There are many low-carb ingredients that you should avoid in ketosis due to many reasons. I will be discussing them in detail down below.

Sometimes when people start ketosis, they believe that anything that is low-carb is fit for them to consume in any amount they seem fit. Well, that is totally and entirely wrong. There are certain foods that you should avoid at all costs so that your ketosis stays healthy.

While in the market, you will see many food products with details that describe them as purely healthy to consume. Well, do not be tricked easily. If it is low-carb, it does not means it is going to be healthy.

Low Carb Food To Avoid On The Keto Diet

I am not going to take you through a long and exhausting alphabetical list of low-carb items that you should avoid. I have put my time in getting all the items into categories so that you save time while going through them. Let us get right at it.

The following list has a categorical division of low-carb foods that you should avoid.

  • Seed oils and vegetable oils (processed)
  • Soy products
  • Dairy products
  • Low-carb desserts
  • Energy bars
  • Any processed food
  • Diet sodas
  • Artificial sweeteners

Let us start their detailed breakdown for a better understanding.


The Oils

The first thing on the list is the processed oils from seeds and vegetables.

Stop consuming anything that has been cooked in the following oils.

Eliminate anything cooked with the following oils if at all possible:

  • Vegetable Oil
  • Sunflower Oil
  • Soybean Oil
  • Cottonseed Oil
  • Corn Oil
  • Safflower Oil
  • Canola Oil

Now that we know which oils to avoid, let us see why they should be avoided.


They Have Unstable Fats Which Go Bad Easily

Here is a fact about these oils. They go bad very quickly and they have rancid fats with a very short shelf life. Amazingly, these oils spend years on the shelves. When you cook food in them, the heat further oxidizes them and that is not good news for your body because the common rebuttal here is inflammation and toxicity spike in cells.


Excessive Omega-6 Intake

Humans have been increasingly consuming omega-6 as compared to omega-3 in our daily food. We should know that there is a huge amount of omega-6 in seeds and vegetable oils which is not properly balanced with omega-3 and that is pretty dangerous for our health.

If the intake is continued, bad outcomes are sure to be observed which include obesity, cardiovascular diseases, risk of cancer, DNA damage, and metabolic diseases among others.


in order to deal with this dilemma, you have some pretty tasty alternative oils like avocado oil, olive oil, ghee, or coconut oil. You can also consider bacon grease, duck fat, and lard as well.


Artificial Sweeteners

You should keep this fact in mind.

“Artificial sweeteners are nothing by carbs.”

There is a large range of artificial sweeteners that you see out there in the market. So you need to make sure that you know which are healthy and which are not.

Here is the bad list.

  • Saccharin (Sweet ‘N Low)
  • Acesulfame (ACE K)
  • Sucralose (Splenda)
  • Aspartame (Equal, NutraSweet)

These sweeteners are mostly used in gum, sugar-free candy and diet drinks.




Stevia is a white powder sometimes mixed with some liquids. It is extracted from a plant and is totally harmless for the human body. It even helps in controlling lower blood pressure.


Sugar Alcohols

Sugar alcohols are considered to be better than artificial sweeteners because of them being natural. However, their low absorption by the large intestine makes them a problem for the digestive system.

The main sugar alcohols that you can avoid are:

  • Sorbitol
  • Xylitol
  • Maltitol
  • Lactitol
  • Isomalt
  • Glycerol

Another alternative here is erythritol which causes no digestive disruption. It has low calories and works well in baked goods.


Diet Sodas

With about 40 grams of carbohydrates in a single can, regular sodas are completely poisonous for ketosis. But you can confidently enjoy a diet soda or a diet coke because they have zero carbs.

Now you might question if they have no carbs, then why am I forbidding to use them?
well, they are full of artificial sweeteners. So there’s that.

Processed Foods (Energy Bars And Low-Carb Desserts)

Most of the bagged or boxed food has been found to be not good for keto. Be it ice-cream, brad, or anything with a claim to be healthy.


Energy Bars

Many energy bars have different additives, artificial sweeteners, and vegetable oils which are not keto-friendly. They also have an addiction problem so you might overeat them. Plus their effect on ketone levels is also unknown.

Test your ketone levels using these ketone urine strips.


Low-Carb Desserts

Desserts with low-carb ingredients are fine to be used but only occasionally. The problem with them is that they can get you easily addicted and exceed your limits.


Dairy Products

Although dairy products have been found to be not a threat to keto diets, yet they have 2 main characteristics that make them land in the grey area.

First is that you can overeat them. Their nature and smoothness can be overwhelming and you might end up destroying your long struggle of ketosis.

Second is that they contain lactose and casein. These two are sometimes quite troublesome and can cause joint issues, acne, inflammation, and many more. You can use dairy products for healthy food, but I would recommend you skip them in ketosis.



Here are some awesome replacements.

Cashew cheese for regular cheese

Almond milk or coconut milk for regular milk

Coconut oil for butter


Soy Products

Soy products may seem like a good low carb alternative, but there are 3 problems with soy:

Although soy products are low-carb, the following 3 reasons cut them out of the flow.

  1. High estrogens – they have a huge amount of phytoestrogen that is responsible for disturbing your hormones.
  2. Highly processed – they have a lot of phytates which will deprive you of nutrients and bombard you with estrogens
  3. High phytates – they slow down the absorption process in your body

Here is the bad list for soy products

  • Soy-based meat substitutes
  • Soy-based dairy
  • Soy milk
  • Tofu

However, tamari sauce (fermented soy) is not bad to consume because the fermentation degrades phytic acid.


Get Dedicated For A Healthy Ketosis Diet

It is a common belief that only eating low-carb food is ketosis. Additional to this fact, having a healthy diet is equally important with long-lasting benefits in terms of weight loss.

Let us try to define a diet that is both keto and healthy

  • Natural foods with high nutrients
  • Stop using artificial sweeteners
  • Stop using processed foods
  • Stop using gluten
  • Eat whole food more

Now that you have been educated on what not eat in ketosis, let us talk about some things that will prove to be helpful to eat without restrictions of any kind.

Here is the good list

  • Eat organ meats
  • Enjoy fish
  • Have fun with meats
  • Devour low-carb fresh vegetables
  • Low-Carb Vegetables
  • Keto Supplements (totally optional)
  • Low-carb vegetables
  • Seafood

These items will supply minerals and essential vitamins to your body along with continuous ketosis.
