When pursuing keto diets, there is an emphasis on eating low carb foods for weight loss. keto diets do not prohibit the intake of carbs from one's diet completely. One is allowed to take some carbs although in small quantities. 

However, you just can't eat any carbohydrate foods you think of. There are carbs that are recommended for keto dieters. You can read keto recipe journals to get more information on keto diet.

The scale that determines the value of carbohydrates is known as the glycemic index. When you use this index, you will determine the foods to eat in a keto diet and the foods to avoid. 

The glycemic index ranks carbohydrates according to their glycemic load by giving each food points. The higher the glycemic load of a food item, the less it affects our blood sugar levels thereby helping to maintain a balance that helps prevent unwanted weight gain.

Foods that you must not include in a low carb diet are processed foods. Hence, don't eat processed food on the keto diet. The additives, chemicals and sugars contained in processed carbs affect the blood sugar negatively thereby promoting weight gain instead of weight loss. 

Low carb foods will help you achieve good health while maintaining your ideal weight.
