Here’s the Skinny on the Bulletproof Diet

Fat that can make you thin? Hollywood seems to be buying it.

“I start almost every day with something called Bulletproof Coffee,” Divergent star Shailene Woodley has said of the high-fat breakfast concoction that combines special low-mold coffee beans, grass-fed, unsalted butter and so-called Brain Octane Oil, which is a coconut oil extract. (Brandon Routh and Ed Sheeran are reportedly also fans.)

It sounds more like an indulgent dessert — but according to Dave Asprey, author of the new book The Bulletproof Diet, the high-fat content in his Bulletproof Coffee recipe is his secret ingredient to weight loss and increased energy.

“You will have no interest in food for four to six hours,” Asprey tells PEOPLE of drinking only this cup of Joe to start the day. “It makes your brain work better because you are not distracted every time you see a cookie lying around. You don’t even think about food.”

When it comes to lunch and dinner, the rest of Asprey’s diet plan is just as fat-focused. That means filling up on lots of fats — like ones found in butter and guacamole — plus veggies and grass-fed proteins (which he says have more nutrients and fewer toxins than grain-fed meats).

“When you teach your body that it’s going to use fat for fuel, it helps you go into fat-burning mode, called ketosis,” says Asprey, who claims that his comes without the suffering many feel on other low-carb diets that can take days to get the body into fat-burning mode. “By using the extract of coconut oil in the coffee, it’s kind of cheating. It puts your body into the state where it get energy from fat right away.”

While he recommends taking gluten off the menu, Asprey says, “You can have carbs [think rice or sweet potatoes], but you have them at the right time, so that they help your sleep, instead of giving you food cravings all day long.”

Sounds like something we’ll have to try after the holiday season.

Probably won’t make you think about food since you typically don’t want to eat much after you have massive diarrhea. That’s basically a buttery laxative. Real smart.

Says the author who has diabetes…..

I know a registered dietician who works for a hospital and she says everything in moderation and use portion control. She would never support an unhealthy meal plan like the one in this diet! That should tell you something.

Coffee with coconut oil sounds horrible. I would never be able to drink that. I remember when coconut oil first became popular and I tried to use it but I just never liked the taste. I guess this will be the latest Hollywood fad diet.

I work in healthcare, the healthiest people I see at any age, are those with a positive attitude who eat a variety of mostly natural foods in moderation. In other words, anything “diet” that has a lot of Hollywood people following it, is probably not the best. The Mediterranean diet is the one our hospital follows. Mostly natural foods, less processed.

This is a joke right?…

My nutritionist recommended bulletproof coffee to me almost 2 years ago. I was not a coffee drinker and I thought it sounded strange, but I gave it a try. Drinking this coffee (with coconut oil, grass-fed butter, and stevia) as my breakfast helped me to lose 35 lbs. I also began eating only grass-fed or free-range meats, with fewer carbs only in the evenings. My blood work is great and I have pretty much kept the weight off. If I don’t have the coffee, I eat eggs from our own free-range chickens and also 4 pieces of Beeler’s uncured bacon for breakfast every day. I am not hungry for 4-5 hours, when before I would be hungry within an hour. It has worked for me and the proof is in my bloodwork and the scale!!

I went to school for nutrition. One of the classes I had to take was about current nutrition topics. I remember one time the professor and 60+ students were laughing at these celebrities and how dumb their fad diets were. Most of these celebrities are morons and they’re promoting dangerous diets.

The amazing thing about all diet fads throughout human history is that 100% of them, without fail, end with people fatter and crying in the corner thinking they could outsmart basic science with some foreign “secret”.

This is the paleo diet with a coffee in the morning. Healthy fats, proteins and vegetables. Low carb, no gluten grains. Nothing new. When applied faithfully it will heal autoimmune disease. It did for me. The side effects are normal weight, excellent blood work, normal blood pressure, etc. Not sure where all these people who know a nutritionist are coming from. And just because the article says “celebrities are doing it” doesn’t mean those idiots have a monopoly on good eating. Even a blind squirrel …

a cool way to improve on

You may find yourself limited to long shots until you can get those passing movements working. Now you’ve reached the point where you have to complete a Kanto sidequest unique to Pokemon Heart Gold, Soul Silver, and the original Gold, Silver, and Crystal. On larger maps the Shadow is in fact the Core’s best option for mounting an effective early-game offensive.
