Ketogenic Diet Foods to Avoid

by

I see a ketogenic diet as a lifestyle and I would have liked to say that there are no foods to avoid on a ketogenic diet. In an ideal world I would have told you to eat any food, but just eat all foods in moderation. That is kind of what we are told all the time. Isn't it? 🙁

The reality though is that there are plenty of foods that we should never have eaten in the first place and now to just say eat them all in moderation is therefore not a valid or useful argument.

Whilst on a ketogenic diet the foods to avoid can be summarized as all sugary and starchy food. This is a topic I intend to cover only once, as I prefer to focus on what we should be eating and doing, rather than what we shouldn't be. If you feel the same and want to rather check out what you should be eating, then check out our list for a comprehensive shopping list and our ketogenic diet checklist that summarizes it all.

Now, let's look into the different categories of food we shouldn't be eating and why.

What About Fruit?

Rather than list all the fruits that we shouldn't be eating on a low carb diet. Check out the list of the fruits we can eat here...

Not being able to eat most fruits makes me somewhat sad, but when I focus on how well I feel when my insulin levels are under control, I really am okay with it. I do have the occasional fruit, maybe an apple or a kiwi fruit.

I have cut down completely on my fruit intake, except for berries and lemon, but occasionally I have a strong craving for bananas. When this happens I have them. I know I can also look for a different source of potassium, but I feel strongly that a keto lifestyle requires me to listen to my body and that when my body tells me strongly that I need something I listen.

These cravings are different to the out of control cravings I used to have when I fueled my body with sugar and starchy carbs.

If I had to go on a starch binge tomorrow and have cravings after that, I will know what they are. They are very different to my body's real need for a nutrient that I may have neglected.

One of the big benefits of removing these highly addictive foods from my diet, is that I no longer have out of control cravings.

Dairy

Dairy is allowed on keto. But it is mostly cream, butter and some cheeses. Always make sure that they are full cream.

Keto diet what not to eat
  • Flavored milks and yogurts
  • ​Low fat or skimmed milk and yogurt
  • Milk or yogurt with added sugars or sweeteners
  • Ice cream
  • Cottage cheese
  • Full cream milk (Limit because of natural sugar content

Packaged and Processed Snacks

Who doesn't love popcorn? And now that we know we should bee eating butter, it sounds really tempting to have popcorn with lots of butter. But off course butter is only good for us when it is not eaten with carbs. So let's have a look at what snacks to avoid on a ketogenic diet.

  • Popcorn
  • Pretzels
  • Potato and tortilla chips
  • Rice cakes
  • Flavored and coated nuts
  • Cheesy and flavored crackers
  • Granola and breakfast bars
  • Protein bars
  • Any boxed or packaged snacks

  1. I love how it makes me feel, I’m excited and hyper all day long. I can’t shut up. I’m a type 2 diabetic, my sugar stays at 169 and below so if I take my medicine I’ll bottom out, so I pay very close attention to what I eat.

    • Hi Mary, thank you for sharing your experience with us. I am so happy that Keto is working for you. Stay healthy…

  2. Why avoid diet drinks if they have no calories or sugar? What about sugar-free chewing gum… is it allowed in the Keto diet?

    • There are 2 schools of thought on artificial sweeteners.

      Personally I am in the no camp especially when it comes to artificial sweeteners like aspartame. There are way too many studies showing how bad it is. It also tends to make me hungry. For me one of the biggest advantages of keto is that I am not constantly hungry.

      My experience with chewing gum is that it also makes me hungry. It creates the impression in my brain that it is time to eat.

      For me personally it is more about the quality of my food rather than the calories. I do still use sugar alcohols like xylitol in my baking, but I am working on limiting them.

      The other school of thought focus on calories and have no problem adding sugar free gum and zero calorie drinks. Lots of people have these Zevia Zero drinks.

      The keto diet is very individual. The best is to follow the basic guidelines, but work out what works best for you and adapt as you need to.

      Hope that helps…
