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.
The main criticisms include fears about fat intake and the process of ketosis.The argument over whether saturated fats are unhealthy has been settled in the research literature (they are not). If you need more info, there are several good books to read on this subject.  For more information about the type of fats to eat, see the saturated vs unsaturated fats page.  The right side column on that page has books which provide more information.
The ketogenic diet is not a benign, holistic or natural treatment for epilepsy; as with any serious medical therapy, there may be complications.[27] These are generally less severe and less frequent than with anticonvulsant medication or surgery.[27] Common but easily treatable short-term side effects include constipation, low-grade acidosis and hypoglycaemia if there is an initial fast. Raised levels of lipids in the blood affect up to 60% of children[37] and cholesterol levels may increase by around 30%.[27] This can be treated by changes to the fat content of the diet, such as from saturated fats towards polyunsaturated fats, and, if persistent, by lowering the ketogenic ratio.[37] Supplements are necessary to counter the dietary deficiency of many micronutrients.[3]
Eggs are a healthy, nutrient-dense food that has been incorrectly maligned for years. Cholesterol in food doesn’t increase cholesterol in your blood, so eat eggs liberally – they’re packed with protein and lutein, and they fill you up for hours. Make a healthy omelet with some cheddar, crumbled breakfast sausage, and shredded spinach and you’re already looking at over 30g of protein, just for breakfast! Spinach is a great source of magnesium and potassium, too. Add some sea salt and you’ve got a big dose of electrolytes that are so vital to maintaining energy and staving off headaches.

Yvette, Oh no, sorry to hear about the chicken not being cooked! Was the chicken frozen to start with? If so, be sure to add 5 minutes to your Instant Pot cooking time (on manual high pressure). When we tested this, we literally just put everything into the IP (nestled down into the liquid, of course), and let it do its thing. The cream cheese softened, and when it was done cooking we removed the chicken to shred it, and the sauce stirred together nicely.
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.
Use fat as a lever.  We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.

A ketone is the by-product of fat being burned. It is basically an alternative source of energy (fuel) for your body. A more common source of body-fuel is the burning of glucose (sugar), but ketones are a preferred way of fueling the body. They are more efficient for the brain and the heart, and are better for your metabolism than running on glucose
'Cutting out carbs without advice can be dangerous, and can put you at risk of deficiencies in the long-term,' warns Dr Barclay. 'If you're looking to lose weight, burning fat may sound like the key to success, but in actual fact it comes with some risks, and may not be effective in the long term. The ketogenic diet is a short-term solution to a long-term health problem.'
I have been eating this way (very low carb, high fat, protein in between) for around 3 years now. I have found that for me I can MAINTAIN quite easily at an ideal weight and eating to satiety, but in order to actually LOSE weight, I have to at least have a very small calorie deficit. And though the change is gradual, it is sustainable and quite immediate (just little by little). The amount of that calorie deficit required in order to drop excess varies a lot from one individual to the next though, I think. I am particularly intolerant to hunger, and so I cannot overly emphasize how small of a deficit I will allow for. The nice thing about that though is that the hunger is far more pleasant in the absence of carbs.
"My suggestion is to start with changing your mindset first and foremost around three very important facts: this is not just another diet, you don’t have to live in Ketosis forever, and you will not be depriving yourself. Having said that, if you are used to eating highly-processed sugary food and refined carbohydrates you’ll need to ease into it," she explains.
Hi Gigi, Low carb and keto is about the balance of macronutrients eaten (fat, protein and carbs), not specifically meat or lack thereof. Most people on keto do eat meat, though some people do vegetarian keto. Fat is actually necessary for many body processes. There is no issue for the kidneys with a high fat diet, but if you eat too much protein that isn’t great for the kidneys. It’s a common misconception that keto is high protein (it isn’t). Keto is great for diabetics as it naturally helps stabilize insulin. All of this being said, please know I’m not a doctor and you should consult your doctor on any medical questions or before starting any diet. If you have more questions that aren’t medical questions, I recommend our low carb & keto support group here.
Note that the U.S. Department of Agriculture advises against cooking frozen chicken in a slow cooker or crock pot because slow cookers cook at a low temperature and may not heat chicken up to 165F, which is the minimum temperature to destroy any dangerous bacteria and ensure that chicken is fully cooked. So if you’re using a crock pot or slow cooker to make Crack Chicken, make sure to defrost it first!
What else happens when we break down muscle glycogen? We lose water weight! Our muscles store about 3 grams of water for every gram of glycogen, meaning we can lose quite a bit of weight right away when we tap into glycogen stores for fuel. That's why someone who loses weight in "just one week!" from a low-carb plan is likely losing water weight, not necessarily real weight that stays off over time.
The first modern study of fasting as a treatment for epilepsy was in France in 1911.[12] Twenty epilepsy patients of all ages were "detoxified" by consuming a low-calorie vegetarian diet, combined with periods of fasting and purging. Two benefited enormously, but most failed to maintain compliance with the imposed restrictions. The diet improved the patients' mental capabilities, in contrast to their medication, potassium bromide, which dulled the mind.[13]
It can be tricky calculating the precise kind of diet that leads to a long life. Part of the problem is that (thankfully) we don't live our lives in highly controlled laboratory conditions. Until that terrifying day arrives and we all become well-studied lab rats, we have to rely on long-term observational data, usually in the form of surveys, to know more about which diets are the best long-term plans.
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.
Hi Barb, That can definitely be it. Losing when you are close to goal can be more difficult. It could also be that your body’s healthy weight is a little higher than what you’d like – which doesn’t mean you can’t lose, but makes it more difficult. If just eating Keto foods isn’t working, double check the macros for your weight and see if the amount you’re eating needs to be adjusted. You’ll find more help and support in our support group here.
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.
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. Pure isolates, such as Signature 100% Whey Isolate, are extremely low in carbohydrate. 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.
Look at the glycemic index to choose the best foods for your ketogenic meal plan. There are websites that provide the glycemic index (GI) or glycemic load of different foods. The glycemic index tells you how your body's glucose and insulin system will respond to different foods. Foods that are lower on the index (or have a lower glycemic load) are foods that digest more slowly and will help you to feel full for a longer period of time.
As a result of those satiating fats required by the ketogenic diet, you may find you’re not craving snacks as much as you usually do. “I find people who follow the ketogenic diet, they’re just not as hungry, so their snack frequency comes down,” says Dina Griffin, RDN, with eNRG Performance in Littleton, Colorado. “There’s just so much fat in their diet, so they say, ‘I don’t want to eat again,’ or ‘I can’t, I’m just not hungry.’”
"I recommend designing the meal around the fat and protein sources, since the carbohydrates are very limited. For example, if someone is having tuna for lunch, they may consider adding mayo to it. I also think a common mistake made on the diet, is individuals focus on reducing carbohydrates, but they do not increase their fat adequately. This may make it difficult to go into ketosis, especially if they are consuming too much protein. Some adults can be on a stable ketogenic diet consuming 50 net carbs whereas some may need to restrict to 15 net carbs."
You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
