Whether you’re whipping them into a recipe or snacking on a handful of them raw, blackberries can make a great addition to your keto meal plan. A ½-cup serving doesn’t contain much fat (less than ½ g) but is also low in net carbs, with just 3.1 g. The same serving size offers 3.8 g of fiber (15.2 percent DV) and 3.5 g of sugar. Blackberries also provide potassium, with 117 mg (2.5 percent DV) per ½-cup serving. It has 15.1 mg of vitamin C (25.2 percent DV) and 14.3 mg of vitamin K (17.9 percent DV). This fruit is also a great snack for weight loss, containing about 31 cal per ½ cup.

The reason purity matters is that C17 is a byproduct of most MCT oil production processes, and it, along with C6, is a major cause of throat burning and gut irritation. Most MCT’s on the market are manufactured via chemical and solvent based refining, which involves using chemicals like hexane and different enzymes and combustion chemicals, such as sodium methoxide. But ideally, you should get an MCT oil that is made using triple steam distillation in a non-oxygen atmosphere to avoid lipid oxidation and create a purer end-product.

Similar to the BHB salts and MCT’s from the KETO//OS I discuss above, powdered forms of ketones are excellent if you don’t want to completely eliminate carbohydrates or protein (which can be gluconeogenic when eaten in excess) or eat copious amounts of fats, but want to simultaneously maintain high levels of blood ketones. It may also be used to ease the transition into a ketogenic state, because it can help alleviate the fatigue and lethargy some  people experience while making the transition from a glucose metabolism (carb burning mode) to ketone metabolism (fat burning mode).
2) I'm currently using Ketocana and in that section you state "Similar to the BHB salts and MCT’s from the KETO//OS I discuss above, powdered forms of ketones are excellent if you don’t want to completely eliminate carbohydrates or fat or eat copious amounts of fats, but want to simultaneously maintain high levels of blood ketones." – How would eating copious amounts of fat be a negative? Wouldn't that help contribute to a ketogenic state?
Because some fruits have more carbs than others, knowing which to avoid is key for accelerating weight loss and reaping other possible benefits of keto. Just know that large, long-term, randomized controlled trials on the keto diet are limited, so it’s unclear whether keto is safe and effective to follow for the long haul, according to Harvard Medical School.
I’m not sure if I really understand the idea of exogenous Ketones putting ones body into a state of KETOSIS, in that their own fat cells will be burned for fuel. Won’t the body just use the exogenous ketones and energy and continue to use glucose sources as well? How does taking ketones, make the body burn it’s own fat stores? I always thought that one would have to be in a state of energy deprivation for the body to actually begin to use the TG in the fat cells to generate ATP. Please let me know what I’m missing…
I knew keto was on the The Today Show when relatives began dropping the term in the same charming way your grandmother might refer to “the Instagram.” They knew it was low carb and that it worked, because that’s what the show told them. But they couldn’t explain the state of “ketosis” or why their Yummy Yummy Dark Chocolate Sea Salt Breakfast Replacement Keto Bar was a better choice for weight loss than, like, cutting back on alcohol.
On the keto diet, your body begins to shed fat, water and glycogen, and as this happens you lose key electrolytes, such as sodium, potassium and magnesium. When you're running low on these electrolytes, you might experience headaches or extreme fatigue. These losses are most pronounced during the first few weeks after you enter ketosis, so if you're going to start the keto diet it's best to plan ahead to make sure you get healthy amounts of these electrolytes — and other vitamins and minerals — either through supplements or a thoughtfully-designed meal plan.

But sadly, whether due to government subsidy of high carb foods like corn and grain, funding from big companies like Gatorade and Powerbar, our sugar-addicted Western palates, or the constant (unfounded) fear mongering about saturated fats and heart disease, the type of research that shows these fat-burning and performance benefits of carbohydrate restriction simply get shoved under the rug.

