That can be a shock to the body. “One of the challenges that many people encounter when they try the ketogenic diet for the first time is the drastic lack of energy that is experienced in the first few days. This is the time when the body is learning to use fat for energy rather than readily available carbs,” says Susan Kieffer, DBA, the department chair for the School of Nursing at Purdue University Global. “You can feel very tired during this time and even a little fuzzy in your thinking.”
Also make sure that you know what foods have mostly carbs, fat, and protein, so you can make the right choices. For instance, it’s not just bread, pasta, chips, cookies, candy, and ice cream that contain carbs. Beans may contain protein, but they’re also very high in carbohydrates. Fruit and veggies also mostly contain carbs. The only foods that don’t contain carbs are meat (protein) and pure fats, like butter and oils.

As ketones levels rise in the body, the cells of heart, brain and muscles begin to use them for fuel. And once the body is using ketones as a main fuel source, there are some profound and positive health effects.  Ketogenic diets are very effective for correcting cellular metabolic dysfunction. The high blood sugar of diabetes gets reversed, the seizures of epilepsy can be calmed, Alzheimers and Parkinsons symptoms are alleviated, extra weight can be lost, joint pain is diminished and so on.  In other words, the ketogenic diet is not a “fad.” It is a potent regulator of metabolic derangement, and when formulated and implemented correctly, it can be extremely effective at reversing all kinds of health problems.

So, the other day I bought some broccoli and I was staring at the stems thinking "I know I can do something besides just slice and sauté these (I am aware that people rice them, but now that bagged frozen riced cauliflower is a thing I will never rice anything again) I pulled out my mandolin and sliced them up figuring i could ten sauté or do something else, and then realized that they were the perfect "Chip" size! First I ate some raw with labne (yogurt cheese) Delicious! Very good option for when you want to dip something! Then today decided to try frying them...
Thank you for this honest post on how Keto affected you. I did Keto for 6 weeks. I did lose 7 lbs but I struggled with depression and not using the bathroom regularly nice I started the diet. I searched and found carbs help with serotonin uptake which explained my depression. Everywhere I look people are pro Keto instead of discussing some the side effects. My gym friend told me she cried the last 4 days she did Keto before saying enough is enough. If it works for others, that’s great, but it’s refreshing to hear that I am not the only one who struggled and stopped Keto.

Many neurological conditions share a common feature of impaired brain energy metabolism. It isn’t always clear if this impairment is the cause or the effect of the disease, but nonetheless, interventions that even partially restore or improve brain energy metabolism could help to prevent, slow or even reverse some conditions of the brain. Because ketones can: 1) get into the brain; 2) undergo metabolism by a distinct pathway that bypasses glucose metabolism, providing ketones by either following a ketogenic diet or by taking exogenous ketones could impact the natural course of some neurological conditions. 

"I'm not obsessed with food anymore. Before keto, I was constantly hungry and thinking about food. If we got takeout, I would open all of the containers to see which one had the most in it and I would grab that one. It makes sense now because everything I was eating was full of sugar and carbs and I was in that vicious cycle. Growing up, if we had a bad day my dad would say, "Let’s go get some ice cream." He wasn’t trying to raise a food addict.


C8 is the rarest MCT found in coconut oil, comprising about 6% of coconut oil. It has potent anti-microbial properties (way more potent than lauric acid) to help you maintain a healthy gut, and it is the fastest MCT to metabolize in the brain. (hence the name Brain Octane). Your liver does not need to process C8, and it only takes the steps for your body to turn it into ATP cellular energy (sugar takes 26 steps). You would need 18 tablespoons of coconut oil to get just one tablespoon of Brain Octane.
An increase in fat burning ability could improve endurance capacity: as body fat represents a larger store of energy (150,000 kCal) compared to carbohydrate (2000 kCal), a greater ability to burn fat during exercise could prolong endurance performance. Whilst the theory appears sound, there is only one study showing an IMPROVEMENT in performance with a low carbohydrate diet18, with many showing no clear benefit of a low carbohydrate diet 19 ,20.    
"Growing up, I was always sick to my stomach and doctors couldn’t see anything wrong. After going keto, all those symptoms went away, until I have a cheat meal. For the first year, I didn’t have any cheats. Now, 95 percent of the time it’s keto, but if we go on vacation or have an anniversary, I’ll have a cheat meal. I usually don’t feel good after cheating and I remember why I don't like to do it."  
Check the nutrition labels on all your products to see if they’re high in carbs. There are hidden carbs in the unlikeliest of places (like ketchup and canned soups). Try to avoid buying products with dozens of incomprehensible ingredients. Less is usually healthier.Always check the serving sizes against the carb counts. Manufacturers can sometimes recommend inconceivably small serving sizes to seemingly reduce calorie and carb numbers.
Under these circumstances, as soon as the body’s limited reserves of glucose starts to run out, your entire body switches its fuel supply to run almost completely on fat. The levels of the fat-storing hormone insulin levels become very low, and fat burning increases dramatically. You thus get easy access your fat stores, and can burn them off. This is great for losing excess weight. Studies prove that keto diets result in more weight loss, faster. There are also more potential benefits.
Ketosis is really a shortening of the term lipolysis/ketosis. Lipolysis simply means that you're burning your fat stores and using them as the source of fuel they were meant to be. The by-products of burning fat are ketones, so ketosis is a secondary process of lipolysis. When your body releases ketones in your urine, it is chemical proof that you're consuming your own stored fat. And the more ketones you release, the more fat you have dissolved.

