Is drinking coffee with butter and oil the key to weight loss?


Is Bulletproof coffee – coffee with butter and MCT oil – the key to weight loss? Hardly:

‘Based on scientific evidence, butter is not dangerous, but neither is it particularly nutritious,’ says an expert in public health dietary guidelines. ‘So Bulletproof coffee isn’t unsafe, but I’d still urge caution.

‘What people need to realise is that if you start adding extra fat to your diet, you had better make sure that everything else you consume is very, very low in carbohydrates.

‘If you think you can have a Bulletproof coffee and then devour a muffin without any consequences, forget it, you will start to gain weight.

MailOnline: Is drinking coffee laced with butter and oil the key to easy weight loss? Company boss Angela swears it is (but find out what the health experts say)

A high-fat coffee instead of breakfast may be fast and delicious and full of energy. But it’s not the best way to lose weight.

Let’s say you just have a cup of black coffee for breakfast (intermittent fasting) or a small amount of milk in it. You may still end up feeling great (many people, including me, do) and you could still end up in ketosis (if you’re on a low-carb or keto diet) and you’ll certainly lose more weight. Plus, you don’t have to buy any expensive branded coffee or MCT oil products.

    Those with a PhD have the right to the "Dr" moniker. It is medical practitioners who have usurped the title. Unfortunately in English we use the same word for both, but in some other languages they are two completely different words. In Japanese, for instance, the title for a PhD holder is "Hakase" and you would never use this to refer to someone who is just a medical practitioner.

    Referring to somebody simply as "Dr" on a health blog about a medical matter is not the same as what you have a right to do under some academic or societal convention. The distinction should be made explicit because of the very ambiguity in English that you acknowledge. Dropping the "Dr" and referring to her as Zoe Harcombe (PhD) is still accurate as well a being more transparent and less open to misinterpretation.

    Bulletproof coffee and fat bombs were created to help people who are in ketosis get enough fat, curb hunger and maintain the proper ratios of fat, protein and carbs. If you are consuming these things and then going on to eat a traditional diet, yes, you are going to gain weight. I know that Libby and Ditch The Carbs emphasizes this in her fat bomb recipes that this is NOT meant for people who eat a traditional diet.

    I find it disheartening that a website that promotes a low carb diet would publish such a one sided article. The whole point of the keto diet is to consume sufficent amounts of healthy fats so you feel satisfied and alert! I'm not sure what to think of this Diet Dr now.

    I agree that it's rather confusing.
    I think that Zoe Harcombe is refering to the trend to drink bullet proof coffee regardless of the diet.
    There is nothing wrong with bpc as long as weight loss is going on or if people are slim in the first place.
    For others, it may be worth trying to skip the morning cup of bpc to allow the body to continue burning its own fat, without disturbing the overnight fasting state.
    This is just my personal interpretation.

    I don't believe in this any longer. We are not thermodynamic.

    i thought the whole point of bp coffee was to get enough fat in your diet to keep you in keto.. satiety and energy are additional benefits ..

    maintaining 70pc in relation to carbs is no problem - because i have virtually zero carbs, but often have too much protein

    I believe it works as a meal replace on a keto diet, too. I have mine sometimes for late lunch and then only eat dinner. So I’m in a fasted state until then

    Tried one this morning,don’t mind the taste, will see how it goes having one a day, find the diet confusing but I am very new with it

    I love the bulletproof coffee. It kills my hunger. Then I eat my salad with protein, or eggs and butter. I found that if I only did I tbsp of butter and a tablespoon of coconut oil, I would not be hungry all day, but would have major bad cravings at night. If I put 2 tbsps of butter and a tbsp of coconut oil in my coffee, I have no cravings at night - which was my major problem before learning about the keto diet from Diet Doctor. I am so grateful, thank you for creating this website resource!

    Definitely worked for me!

    Well said. I feel the article looks either cropped or cherry picked.

    A simple black coffee may, indeed, keep you in a fasted state. From my own experience, however, a bullet proof coffee, drunk as late as possible, keeps me going without any hunger and with no compromise to my energy or concentration levels. I doubt very much if this article will have the slightest influence on those who have already experienced the benefits of a bullet proof coffee. It's also rather insulting to the intelligence - if people have used bullet proof coffee as part of their regime, it is hardly likely that they would follow it with a 'muffin'. Apart from anything else, they wouldn't need to. It's a shame if anyone is put off by this article but hopefully people will look beyond it. The fact that it had a link to the Daily Mail within it was enough to demonstrate to me that it was a load of cr*p.

    Well I have a Bulletproof coffee for breakfast and lunch, then a normal dinner. Within 2 weeks I had a lower resting heart rate, lower blood pressure, more energy and resilience. I eat some carbs at with dinner, so that I sleep well. I have lost weight, my skin in clearer, brain fog is lifting and I feel sharper. Don't let people say that the diet does not work, as I have found it works well for me. Better than Dukan diet and others I have tried. I also like to add organic cacao powder to my coffee for a rich taste. I am happy on the Bulletproof diet.

    I just started this morning. Usually I am famished by 11 a.m. today however I am not. I've gained 6 lb within a week. That is because of a Deli that I visited did not tell me that use honey on top of there brussel sprouts. I am now doing high protein and raw green vegetables. Along with my Bulletproof Coffee and I feel wonderful this morning. I am going to drop the 6 lb quickly. No other carbohydrates are allowed. I called the manager of the deli who told me he would cook my broccoli with nothing on it! Perfect. I'm going to continue to do my Bulletproof Coffee every morning , and I'm also going to blog about it day one Tama countdown to My 6 lb weight loss. I Love Bulletproof Coffee and I think this article was ridiculous. Anything that works for weight loss they want to tear down. Well kiss my grits.

    I agree with Jessica, the point of the butter is to help manage your macros. Anyone who is in a Keto diet will understand how hard it is to hit your macros without the butter and stay in an appropriate protein range.
    The rest of the benefits are not likely from the butter - the coffee gives energy and the Keto diet /MCT oil
    for the brain fog lifting.

    Thanks for article! I faced a similar situation. I also had some minor problems, and for a while I was looking for a way out to solve them. I turned to specialists. I think this is the best solution. When there is a problem, I try not to jump to conclusions, but to listen to the opinions of other people. It seems to me that because of the caffeine, I started having liver problems. Therefore, I went to the doctor for recommend black tie cbd. Thanks for your post! I will pay attention to my health, it is really very important now !!

    Well, go and read about Tom Watson in Britain, was the deputy leader of the Labour Party. Forget the politics as he's left politics, just read what he did. He lost stones, and bullet coffees featured in his diet. Took England by storm some years ago. Now Tom is trying to get kids from becoming obese.
