- Carbohydrates increase blood sugar levels, which can cause dangerously high blood sugar in a diabetic. Eating a diet that is lower in simple carbs, such as white bread and sugar, is healthier for a diabetic. Lowering the effect of carbs on the blood sugar by eating them with fat and protein is recommended by the American Diabetic Association.
- The ketogenic diet, which reduces carbohydrate intake until the body begins to produce ketones, as an indicator that it has gone into ketosis, is used to treat epilepsy. Ketosis is a bodily process by which the body changes stored energy into available energy. Ketones are a byproduct of this process, and are excreted in the urine.
- When low-carb diets advocate substituting lower carb choices for higher carb choices, it can improve the diet. Whole-grain bread, for example, provides more nutrients and fiber than bread made with refined white flour, and is a lower-carb choice. Satisfying a sweet tooth with a handful of strawberries rather than a handful of candies is a low-carb choice that reduces fat and sugar and adds vitamin C to the diet
- An extremely low-carb diet, which eliminates all sources of carbohydrate, including bread, vegetables and fruits, may not be healthy. It is important to consult a doctor before making any drastic changes to your diet. A nutritionist can recommend a diet that is healthy for you, and contains all necessary nutrients.
- A moderate low-carb diet, undertaken under a physician's supervision, can provide many health benefits. Eliminating, or strictly limiting, sugars, junk foods and highly processed and refined foods is not unhealthy. Replacing these foods with green leafy vegetables and whole grains is suggested in moderate low-carb diets, and will provide the necessary nutrients for healthy living.
