Nuts or nut butters and seeds: Remember some nuts are fairly high in carbs (like peanuts, cashews, and pistachios). Stay away from any nut butters that have added polyunsaturated oils or “vegetable oils.” Choose higher fats choices, such as almonds or macadamia nuts, and seeds high in omega 3s like flaxseed and chia. Nuttzo is a great choice for a blend of good nuts. We, of course, make a delicious keto nut butter with MCTs and macadamia nuts.

I don’t normally eat a ton of eggs or chicken and stay mostly pescatarian. But I was trying to make an effort to eat more protein. Unfortunately I broke out in hives a few hours after forcing myself to eat the 2 hardboiled eggs provided for breakfast. Went to derm, who had me do a skin prick allergy test and lo and behold, allergic to eggs. (After 35 years on this earth eating the occasional omelette, and certainly many other things with eggs in them, this is surprise- but apparently eating an allergen on an empty stomach first thing is a great way to get the full effect of that allergen. Needless to say, I sadly threw out the rest of the eggs and my dog got a really nice couple of chicken & salmon dinners since I just could not stomach either after the first awful day. I’ve actually just ordered meta morphosis to reset after this Keto thing threw me off so badly. I do want to stress that I don’t fault Urban Remedy for this, I know Keto is trendy and they are responding to a diet plan that I know many people follow. I will continue to order, just never again this plan!
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.
That's because my intro to this seemingly new plan was when I worked in a hospital, where ketogenic diets were specifically used as a medical nutrition therapy for pediatric patients with seizure disorders, for whom medication was no longer effective. In other words: It was used as an absolute last resort for families who felt otherwise hopeless in the face of a neurological disease, and under strict medical supervision.
That’s why many health experts are concerned about people on the keto diet, especially those who try it without the guidance of a doctor or nutritionist. Doctors say that high-fat diets like this one may raise cholesterol levels, and some studies suggest that they increase the risk of diabetes. Some have even called it a “cardiologist’s nightmare.”
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.
People also see good weight loss results on the keto diet because eating a low carb, high fat diet can help you feel less hungry and not have to count calories or portion sizes to lose weight. Plus, cutting out the refined carbs and sugars normally present in a traditional Western diet helps avoid crazy spikes in blood sugar that can lead to the feeling of being hungry again soon after eating.
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 there is little carbohydrate 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. Almost 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. There is some evidence that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective. The most common adverse effect is constipation, affecting about 30% of patients—this was due to fluid restriction, which was once a feature of the diet, but this led to increased risk of kidney stones and is no longer considered beneficial.
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.
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
All low-carbohydrate vegetables contain essential vitamins, minerals, fiber and antioxidants that are beneficial for our health. Cruciferous vegetables come with an extra health boost. They contain more vitamin K and A than many other vegetables, this is the reason why we put cruciferous vegetables on the list of top keto foods. The reason why crucifers vegetables like broccoli and cauliflower are at an edge over every other vegetable is because of sulforaphane. Sulforaphane is a compound that is created when we crush or chew cruciferous vegetables. Once it is digested, sulforaphane activates a cytoprotective (cell-protecting) pathway that protects the cells from oxidative stress and removes harmful toxins from the body. This is one of the primary reason why cruciferous vegetable consumption is linked to improved cognitive function and decreased cancer and heart disease risk.
Your glycogen stores can still be refilled while on a ketogenic diet. A keto diet is an excellent way to build muscle, but protein intake is crucial here. It’s suggested that if you are looking to gain mass, you should be taking in about 1.0 – 1.2g protein per lean pound of body mass. Putting muscle on may be slower on a ketogenic diet, but that’s because your total body fat is not increasing as much.5Note that in the beginning of a ketogenic diet, both endurance athletes and obese individuals see a physical performance for the first week of transition.
