Recent studies indicate that mood disorders such as depression and anxiety can be linked to a range of physical changes in the brain, such as inflammation or change in gene expression71. Early results from animal studies have shown that ketosis could improve mood disorders, although the mechanism is still unclear. Rats fed exogenous ketones for several weeks showed reduced anxiety behaviours72. Similarly, endogenous and exogenous BHB alleviated depressive behaviour in mice subjected to stress73. This was found to be linked to altered epigenetic markers (modifications to DNA that affect the degree of gene expression) and an increased amount of brain derived neurotrophic factor (BDNF) in the brain. At this time, there are no trials investigating the effects of ketosis in human patients with mood disorders. 
But people who started following the keto diet noticed weight loss for a few reasons: When you eat carbs, your body retains fluid in order to store carbs for energy (you know, in case it needs it). But when you’re not having much in the carb department, you lose this water weight, says Warren. Also, it's easy to go overboard on carbohydrates—but if you're loading up on fat, it may help curb cravings since it keeps you satisfied.

Children who discontinue the diet after achieving seizure freedom have about a 20% risk of seizures returning. The length of time until recurrence is highly variable but averages two years. This risk of recurrence compares with 10% for resective surgery (where part of the brain is removed) and 30–50% for anticonvulsant therapy. Of those that have a recurrence, just over half can regain freedom from seizures either with anticonvulsants or by returning to the ketogenic diet. Recurrence is more likely if, despite seizure freedom, an electroencephalogram (EEG) shows epileptiform spikes, which indicate epileptic activity in the brain but are below the level that will cause a seizure. Recurrence is also likely if an MRI scan shows focal abnormalities (for example, as in children with tuberous sclerosis). Such children may remain on the diet longer than average, and it has been suggested that children with tuberous sclerosis who achieve seizure freedom could remain on the ketogenic diet indefinitely.[45]

I have changed to a Ketogenic Lifestyle for over a year and half now. This is not a Diet is a lifestyle change. I choose to be healthy and weight loss is an awesome side effect. I’m over 100lb down, no more diabetes, I reversed my fatty liver disease, and I am totally off all blood pressure medication. I have more energy and now able to work out 5 days a week. My blood work had never been better including my cholesterol levels. I’ve tried every diet and nothing worked. I respect your opinion and your post on the blog, but Keto has been a lifesaver for not only me but my family as well. I wish you well in your journey and I’m glad you found a WOE that works for you. I’m living proof Keto works.
Risks to Note Kizer says there are a few groups who should not follow the standard version of keto (or any other version either): pregnant women, people with diabetes (at least not before discussing it with a physician), and those with a history of kidney stones. She notes that ketosis may result in bad breath, dizziness, constipation, and low energy levels (commonly called the “keto flu”) for the first few weeks. More concerning, drastic weight changes, from keto or otherwise, can increase your risk of mortality, says Kizer. Weight cycling, also called yo-yo dieting, may put particular strain on the heart, suggests a study published in February 2015 in Obesity Reviews.

The 2017 meta-analysis by Drs. Kevin Hall and Juen Guo provide us with very convincing data, but we must also consider the fact that the data came from studies where all the food was provided by the scientists. Although this is a great way to assess the difference between low-carb and high-carb diet, this does not simulate the real-world effectiveness of each diet. For this reason, we must investigate data from less strict studies. In other words, we need to look at what happened when subjects were told to follow a specific diet on their own.
You should be lowering your carb intake sufficiently, especially if your diet is regularly high in carbs. When you eat carbs, they’re broken down into glucose, which spikes blood sugar levels. This causes strong insulin levels to combat the spikes, resulting in fat storage and insulin resistance. With the keto diet, you should be getting about 10% of your energy from carbs, 15-25% from protein, and 70% or more from fat.
Make things yourself. While it’s extremely convenient to buy most things pre-made or pre-cooked, it always adds to the price per pound on items. Try prepping veggies ahead of time instead of buying pre-cut ones. Try making your stew meat from a chuck roast. Or, simply try to make your mayo and salad dressings at home. The simplest of things can work to cut down on your overall grocery shopping.
Absolutely Steve. I love ranch salad dressing, cheese, cream cheese, steak, shrimp, and some vegetables. I am making “fakery” to satisfy my sweet tooth. (Fakery is baking using almond or coconut flour instead of wheat and white flour, and Swerve sweetener instead of sugar (made with Erythritol which has no impact on GI and is good for your teeth) I am over half way to my goal already. Thank you for your article. I appreciate your dedication, knowledge and sharing with the world. (and your cute animal gifs)
Take coconut oil for example. The coconut oil industry loves to market the idea that relatively inexpensive and abundant coconut oil is a great source of MCTs because it’s “62% MCT oil”, but the problem is that studies show you can’t get many useful ketogenic MCT’s from just eating coconut oil or even most brands of “MCT oil”, which are often is diluted with lauric acid, a cheap, hugely abundant part of coconut oil that is typically marketed as an MCT oil.

