To produce energy, the body typically uses carbohydrates. But after a few days on the keto diet, with its restrictive carb intake, your body cannot produce enough energy and looks for another source — breaking down stored fat to generate energy in a process called ketosis. It takes about a week for the body to start that shift from using carbohydrates or glucose, to using ketone bodies. The keto diet can help people lose weight. Some studies show those on the keto diet lose an average of five percent of their body weight, however the mechanisms are not clearly established.

Wow – that’s a lot of dairy! I’m gluten and dairy free, but I’ll watch your recipes to see what I can use. The thing that concerns me about the dairy is that casein in cheese has a molecular structure similar to gluten, difficult for my system to break that down. I wouldn’t be surprised if others with gluten issues also have the same problem. I, too, had the impression that fat = bad… but boy, am I really enjoying salads more with real vinaigrette, homemade with healthy oils. I’ve been low carb and almost sugar free for about two years because of a gut issue. But, I want to get back to cutting out the sugar… so I’ll be eager to see what you share.
The ketone bodies are possibly anticonvulsant; in animal models, acetoacetate and acetone protect against seizures. The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during a seizure, and may confer a neuroprotective effect.[55]
The good news is that snacks are totally allowed (and I're not just talking about carrot sticks.) There are plenty of packaged options out there designed for keto fans. FATBAR is one of them. These snack bars have 200 calories, 16 grams of fat, and four grams of net carbs. They're also plant-based and are made with almond or cashew butter, cocoa butter, coconut, pea protein, sunflower seeds, and chia seeds.
Some athletes swear by the ketogenic diet, not just for weight loss but for improved performance in their sport, as well. But Edward Weiss, PhD, associate professor of nutrition and dietetics at Saint Louis University, doesn’t buy it. “I hear cyclists say all the time that they’re faster and better now that they’re on keto, and my first question is, 'Well, how much weight did you lose?'” he says.
I’ve only one question. I work in shifts and at 4.30 in the morning I can not eat my breakfast (lazy – I manage to get out of bed and into my car in 30 minutes ;-). Not even if I make it the day before…I just can’t swallow the stuff. But I have to eat something because I’m in my car for more than a hour. Can I have a liquid breakfast at those times?
In the 1960s, it was discovered that medium-chain triglycerides (MCTs) produce more ketone bodies per unit of energy than normal dietary fats (which are mostly long-chain triglycerides).[15] MCTs are more efficiently absorbed and are rapidly transported to the liver via the hepatic portal system rather than the lymphatic system.[16] The severe carbohydrate restrictions of the classic ketogenic diet made it difficult for parents to produce palatable meals that their children would tolerate. In 1971, Peter Huttenlocher devised a ketogenic diet where about 60% of the calories came from the MCT oil, and this allowed more protein and up to three times as much carbohydrate as the classic ketogenic diet. The oil was mixed with at least twice its volume of skimmed milk, chilled, and sipped during the meal or incorporated into food. He tested it on twelve children and adolescents with intractable seizures. Most children improved in both seizure control and alertness, results that were similar to the classic ketogenic diet. Gastrointestinal upset was a problem, which led one patient to abandon the diet, but meals were easier to prepare and better accepted by the children.[15] The MCT diet replaced the classic ketogenic diet in many hospitals, though some devised diets that were a combination of the two.[10]
Other kinesiologists think the keto diet could have dangerous effects on athletic performance, and it's tough to know what potential side effects a long-term high-fat diet might have for a healthy person, since we don't have any solid study results yet. Low-carb diets like keto can make it easy to neglect key nutrients like magnesium, calcium, and potassium found in fresh, high-carb foods like beans, bananas, and oats.

A survey in 2005 of 88 paediatric neurologists in the US found that 36% regularly prescribed the diet after three or more drugs had failed; 24% occasionally prescribed the diet as a last resort; 24% had only prescribed the diet in a few rare cases; and 16% had never prescribed the diet. There are several possible explanations for this gap between evidence and clinical practice.[33] One major factor may be the lack of adequately trained dietitians, who are needed to administer a ketogenic diet programme.[30]


This means that if you have risk factors for heart disease — such as elevated cholesterol levels, high blood pressure (hypertension), or a strong family history of the disease — you should use caution when following this diet. The diet's heavy reliance on fat, especially saturated fat, can elevate cholesterol levels, further increasing your chances of developing heart disease in the future. (7)
Miss Mellissa…. I was doing *so well* with keto eating last summer and dropped some weight, but all the old (bad, bad) habits started sneaking in and I’m in one heck of a pickle. Just wanted to say “thanks” for this jump-start… Hopefully this will help me remember what I’m SUPPOSED to be doing. Got a long slog ahead of me, but I have hope I can make it. Your site is so, so helpful, and I really appreciate all you do. Thank you.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
