While macros will differ a little from person to person, the general rule of thumb for keto is to keep carbohydrates under 5% of your daily caloric intake. As long as you avoid the foods mentioned above, you should be fine. Google “TDEE calculator” if you need some additional guidance on how many calories to eat. I’ve had success following this way of eating as it allows me to eat foods that taste great. There are tons of resources online as well if you need additional guidance. A quick google search should turn up a ton of resources. Hope this helps!

But if your friends have gone #keto and you're curious about what that exactly entails, the basic premise is fairly simple. The diet focuses on eating mostly fat, limited amounts of protein, and almost no carbs at all. The "do" list includes: meat, seafood, eggs, vegetables that grow above ground, nuts and seeds, fats and oils, and some dairy products. In terms of drinks, most keto diet guides advise people to stick to water and skip diet soda, even though it's artificially sweetened. (No Diet Coke — sorry!)
All grains, even whole meal (wheat, rye, oats, corn, barley, millet, bulgur, sorghum, rice, amaranth, buckwheat, sprouted grains), quinoa and white potatoes. this includes all products made from grains (pasta, bread, pizza, cookies, crackers, etc.) sugar and sweets (table sugar, HFCS, agave syrup, ice creams, cakes, sweet puddings and sugary soft-drinks).
What we know today as keto was developed as a clinical tool more than 100 years ago. In 1911, doctors noticed that children with epilepsy stopped having seizures after two days of absolute fasting, the point when their bodies would have been forced into ketosis. Scientists later noted that ketosis could be achieved through a low-carb, high-fat (LCHF) diet without the risk of infection and mortality rates associated with absolute fasting. Today, children resistant to anti-epilepsy drugs still follow ketogenic diets to prevent seizures, under the management of specialist dietitians.
What is the ketogenic diet exactly? The classic ketogenic diet is a very low-carb diet plan that was originally designed in the 1920s for patients with epilepsy by researchers working at Johns Hopkins Medical Center. Researchers found that fasting — avoiding consumption of all foods for a brief period of time (such as with intermittent fasting), including those that provide carbohydrates — helped reduce the amount of seizures patients suffered, in addition to having other positive effects on body fat, blood sugar, cholesterol and hunger levels. (1)
Beyond being high in healthy fats, research has shown that people who include nuts in their diet are likely to live longer than those who don't. The right type of nut can be a great keto-friendly snack. The thing to remember with the keto diet is that you're looking specifically for low-carb, high-fat foods. Certain nuts meet this criterion and should be included in your keto meal plan in moderation. Listed in order of lowest to highest carb content per 1-ounce serving, the best nuts for the keto diet include:

Researchers believe that the ketogenic diet can also help patients with schizophrenia to normalize the pathophysiological processes that are causing symptoms like delusions, hallucinations, lack of restraint and unpredictable behavior. One study found that the keto diet lead to elevated concentrations of kynurenic acid (KYNA) in the hippocampus and striatum, which promotes neuroactive activity. Some studies even point to the elimination of gluten as a possible reason for improved symptoms, as researchers observed that patients with schizophrenia tended to eat more carbohydrates immediately before a psychotic episode. (19)


Keto breath, on the other hand, is less of a side-effect and more of a harmless inconvenience (your breath literally smells like nail polish remover). Basically, when your body breaks down all that extra fat on the keto diet, it produces ketones—one of which is the chemical acetone, Keatley previously told WomensHealthMag.com. (Yes, the same stuff that's in nail polish remover.)

“A lot of folks find that batch cooking once or twice a week saves a tremendous amount of time and keeps you from spending every evening in the kitchen,” Weaver says. “When keto meal planning, you want to follow general good meal planning practices, like shopping for the week’s food all at once, which helps to save money, and prepping your vegetables when you get home. These 10 keto recipes are so good you’ll forget you’re on a diet.


