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.
There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
A simple standby, but one that ketoers adore. 2 or 3 fried eggs and some bacon might not sound like much, but it’s full of protein that will keep you full and energized all morning. Take the opportunity on the weekend to lay your bacon strips on a single cookie sheet and bake in the oven for 20 minutes at 400 degrees. The result is the best bacon you’ve ever had, in a big batch, with no sitting over a popping, hissing frying pan.
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.

Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.
These nachos use the trendy Fat Head pizza crust as the “nachos” with a Tex-Mex twist, substituting cilantro, cumin and chili for the rosemary and garlic in the pizza base. After you cut them into tortilla shapes, you’ll load them with a meaty sauce and finish off the nachos with your favorite toppings, like guacamole, jalapeños and salsa. They’re the perfect snack to enjoy with family on movie night.

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.
macronutrient ratios in line: "Fat should be used as a satiating nutrient. People don't necessarily need to eat fat bombs and put extra fat on their food or in their coffee just to make it high-fat," says Mavridis. While this is a good strategy for when you're transitioning from a glucose-dependent diet to a fat-fueled one, it's not necessary once you’re fat-adapted, she adds. This is where intuitive eating comes into play. Learn to pay attention to your hunger cues. "If you’re feeling hungry shortly after a meal then you probably did not have enough protein or fat. But if you’re full and satiated, there is no reason to consume excess quantities of fat," explains the health expert.
Keto diets rely on an extreme technique to (temporarily) move the scale down a few pounds, and basically eliminates all joy associated with eating real food and living life. Since restriction for life is downright impossible: Cut back on ultra-processed, high-carb foods like sugary beverages and tons of refined grains, and fill up on more nutritious carb choices, like veggies, fruit, legumes, low-fat dairy, and 100% whole grains to maximize long-term weight loss, health, and happiness.
Saturated fat is not harmful in the context of a low carb diet. This study from Johns Hopkins Medical School confirms this. The ketogenic diet plan is healthier because the higher saturated fat intake increases your HDL cholesterol, and at the same time, a lower carb intake decreases your triglycerides levels. These two factors are the major markers for heart disease, and the closer your triglyceride/HDL ratio is to 1, the healthier your heart. In reality, the cause of heart disease is a chronically high carbohydrate consumption, not a high saturated fat and cholesterol intake. I think the best way to learn this is to get a full blood test before you start a ketogenic diet plan, then do the diet faithfully for 3 months. Then have your blood work checked again. You'll see the difference and discover how much better you feel. 
If you’re not sure after your initial test, explore other healthy diets such as clean eating and always have in mind that your number 1 goal should be to avoid overly processed foods (keeping this definition fairly broad of course, as we live in the 21st century and have to adapt to modern age as well, where hardly any of us have time to spend 12 hours a day evolving around food production, gathering and cooking).
Hunger is one way to know if you’re in fat burning, because the longer you do keto, the less hungry you’ll be.39,40 If you’re getting severe hunger with weakness and brain fog, you’re not quite into keto. Back off a bit. Don’t be doing 20-hour fasts. You need more fuel to give your body the energy it needs, and that includes energy to manufacture the enzymes to burn fat instead of glucose. Take it slow, add more fat to your first meal, and eat nutrient-dense foods. If you need more nutrients, try adding some nutritional yeast and electrolytes, and major amounts of potassium. These will help you fix insulin resistance and help you get into fat burning. Bone broth is great for a snack. It’s just nutrients without calories, period.
When you consume lots of sugar and have higher levels of insulin on a continuing basis, your cells try to protect you and eventually start resisting or ignoring insulin. Remember, insulin is the key that allows glucose into the cell. So, your cells prevent insulin from working in order to prevent excessive sugar in the cell. This is your body saying, “If you’re going to keep eating sugar, I will block it at the cellular level.”
"Sunflower seeds are a great snack option whether you follow a keto diet or not," says registered dietitian Katey Davidson, M.S., R.D. Although all sunflower seeds are an excellent source of healthy unsaturated fats, protein, and vitamin E, many companies use flavorings to season their products which can be high in both salt and sugar, says Davidson. She recommends Terrasoul Superfoods because they aren't flavored or salted. And with only 6 grams of carbs and 1 gram of sugar (per one 1/4 cup), you won't have to worry about these seeds throwing you out of your hard-earned ketosis. However, Davidson says you'll want to aim to eat just a handful of seeds, which is considered a serving. (Related: This keto smoothie recipe is delicious even without a ton of fruit.)
Because the ketogenic diet alters the body's metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome,[34] which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in treating the seizures and some other symptoms in these diseases and is an absolute indication.[35] On the other hand, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria and other rare genetic disorders of fat metabolism.[9] A person with a disorder of fatty acid oxidation is unable to metabolise fatty acids, which replace carbohydrates as the major energy source on the diet. On the ketogenic diet, their body would consume its own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.[36]

However, ALSO be aware that most doctors get very little training on nutrition and don't understand the general effect of foods on the body. They are also taught that ketosis is dangerous, and so they know even less about ketogenic diets. Hence, if you ask your physician about this diet, you may get push back and a scary "ketosis-is-dangerous" sermon.
A short-lived increase in seizure frequency may occur during illness or if ketone levels fluctuate. The diet may be modified if seizure frequency remains high, or the child is losing weight.[18] Loss of seizure-control may come from unexpected sources. Even "sugar-free" food can contain carbohydrates such as maltodextrin, sorbitol, starch and fructose. The sorbitol content of suntan lotion and other skincare products may be high enough for some to be absorbed through the skin and thus negate ketosis.[30]
Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.
