Ketosis diets, also called low-carbohydrate or low-carb diets, promote carbohydrate restriction as a weight loss tool. Low-carb diets that restrict carbohydrates most severely promote ketosis -- a state in which substances called ketones build up in your blood and your body resorts to stored fat as energy in place of carbohydrates. According to MayoClinic.com, low-carb diets pose numerous risks as a diet based on fruits, vegetables and whole grains is the healthiest option.
Hyperuricemia
Ketosis can lead to excessive production of uric acid and hyperuricemia, represented by high uric acid levels. According to the Weight-Control Information Network, hyperuricemia increases your risk for kidney stones and gout -- a painful form of arthritis. High uric acid levels are also associated with high blood pressure, heart disease and kidney disease. Both kidney stones and gout can cause sudden, excruciating pain.
High Cholesterol
High cholesterol is a major risk factor for heart attacks, stroke, heart disease and certain forms of cancer. Low-carb diets that promote ketosis often allows ample intake of foods high in saturated fat and cholesterol, such as red meat, organ meats, poultry fat and high-fat cheese. Consuming a low-carb diet based upon these unhealthy fat sources increases your risk for high cholesterol significantly, according to MayoClinic.com. Frying your meats or adding butter, margarine, cheese or creamy sauces increases your risk for these complications. If you have family that has experienced heart disease or a personal history of this issue, your risks are further heightened.
Digestive Symptoms
Low-carb diets that cause ketosis are generally low in fiber-rich foods, such as whole grains, legumes, starchy vegetables and fruit. As a result, you may experience mild to severe constipation -- infrequent or difficult to pass stool. Constipation often causes pain, bloating, gas and general discomfort. According to MayoClinic.com, you may also experience other digestive problems, such as nausea.
Emotional Risks
Carbohydrates play an important role in mood balance. They help your body produce "feel good" hormones, such as serotonin and dopamine. While experiencing ketosis, you may experience depressive moods, mood swings and irritability. You may also feel deprived of carbohydrate-containing foods and have difficulty dining with friends or family members who adhere to healthier diets.
Weight Gain and Physical Weakness
Though you may lose weight in the initial phase of low-carb diets, once you consume even one carbohydrate-rich food, your body snaps out of ketosis. Initial weight loss caused by low-carb diets, according to MayoClinic.com, may be caused by a diuretic, or fluid-flushing, effect and/or reduced calorie intake. You may also experience physical weakness and fatigue, and find it difficult to partake in usual activities, such as exercise.
