As the time sequence approaches summer every year, trendy ways to lose weight are springing up like bamboo shoots after a spring rain. Recently, the bulletproof coffee diet has been rammed. I have heard that many Hollywood stars have tried it.

Bulletproof coffee (Bulletproof Coffee) was created by Dave Yaspree (Dave Asprey), an American Silicon Valley engineer. It is said that when Dave was on a trip to Xizang one year, a local gave him a bowl of "yak butter tea." after drinking it, he immediately felt warmer and full of energy all day, as if he had a feeling of "bulletproof coffee." so he studied it for a long time after returning home and developed the method of "bulletproof coffee." He found that this kind of coffee is not only delicious, but also has the effect of losing weight, allowing him to lose weight smoothly, who suffered from obesity when he was young.

Inspired by the principle of buttered tea, similar to a ketogenic diet.

For bulletproof coffee, add one to two tablespoons of salt-free forage feed cream to organic black coffee, and add one to two teaspoons of medium-chain triglycerides (Medium-Chain Triglycerides,MCTs, a digestible fat) or organic coconut oil to a blender to beat coffee like a latte. The simple version is a cup of black coffee (240 grams), add a spoonful of cream and a spoonful of coconut oil, stir and drink.

With regard to the weight loss effect of bulletproof coffee, Bai Xiaoliang, PhD in nutrition education at Columbia University and author of "Don't let the wrong concept of Nutrition harm you," pointed out that it can be seen in two ways: first, caffeine can indeed accelerate the body's metabolism. But if you want to talk about its weight loss effect, it depends on your physical fitness. "people like me who drink two cups of black coffee a day, drinking more coffee will not have a weight loss effect." But for people who are prone to heart palpitations and other problems after drinking coffee, they may be able to see obvious results. "

Moreover, the coconut oil used in bulletproof coffee belongs to vegetable saturated fatty acids and will feel full after drinking, but Bai Xiaoliang said that too much oil can still lead to the hoarding of blood fat in the blood, which is bad for health.

Second, the bulletproof coffee diet does not consume carbohydrates, which is similar to the "ketogenic diet" that has been highly discussed recently. "A ketogenic diet does have an effect in a short period of time, but I wouldn't call it a 'useful way' because it's dangerous to lose weight!"

Bai Xiaoliang said that the effect of ketogenic diet can actually be seen in people with diabetes, who usually lose weight because there is something wrong with blood sugar control and the body loses muscle.

If you lose weight in this way, once you return to a normal diet, you will soon start the rebound mechanism, and what will come back to the body will be tough fat.

Bai Xiaoliang, who once taught at Montclair State University in New Jersey and is currently an associate professor at New York City Community College in the United States, admitted that she had lived in the United States for many years and had not actually heard of the "bulletproof Coffee weight loss Act." she believes that the effectiveness of a case can only be a case, not as a theory, and she does not recommend this way to lose weight.

It's not the weight but the body fat that should be lost.

Pai Hsiao-Liang believes that in fact, there is only one way to lose weight, that is, "the calories consumed are greater than the calories consumed." if you want to lose 2.2 kilograms of body fat within a week, you must lose 3500 calories, or about 500 calories a day. "it should be noted that 'body fat' is not weight, weight loss will only reduce the body's muscles, whether it is weight gain or weight loss, should not increase body fat." She stressed.

"despite the fact that we Asians seem to be very thin and small, in fact, our body fat is much higher than that of tall whites in foreign countries, just because Asians have not formed the habit of exercise." Therefore, if you want to increase the amount of calories consumed, in addition to increasing the body's basic metabolic rate, the best way is to exercise. Bai Xiaoliang, for example, takes as few escalators as possible when taking the MRT, and take the stairs instead. This is the best alternative for office workers when they say they don't have time to exercise.

What is a ketogenic diet?

The principle of a ketogenic diet is no stranger to people in the weight loss world. It was the "meat diet" put forward by Dr. Robert C. Arkins. In recent years, there is a popular "sugar-cut diet" in Japan, which forces the body to burn fat rather than carbohydrates through a diet high in fat, moderate protein and low in carbohydrates.

Because the ketogenic diet consumes only a small amount of low carbohydrates, the liver converts fat into fatty acids and ketone bodies, and the ketone bodies are transported to the brain to replace glucose as an energy source. When the content of ketone bodies in the blood reaches a certain level, it is ketosis, which can alleviate the frequent seizures of epilepsy. Therefore, in the past, ketogenic diet was mainly used to treat epilepsy in children, but in recent years, many people have found that it also has the effect of losing weight. So they flocked to it.
