Here are a few of the most common side effects that I come across when people first start keto. Frequently the issues relate to dehydration or lack of micronutrients (vitamins) in the body. Make sure that you’re drinking enough water (close to a gallon a day) and eating foods with good sources of micronutrients. To read more on micronutrients, click here >

Insulin triggers include carbohydrates, sugars, excessive protein. Also, every time you eat, you trigger insulin – unless you eat fat only. Combining certain foods, in fact, really spikes insulin, such as combining protein with sugars—so meat with bread, meats with sugary condiments like ketchup, barbeque sauce, sweet chili sauce and chicken fingers—these are deadly for the blood sugar and really spike insulin like birthday cake. Also, certain compounds in fast food really spike insulin, especially MSG, which is added to all kinds of fast foods, not just Asian food.
Beef Pemmican — Pemmican is a delicious paste of dried and pounded meat mixed with melted fat and other ingredients, originally made by North American Indians and later adapted by Arctic explorers. It is an undeniably delicious keto snack if you want something that is filling with beefy flavor. I recommend getting your pemmican from U.S. Wellness Meats. Opt for the Honey & Cherry-Free Beef Pemmican.
As a result of those satiating fats required by the ketogenic diet, you may find you’re not craving snacks as much as you usually do. “I find people who follow the ketogenic diet, they’re just not as hungry, so their snack frequency comes down,” says Dina Griffin, RDN, with eNRG Performance in Littleton, Colorado. “There’s just so much fat in their diet, so they say, ‘I don’t want to eat again,’ or ‘I can’t, I’m just not hungry.’”

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.

Some ingredients you will already have in your cupboards like seasonings and condiments.  We list these out at the beginning of the meal plan.  We assume that you'll have them in stock.  If you're worried you won't have them all, you can check the meal plan for the daily ingredients as well!  There are also some rare ingredients that we suggest you purchase at the beginning of you ketogenic diet journey.  You'll begin to use these low carb ingredients in more and more of your keto diet recipes.  You can get bargains on items such as almond flour if you purchase ahead online instead of waiting to purchase at the grocery store.  In addition, you won't have to wander the health stores for hours in search of these items to find out they don't stock them, or that they are ridiculously over-priced.

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]
Vicky started Tasteaholics in 2015 with her boyfriend, Rami, hoping to document all their low carb cooking adventures. She lives in NYC and her favorite food is steak and lava cake. She enjoys photography, travel, cooking, working out, cats & Harry Potter. She loves sharing her knowledge, cooking tips and creative dishes with all of Tasteaholics’ readers.
It may seem like the internet is constantly buzzing about the reported health benefits of the keto diet, but it's important to acknowledge that the diet can have some consequences for your health if it's done incorrectly. To avoid unwanted keto fails, we spoke to experts about fixable keto-diet mistakes to keep in mind if you're serious about giving the diet a try.
Potatoes and gravy are total comfort food — and luckily, there’s a keto version. These are made with cauliflower, which is quite low-carb, particularly when compared to potatoes. Made with cream, butter, rosemary and parmesan, this mash is creamy, full of flavor and smooth. You’ll finish it all off with a stock-based gravy, that would be perfect on a roast, too.
Ketosis takes some time to get into – about two weeks of low carb eating is required for the initial adaptation. During this time there will be bouts of sluggishness, fatigue, headaches, and some gastrointestinal issues as you adapt, often referred to as “keto flu“. Proper electrolyte intake will correct most of these issues. In addition, the “diet” aspect of this ketogenic diet plan – that is, the caloric restriction – shouldn’t be worried about. Weight loss will come as your body regulates appetite as it the addiction to sugar and processed food lessens, so restricting calories during the initial two weeks isn’t recommended.

