The "bulletproof coffee", which is popular on the Internet, is a magic medicine to lose weight or a hoax.

"when you get up in the morning, do you feel like you can't wake up? Do you feel backache when you squeeze off the subway? When you finally get to the office, do you feel unable to concentrate? " After saying these symptoms, the next sentence of the advertisement in our country is: is the kidney overdrawn? But Asprey, an American entrepreneur, said: you have to drink bulletproof coffee (Bulletproof Coffee, BPC).

Replace breakfast with BPC, you will have mental and physical strength that lasts all day, and you will be able to lose weight. You see, I lost 100 pounds. (summarized from the original words of Asprey)

The discussion about the use of eggs is later on. Anyway, bulletproof coffee has gained a lot of fans in recent years, and many Silicon Valley tech people love this cool techs breakfast. No wonder investors are also generous. BPC, founded in 2011, has just raised $9 million, according to Venturebeat. In an interview with Venturebeat, the founder said his ideal was to "build a billion-dollar brand, not an e-commerce that touches hundreds of thousands of people".

The first experience of Western-style buttered Tea

Asprey tasted the local buttered tea when he traveled to Xizang in 2004. After drinking it, he found that he had no altitude sickness. Later, when he spent 300000 dollars trying various foods like Shennong tasting herbs to study the body's response to various foods, the memory of buttered tea popped up, and he replaced all the recipes for buttered tea with Western food, which is bulletproof coffee. The formula of "Western buttered tea" is simple: high-grade non-toxic coffee bean extract coffee, add a piece of grass-fed butter and a small cup of medium-chain triglycerides (called "brain octane oil").

According to Asprey, using this 400-to 500-calorie cup of Western-style buttered tea for breakfast can suppress hunger, lose weight ("ketogenic diet") and improve cognitive ability. Do you think of the "endless" smart medicine? Or amphetamine on an electric campaign hand?

An editor of FastCompany had a two-week experience with BPC and wrote a detailed diary. Overall, his feelings are mixed. He believes that BPC does provide "a lot of energy" and has reservations about the features advocated by Asprey's ambitions. Here are some highlights of his experience report:

A few days ago, I obviously felt that I was very energetic, but I was hungry after 10:00.

On the fourth day, hunger after 10:00 caused a slight stomachache.

On the fifth day, I ate a piece of toast before drinking BPC. "I've never felt better".

On the sixth day, due to the lack of time for BPC to do relatively light, as a result soon hungry, so eat a doughnut, feel "very good, everything is very good".

On the 8th day, I only drank BPC for breakfast. I was hungry again later, and I had a severe stomachache.

On the 9th day, I drank a spoonful of protein powder granule before drinking BPC, which felt "very wonderful".

On the 14th day, the refreshing effect is still obvious, but I miss solid food very much.

Judging from this report, BPC does have a significant pick-me-up effect, although it may have little to do with brain octane oil. Second, the calorie equivalent of coffee in a McDonald's hamburger doesn't keep you full all morning, so using BPC for breakfast doesn't make sense. It is also worth noting that the author shows great satisfaction after adding meals in the morning, so it should not be easy to insist on BPC.

Experts say: bullshit

Asprey said residual mycotoxins in coffee can lead to bitterness and "excessive tiredness". Expert: bullshit. Authority Nutrition editor-in-chief pointed out that the bitterness in coffee comes from tannins, not mycotoxins. There is also no basis for toxins to reduce the effectiveness of coffee, as coffee producers have solved the mold problem with wet treatment for years, and currently the residues of mycotoxins and other toxins in standard coffee are well below the maximum safe dose.

Taking a closer look at the recipe, there are many more points of doubt, and another article edited by Authority Nutrition pointed out three main problems with BPC:

BPC lacks the core nutrients in nutritious breakfast. Although high-fat BPC can provide energy for the brain and provide a sense of satiety (which is different from the above report), medium-chain triglycerides are unnutritious calories.

Saturated fatty acids are good, but not even if you overmeasure them.

There are cases in which BPC causes a sharp rise in cholesterol.

Whether it's Shenbao or BPC, "divine effects" always have amazing transmission power, because it is much easier to hope that unknown "science" will acquire "superpowers" than to change yourself based on solid knowledge. In my opinion, in order to achieve the magic effect advocated by Asprey, nothing but eat, drink, exercise and sleep regularly.
