The "bulletproof coffee" diet has caused a whirlwind at home and abroad! Adding oil to coffee is said to make people lose weight, boost their spirits and even lower their blood sugar, causing people to follow suit and try. Nantou Hospital dietitian said that the concept of bulletproof coffee with low sugar and high fat is similar to a ketogenic diet, which provides a sense of satiety and suppresses appetite, has the effect of weight loss, and because the proportion of sugar intake is reduced, blood sugar decreases, but it cannot treat diabetes.

Bulletproof coffee originated abroad, the general practice is to mix the freshly brewed coffee with a large amount of fat and drink it, while the oil is made with coconut oil and cream. Huang Shumin, a dietitian at Nantou Hospital, said that coconut oil has an 8-10 carbon chain and belongs to medium-chain fatty acids (MCT oil), which can quickly pass through the inner membrane of the mitochondria and be absorbed directly by the body. Huang Shumin warned that high-risk groups such as diabetes, pregnant women or improper use are prone to the risk of ketoacidosis, which should be carried out after consultation with doctors and dietitians.

Huang Shumin pointed out that a cup of bulletproof coffee, which contains almost no carbohydrates and protein, will cause the body to produce ketones because there is no glucose as fuel, a diet high in fat and low in sugar or due to diabetes (diabetes mellitus DM) leads to severe insulin deficiency, glucose in the blood can not be used normally, so by accelerating the decomposition of fat to supply cell energy instead of glucose, but fat decomposition will produce large amounts of free fatty acids, fatty acids will enter the tissue cells and liver. It provides heat in tissues and cells; if it enters the liver, it will alienate and produce a large number of ketone bodies. Use a lot of burning fat to achieve the goal of weight loss, let the ketone body replace glucose, this is the charm of bulletproof coffee.

Huang Shumin says that low-sugar, high-fat foods are clinically called "ketogenic diets," while ketogenic diets are mostly used in patients with epilepsy and are suitable for individualized treatment. The hospital recommends that the public must be carried out under the supervision of doctors and dietitians, and that ketogenic diets are not easy to implement, difficult to sustain, and usually not used for a long time. It is recommended that if ordinary people want to taste bulletproof coffee, please drink a small amount, and should go with a balanced diet and proper exercise, and consult a doctor and dietitian if necessary, which is the only way to lose weight healthily.
