The Best Keto Diet Foods to Avoid

keto diet foods to avoid

A simple, clear and easy to read list of keto diet foods to avoid is now available in the popular, handy and convenient Bad Keto Diet Books for all your Keto diet food shopping and meal planning. The first category is “Fats”. Fats can be unsaturated or saturated fat. Foods to avoid include hydrogenated oils, trans-fatty acids, vegetable fats, corn syrup solids, etc.

Dairy: This includes all milk products including cheese, ice cream, yogurt, butter, yoghurt, and other dairy products. Unsaturated fats are better for your health, particularly those that come from plants like nuts and seeds. Unsaturated fats come from avocados, hemp oil, coconut oil, olive oil and other healthy plant oils. You should also avoid hydrogenated fats and processed dairy. In general, dairy products are high in lactose, which is a sugar that converts into cholesterol when consumed in excess.

All fruits contain significant amounts of fructose (fructose is a type of sugar that is used for energy by the body). When consuming fruit juices or eating fruit itself, it’s always best to choose organic or fruit juices without added sugar. Also, when purchasing or preparing any diet menu items, it’s always best to purchase frozen or canned fruits.

All grains contain carbs (carbs are fuel) and are an important part of a healthy diet. When purchasing or preparing any keto foods, it’s always best to purchase unprocessed grains such as flaxseed, brown rice, etc. Other than that, fruits and vegetables are your main source of carbohydrates and fortunately, they are available in a variety of colors, tastes and varieties.


All fat is bad for weight loss. Even though some fat is necessary and some is good for health, excess fat intake will result in excessive weight gain. As a general rule, the more saturated fat you eat, the more likely you’ll be to gain weight. So, it’s really important to watch out for fat.

Processed Foods

Most processed foods are heavily laden with sugar. If you want to lose weight, you’re better off avoiding white flour products, packaged foods (packed in plastic), refined sugars, etc. When preparing or buying most processed foods, look for the Nutrition Facts (or ingredients label) to determine how much of each ingredient there is. Unfortunately, even with the labels, the amount of sugar may not necessarily be listed.

Fruits and Vegetables

A keto diet should emphasize eating lots of natural, unprocessed fruits and vegetables. Avoid eating too many potatoes, especially starchy ones (such as French fries and potatoes with fat), fruits that have a high sugar content, like bananas and pineapple, as well as overly sweet fruits, such as apples and melons. Many fruits and vegetables contain natural sweetness, so you don’t need to avoid them altogether. Instead, focus your eating on leafy green vegetables, raw vegetables, fruit with a low sugar content, and raw fruits.

Fruit Juices

Some people mistakenly think that just because fruits have a low sugar content that they are safe to include in a keto diet. However, not all fruits are created equal. Some fruits are highly processed before being added to the juice, while others are very natural, full of nutrients, and full of sugar. It’s best to choose organic, green juice if you can, because the juice will have a lower amount of sugar.

Fast Foods

The types of fast foods that should be avoided on this diet are anything with a high amount of refined sugars. This includes pastries, cookies, crackers, doughnuts, candy bars, and other sweets that have high sugar. Instead, you should focus your eating on lean proteins, healthy fats, and whole grains. You should also keep in mind that refined sugars can be problematic, especially in regards to children and diabetics. Therefore, it is important to research the ingredients in your foods so that you can choose healthy alternatives.


All oils, whether from plants or animals, are not good for a keto diet. Instead of focusing on oils, focus on fats. Plant-based oils are good, as long as they are monounsaturated (found in the sunflower seeds, olives and other healthy oils) or poly-saturated (found in nuts, olive oil and other healthy oils). Unrefined, hydrogenated oils are only bad for your health and should be avoided as much as possible.

Final Words

Fruits and Vegetables: Avoid all starchy carbohydrates such as breads, pastas, potatoes, rice, and cereals. Instead, focus on unrefined complex carbohydrates like fruits and vegetables. You should also limit your consumption of dairy products and processed foods. As much as possible, choose a variety of fruits and vegetables in your meals.
