8 things to avoid on a keto diet

There are many guides telling you what to eat and drink on a keto diet. It can however sometimes be good to also know what to not eat or drink on a keto diet. Since that food that are good for a keto diet are foods that are very high in fat and low on carbohydrates the opposite should therefor in general be avoided.

Diet soda

Diet soda might seem like something that is good to drink at a low carb diet since they do not contain any sugar or carbs. However there is a danger with these and that is the artificial sweeteners that are used as replacement for the sugar. Everyone’s bodies react differently to these sugar substitutes. Some people can drink diet soda without any problem when on a keto diet and others can not have a single glass of it without interrupting their diet and their ketosis.

Low-carb sweets

There are many different low carb sweets out there that claim they are good for a low carb diet. However most of these often contain processed food and also in many cases a relative high amount of carbohydrates. It does not seem like a lot when it says 4 net grams of carbs but if you eat 2 or 3 of these candy in one day it quickly becomes quite many carbohydrates.

Most vegetables that grow below the earth are very high on carbohydrates. Examples are carrots, onion, potatoes and you should avoid these when on a keto diet. You should also consider removed celeriac, pepper (the sweet and red ones), tomato, peas from your meals.


Grains and food that are made from grains should be completely avoided. This includes bread, cakes, pastries, pasta or anything that is made from flour. You should also avoid foods that contain battered coating or breadcrumbs. The same applies for rice.


Since alcohol usually does not contain any carbohydrates it might seem that it is okay to drink alcohol. However you need to take into consideration that alcohol is a fuel and therefor will be the first thing your body will try to burn. This will put the fat burning process on a hold or greatly slow it down. If absolutely need to drink alcohol on certain occasions try to drink straight liquors such as vodka, scotch or gin instead of alcohol that also contain sugar.
