The bottom line? If you’re thinking about trying the ketogenic diet, run it by your doctor first — regardless of any preexisting health conditions. And consult a registered dietitian nutritionist (find one at EatRight.org) to find a nutrition professional who can work with you to create a meal plan you can stick to. People with kidney disease or a history of disordered eating should avoid the diet, and people with type 1 diabetes may want to avoid it, as well. If you have risk factors for heart disease, you’ll want to speak with your doctor before considering the diet.
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).
The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if little carbohydrate remains in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures. Around half of children and young people with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists even after discontinuing the diet. Some evidence indicates that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective. Potential side effects may include constipation, high cholesterol, growth slowing, acidosis, and kidney stones.
It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients. It concluded that a third achieved an excellent reduction in seizure frequency and half the patients achieved a good reduction.
the abnormal accumulation of ketones in the body as a result of excessive breakdown of fats caused by a deficiency or inadequate use of carbohydrates. Fatty acids are metabolized instead, and the end products, ketones, begin to accumulate. This condition is seen in starvation, occasionally in pregnancy if the intake of protein and carbohydrates is inadequate, and most frequently in diabetes mellitus. It is characterized by ketonuria, loss of potassium in the urine, and a fruity odor of acetone on the breath. Untreated, ketosis may progress to ketoacidosis, coma, and death. See also diabetes mellitus, ketoacidosis, starvation. ketotic, adj.
No-sugar diet plan: What you need to know Eliminating sugar from the diet can help prevent weight gain, diabetes, heart disease, and other problems. Whether cutting sugar out of the diet completely or simply cutting back, we have eight important tips for following a no-sugar diet, and some advice about fruits and other natural foods that contain sugar.

Checking your ketone level is one way to know if you’re in ketosis. This metabolic state usually kicks in after three or four days of restricting your carbohydrate intake or going through periods of intermittent fasting. You don’t have to visit a doctor to measure your level. Pick up a ketone urine test from a nearby drug store, or use a blood sugar meter that’s capable of measuring ketones.
It seems like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto.
Normal dietary fat contains mostly long-chain triglycerides (LCTs). Medium-chain triglycerides (MCTs) are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate, leading to more food choices and larger portion sizes. The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. Consuming that quantity of MCT oil caused abdominal cramps, diarrhea, and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant. The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.
The addition of MCT powder to ketones serves the purpose of maintaining endogenous production of ketone bodies by stimulating fatty acid oxidation in the liver, which then causes the production of even more ketone bodies. In this transcript from a podcast with Dr. Dom D’Agostino it is mentioned that MCT’s cross the blood-brain barrier straight to the brain. So not only are the ketones being used by the brain as an alternative fuel but so are MCT’s.
A: The most common ways to track your carbs is through MyFitnessPal and their mobile app. You cannot track net carbs on the app, although you can track your total carb intake and your total fiber intake. To get your net carbs, just subtract your total fiber intake from your total carb intake. I have written an article on How to Track Carbs on MyFitnessPal.
The Gatorade Sports Science Institute (GSSI) is widely considered one of the world’s top go-to resources for cutting-edge exercise and nutrition science advice – which is probably why Gatorade vending machines dot the campus here, and the majority of the kids seem to be walking around campus with a never-ending big gulp-sized cup full of sports drink.

My question is: what if I want to be in ketosis for all the reasons mentioned in the Life Extension article and because I don't feel a strong urge to eat in between meals when I go lower carb and if I up carb intake I get hungrier more frequently and get urges . . . BUT on the flip side, I don't seem to digest fat all that well(dairy in particular is a no-no) and constipation is an issue and starchy carbs seem to help with that. It's a bit of a catch-22.
