Reducing Costs on the Low Carb Keto Lifestyle: Part 3

This is the last of three conversations on Lessons from the Ketoverse about eating this way without draining your bank account. Parts one [link] and two [link] covered the hidden spending nobody counts, cheap cuts turned gourmet, bulk buying and more. You can read them in any order.

Here are the final five, including the one that surprises people most: the cheapest aisle in the grocery store is the one nobody walks down.

1. Skip the packaged keto products

Walk into almost any grocery store now, and you will find freezer doors and shelves dedicated to keto snacks and treats. Look closely at them and something becomes obvious: many are not much better than the food we already know is doing us harm.

The trouble is the ingredient list. Keto is a marketing word on the front of a box. It has nothing to say about seed oils, emulsifiers, sweeteners or the rest of the chemistry on the back. A product can be technically low carb and still be inflammatory, which is a distinction the packaging will never make for you. Sunflower, canola and palm oil turn up constantly in these products, and they are the first thing we look for. On sweeteners, we would just say be moderate; one of us keeps kombucha as an occasional treat for the fizz rather than a daily habit, because some of the research on the newer sweeteners has raised enough questions that moderation seems wise while the science works itself out.

There is also the word snack itself. Unless it came out of your own kitchen, a snack is usually the thing you are trying to leave behind. If you want something between meals, plain yogurt or a small handful of the better nuts will serve you far better than anything in a shiny wrapper.

One of us spent years following the front of the label and feeling steadily worse. The classic example: margarine is better than butter, so choose the margarine made with olive oil, because that must be the healthy one. Pick up that tub and read the back. Olive oil is near the bottom of the list. Canola oil is first, which means it is the main ingredient.

This is the real frustration behind the cost question. There are talented people employed full time to make food as easy to overeat as possible, and to make the box look like a health decision. Nobody is employed to make beef more addictive. It is just beef.

The defence is not willpower; it is literacy. Learn the handful of ingredients you want to avoid, and the whole store simplifies. Once you know that starch becomes glucose quickly, that maltodextrin is not a health food, and what the seed oils are, you can pick up almost anything in the middle aisles, glance at the back, and put it straight back down. It is genuinely satisfying. Eventually you find yourself shopping the outside ring with a couple of exceptions, like a good jar of olives, and the noise just stops.

2. Prep in batches

This one took one of us a long time to get good at, and honestly the skill was never cooking, it was planning. He was excellent at following the instructions on a package and putting it in the microwave for ninety seconds. That was the problem.

What changed was working out which ingredients he actually wanted in his body, then building a small rotation of meals around them. One example, a dish he calls beef au gratin: ground beef, eggs, half and half, and real parmesan, the hard fermented kind from Italy. Four ingredients. It comes out looking like shepherd's pie without the potatoes; it is remarkably filling, and one batch makes five or six meals. The only real risk is that the family finds it first, which is a good problem to have.

Meatloaf is the same idea: beef, eggs, a couple of whole ingredients. It does not look like the picture on the box, and it is far better than the box.

The point is what those batches buy you: fast food that is actually good for you. When the day compresses, and you need to eat in five minutes before you run out the door, you have something ready that you are glad to eat, instead of something you will regret. On a per-meal basis, it costs a couple of dollars.

There is variety in it too. Homemade yogurt, which we covered in Part 2 [link], keeps two weeks at a time. A big pot of chilli in the pressure cooker lasts forever, and freezing half of it means that in three weeks you open the freezer and find a gift from your past self.

One life hack worth passing on, with no affiliation of any kind: apps like Pestle let you scale a recipe from one ingredient. If you have two pounds of beef this week instead of a pound and a half, tell the app, and it adjusts everything else. No trimming meat to fit a recipe, no guessing, same result every time.

If "I don't have time" is forming in your head right now, we made the case in Part 2 [link] for rewording that to "it is not a priority for me right now," and doing the arithmetic on what the trade is actually worth. Start with once a month if you like. What you will notice is that it gets into a rhythm, and food stops being a stressor and becomes one less thing to think about.

3. Eat in a window

Part 1 made the cost case for this: fewer meals cost less money, and two a day instead of three plus snacks cuts that budget line substantially. So we will not repeat the arithmetic. What follows is the part people actually need, which is how you get there and where the pitfalls are.

