I hear this all the time. “I can’t eat keto because. . . ”
What is your excuse?
I am amazed at how tightly people cling to these excuses. They are just that excuses. In the 16 years I’ve been training people how to use these diets to treat disease, I have yet to find one that is not just an excuse that covers up the real reason . . .
I’ve had many of my patients and followers on social media ask about my continued use of the hashtag #JustKeepEsterifying. Well, here is the answer. Check out the short 4 minute video below to get the answer:
I get asked this question all the time. And, my answer is that 85% of the people that walk through the doors of my clinic will not be fully successful in weight loss, reversal of diabetes, normalization of blood pressure and reversal of heart disease and/or vascular disease without it.
I am frequently asked, “Is Keto for everyone?” Does everyone need to follow a ketogenic lifestyle? The answer is “No.” 15% of the population will be able to maintain great health with calorie restriction and exercise. However, the principles that provide a successful ketogenic lifestyle are easily understood and incorporated by anyone looking for improved health, energy and weight control.
Principle #1 – Insulin is the Master Hormone
Insulin is the master hormone when it comes to weight loss and the diseases of civilization. Whether you are insulin resistant or not, insulin is essential for life and proper function of the cells of the body, but too much insulin production in response to sugars, starches or complex carbohydrates causes disease.
How do you know if you are insulin resistant (producing too much insulin)?
Skin tags are pathognomonic (a characteristic indicative of the presence of disease) for insulin resistance. If you have skin tags, you may want to focus your diet on increased carbohydrate restriction.
You may not need to completely remove carbohydrate from your diet, however, recognizing that not all carbohydrates are created equal and avoiding those with higher carbohydrate content will help many improve weight and halt the progression of disease. I have many patients that with just partial carbohydrate restriction they are able to lose 20-30 lbs, improve their cholesterol profiles and improve their blood pressure.
There are sixteen different diseases that respond very effectively to carbohydrate restriction. You can read about them and how the ketogenic lifestyle effectively reverses them in The Keto Cure.
Principle #2 – Saturated Fat & Cholesterol Aren’t the Demons We’ve Made Them Out to Be
Saturated Fat and cholesterol aren’t the demons we’ve made them out to be. Another way to put it is: “Don’t blame the butter for what the bread did.”
Since 1984, nutrition experts treat fat and cholesterol containing foods like the witches of Salem. Experts castigate their use as if they were the “Avada Kedavra“ curse of the fantasy world.
As an example, eggs, specifically the egg yolk (the part of the egg containing all the cholesterol and saturated fat), have been demonized by just about every health magazine I’ve ever read. (To this day, the chef at every breakfast bar I’ve ever visited asks if I want an ‘egg white only’ omelet.) Interestingly, there is actually no scientific data association between whole egg consumption and heart disease. The science simply does not exist. Seriously, check for yourself.
I personally eat 6-8 eggs a day and my cholesterol is perfect. Back 1000 years ago, only the aristocrats at the chickens. All laborers and serfs ate the eggs . . . who would be dumb enough to eat your food source? (Don’t answer that.)
For example, the MR-FIT study, the largest cholesterol study ever completed, is incessantly quoted as the study that demonstrates reduction in cholesterol leads to reduction in cardiovascular disease, but this trial was actually a failure and did not demonstrate improved risk by lowering cholesterol. In fact, the Director of the study, Dr. William Castelli stated, “. . . the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower people’s serum cholesterol…”
Researchers found that people who ate the most cholesterol, including the most saturated fat, weighed the least. They were also the most physically active. In fact, the British Medical Journal published a 2015 study demonstrating that saturated fat is NOT linked to vascular disease, diabetes or increased mortality (de Souza RJ et al., BMJ 2015,351:h3978).
In my clinic, the basis of appetite suppression is eating adequate protein that includes saturated fat and cholesterol. This is the most powerful tool in my clinical approach to the treatment of weight loss. I can use foods like red meat, bacon, butter and coconut oil without concern or worry of heart disease as long as you are keeping your carbohydrate intake less than 20 grams per day.
