Keto has been an ongoing journey for us, and maybe you can relate. When we first started the keto diet, we couldn't believe how different we felt just by changing the foods we were putting in our bodies. We have spent the last three years going beyond low-carb, and we've researched even more ways we can optimize our health. There's more to food than just carbs, proteins, and fats. We now have 10 keto foods we avoid!
Listen to YOUR Body
We love self-experimentation. It's amazing what you can learn about yourself just by cutting out a single food group for a week, or paying more attention to any changes in your mood, digestion, and skin. To figure out what works for you, it's best to just try something new and find out for yourself. Check out all of our diet experiment videos.
- Prolonged Fasting
- 4000-Calorie Challenge
- Intermittent Fasting
- Cyclical Keto
- Deeper State Keto
- Egg Fast
- Carnivore
After years of trial and error, we now have a list of 10 keto foods we avoid. This list has grown and changed over the years and we're certain it will continue to evolve as we learn more about our ever-changing bodies.
Please Note: The following foods are specific to our bodies. These foods are fine for a keto diet and this is not a list you need to abide by, but hopefully you can learn something from our experience!
10 Keto Foods We Avoid
1. Traditional Mayonnaise
Mayo is definitely a keto-friendly food, but that doesn't mean it wears a "health halo".
We have completely cut soybean-based mayo from our diet since learning about the harmful effects refined vegetable oil has on the body - number one being increased inflammation.
Megha loves mayonnaise, so she finds brands that use avocado oil and coconut oil instead of canola oil, sunflower oil, and soybean oil. For more information on refined vegetable oils, check out our blog post about Healthy Cooking Oils.

2. Chicken - It's Just Not Fatty Enough
Occasionally, we enjoy a smoked chicken or a pound of wings on date night, but to tell you the truth, we don't eat much chicken. Here are some reasons why we avoid chicken.
- Chicken is incredibly lean in comparison to red meat and fish. It's difficult to hit our fat macros when we eat chicken as a meal.
- Chicken is higher in Omega-6, which can lead to increased inflammation, while fatty fish contains high amounts of beneficial Omega-3 fatty acids.
- Red meat and fatty fish are more nutritionally dense.
If we are going to have chicken, we prefer to have chicken thighs for their higher fat content. Try any of our chicken recipes on the blog, a few of our favorites are Butter Chicken and Mexican Shredded Chicken.

3. Sugar-Free Candies - They Spike Blood Sugar
Most sugar-free candies are technically not sugar-free. If you read the ingredient label, you will most likely find the candy is sweetened with maltitol. Maltitol spikes blood almost as much as regular white sugar, making it not keto-friendly at all.
Watch our Sweetener Testing Video where we test out all the low-carb sweeteners and reveal which ones actually are not low-carb.

4. Swapping Pasteurized Dairy for Raw
The majority of dairy products in the grocery store are pasteurized, which means the milk was heated to high temperatures in order to kill off all of the natural bacteria.
We prefer unpasteurized, raw milk products that still contain all the natural bacteria, delicious flavor, and notable textures. Sure, we will occasionally have a little pasteurized cream in our coffee, but we will never go back to buying cheap, pre-shredded cheese in a bag. Raw milk cheese is just too delicious! We are hooked.

5. Cutting Back on Coffee
On average, Americans consume 3.2 cups of coffee per day, and let's not forget caffeine is a drug. It can increase anxiety, heart rate, and the withdrawal symptoms are real. Cutting back on caffeine has been difficult, but highly rewarding. We no longer have coffee on the weekends, which doesn't sound like much of a change, but after two days without coffee, that Monday morning cup of joe is amazing.
Coffee is no longer something we need to function. Instead, we view caffeine as a tool we use to have better workouts and be more productive at work.
We encourage you to try this method out for a week. We would love to hear how using coffee as a tool effects you!

6. Store-Bought Salad Dressings
More and more studies are coming out all the time showing the ill effects of refined vegetable oils on human health. We like to avoid anything that contains canola oil, soybean oil, or sunflower oil, so we avoid store-bought salad dressings.
There are healthier alternatives out there. Read the ingredient label and look for products made with avocado oil, or you can make your own salad dressings at home using extra virgin olive oil and vinegar.

