Keto flu symptoms and side effects can include feeling tired, having difficulty sleeping, digestive issues like constipation, weakness during workouts, being moody, losing libido and having bad breath. Fortunately, these side effects don’t affect everyone and often only last for 1–2 weeks. (And yes, you CAN build muscle on keto.) Overall, symptoms go away as your body adjusts to being in ketosis.
A one-ounce (28-gram) serving of olives contains 2 grams of total carbs and 1 gram of fiber. This works out to a net carb count of 1 gram for 7–10 olives, depending on their size. If you don’t like olives or don’t want the net carbs they contain, then olive oil is a great option as well. Although you won’t get all of the benefits of olives by consuming olive oil, you will still get plenty of healthy fats and health-promoting compounds.

"Plenty of people jump right in, thinking all they have to do is cut carbs and increase fat. All of a sudden, they hit a wall and get 'keto flu.' They feel tired, lethargic, and experience headaches," Wittrock says. "The primary reason they get these symptoms is lack of the three primary electrolytes: sodium, potassium, and magnesium. If you're deficient in any of these, you'll suffer mentally and physically. This is the single biggest reason people fail on the keto diet."
First, I want to thank you for all of your dedication and work in providing this site. The difficulty of maintaining a healthy weight is a big problem for so many people. My personal question & issue in staying on Keto is my craving for fresh fruit. This a.m I had a large fresh peach along with my “Bullet Proof” coffee. Have I now sabotaged today’s Keto eating?
If you’re new or just still learning the ropes for the keto diet food list, your biggest questions probably revolve around figuring out just what high-fat low-carb foods you can eat on such a low-carb, ketogenic diet. Overall, remember that the bulk of calories on the keto diet are from foods that are high in natural fats along with a moderate amount of foods with protein. Those that are severely restricted are all foods that provide lots of carbs, even kinds that are normally thought of as “healthy,” like whole grains, for example.
Reaction to eggs could be due to the following: Read Healthy Traditions website regarding chickens being fed soy – soy will be in the eggs. If you can’t get truly organic soy corn free eggs, you may order through them. It is said all soy, even organic is contaminated GE, plus it is said by reliable sources that organic soy, if consumed, should only be fermented. Non organic soy and corn are GE and heavily sprayed with diluted white phosphorus and flamydahyde (sp?) embalming fluid i.e. glousphate (sp) in Roundup Ready among other toxic chemical witch’s brews that farmers use requiring wearing hazmat suits.

This plan is very high on protein. I’ve learned that high healthy fat is what’s needed, not high protein.. as I am now kicked out of ketosis due to high protein intake (insulin’s fault). Given the fact i didn’t eat a bowl of salad per day (my tummy doesn’t digest salad well at all – i get bloated), but i do eat broccoli (i don’t get bloated from those strangely enough), cauliflower, asparagus, mushrooms… tomatoes (rarely, though). So, my question is… are you in ketosis following the menu you’ve presented? I’m 5 months into Keto and the last 3 weeks i am not in ketosis. My carb intake is 20-30g… but my protein is pretty high.
Avocados are loaded with heart-healthy monounsaturated fats, as well as fiber, which keeps your digestion running smoothly. This fruit can also help replenish electrolytes in the body. For example, a cup of avocado delivers 975 milligrams of potassium, a mineral that regulates fluid balance in the body. That’s extra important when you're on a very low-carb diet—this type of eating causes your body to excrete water and electrolytes, which can lead to dehydration, dizziness, and fainting.

If you are looking for a healthy cooking oil, extra virgin olive oil should be your staple. A recent study found this to be the healthiest oil for baking, cooking, and deep frying at high temperatures. This is because extra virgin olive oil contains a high-quantity of stable fats and antioxidants that protect the oil from breaking down into toxic chemicals.


Because people with type 2 diabetes are at an increased risk for cardiovascular disease, there’s a specific concern that the saturated fat in the diet may drive up LDL, or “bad,” cholesterol levels, and further increase the odds of heart problems. If you have type 2 diabetes, talk to your doctor before attempting a ketogenic diet. They may recommend a different weight-loss diet for you, like a reduced-calorie diet, to manage diabetes. Those with epilepsy should also consult their doctor before using this as part of their treatment plan.
What a great post. I thought i would add about the selection of food you eat on keto and that everyone is different. Some food gives you energy and some doesnt, this varies person to person. I started and quit keto 3 times before i managed to find my balance. The first few times it made be poorly, from the shock of diet change. However, you can wean yourself into the diet which i did the last time when i had the most success.
The original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories[Note 1] to maintain the correct weight for age and height. The classic therapeutic ketogenic diet was developed for treatment of paediatric epilepsy in the 1920s and was widely used into the next decade, but its popularity waned with the introduction of effective anticonvulsant medications. This classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains, and sugar, while increasing the consumption of foods high in fat such as nuts, cream, and butter.[1] Most dietary fat is made of molecules called long-chain triglycerides (LCTs). However, medium-chain triglycerides (MCTs)—made from fatty acids with shorter carbon chains than LCTs—are more ketogenic. A variant of the classic diet known as the MCT ketogenic diet uses a form of coconut oil, which is rich in MCTs, to provide around half the calories. As less overall fat is needed in this variant of the diet, a greater proportion of carbohydrate and protein can be consumed, allowing a greater variety of food choices.[4][5]
Technically this one should be part of the fruits section, but we won't tell if you won't! Avocados are such a top-notch keto food, due to their low-carb, high-fiber, and high-fat content that we thought they deserved to be called out separately. Research has shown that people who eat avocados tend to be healthier in general, and they're practically a must in a balanced keto diet.