Someone trying to follow the keto diet to a letter may not even go into the much-desired state of ketosis. Sure, you can buy those little piss strips that react to ketones in your urine to reassure you that you’re “in ketosis,” but you’re probably wasting your money. Ketones are present in low levels in your urine even if you’re not on a ketogenic diet. Measuring ketones via blood is far more accurate (if not overly invasive for a diet), but to measure them for weight loss in the first place is borderline useless, especially in urine.
Cancer is a broad term that refers to the presence of abnormal cells in the body that have the potential to grow and spread to other sites in the body. Cancer develops over time as cells acquire defects that affect their function, growth, proliferation and metabolism. Recently a list of ‘Hallmarks of Cancer’ was proposed by some of the leading investigators, Hannahan and Weinburg90 . These hallmarks include:

If you’re looking to get a jump start on your health and fitness goals this year, you may be thinking about trying the ketogenic diet. Maybe you’ve heard the phrase before — it’s a huge diet buzzword — but aren’t sure what it means. Here’s a primer: The ketogenic diet is an eating plan that drives your body into ketosis, a state where the body uses fat as a primary fuel source (instead of carbohydrates), says Stacey Mattinson, RDN, who is based in Austin, Texas.
Now you’ve made the decision to follow the diet, it’s time to choose the type. There are four options. The standard ketogenic diet is the ones that we’ve already looked into, where your diet consists of 70% fat, 25% protein and the rest carbs. You can also follow a high protein option, which cuts your fat intake to 60% and your protein intake up to 35%.

“Instead of engaging in the next popular diet that would last only a few weeks to months (for most people that includes a ketogenic diet), try to embrace change that is sustainable over the long term. A balanced, unprocessed diet, rich in very colorful fruits and vegetables, lean meats, fish, whole grains, nuts, seeds, olive oil, and lots of water seems to have the best evidence for a long, healthier, vibrant life."

In fact, most folks have enough stored body fat to fuel aerobic activity for days and days without running out of energy. For example, a 150 pound dude at a hot, sexy and ripped at 8% body fat still carries 12 pounds of storage fat – which at 3500 calories per pound of fat can easily liberate 42,000 calories of useable fuel for exercise. You’ve got those same thousands of calories sitting around your waist, abs, hip, butt and thighs – just sitting there, waiting to be burnt.


At the end of the twelve months, 60 participants (about 82%) in the low-fat group and 59 participants (about 79%) in the low-carbohydrate group successfully completed the trial. The decrease in body weight was substantially greater in the low-carbohydrate diet group which lost four times as much weight as the low-fat group (1.1 kg vs. 4.4 kg). [18]
Ketone esters (BHB-BD) could help to accelerate glycogen resynthesis32. After exercise that depletes muscle glycogen, the muscle uses carbohydrate from the diet to replenish these stores. An experiment was carried out where athletes undertook depletive exercise and then were given a ketone drink (or carbohydrate placebo) as well as glucose intravenously to maintain a high blood level (10mM). In this experiment, when the recovery drink contained ketone ester, more glucose was infused in order to maintain blood glucose at 10 mM, and muscle glycogen levels were 50% higher. However, the evidence is not conclusive: another study. 31 found that adding ketone ester to a protein and carbohydrate recovery drink did not enhance the normal rate of glycogen re-synthesis.  
A reduced availability of dietary carbohydrates leads to an increased liver production of KBs. The liver cannot utilize KBs because it lacks the mitochondrial enzyme succinyl-CoA: 3-ketoacid (oxoacid) CoA transferase (SCOT) necessary for activation of acetoacetate to acetoacetyl CoA. KBs are utilized by tissues, in particularly by brain. KBs enter the citric acid cycle after being converted to acetyl CoA by hydroxybutyrate dehydrogenase (HBD), succinyl-CoA: 3–CoA transferase (SCOT), and methylacetoacetyl CoA thiolase (MAT). Modified from Owen (2005), Paoli et al. (2014).
As is in the case of GABA, the intracellular reactive oxygen species (ROS) hypothesis works against the hunger-suppressive role of KD: it has been demonstrated that the hypothalamic ROS increase through NADPH oxidase is required for the eating-inhibitory effect of insulin (Jaillard et al., 2009); moreover it has been demonstrated that there is a ROS-dependent signaling pathway within the hypothalamus that regulates the energy homeostasis, and that activation of ROS-sensitive mechanisms could be sufficient to promote satiety (Benani et al., 2007). On the other side, KBs decreases mitochondrial production of ROS by increasing NADH oxidation in the mitochondrial respiratory chain (Maalouf et al., 2007).