I asked James Fell if he had some practical advice on sustainable dieting. “When it comes to weight loss,” he said, “the only thing that matters is caloric deficit. However, quality of diet affects quantity. A higher quality diet is more likely to be one that allows you to eat a lower quantity of calories and still be satisfied. That being said, there are many different ways to find a high-quality diet.”
The diet is extremely regimented and very difficult to stick to, as just one baked potato and one slice of bread could hold an entire day’s worth of carbohydrates. While this is a deterrent for many, Christy Brissette, RD, a private-practice dietitian in Chicago, notes that many of her patients like the diet because of its strictness. “Some of my clients feel that the keto diet works for them because it doesn't involve any calorie counting and the rules are simple to understand,” she says. “They feel they have strict parameters that can take the guesswork out of dieting.”
Hi Cyn, The numbers are general guidelines but will vary depending on many factors, such as activity level, insulin resistance, weight and more. There is no single magic number, just conventional recommendations that are a good starting point. I will have a macro calculator coming soon that will help determine what is best for each person, but even then it’s an approximation. The only way to know for sure is to test. If keto is your goal, it’s usually best to start lower and then see if you can stay in ketosis when increasing.
The original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories[Note 1] to maintain the correct weight for age and height. The classic therapeutic ketogenic diet was developed for treatment of paediatric epilepsy in the 1920s and was widely used into the next decade, but its popularity waned with the introduction of effective anticonvulsant medications. This classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains, and sugar, while increasing the consumption of foods high in fat such as nuts, cream, and butter.[1] Most dietary fat is made of molecules called long-chain triglycerides (LCTs). However, medium-chain triglycerides (MCTs)—made from fatty acids with shorter carbon chains than LCTs—are more ketogenic. A variant of the classic diet known as the MCT ketogenic diet uses a form of coconut oil, which is rich in MCTs, to provide around half the calories. As less overall fat is needed in this variant of the diet, a greater proportion of carbohydrate and protein can be consumed, allowing a greater variety of food choices.[4][5]
You need to do a “common man’s” version of a good ketogenic nutrition program or discussion. Great article, and I leaned a few things. Those Ketone Salts and other supplements can get pricey. I eat a very low carb and high fat diet and meander in and out of ketosis during the week. A pure ketogenic diet is so restrictive that meals it can get very repetitive during the week. I’d like to learn more about cooking with oils and how temperature effects their qualities. I can only handle eating so much raw food, and I love to cook my greens and other vegetables in bacon fat and coconut oil. It will be next May before I can get my blood work performed (insurance reasons) so until then I’ll need to be careful and hold back on those after supper dark chocolate excursions! Thanks!!
This is the second shortest form of MCT, also rare and comprising about 8% of coconut oil. It is slower to turn into energy but less expensive than C8. XCT Oil is triple-distilled in a non-oxygen atmosphere with no solvents, and it contains C10 and C8, because these are the only two MCT oils that turn into ATP quickly without the liver. You would need 6 tablespoons of coconut oil to get one tablespoon of XCT oil.

I just discovered your site and have been thoroughly enjoying many of the articles and appreciate that you get so in depth in your explanations. I’m in my late 40’s and, while not an extreme endurance athlete, I am moderately active with 18-20 mile rides 3x a week as well as some boxing and body weight resistance (push up, pull up, etc) mixed in. I’ve generally been paleo and stick to quality macros for the most part (grass fed meats/dairy, organic veg and oils) and zero supplements. I recently started following keto (after reading this article) about 10 days ago and things seem good thus far. I do, however, want to avoid any of the negative side effects you mention and also not lose any lean muscle. I’m currently about 174 lbs, 5’8″ and about 19% bodyfat – I’m taking in about 95g protein, 130g fat and <20g net carbs. I'm eating all quality – wild salmon, grass fed beef, pastured eggs, coconut oil, Brain Octane and Grass fed butter in coffee, sardines, etc. With a smattering of organic veg, but it seems real easy to bust through the carb barrier. *I'M ALSO TAKING KETOCANA PRE-WORKOUT* and I notice this is keeping me going throughout a ride or the gym.
And here’s the reality of the situation. Not all carbs are created equal. There’s a lot of cleverly labeled and modified maltodextrin on the market claiming to be some technical polysaccharide. Or, there’s plain old cornstarch relabeled as super-duper muscle engorging waxy maize. Most of these aren’t proven to do anything except deliver false hopes, high blood sugar, and gut issues – as opposed to having multiple clinical studies in real athletes to support what it is they’re claiming.
When you burn key tones as a funeral, whether they are from a supplement or whether they are the ones that your body makes, you do indeed become more efficient utilizing ketones. So that is one advantage. You are correct in that if you simply use these and you do not restrict carbohydrate intake then you're not going to get quite as much benefit. I am a fan of combining these with intermittent fasting, MCT oil, and a high-fat diet.
No offense brother, but this whole article is a big selling advertisement. The health benefits of a “low – carb, high – fat” diet are well known and proven. I directly blame nutritionists, like yourself, for the fact that ~70% of American is considered obese now, not fat, obese. And the fact that Heart Disease is the number 2 killer in America now, second only to cancer.