But if no carbs are available, our bodies start burning fat as a primary fuel source and producing ketones in the liver, which the body can turn into energy. This metabolic state, called ketosis, is what happens when someone is starving. But it's also how Harper's body works every day. His system relies on fats like butter, oil, and lard as a primary energy source instead of packing them on as in-case-of-emergency poundage.


In the end, I'm pleased with my keto diet results both internally and externally. I lost 4 pounds in two weeks, gained some energy and efficiency with my training, and more often than not felt that I could see better muscle tone instead of feeling bloated or weighed down. While the ketogenic diet may not be my go-to on a regular basis, Dr. Axe's final feedback was encouraging: He says because I've now had a successful keto trial run, if I wanted to cycle through some keto weeks (or even a month, next time), I'd be able to easily, potentially reaching ketosis even more quickly. While going full-force back on the carbs could derail me or anyone else who wants to keto-cycle, Dr. Axe says the odds are in my favor. “Ninety percent of the time if someone's done it once, they will get into ketosis quicker and easier the next time,” he says.

The bulk of research suggests that the ketogenic diet is more effective than conventional diets in helping you lose weight and shed body fat. One of the reasons why the ketogenic diet provides such reliable weight loss results is because it consists primarily of highly-satiating whole foods like meat, high-fat dairy, and low-carb vegetables while removing all carb-rich, sugar-laden processed foods from the diet. By eating in this way, you will feel full while eating fewer calories and losing weight.


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]


Also, take special note of sugar alcohols like sorbitol, mannitol, xylitol, and isomalt. Sugar alcohols are derived from plant products (ie., fruits and berries), though their carbs are uniquely altered through chemical processing. While sugar alcohols provide fewer calories than table sugar, people often overeat them because they are labeled as “sugar-free” or “no sugar added” foods. This is problematic because they can still spike blood glucose levels due to their carb content. You still need to account for them in your diet plan.[2] Your best bet is to go with erythritol because it doesn’t cause blood sugar or insulin spikes.

Ben, great article! I recently did my own ketosis experiment and didn’t catch the 100-200g advise until later than I should have, I’m guessing. Great results for 1-2 months but after 3 months I quit sleeping through the night and would wake after about 4 hours of rest each night. My guess is that the extra carbs at night coupled with iodine supplements should allow me to “have my cake and eat it too?” Any other suggestions on the sleep issue? I’ve gone back to High Fat/Low Carb, have improved sleep but I do miss nutritional ketosis and want to try again once my sleep is stable. Thank YOU!!!
I did keto for quite awhile for weight loss reasons. I also had the same experience of being scared of food after being on it long enough. I realized that this way of eating was just not right for me. I mean, it got to the point where I’d sometimes just not eat. At the beginning of this summer, I decided it was best to just watch my calories to lose the rest of my weight (100 lbs gone from keto). Unfortunately, I started having very unwelcome effects of changing my diet to low cal. I started getting shaky, lightheaded, dizzy, nauseous, my vision blacked out, etc. This happened every single time I ate. Turns out that because I cut back so low on my carbs for so long and lost so much weight, my body couldn’t handle the carbs after eating. Thankfully, my doc finally just figured out what was wrong after a good couple of months of suffering. I have reactive hypoglycemia. My body overproduces insulin when I eat. My body essentially crashes.
"I'll typically have two chocolate peanut butter fat bombs. They save me. Lately, there’s been a keto cheesecake in the fridge and I’ll sneak a bite, but won’t have a whole piece. I try not to go too hard on the snacks anymore. I’m noticing that laying off the almond flours, coconut flours, and baked sweets has helped me feel better overall. If I want a crunch I’m reaching for the pork cracklings."
Your current health status. Your overall health plays a major role in how fast you will lose weight and adapt to a lower carb diet. If you have any hormonal or metabolic issues, weight loss might be slower or a bit more challenging than expected. Insulin resistance, excess visceral fat, and thyroid issues, for example, can all have a significant impact on your weight loss rate.
Nutrient-sensitive neurons reacting to glucose but also to fatty acids (FAs) concentrations are present at many sites throughout the brain and may play a key role in the neural control of energy and glucose homoeostasis. Central administration of oleate, for example, inhibits food intake and glucose production in rats. This suggests that daily variations in plasma FA concentrations could be detected by the CNS as a signal that contributes to the regulation of energy balance (Moulle et al., 2014).

