Ketogenic Diet Plan
The goal of a low carb, ketogenic diet plan is to achieve a metabolic state called ketosis. Ketosis is simply a normal metabolic process in which the body cells burn fragments of fats called ketones instead of glucose for fuel.
Ketosis is a beneficial process and helps the body survive during times when no food is available. It has also been shown to improve disease conditions such as epilepsy, autism, Alzheimer's, cancer and others.
This page will answer some questions you may have about a ketogenic diet plan including:

Note of Caution
You should check with your physician if you have any concerns about starting a ketogenic diet plan with pre-existing health conditions, especially if those conditions involve kidney or heart problems.
Although ketosis, and ketogenic diets in general, are beneficial for most people, there is some anecdotal and research based evidence that suggests that ketosis will cause a transient increase in the body's levels of adrenaline and cortisol for a small subgroup of people.
These higher levels of stimulant hormones can cause thyroid issues, heart irregularities and elevated blood pressure for some, while others just feel more alert.
If you find you are one of the people in this subset, adding enough carbohydrate back into your diet to come out of ketosis should resolve the issues, and still allow for the health benefits and weight loss, if desired. However, you should consult your doctor about starting a ketogenic diet if you have any concerns.
However, be aware that most classically trained doctors don't understand the effect of foods on the body, much less ketogenic diets, so you may get push back, and a terrifying "danger of ketosis" sermon.
Just remember the doctor is confusing nutritional ketosis with a more dangerous condition called ketoacidosis. These are two different conditions; click on the link to read why.

Now back to our regularly scheduled program..
The Basic Concepts
There are many low carbohydrate, ketogenic diet plans from which to choose. (The Atkins diet is just the most famous). They all involve following a higher fat, moderate protein, low carb food plan.
The main difference between a regular low carb diet plan and a ketogenic diet plan is the amount of carbohydrate and protein allowed on a daily basis:
- A ketogenic diet plan requires tracking the carb amounts in the foods eaten and keeping carbohydrate intake between 20-50 grams per day. The daily protein requirement will be moderate, and depends on height, gender and how much exercise is done. The balance of calories will be from fats. These ratios ensure that most people go into ketosis and stay there, which is the main objective of the ketogenic diet.
- The nutrient intake on a ketogenic diet typically works out to about 70-75% of calories from fat, 20-25% from protein, and 5-10% from carbohydrate on a daily basis. Since a ketogenic diet reduces hunger, most find they don't really need to get involved in calorie counting, unless one feels more comfortable tracking them.
The key to understanding a ketogenic diet plan is to remember that one is swapping out the carbs in the diet with a higher fat and a moderate protein intake.
Why high fat and moderate protein? Fats have no effect on blood sugar and insulin levels. Protein does affect both blood sugar and insulin, if large quantities are consumed. If you overeat protein, about 56% of any excess protein will be converted to glucose (sugar) in the body, and that extra glucose hanging around will increase insulin, and put the brakes on the body's ability to release and burn fatty acids (go into ketosis).
In addition, eating a diet that is heavy on lean protein (without enough fat) can make one sick with a condition know as "rabbit starvation". It can also wreck the metabolism in other ways.
How to Start A Ketogenic Diet Plan
Before you do anything else, get a book that explains the science behind ketogenic diets and read the whole thing. Make sure to understand everything that will happen when carbohydrate intake drops. Ketogenic diets are very powerful, metabolically speaking. This is especially important if any kind of medication for blood pressure, cholesterol or triglycerides is being taken. These books are highly recommended:
Once you have a good understanding and are ready to start, these tips will help you succeed:
- Get a carb counter guide (see sidebar) to help learn and remember the carb counts of the foods being eaten. Counting carbs is a critical part of the program, and it's important to understand how to do this correctly.
- Go on a carbohydrate sweep. Inspect kitchen cupboards and refrigerator, and remove all of the high carb foods. This includes any whole grain "complex carbs".
- Restock the kitchen, so that the foods on this low carb food list are available. This will help keep you on the path, grasshopper, and out of the cookies. Here's a low carb grocery list to help with food shopping.
- A ketogenic diet plan is not a "special diet" that requires special foods. There is no need to buy any "low carb" packaged foods. Ketogenic foods are essentially just real, whole foods which are close to their natural state. In other words, they are not highly processed. The only exception to this is the category of artificial sweeteners. These are highly processed. However, I think these are important to include in a low carb diet plan, because a small amount of fake sweetener has less of a negative effect on health than the standard amounts of sugar in sweetened foods. Some people may prefer more natural sugar alcohol sweeteners, but studies have shown these are "antiketogenic" and can derail the process of ketosis for some. They effect each person differently, so you'll have to test to see if they effect your health or weight loss goals.
