Sweeteners can be tricky on keto, but they do exist. Stick to low glycemic index sweeteners that won’t affect your blood sugar levels, and avoid sugar alcohols (even low or no-sugar ones). These include maltitol, dextrose or maltodextrin.
If you want to slam a protein shake post-workout, that’s probably fine as long as you’ve got room for it in your macros. But shoot for one that is very low—like, zero—in carbohydrates. If you struggle to fit fat in during the day, toss a tablespoon of olive oil in with your shake. You won’t taste it, and it gives a quick 13-14 grams of fat.
Since the glucose is being used as a primary energy, your fats are not needed and are therefore stored. Typically on a normal, higher carbohydrate diet, the body will use glucose as the main form of energy. By lowering the intake of carbs, the body is induced into a state known as ketosis.
An easy way to understand how your hormones work is to picture them as strands of a spider web: You can’t remove one strand without affecting the rest. In other words, when one hormone is out of balance, the rest are negatively impacted — but when the functioning of one hormone is improved, the rest are improved too.

As a precaution, you should always check with your physician if you have any concerns about starting a keto diet. You should especially be wary if you’re currently taking medications for a pre-existing condition as extra monitoring may be needed. Be careful when breastfeeding as you may need to increase carb intake.
For years and years, fat was seen as harmful for heart health and we were told to reduce them as much as possible. However, recent studies have debunked this, showing no significant link between saturated fats, which humans have been eating for thousands of years, and the risk of heart disease.
“Once your body enters ketosis, you also begin to lose muscle, become extremely fatigued, and eventually enter starvation mode. Then it actually becomes even harder to lose weight,” Cimperman told Healthline.
Start by using our keto macro calculator below to help you determine what and how much of each category to eat based on your specific body composition and lifestyle. You’ll have a rough estimate of how many grams of fat, protein and carbs your meals need to cover over the course of one day.
The most science-backed performance-boosting supplements, such as creatine monohydrate, beta-alanine, and caffeine, are all A-OK on the ketogenic diet. So, if you take a pre-workout, you should be able to continue without issue. I would also recommend gulping down some bouillon before your session to ensure your sodium and magnesium levels are on point.
The easiest macro to calculate in the ketogenic diet is fat. Once you’ve got your carbs and protein set, simply fill the rest of your daily calorie needs with fat sources. If you find yourself wanting to gain a bit of weight, add approximately 500 calories, or 55 grams. If you want to lose weight, cut down on your fat intake by 200-500 calories, or 22-55 grams.
The ketone bodies are possibly anticonvulsant; in animal models, acetoacetate and acetone protect against seizures. The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during a seizure, and may confer a neuroprotective effect.[55]
Option 3: Spicy guacamole with raw zucchini slices. The foods you choose between meals should still be keto-friendly and may even mimic an upcoming dinner, just in a smaller portion size, says Stefanski. “Since carbs are minimal, it’s important to spend your carbs on high-nutrient foods like vegetables.”
Studies show that aerobic endurance is not decreased with a ketogenic diet[*]. However, athletes who switch to keto might experience limitations in performance at the beginning. This is simply the body adjusting to using fat as its preferred energy source.
Possible therapeutic uses for the ketogenic diet have being studied for various neurological disorders in addition to epilepsy: Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS), autism, brain cancer, headache, neurotrauma, pain, Parkinson’s disease (PD) and sleep disorders.[6]
Drinking alcohol slows ketone production. There are some legitimate concerns when it comes to consuming alcohol on a ketogenic diet. Alcohol slows fat burning and ketone production. Drinks to avoid include:
The Johns Hopkins Hospital protocol for initiating the ketogenic diet has been widely adopted.[42] It involves a consultation with the patient and their caregivers and, later, a short hospital admission.[18] Because of the risk of complications during ketogenic diet initiation, most centres begin the diet under close medical supervision in the hospital.[9]
It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients.[22] It concluded that a third achieved a excellent reduction in seizure frequency and half the patients achieved a good reduction.[3]
When implementing any new diet — not just keto — it’s important to do so safely, and in a way that supports your unique lifestyle. With this in mind, here are two potential side effects you should know about:
During HPA axis dysregulation, cortisol can become abnormally high. If it remains high, the body will develop cortisol resistance. To compensate the body begins to secrete higher amounts of adrenaline which can then cause irregular heart rhythms.
Net carbs are used because dietary fiber does not have a significant metabolic effect. We are trying to get as accurate of a picture as possible when tracking macros, therefor net carbs is what makes the most sense.
Lauren Ciccarelli is a writer and former carb addict. Since going keto, she not only lost 35+ pounds and banished her PCOS symptoms, she also found more energy to be awesome and less distaste for lifting weights. Say hi to her on Twitter @ciccarelli.
Restrict your protein intake. Many people come over to keto from an Atkins diet and don’t limit their protein. Too much protein can lead to lower levels of ketosis. Ideally for weight loss, you want to eat between 0.6g and 0.8g protein per pound lean body mass. To help with this, consider using the keto calculator >
Targeted: On a targeted keto diet, you consume carbohydrates around your workouts to improve athletic performance without knocking yourself out of ketosis for too long. This version is also geared toward hardcore exercisers.
This week we’re getting stricter with our fasting. We had a full week of intermittent fasting and now we’re going to skip breakfast and lunch. Water is our BEST friend here! Don’t forget that you can drink coffee, tea, flavored water, and the like to get your liquids in. Keep drinking to make sure you’re not thinking about your stomach. It MIGHT start growling, just ignore it – your body will adjust with time.
Glucose will always be your body’s preferred energy source. When glucose is present, your body will resist burning fat. By removing carbohydrates and replacing them with fat, you are forcing your body to burn that fat for fuel.
Ketosis is actually a mild form of ketoacidosis. Ketoacidosis mostly affects people with type 1 diabetes. In fact, it is the leading cause of death of people with diabetes who are under 24 years of age.
On the other hand, the types of foods you’ll avoid eating on the keto, low-carb diet are likely the same ones you are, or previously were, accustomed to getting lots of your daily calories from before starting this way of eating. This includes items like fruit, processed foods or drinks high in sugar, those made with any grains or white/wheat flour, conventional dairy products, desserts, and many other high-carb foods (especially those that are sources of “empty calories”).
Armed with knowledge, your keto food list and plenty of keto recipes, you should be ready to give the keto diet a try! Once your body adjusts, you’ll see increased energy levels, rapid fat burning and all the positive effects that come with ketosis.

But now, I just treat carbs as my drug. Obviously it’s damn near impossible to just have 0 carbs every day, but keeping it under 20g allows me to basically be carb abstinent. It allows me the freedom to eat other foods without feeling guilty or scared. I hate to be hyperbolic, but I really believed that keto may have saved my life. I was heading in a really bad direction and now I can’t see myself ever going in a different one.
Wrong. Not just a no, but a HELL no. I cannot believe how just unappetizing and disgusting that soda was. After decades of drinking soda on a daily basis, I was convinced it was delicious. And now, only a little over a week of keto, and I can barely stomach the stuff.