Kite Hill Almond Yogurt, plain. I picked it up at Mother’s Market in SoCal, although I’m sure other nationwide health food chains would carry it. It’s really rich and I enjoy it sprinkled with some New Zealand sea salt crystals. The crunch and saltiness of the crystals really complements the richness and nuttiness of the yogurt. One net carb per serving!!
For some, ketosis can cause more negative than positive side effects. Dorena Rode, a 52-year-old author, and speaker from Occidental, California, tried the diet for a month and experienced heart palpitations and dizziness. Unlike Drew, Rode says her cholesterol increased from 192 to 250 mg/dL after she introduced more fat into her diet. (Less than 200 mg/dL is considered desirable, while anything over 240 mg/dL is considered high.)

The low glycaemic index treatment (LGIT)[48] is an attempt to achieve the stable blood glucose levels seen in children on the classic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet,[9] which occurs because the absorption of the limited carbohydrates is slowed by the high fat content.[5] Although it is also a high-fat diet (with approximately 60% calories from fat),[5] the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40–60 g per day.[3] However, the types of carbohydrates consumed are restricted to those that have a glycaemic index lower than 50. Like the modified Atkins diet, the LGIT is initiated and maintained at outpatient clinics and does not require precise weighing of food or intensive dietitian support. Both are offered at most centres that run ketogenic diet programmes, and in some centres they are often the primary dietary therapy for adolescents.[9]
I’ve been on Keto for o ver a year now and I am delighted about how I look and feel. I’m 71 years old and I have more energy now and no pain for the first time in such a long time. I lost 35 lbs in about 4 months and have kept it off with no trouble. I do follow it pretty strict but not afraid to eat a few no nos. My husband of 51 yrs passed away and I’m alone to take care of a 40 acre farm. Friends and neighbors are amazed at the work I am able to do. In fact they’re asking me about the Keto diet. I do hard labor on my farm and 2 days a week I do weight exercise. My blood sugar and trygicerides are low and soon will be off high blood pressure meds soon. Everyone says how great I look.
The ketogenic diet reduces seizure frequency by more than 50% in half of the patients who try it and by more than 90% in a third of patients.[3] Three-quarters of children who respond do so within two weeks, though experts recommend a trial of at least three months before assuming it has been ineffective.[9] Children with refractory epilepsy are more likely to benefit from the ketogenic diet than from trying another anticonvulsant drug.[1] There is some evidence that adolescents and adults may also benefit from the diet.[9]
Look into cold showers and ice baths for relief from depression along with all the other benefits it provides. If you’re willing to push your comfort zone, you’ll find that cold showers/baths provide a monumental difference. There’s some research out there that identifies the benefits of combining specific ketogenic diets and ice baths. And I used this to increase gains in the gym, reduce inflammation, feel better in general, builds patience and raises tolerance levels. It’s impressive stuff. Cold and heat thermogenesis for the win (heat would be sauna/steam room, but cold is what helps you sleep better and will help you with depression). Good luck mate!
The brain is composed of a network of neurons that transmit signals by propagating nerve impulses. The propagation of this impulse from one neuron to another is typically controlled by neurotransmitters, though there are also electrical pathways between some neurons. Neurotransmitters can inhibit impulse firing (primarily done by γ-aminobutyric acid, or GABA) or they can excite the neuron into firing (primarily done by glutamate). A neuron that releases inhibitory neurotransmitters from its terminals is called an inhibitory neuron, while one that releases excitatory neurotransmitters is an excitatory neuron. When the normal balance between inhibition and excitation is significantly disrupted in all or part of the brain, a seizure can occur. The GABA system is an important target for anticonvulsant drugs, since seizures may be discouraged by increasing GABA synthesis, decreasing its breakdown, or enhancing its effect on neurons.[7]
I know, I know you’d think with all these side effects I’d just give up on ketosis! but I enjoy the mental clarity and I have a lot of food sensitivities and gut and yeast problems and don’t tolerate carbs well either so I feel stuck between a rock and a hard place. Not craving what I can’t have constantly is LIFE CHANGING! (34 year old female with chronic fatigue, thin, hike for exercise).
"One of the most amazing things that can happen is finding someone who sees everything you are and won't let you be anything less. They see the potential of you. They see endless possibilities.