- Be prepared to spend more time in the kitchen. This is an important point. A ketogenic diet menu involves cooking and eating real foods. If you don't know how to cook, this would be a good time to learn about cooking in general and specifically low carb cooking.
- Think about your meals, and how you will plan them. This will help in buying the right foods at the grocery store, and give a framework to follow when meal time arrives. If you know you're supposed to have salmon and broccoli for dinner tonight, it makes it a lot easier to avoid choosing the old high carb foods you used to eat.
- Replace old habits with new ones. If you're used to hitting the coffee place for a bagel, start making coffee at home, and have it with the eggs instead.
- Stay hydrated. As carb intake is lowered, the kidneys will start dumping the excess water the body has been holding due to a high carb intake. Make sure to drink enough water to replace what gets lost. The old 6-8 glasses is a good rule, I guess, although just drinking to thirst will probably do the trick. If you find yourself getting headaches and muscle cramps, you need more water, and more minerals such as salt, magnesium and potassium, because the water loss also takes minerals with it. (See my low carb diet side effects page for more info).
- Avoid the foods on this list of high carb foods. These are the foods that drive up your blood sugar and insulin levels. In addition, cereal grains like wheat are toxic for more people than is widely known. I think that most people with diet related health issues have an untreated gluten intolerance.
- Consider taking these natural supplements. I recommend them for the specific issues I discuss on my low carb diet side effects page.
- You may also want to buy some Ketostix Reagent Strips so that you can check to see if you are in ketosis for the first few weeks. However, after the first 3-4 weeks on the plan, the goal is to become "keto-adapted". Once adapted, the body should be burning the ketones for fuel. The stick shouldn't register as deep purple if you are using the ketones as a fuel source. And recently, a blood ketones meter has become available to track ketosis at home. This is a much more accurate way to track your individual ketone levels. See the sidebar on my ketosis page for more information.
- Find some way to track daily food intake and carb counts. Keep a spreadsheet, use one of the online food intake trackers, or simply write it down in a journal. Not only will journaling help you stay on track carb count wise, you'll want to have a record of the foods you are eating, how you felt and the changes you make so that if you go off track, you can look back and see what worked for you. This is a good place to track ketone levels as well. I've created a free printable food diary for you to use. The Atkins website also has some nice tools for tracking your progress on a ketogenic diet plan. And this database is an excellent resource for food information.
- Think about any social situations that will be encountered, and devise ways to handle those times when temptations to eat the "old" way will be high. You don't want to be blind sided when someone at the office brings in a box of your favorite chocolates and puts them right under your nose. Likewise, a beer with your friends usually turns into a date with potato skins and nachos. Think salad and steak instead.
- Even if you are starting a ketogenic diet plan for weight loss purposes, don't focus on your weight. Don't weigh yourself every day. Your weight can vary between 2-4 pounds each day because of changes in water intake and absorption. You won't be able to track any fat loss accurately on a daily basis, and the fluctuations will make you crazy if you focus on them. Instead, weigh yourself once a week, or keep track of your body measurements to track your progress. Better yet, focus on the health benefits and the long term health changes that come with eating a low carb diet. Knowing that you are greatly improving your health is a powerful reason to stay with a ketogenic diet plan, even if you don't lose any weight. I discuss in more depth the health benefits of a ketogenic diet in this article published in the July/August issue of the Well Being Journal.I recommend getting a health check up and a blood panel test done just before starting the diet, so that you can track the effect of the change in your eating habits on your cholesterol, blood pressure, and other health markers. Four to eight weeks later, you can get another blood test done and see if there are improvements.
- Learn how to stop sugar cravings. There are supplements and techniques that can help you overcome those nagging thoughts of dessert and get your blood sugar under control. As time passes, you'll find that ketosis is a powerful appetite suppressant, so it should get easier to abstain the longer you eat ketogenically.
Fallacies and Fears: Is a Ketogenic Diet Plan Dangerous?
The "dangers of low carb diets" are really just myths told by people who have a limited understanding of how low carb diets work.
The main criticisms include fears about fat intake and the process of ketosis.
- Fears about fat: Most people have trouble on a ketogenic diet plan because they are scared to increase the amount of fat they eat, especially saturated fat. The message that fat is bad has been pounded into the collective American consciousness for the last 30 years. It's hard to unlearn the message that fat makes you fat, and saturated fat especially is very bad for you. I understand that message has been repeated over and over, but it is a lie.