Following the ketogenic diet can be safe in the short term but it does come with health concerns. 'It's not something that I recommend for the general population for the long-term,' says Dr Barclay. 'By drastically cutting out carbohydrate-containing foods, you'll miss out on the nutritional benefits of healthy choices like whole grains, fruit, starchy vegetables, and legumes such as beans, chickpeas and lentils.'
Wow!! This was sooo good! Tried another crack chicken recipe with a ranch packet and had to throw away the leftovers…no one would eat them. This, however is much better!! Didn’t change recipe other than use pre cooked bacon that I cut up. Probably would be better with the grease involved, however, this is AWESOME!! Also, my chicken tenders were still 3/4 frozen and I didn’t adjust time. They were just fine. Thanks for sharing!! A def do over say myself, hubby, and kids!!!
Switching to a ketogenic diet plan can be uncomfortable at first because your body metabolism is refitting itself to burn fat instead of relying on glucose.  However, you can avoid most of the symptoms. Here's a list of all of the common side effects that will happen the first week or so of starting a ketogenic diet. Knowing about them allows you to take steps to minimize them, and save yourself some carb withdrawal misery. Dr. Mike Eades has a great analogy for this process in this blog post.  I highly recommend you read it.
A systematic review in 2018 looked at sixteen studies on the ketogenic diet in adults. It concluded that the treatment was becoming more popular for that group of patients, that the efficacy in adults was similar to children, the side effects relatively mild. However, many patients gave up with the diet, for various reasons, and the quality of evidence inferior to studies on children. Health issues include high levels of low-density lipoprotein (LDL), high total cholesterol, and weight loss.[23]
"I recommend designing the meal around the fat and protein sources, since the carbohydrates are very limited. For example, if someone is having tuna for lunch, they may consider adding mayo to it. I also think a common mistake made on the diet, is individuals focus on reducing carbohydrates, but they do not increase their fat adequately. This may make it difficult to go into ketosis, especially if they are consuming too much protein. Some adults can be on a stable ketogenic diet consuming 50 net carbs whereas some may need to restrict to 15 net carbs."
For patients who benefit, half achieve a seizure reduction within five days (if the diet starts with an initial fast of one to two days), three-quarters achieve a reduction within two weeks, and 90% achieve a reduction within 23 days. If the diet does not begin with a fast, the time for half of the patients to achieve an improvement is longer (two weeks) but the long-term seizure reduction rates are unaffected.[43] Parents are encouraged to persist with the diet for at least three months before any final consideration is made regarding efficacy.[9]
You’ll quickly find that eggs are a staple for breakfast in low carb diets. Eggies are a simple solution for days of healthy breakfasts. Simply beat 8 eggs in a bowl, add in cheese and vegetables, and pour into muffin tins that have been lined with a strip of bacon. Cook at 350 for 30 minutes, or until a toothpick stuck in the middle comes out clean. Store in baggies for breakfast for up to 5 days.
The first modern study of fasting as a treatment for epilepsy was in France in 1911.[12] Twenty epilepsy patients of all ages were "detoxified" by consuming a low-calorie vegetarian diet, combined with periods of fasting and purging. Two benefited enormously, but most failed to maintain compliance with the imposed restrictions. The diet improved the patients' mental capabilities, in contrast to their medication, potassium bromide, which dulled the mind.[13]
I want to give special mention one of the side effects of carb withdrawal because it can really be scary if you don't know what it is.  During the first week or so of cutting your carb intake, your blood sugar levels will fall, and you may experience a mild insulin overload and reactive hypoglycemia.  This usually happens to people who are severely insulin resistant.  It takes about 2-3 days to burn through all of your stored glycogen (carb energy stored in your muscles and liver), and after that you may get these low blood sugar symptoms of shakiness, dizziness, tremors, a pounding heart and more. (See the link above for more info). For those of you that have been living on a high-carb diet for a long time, the effects may be even more pronounced, as your blood sugar and insulin levels are probably chronically high.  
The wildly popular Crack Chicken is actually pretty simple in its ingredient list: chicken, cream cheese, cheddar cheese, bacon, scallion, and Ranch seasoning! The end result is creamy and rich, and packed with flavor. It’s proof that a recipe doesn’t have to be complicated to taste great. Crack Chicken is deliciously addictive, which is where the name comes from.
Because some cancer cells are inefficient in processing ketone bodies for energy, the ketogenic diet has also been suggested as a treatment for cancer.[58][59] A 2018 review looked at the evidence from preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumour effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumour effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tend to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers.[60]
When you’re burning more ketones, you can start releasing a bit of acetone, which smells like nail-polish remover. Or you might release ammonia. Sometimes you get that sulfur smell. For all of these, increase vegetable consumption. Over time, you’ll be more efficient at burning ketones, and a lot less of this will happen. If you’re getting an ammonia smell, it means you’re eating too much protein and need to cut back. A sulfur odor means there’s a gut issue, and you need to regulate your gut bacteria; you should take a type of probiotic called Pro EM-1, which you can find online.
The problem is that, with a bit more time, the pancreas eventually stops compensating, becomes exhausted, and makes less and less insulin—allowing the sugar in your blood to go higher and higher. So, the first stage of insulin resistance is normal or low blood sugars due to excessive compensation of insulin. Then this is followed by higher and higher blood sugars as you lose the ability to compensate for the sugar with insulin. This is called diabetes.
Think about what’s happening. Your cells are resisting insulin, causing your body to make a lot more. With all this extra insulin in your blood, you could experience low blood sugars. This is called hypoglycemia, a word made from hypo (low) and glycemia (glucose in the blood). Hypoglycemia is caused by too much insulin in the blood and is a prediabetic symptom. Signs of hypoglycemia include cravings for carbs and sweets, being irritable, moody or depressed, having vision problems, being hungry or dizzy, and the list goes on and on. Your brain is the first organ to feel the effects of low blood sugars.