This was a great post. I did Keto last year, really strictly, and dropped 13 lbs in about 3 weeks. Then the holidays came and I had cookies. I’ve struggled since then to get back into the Keto mode. I do well for a few days, drop a few lbs and then have a “bad” weekend and back up I am. I’ve literally been gaining and dropping the same 5 lbs. for a year. I also miss certain carbs. I love bread and homemade bread can be healthy. I miss yams and beans, etc. I’m beating myself up because I want these foods I’ve eaten my entire life and now “can’t”. I appreciate your comments about accepting and loving our bodies no matter what size. Yes, I want to be healthy but I’m tired of obsessing about every single thing that I put in my mouth. This article is inspiring.
It is interesting to note that the KB are capable of producing more energy than glucose due to the changes in mitochondrial ATP production induced by KB (Kashiwaya et al., 1994; Sato et al., 1995; Veech, 2004). During fasting or KD glycaemia, though reduced, remains within physiological levels (Seyfried and Mukherjee, 2005; Paoli et al., 2011). This euglycemic response to extreme conditions comes from two main sources: glucogenic amino acids and glycerol liberated via lysis from triglycerides (Vazquez and Kazi, 1994; Veldhorst et al., 2009). Glucogenic amino acids (neoglucogenesis from amino acids) are more important during the earlier phases of KD, while the glycerol becomes fundamental as the days go by. Thus, the glucose derived from glycerol (released from triglyceride hydrolysis) rises from 16% during a KD to 60% after a few days of complete fasting (Vazquez and Kazi, 1994). According to Bortz (1972) 38% of the new glucose formed from protein and glycerol is derived from glycerol in the lean while 79% in the obese (Bortz et al., 1972). It is important to note that during physiological ketosis (fast or very low calorie ketogenic diets) ketonemia reaches maximum levels of 7–8 mmol/L with no change in blood pH, while in uncontrolled diabetic ketoacidosis blood concentration of KBs can exceed 20 mmol/L with a consequent lowering of blood pH (Robinson and Williamson, 1980; Cahill, 2006) (Table ​(Table11).
Although convincing, the bulk of evidence in relation to the inhibitory effects of ketosis on appetite is still anecdotal. Preliminary scientific reports seem to support this phenomenon, and the evidence shows that KD is more effective, at least in the short/medium-term, on fat loss (Paoli, 2014). It was demonstrated that diet-induced weight loss leads to changes in energy expenditure and in appetite-regulating hormones that facilitate weight regain and the return to initial energy homeostasis (Sumithran et al., 2011). This response to alteration of energy balance nullifies the success of many dietary approaches. It is well-known that the long-term success of a nutritional approach is defined by the amount of weight regain and is the main problem regarding the so-called weight cycling or “yo-yo” effect (Jeffery, 1996). A recent study by our group has demonstrated that a brief ketogenic period, if followed by a longer period of correct Mediterranean diet could avoid this yo-yo effect (Paoli et al., 2013). During the ketogenic period subjects reported less hunger, confirming previous studies (Nickols-Richardson et al., 2005; Johnston et al., 2006; Johnstone et al., 2008) on hunger-suppression effect of ketogenic diet. Despite these clinical findings, the mechanisms of action of ketosis on appetite reduction are still not completely understood. Clinical results are suggestive of both direct and indirect (via modifications of hunger-related hormones concentration) actions of KBs on appetite (Sumithran et al., 2013).

Other research further supports the benefits of this diet. For example, the ketogenic diet has been linked to reduced symptoms of Alzheimer’s disease. (4) It may also help manage Parkinson’s disease, control seizures in children with epilepsy, and, according to the results of a small pilot study, may even improve symptoms of polycystic ovary syndrome (PCOS). (5, 6, 7)

Studies also contradict the claim that the ketogenic diet will help your Crossfit performance, or whatever. A 2018 study published in The Journal of Sports Medicine and Physical Fitness reports that a low-carb diet inhibited cardiovascular performance. Want to check that half marathon off your bucket list? Science says eat your carbs. Multiple studies have shown similar results. The best news I can tell you about keto is that a 2017 Journal of Human Kinetics study said that it can help maintain a lower body weight, which can help athletic performance. But the study also said that “some aspects regarding the effects of long-term LCHF diets in athletes are still unexplored and in need of investigation, including (...)Strength, power, psychological status, and perceptual-motor performance after weight loss.” So, take that with a grain of low-carb salt.

Transformation Tuesday::: I wore shorts once last year, i felt good because they were a size 16 I think, down from a size 20. My size 2 shorts in the after picture are now too big. About a year between these pictures and at least 100lbs. I was working out, but @coach_jmo had just had the food conversation with me. It was vacation time and I was sad about not being beach ready in a little over 3 months. 😂 I was still making bad choices to help me cope with my weight gain from Postpartum depression and anxiety. I was still eating horribly, with cheat weekends and lots of pizza. 😂 I still thought exercising was enough to help me reach my goals. Working out 7 days a week with my trainer and a Ketogenic diet have changed my life. Down from a size 18/20 to a Size 0/2, over 130 pounds, and over 115 inches. 🎉🙌🎊