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.
It usually takes three to four days for your body to go into ketosis because you have to use up your body's stores of glucose, i.e., sugar first, Keatley says. Any major diet change can give you some, uh, issues, and Keatley says he often sees patients who complain of IBS-like symptoms and feeling wiped out at the beginning of the diet. (The tiredness happens because you have less access to carbs, which give you quick energy, he explains.)
The way that being on the keto diet makes you lose weight is by keeping insulin levels low. Insulin is a fat storage hormone that is released to help shuttle energy from the food you eat into your cells. This diet is known to be one of the best ways, besides fasting of course, to drop your insulin levels and low insulin is what is usually associated with fat loss. However, there is a misconception out there that your insulin will only go up with carbs. Protein can also spike your insulin levels and if you eat enough fats in one sitting, especially the wrong type of fats like trans fats, then that can spike your insulin levels as well.
“Eggs have a lot of vitamins like vitamin A, B complex, D, K, E, calcium, and zinc,” says Ryan Weaver, a personal trainer and keto enthusiast. “That’s why eggs are an excellent choice for breakfast when you follow the keto diet. To avoid getting bored, you can try different ways of preparing the eggs—boiled, fried, or baked. Also, you can combine the eggs with different foods like bacon, ham, cheddar cheese, butter, mayonnaise, so you get a different recipe each day although using the same main ingredient.”
Just because keto is a high fat diet doesn't mean you should rely on large portions of fatty meats to hit your daily fat quota. “It’s not about eating an 8-ounce steak,” Mancinelli says. “Instead, have a 3-ounce portion of steak with half an avocado on the side.” That’ll help you meet your fat needs without overdoing it on the protein or potentially harmful saturated fats.
I love this! I am an amateur powerlifter and I have recently started using the keto diet as there is only so much gained by being a fat powerlifter but working out my macros was driving me nuts as I also work as a disability support worker and need to take meals and so on to work with me. Thanks to this I can now have better control of the macros to bring my weight down without doing to much harm to my lifts! Thank you for this!
Remember, the point of the ketogenic diet is to enter ketosis by limiting your carbohydrate intake to about 5% of your total calorie needs and consuming about 75% of your calories in the form of fats. Vegetables and fruits naturally contain carbohydrates, and the ones included in the list above are lower in carbohydrates while not skimping on nutrients.

The best part of low carb eating is that you can still have rich, savory foods – dieting isn’t really a part of the lifestyle. Your body regulates your hunger naturally, so keeping your carbs low is the main concern. Being able to do that while still enjoying roast, fish, and big, healthy salads is what makes low carb so easy to stick with, and keep the weight off for good.

On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.

When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).


You want to keep your cheats to none. Be prepared, make sure you’re eating what you need to be satiated (“full”), and make sure you’re satisfied with what you’re eating. If you have to force yourself to eat something, it will never work out in the end. This is just a guideline on how you can eat on a ketogenic diet, so you’re very welcome to change up what kind of foods you eat!

If you’re a newbie planning your weekly keto diet menu, make the meals as easy as possible. A keto breakfast, for example, can take advantage of many classic breakfast foods, including eggs, bacon, sausage, and ham. Eggs are real winners in the keto world. They’re extremely versatile, easy to cook, and have just half a gram of carbs but 6 g of protein and 5 g of fat.
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.)

You might want to consider using a calprie counter/tool to help you determine the amount of calories, fat, protein, etc in food. I find MY Fitness Pal to be eztremely useful. You put in the type of food and it calculates all those tricky numbers for you. You can even see the macros (percentages) or set your own.it might seem a bit confusing at first but you’ll get the hang of it. Best of luck!

Long-term compliance is low and can be a big issue with a ketogenic diet, but this is the case with any lifestyle change.  Even though the ketogenic diet is significantly superior in the induction of weight loss in otherwise healthy patients with obesity and the induced weight loss is rapid, intense, and sustained until at least 2 year, the understanding of the clinical impacts, safety, tolerability, efficacy, duration of treatment, and prognosis after discontinuation of the diet is challenging and requires further studies to understand the disease-specific mechanisms.
The theory put forward is that, in ketosis, you adapt to use stored fat for energy more efficiently – but this is not borne out by research. “If you eat more fat, you’ll use more fat for energy,” says Alan Flanagan, a nutritional scientist. Published research to date has not shown any meaningful benefit to following a keto diet for athletic performance, he says; in fact, it may impede the ability to exercise at higher intensity.

They’re inexpensive, easy to make, and insanely versatile. And of course, they’re loaded with nutrition. The yolks are a top source of the mineral choline, which plays an important role in brain function, memory, metabolism, and mood, according to the National Institutes of Health (NIH). Eggs are also one of the few foods that deliver vitamin D, which can protect your eyes and bones, as well as promote healthy cholesterol levels.
Variations on the Johns Hopkins protocol are common. The initiation can be performed using outpatient clinics rather than requiring a stay in hospital. Often, no initial fast is used (fasting increases the risk of acidosis, hypoglycaemia, and weight loss). Rather than increasing meal sizes over the three-day initiation, some institutions maintain meal size, but alter the ketogenic ratio from 2:1 to 4:1.[9]
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.
No matter what your diet has been before now, keto will be a big change. If you're coming from a standard American diet (SAD), your carbs will go way down, your protein may either go up or down, and your fat will go way up. If you're coming from a bodybuilding-style diet, your fat intake will jump to alarming levels, and your protein will likely drop significantly.

In order to transition and remain in this state, aiming for about 30–50 net grams is typically the recommended amount of total carbs to start with. This is considered a more moderate or flexible approach but can be less overwhelming to begin with. Once you’re more accustomed to “eating keto,” you can choose to lower carbs even more if you’d like (perhaps only from time to time), down to about 20 grams of net carbs daily. This is considered the standard, “strict” amount that many keto dieters aim to adhere to for best results, but remember that everyone is a bit different.

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.[19] 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.[31]