One of us came to this the hard way. Nine years ago he was eating a vegetarian diet built almost entirely on starch, spiking his blood sugar, chronically low in B12 and magnesium, and getting sicker. Fasting was where he started, learned largely from the Canadian nephrologist Dr. Jason Fung, whose central insight is that the body needs a rest in order to heal. Over roughly seventeen months, he went from 232 pounds to 178, and his A1C trend came down year after year. His numbers have improved further recently, and he will share the details of what changed in a future episode.

The other of us eats his last meal around six and often does not eat again until noon. Not through discipline, just because he is not hungry. That is what a properly satiating dinner does.

A few honest cautions, because this is the section where people get themselves into trouble. Expect a rough patch early on, the so-called keto flu, as your body switches from running on glucose to running on fat; it passes. Stay hydrated, and pay attention to sodium and potassium. Talk with your doctor before you start, particularly if you take medication for blood sugar or blood pressure, since doses sometimes need adjusting.

And the multi-day fasts are a different sport entirely. Coming out of one badly, with a burger and fries and a milkshake, undoes the work and can leave your system struggling for days. That is not a beginner's move, and it needs real research and medical guidance. What we are describing here is much simpler: eat two good meals inside a sensible window, and stop grazing. Kindergarten before university.

4. Stop throwing food away

Here is a cost nobody budgets for: the food you buy and then bin.

Part of why ultra-processed food feels convenient is that it does not rot. A box of cereal will sit in the cupboard for a month without a thought. Whole foods are the opposite; they all go bad, some of them quickly, and that creates a low-grade stress where everything in the fridge needs a tactical plan.

The fix that worked in one of our kitchens was vacuum sealing, specifically the glass containers with a rechargeable vacuum pump rather than the plastic bags. Food that would normally last three days routinely goes thirteen or fourteen. Leftover meat, that meatloaf, cut vegetables: sealed, they easily last a week and a half. The reason is simple enough: less air in the container means less for bacteria to work with.

You do still need some organization, since a fridge full of sealed containers you cannot identify defeats the purpose. But glass helps, because you can see what is in there. And every container you do not throw out is money you already spent, kept.

5. Rediscover the cheapest aisle in the store

Our favourite of the whole series. Walk to the aisle with the canned fish. Notice something: there is nobody there. You can stretch your arms out. Everyone avoids it.

Sardines are extraordinary food. They are a small fish, so you avoid the heavy metal accumulation that comes with the big ones. They are one of the best sources on the planet of the omega-3s that matter, DHA and EPA, which support your brain and the rest of your body, respectively. And they cost a fraction of what the snack aisle charges.

If sardines sound revolting to you, you are in the majority, and there are ways around it. Mash a tin with a good mustard, and it turns into something else entirely. Blend them with eggs and a couple of things you like, fry little cakes out of them, and you have a superfood that no longer looks like fish. Serve those to your family, and nobody will ask questions. Dr. Ken Berry, one of the voices we featured in our influencers episode [link], has covered this well recently if you want to go deeper.

The same logic applies down the rest of that aisle. Canned salmon and tuna. Even the foods that got labelled uncool: one of us grew up lower middle class, eating spam, salmon, tuna and head cheese, was an elite athlete throughout, and did just fine. We would still say read the labels rather than take anything on faith, because these products vary and some carry sugar and starch you might not expect. But compared to a bag of chips, it is not a close contest.

Hot dogs deserve the same treatment: read the ingredients, put back the sugary ones, and consider going to the butcher instead, where the ones made from properly ground nose-to-tail beef are a different product entirely.

And ground beef, which might be the most underrated food in the store. One of us assumed for years that cheap meant inferior: ground beef at seven or eight dollars a pound against a steak at twenty or thirty. But the reason ground beef is cheap is that it is made from the gristly, connective tissue-heavy cuts nobody wants to chew. Look up what connective tissue actually contains. There is an argument that you are getting more of what your body wants from good ground beef than from the expensive steak, and paying a third of the price for it.

The summit view

That was the point of all three parts. When someone tells you they cannot afford to eat this way, you now know something they do not. It can genuinely cost less than what they were eating before.

You will still have to walk it yourself. You will buy a gadget that you abandon in three weeks and feel silly about it. That happens to everyone. But nine times out of ten you end up somewhere that costs less than where you started, and you feel dramatically better for it. It is hard to put a price on that.

If you would like a guide who has already spent the money on the wrong gadgets, that is what we do at Ascent. You are the climber. We carry the map.
