at the dentist and likely less at the pharmacy. You will probably have smaller medical bills and health insurance premiums might even be cheaper.

It is not uncommon for medication to be reduced or even stopped when following a low-carb lifestyle, e.g. when reversing type 2 diabetes.

Finally, there’s no price on living a healthy lifestyle that can result in weight loss, stable moods, reduction of risk factors of most modern diseases, improved insulin sensitivity, better blood sugar control, decreased pain and inflammation and the result of all that, simply feeling good.