7. IMO Fiber - Isomaltooligosaccharide
IMO Fiber was originally thought to be completely undigested, making it the perfect low-carb ingredient in store-bought keto treats, but when tested, it was found to be partially digested by the human body.
IMO Fiber scores a 35 on the Glycemic Index, which is the same as drinking chocolate milk or eating a bagel! On top of its high glycemic load, it is usually accompanied by insulin-spiking Maltitol. This duo is delicious, but not okay on a keto diet. Chances are, if it tastes, looks, and feels like a candy bar, it probably contains IMO fiber and maltitol. Read the ingredient label!

8. Berries
Neither of us have ever been big fans of berries. Many people eat berries for their antioxidants, but we find the sugar load is too high for the small amount of micro nutrients we can get from a handful of berries.
The more research we do, we are discovering the bio availability of any nutrients from plant foods is a lot lower than animal foods. Just because a blackberry contains a certain level of antioxidants, doesn't necessarily mean our body can convert them into usable nutrients.
This is just our personal preference. Berries are keto-friendly and are a great alternative to regular candy!

9. Nuts - Too Delicious!
Nuts are crunchy, salty, and fatty, making them delicious, but difficult for us to eat in moderation. Nuts are also high in Omega-6, which we're trying to reduce in our diets.
If you find a food addictive, even a keto food, chances are you're going to overeat and hinder your progress. If you want to include nuts in your keto diet, we recommend sticking to low-carb nuts like macadamia and pecans, and portioning out small bags, so you don't end up three cups of almonds!

10. Veggies
After experimenting with our veggie intake, we have found we feel best without them.
Megha knows cauliflower gives her gas, discomfort, and makes her feel bloated, so she avoids it. Digestion discomfort from vegetables is not uncommon. There are a number of sugars in vegetables called FODMAPS that many people have trouble digesting. Check out Dr. Paul Mason's talk on vegetables and gut health.
If we are craving a salad or some grilled asparagus, we will enjoy some veggies, but we no longer go out of our way to fill our plates with fibrous greens. We focus on consuming high quality animal foods like red meat, salt water fish, and eggs.

In Summary
We highly encourage self experimenting to figure out what works best for you! Over the years, we have done just that. This list has changed throughout the years and will continue to change in years to come, but for now, these are the 10 keto foods that we avoid!
1. Traditional Mayonnaise
2. Chicken
3. Sugar Free Candies
4. Swapping Pasteurized Dairy for Raw
5. Cutting Back on the Coffee
6. Store-Bought Salad Dressings
7. IMO Fiber
8. Berries
9. Nuts
10. Certain Veggies

The veggie part is so confusing to me! How are you getting fiber? Just from your coconut wraps and coffee? Veggies are so good for you! Please elaborate!
Now I see why your recipes (and frankly, your complexions) look so beige-grey: No veggies or fruits. God forbid you incorporate color into your diet. Disgusting lifestyle and incredibly irresponsible to be preaching this sort of high-fat, dirty-ketoing to your ‘fans’.
Your clearly have no educated concept on what intelligent ‘ketoing’ is all about, nor the fact that being in ketosis is not supposed to be a permanent state. ‘Sickening.
Matt & Megha still eat vegetables 🙂
I have been on the keto diet for 3 months and have lost 12.5 lbs. I feel like I could be loosing a little faster. Is this a normal weight loss for keto? Also, one other concern of mine is that I love my coffee. I don’t use sweetener but I have been using the powder non dairy creamer. Is this ok on a keto diet?
Any food is okay on a keto diet as long as you are limiting your carbs to around 20 grams of net carbs per day. If you wanted to incorporate something that is higher carb, just eat less of it and track it in your carbs so you don’t over-eat carbs.
Hi! I’m from the Netherlands and we only seem to have mayo based on canola sunflower or soy (Soy is also uncommon btw). oils. I Will continue my search 😉
Thanks for the usefull info!
Did you know that veggies actually do NOT want to be eaten so they fight back with toxins? Since they cannot run away to keep from being eaten. LOL

I was stunned to first hear this. I am more on a carnivore-type diet now anyway. I DO want to try your egg fast. I’ll never get tired of eggs and cheese! Nope.
I am doing a long fast right now. I’m 68 hours in and feel perfectly normal. Just drinking zero calorie liquids. Not sure when I am going to cut it off. Trying for maximum autophagy. I am 60 and have been 100 pounds overweight for 35 years. So naturally I am having saggy skin. Keto on, my friends! Love you guys!