Here's the reality: A high carb diet drives up blood sugar and insulin levels. All that sugar and insulin are inflammatory. The standard American diet offers lots of foods that are high sugar AND high in saturated fat, and in studies, these two factors were lumped together. So although saturated fat is healthy, it got the blame for the inflammation that causes heart disease because it was studied in combination with a high carb diet. A ketogenic diet plan which is high in saturated fat and very low in carbohydrate will REDUCE inflammation. (Reference here.)
- 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. (See my Healthy Eating Politics website for more information on the how the lie that "cholesterol and saturated fat cause heart disease" got started and gets repeated.
- Some people don't do well in ketosis. As I mentioned above, you should check with your physician if you have any concerns about starting a ketogenic diet plan with pre-existing health conditions, especially if those conditions involve kidney or heart problems.As I said above, although ketosis, and ketogenic diets in general, are beneficial for most people, there is some anecdotal and research based evidence that suggest that deep ketosis will cause a transient increase in the body's levels of adrenaline and cortisol for a small subgroup of people. These higher levels of stimulant hormones can cause thyroid issues, heart irregularities and elevated blood pressure for some, while others just feel more alert. It's for this reason that I don't recommend going much lower than 15-20 carbs per day. The ketogenic is a very low carb diet, but it is not a zero carb diet.If you find you are one of the people who doesn't feel well at very low carb levels, adding enough carbohydrate back into your diet to come out of ketosis should resolve the issues, and may still allow for the health benefits for sure, and weight loss, for some.
General Side Effects
Switching to a ketogenic diet plan is not easy at first. Here's a list of all of the common side effects that will happen the first week or so of starting a ketogenic diet. If you know about them, you can take steps to minimize them, and save yourself some carb withdrawal misery.
That withdrawal period and side effects are associated with the time it takes for your body to refit itself to burn mostly fat instead of sugar. New enzymes have to be created.
Dr. Mike Eades has a great analogy for this process in this blog post. He writes:
"When you’ve been on the standard American high-carb diet, you’re loaded with enzymes ready to convert those carbs to energy. You’ve got some enzymes laying in the weeds waiting to deal with the fat, but mainly dealing with it by storing it, not necessarily burning it. All the pathways to deal with carbs and their resultant blood glucose are well-oiled and operating smoothly.
Then you start a low-carb diet. Suddenly, you’ve idled most of the enzyme force you have built to process the carbs in your diet while at the same time you don’t have a ready supply of the enzymes in the quantities needed to deal with your new diet.
It would be like a Ford automobile factory changing in one day into a plant that made iPads. All the autoworkers would show up and be clueless as how to make an iPad. It would take a while – not to mention a lot of chaos – to get rid of the autoworkers and replace them with iPad workers. In a way, that’s kind of what’s happening during the low-carb adaptation period.
Over the first few days to few weeks of low-carb adaptation, your body is laying off the carbohydrate worker enzymes and building new fat worker enzymes. Once the workforce in your body is changed out, you start functioning properly on your new low-carb, higher-fat diet. The carbs you used to burn for energy are now replaced to a great extent by ketones..."
In addition, during the first week or so, your blood sugar will drop, and you may experience insulin overload and a reactive hypoglycemia episode once you burn through all of your stored glycogen (carb energy stored in your muscles and liver).
For those of you that have been living on a high carb diet for a long time, the effects may be even more pronounced, as your blood sugar and insulin levels are probably chronically high.
Benefits and Dangers
As mentioned above, the "dangers of low carb diets" are false beliefs and unsubstantiated fears communicated by people who have a limited understanding of how low carb diets work, or by people with financial or professional reasons to maintain support for the low fat, high carb message.
For instance, since the privately owned Academy of Nutrition and Dietetics (formerly the American Dietetic Association) receives great sums of money from processed food manufacturers, they can't just suddenly start saying that a high fat, low grain diet is healthiest - they would lose all their funding from companies like Kraft Foods, Hershey's and Coca-Cola.
The more likely result of a ketogenic diet plan, once you've adapted to it, is that you will feel much better and be much healthier. One of the long list of health benefits of a ketogenic diet is that it lowers your fasting blood sugar and insulin levels, helps reverse insulin resistant conditions, cools inflammation and in turn, leads to better overall health.
If you have any lingering concerns, please remember that the latest scientific studies (visit the Nutrition and Metabolism Society) have shown that following a ketogenic diet plan is not detrimental to human health, if it is eaten while also minimizing carbohydrate intake.
It's only when you combine lots of fat and lots of carbohydrates in your diet that you get into trouble. The sugar from the carbohydrates drives up your insulin levels, and those high insulin levels cause any fat you eat to be stored immediately. This causes the weight gain associated with insulin resistance and starts the health problems that should be associated with a high carb diet, not a ketogenic diet plan.
