Ketosis occurs when the body does not have enough carbohydrates to completely metabolize fat for fuel. Instead, it uses protein for fuel. Although the American Heart Association does not recommend this method, some people choose a keto diet for weight loss. Another use for the keto diet is to control epilepsy. Foods for a keto diet must be low in carbohydrates so that the body remains in ketogenesis.
Butter
Butter is a food for a keto diet because it contains no carbohydrates. Instead, it is pure fat. Other pure fats that have no carbohydrates and are foods for a keto diet include shortening, lard and oils. Plant oils, such as vegetable, flaxseed or olive, may be healthier choices than solid fats like butter and lard because they are lower in saturated fats. Heavy cream also has minimal carbohydrates and is a high fat food for a keto diet. You can eat unlimited quantities of these fats because they do not contribute enough carbohydrates to let your body use fat as fuel. However, if you are trying to lose weight you should remember that fats are high in calories and regardless of the source, too many calories will prevent weight loss.
Steak
A keto diet emphasizes high-protein foods, such as meat. Cuts of steak such as filet mignon, T-bone, ribeye and sirloin are all high in protein and fat, and almost free from carbohydrates. This makes steak a good food for a keto diet. The Harvard School of Public Health recommends choosing lean cuts of red meat to reduce the amount of total and saturated fat that you consume. Other fresh animal proteins, such as ground beef, poultry, eggs and fish, are also foods for a keto diet. When choosing a meat for a keto diet, be careful of packaged or processed meats such as hot dogs or sausages. These may have ingredients such as sugars or fillers that can contribute carbohydrates and undermine your keto diet.
Broccoli
Broccoli is a food for a keto diet that you can eat in moderation because according to Keto.org, broccoli provides only a few carbohydrates. Other green leafy and cruciferous vegetables like chard, spinach and lettuce are also low in carbohydrates but healthy. They are high in dietary fiber, vitamins and minerals. According to the Harvard School of Public Health, the greatest benefit from eating plenty of vegetables may be the effect on heart health, including lowering the risk of stroke or developing coronary artery disease. Other potential benefits of eating adequate vegetables include lower blood pressure, healthier eyes and a possible lower risk of cancer.