Love this couple. Am new to the keto diet and still learning but feel great so far. I’ve lost 3lbs in a week and am happy with that as all I did was cut out ‘obvious’ carb (looking for a total 20lbs weight loss). Not that I’d like to taper things down even more to actually be on a ketogenic diet, I find this channel extremely encouraging and helpful in setting me up for success!
I’m extremely interested in which products we are seeing Isomaltooligosaccharide? I have quite a few sweeteners and I’m unsure which ones are Isomaltooligosaccharide. Would you be able to private provide some brand names? Thank you.
Usually, IMOs are used in some low-carb packaged products, not sweeteners. They are in some low-carb protein bars. It should be on the label so just make sure you check the ingredients.
No veggies?? I love your site and recipes, but, NO VEGGIES!! Come on…….
As always, I enjoy reading your blogs and trying out your recipes. In fact, tonight I’m going to make the deep dish pizza recipe for the first time. I doubt i could cut out many of the items you listed above – but definitely agree on the sugar free candies. When I was first diagnosed with Type 2 diabetes, I thought I could eat the sugar free candies instead of regular candy. Nope. My sweet tooth is now appeased by your peanut butter cookies, or I like to make a chocolate shake with macadamia milk, unsweetened cocoa powder, HWC and Truvia. I also don’t eat any fruit regularly, but I will occasionally enjoy a handful of blackberries, or a slice of plum or fresh peach in season. Giving up coffee – no, but I have one cup in the morning and enjoy it very much. Other than that, I drink water, lots of water. Just want to say – I appreciate this blog and it’s been very helpful to me!
Can you recommend a healthy salad dressing? I love ranch and when I’m at a restaurant it’s my go to even though I know there are probably better choices. I have been doing my best to follow at Keto diet since March and am down 24 pounds and I feel wonderful! I love your podcast and your website! I have your cookbook and your fatbomb bible! Thank you for your positivity and keeping us up to date on the lastest Keto trends!
I am curious to know about how you guys maintain…uhh…your motility…i guess. Sorry. You don’t have to go into detail or anything. Sorry again.
I think this is when Jamie Lee Curtis is supposed to walk in like we hang out all the time and make me feel less bashful about poo.

Drinking water, eating vegetables for fiber, and exercising help. Also, you can use MCT oil if you are having problems. Maybe about 1 tablespoon? it usually makes you go to the bathroom within a couple of hours haha. Coffee also has the same effect for many people.
I just want to applaud you guys for mentioning FODMAPs. I have suffered with Ulcerative Colitis since 2009. I felt better going gluten free shortly after diagnosis, even when my doctor insisted my issue was not food related. Fast forward a few years to a new doctor who finally listened to me; my UC symptoms were under control but I was still suffering with IBS. Knowing that I preferred to not take more medication and that I was one of the few patients that he had that would change their diet, he suggested a low FODMAPs diet. Within a week, my symptoms decreased. A year after doing the low FODMAPs elimination and reintroducing foods back in, I decided to give Keto a try. The two together have been amazing and I don’t remember the last time I’ve felt this good. My doctor says that I am in symptomatic remission!! Thank you for all that you do! When I decided to give Keto a try, you two were the first ones I followed and are still my go to. Love your cookbook and am looking forward to the next!!
Nah, I’ve always love the nuts, maybe the veggies when I was little but not now,
Re sweeteners: I have terrible diarrhea from all other sweeteners except Stevia, and that makes me not feel well. The only sweetener I can use is Splenda. It is not supposed to affect one’s glycemic index. So, I am stuck with this or nothing sweetened.