One cup sliced cucumbers and 10 large olives makes for a great keto-friendly snack, with added benefits: “This is a great snack to help people in ketosis supplement their sodium levels." says Desiree Nielsen, R.D., author of Un-Junk Your Diet. When you're in ketosis, your body needs more sodium, and “without adequate sodium, people are at risk for dehydration, constipation, and more dangerous electrolyte imbalances," she adds.
Raw Coconut Butter — This is made from blended coconut meat, and provides us with a delicious way to get plenty of coconut fat without missing out on our favorite coconut flavors. Make sure the coconut butter you find has no added sugar — and, most importantly, don’t overdo it. Coconut butter is packed with calories which can slow your weight loss.
Low carb diets focus on keto recipes (also known as ketogenic recipes) like the ones below to keep your blood sugar stable, helping your body regain insulin sensitivity and keeping your mood and energy levels stable. Also, since processed food has so many additives – usually sugar included – low carb diets encourage you to cook for yourself. This leads to eating more whole foods and improving your diet in that way as well.
Try Googling “TDEE Calculator”. Once you plug in your stats, the site will calculate your total daily energy expenditure. This is a useful guide in determining how many calories to eat. From there, if you are trying to lose weight, just reduce your caloric intake, increase your expenditure (through exercising more), or use a combination of the two.

This is the only way my kids will eat Brussels sprouts! It’s actually great for me because this dish is fast, easy and healthy, and it makes a lovely side. Quick-cooking Brussels sprout halves are available in the prepackaged salad aisle at the grocery store. They’re a timesaver if you can find them, but you can always just buy whole ones and slice them in half. —Teri Rasey, Cadillac, Michigan
The ketogenic diet is a medical nutrition therapy that involves participants from various disciplines. Team members include a registered paediatric dietitian who coordinates the diet programme; a paediatric neurologist who is experienced in offering the ketogenic diet; and a registered nurse who is familiar with childhood epilepsy. Additional help may come from a medical social worker who works with the family and a pharmacist who can advise on the carbohydrate content of medicines. Lastly, the parents and other caregivers must be educated in many aspects of the diet for it to be safely implemented.[5]
If you haven't heard of biltong, they're those thick, flavorful strips of air-dried meat that put stringy, chewy, and additive-packed beef jerky to shame. These peppery little slabs are made from grass-fed beef, air-dried for 14 days, and spiced with a blend of cayenne and chili powder to add some heat without overwhelming your palate. They’re also sugar-free, full of protein, and super simple to toss in your bag.
One downside to a ketogenic diet for weight loss is the difficulty maintaining it. “Studies show that weight loss results from being on a low-carb diet for more than 12 months tend to be the same as being on a normal, healthy diet,” says Mattinson. While you may be eating more satiating fats (like peanut butter, regular butter, or avocado), you’re also way more limited in what’s allowed on the diet, which can make everyday situations, like eating dinner with family or going out with friends, far more difficult. Because people often find it tough to sustain, it’s easy to rely on it as a short-term diet rather than a long-term lifestyle.
