Typically, that source is a person’s carbohydrate intake, which is converted into glucose and absorbed into the bloodstream. Because remaining in ketosis requires such strict discipline, many find it difficult to maintain the regimen long term. And the longer one stays on the diet, the greater the risk of nutrient deficiencies. The nutrient ratios may trigger other problems, and the diet’s precision can also set the stage for disordered eating in vulnerable individuals.

Certain foods are not recommended on the ketogenic diet as they are too high in carbohydrates. Apart from being rich in B vitamins and potassium, these foods are also quite low in carbohydrates. A fat intake around 70% of total calories may be a good choice for some people on low-carb or ketogenic diets. A ketogenic diet can be used to achieve weight loss, blood sugar control and other health-related goals.
