Basically, any food that has a rich amount of carbs and unhealthy fats is not good to eat when you are following a keto diet. Let us have a glimpse of the foods that you must avoid to ensure you can stay into ketosis for longer:

Sugars

Any food that contains sugars in any form needs to be avoided. Carbohydrates can hamper the whole purpose of a keto diet as it prevents your body from believing that it is deprived of its primary source of fuel. So, it will not be tricked into burning fats as a source of energy. 

• High carb foods that are best avoided include:
• Cakes and pastries
• Fruit juices and soft drinks
• Fruits such as banana, grapes, and berries
• Ice cream
• Candies 

Unhealthy Fats

Foods that contain unhealthy fats like trans and saturated fats can work against the purpose of a keto diet. These fats can increase your cholesterol and triglyceride levels and worsen the risk of heart diseases. 

This is why; keto dieters should avoid using hydrogenated and partially hydrogenated oils in cooking. They can, instead, use healthy oils like olive oil or coconut oil. Junk foods and fried foods like fries, chips, and burgers also contain unhealthy fats and hence, must be avoided.

Artificial Sweeteners

Beware of any foods that have artificial sweeteners. These foods usually contain Saccharin, Aspartame, Cyclamates, and Sucralose that could cause significant harm to the body tissues when consumed regularly. If you must add a sweetener to your dishes, try using honey or stevia.

Seed-oils

Some seed oils contain unhealthy fats like omega 6 fatty acids. They include:

• Soybean oil
• Cottonseed oil
• Grapeseed oil
• Sunflower oil 
• Canola oils

Minimize the intake of these oils to prevent stalling while on a keto diet. 

These foods can take you away from your fitness goals. If you want to achieve ketosis or stay into ketosis for longer, make sure these foods find no entry into your body, or even better, not into your house.