Now, there’s even evidence that a low-carb, high-fat regimen (as the keto diet is) helps you live longer, compared to a low-fat diet. In a study by the medical journal The Lancet that studied more than 135,000 adults from 18 countries, high carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction or cardiovascular disease mortality.
A lot of people on the keto diet tend to go absolutely overboard with the unhealthy food that they pack into their plan. Sure a bunch of cheese, mayonnaise and bacon will fit into a seventy-five percent fat allowance, however, for your health these foods are not always the best option. Your day to day seventy-five percent fat allowance is meant to be used for healthy sources of fat such as such avocados, coconut oil, whole eggs, nuts and fats found in unprocessed meats such as beef, salmon, chicken thighs, ground pork or turkey.

A popular keto supplement are exogenous ketones (popularly called “keto diet pills”) that may help you achieve results earlier as well as remain in that state. (Don’t confuse exogenous ketones with raspberry ketones, as the latter don’t raise ketone levels in the body or mimic endogenous ketones, so you wouldn’t use raspberry ketones in your regimen.)
Keep an eye on your intake for nut or seed based foods, as they can be quite high in inflammatory omega 6’s. These include items like almonds, walnuts, pine nuts, sunflower oil and corn oil. Eating fatty fish and animal meat, keeping snacking to a minimum, and not over-indulging in dessert items that are dense in almond flour is usually enough to keep your omega’s at normal ranges. 

It prompts the question: why is this incredibly challenging, rigid, expensive diet so popular? One answer is the “modern caveman” narrative, as strong among keto advocates as it was with its paleo predecessor. This speaks to the compelling, but misplaced, notion that illness is simply a result of modern food processing practices and lifestyles, and can be reversed by returning to a simpler time. But a diet is a diet is a diet, and they all work the same way – by reducing the net amount of energy consumed. Keto diets may have a slight advantage, as the high fat intake is hypothesised to have satiating properties, helping you stay fuller for longer. But in reality, we have little evidence to show that keto is more effective in the long run than any other diet – or, indeed, that any diet succeeds in keeping off weight.
Thanks for the great article and helpful information about the Ketogenic diet .Since the last 4 years I’m on a keto diet I’m very happy,feeling a lot more healthy and I have lost a lot of weight.During that time I did quite few mistakes mainly due to misinformation so I highly recommend everyone who is really interested in keto diet to read this first

A computer program such as KetoCalculator may be used to help generate recipes.[47] The meals often have four components: heavy whipping cream, a protein-rich food (typically meat), a fruit or vegetable and a fat such as butter, vegetable oil, or mayonnaise. Only low-carbohydrate fruits and vegetables are allowed, which excludes bananas, potatoes, peas, and corn. Suitable fruits are divided into two groups based on the amount of carbohydrate they contain, and vegetables are similarly divided into two groups. Foods within each of these four groups may be freely substituted to allow for variation without needing to recalculate portion sizes. For example, cooked broccoli, Brussels sprouts, cauliflower, and green beans are all equivalent. Fresh, canned, or frozen foods are equivalent, but raw and cooked vegetables differ, and processed foods are an additional complication. Parents are required to be precise when measuring food quantities on an electronic scale accurate to 1 g. The child must eat the whole meal and cannot have extra portions; any snacks must be incorporated into the meal plan. A small amount of MCT oil may be used to help with constipation or to increase ketosis.[37]
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.
What makes this diet so special is that it changes how your body feels and most importantly how your body uses energy, placing you into a state known as ketosis. This is actually where all the magic begins to happen; in this state your body starts to utilize substances known as ketone bodies which are produced by the breakdown of your body fats. Your body loves glucose and if it has that on hand it’s going to use that first for energy. On the keto diet, the amount of carbohydrates decreases drastically, which in turn will lead to less production of glucose. High levels of glucose production is generally what makes you fat; without it, the body will begin to start breaking down your body fat and this is when you start to get leaner.

On your keto food list, stick to low-glycemic sweeteners to avoid spikes in blood sugar, and avoid fillers and binders such as maltodextrin and dextrose, which can spike blood sugar and contain sneaky carbs. Sugar alcohols such as maltitol or xylitol may read as no sugar on a label, but be aware that they will still cause moderate glycemic response when digested.


You're using it for a particular, short-term period.The meal substitute diet can function so quick and so well that you might decide to keep on following it for a longer while. You've acquired the flavor and habit of consuming the yummy meal substitute products that you think you'll stick to the program for a vague period. However, you need to understand that enduring high-calorie deficit in your system may not be good on an extended basis. Take advantage of the diet only as a boost to significant weight reduction or to be a procedure for a huge occasion arriving soon or under strict doctors monitoring.
Cyclical ketogenic diet (CKD): If you find it difficult to stick to a very low-carb diet every day, especially for months on end, you might want to consider a carb-cycling diet instead. Carb cycling increases carbohydrate intake (and sometimes calories in general) only at the right time and in the right amounts, usually about 1–2 times per week (such as on weekends).
Most people consider it a protein, but yogurt still contains some carbs in the form of the milk sugar lactose. How much, exactly, depends on the yogurt’s fat content. You’ll get around 16 grams of carbs in a cup of plain low-fat yogurt, compared to 11 grams of carbs in the same amount of whole milk yogurt. Flavored varieties have the most of all, thanks to all that added sugar. Believe it or not, some varieties of low-fat vanilla yogurt pack 31 grams of carbs.