Baseline insulin levels allow for peace of mind about heart disease risk. Heart disease risk goes down when insulin levels are maintained at normal baseline levels. Increasing saturated fat, while at the same time lowering carbohydrate intake has been demonstrated to shift the cholesterol to a more heart protective form (Griffin BA et al., Clin Sci [Lond], 1999 Sep).
Principle #3 – Nutritional Ketosis Has Anti-Inflammatory & Age Slowing Effects On the Body
Ketones in the blood at a nutritional level (0.5-4 mmol/L) have tremendous anti-inflammatory and age slowing effects on the body. Even having them present intermittently has dramatic improvement on overall inflammatory changes and disease in the body.
Ketones are the usable fuel of the body when the liver breaks down fat for energy. They suppress the NLRP3 inflammasome in every cell in the body. This is important because it allows for more rapid recovery from exercise. It also dramatically decreases pain and fatigue that comes from diseases like arthritis, rheumatoid arthritis, multiple sclerosis and auto-immune disease (Y.H. Youm, et al., Nature Medicine, vol. 21, no. 3, pp. 263–269, 2015.)
If full blown ketosis isn’t for you, partially restrict starch and carbohydrates for a mild to moderate benefit. Even small amounts of ketones in the blood are helpful. This provides increased recovery time, and improved inflammation control.
So, even if you don’t follow a strict ketogenic lifestyle, the principles above are powerful. These three principles make this dietary approach universally effective for weight loss. They are also very powerful for disease management. Even partial application of carbohydrate restriction can benefit just about everyone.

So, you’ve started a ketogenic lifestyle and you’re a few months in . . . but, is it really working? How do you know? You should be seeing your waist shrink. But, is all that butter really good for my cholesterol? What about my blood tests?
I commonly get these questions over the last 12-13 years of using a low-carbohydrate or ketogenic lifestyle approach in the treatment of obesity, diabetes, cholesterol and high blood pressure. We can determine the effectiveness of the diet on your metabolism with some simple blood testing.
What Lab Tests Do You Need?
Watch the video below to find out what tests are right for you:
Why don’t you check all the other inflammatory markers like HS-CRP, Lp(a), etc? Because, I know that these test will be elevated if insulin is > 5 mmol/L and if sdLDL particle is > 500 nmol/L.

Over fifty years of data have demonstrated that creating energy deficit through the reduction in caloric intake is effective in reducing weight. . . However, it is only for the short term (1, 2). The biggest challenge physicians face in the treatment of obesity is that calorie restriction fails when it comes to long-term weight loss.
Isn’t Fasting Effective in Long-Term Weight Loss?
With the craze and popularity of intermittent fasting, some have claimed that intermittent fasting is more effective in weight reduction. Recent results demonstrate that this may also be incorrect. In the short term evaluation of caloric restriction and intermittent fasting, reduction in 15-20 lbs of weight is effectively seen and the highly publicized Biggest Loser’s losing ~ 120 lbs. Intermittent fasting and alternate day fasting have been shown to be more effective in lowering insulin levels and other inflammatory markers in the short term.
There is, however, controversy over maintaining weight loss beyond 12 months in the calorie restriction, intermittent and alternate day fasting groups. Forty different studies in a recent literature review, thirty-one of those studies looking at forms of intermittent fasting, demonstrate that the majority of people regain the weight within the first 12 months of attempting to maintain weight loss(3, 5). This is, also, what I have seen for over 18 years of medical practice.
Is Calorie Restriction the Only Way to Lose Fat?
Numerous “experts” claim that the only way to reduce fat is “caloric deficit.” Variations through the use of intermittent, long-term or alternate day fasts can be found all over the internet. In regards to calorie restriction, these “experts” with nothing more than a personal experience and a blog to back their claims preach this louder than the “televangelists” preach religion. Based on the faith that many place in this dogma, it could be a religion. What causes belief in this dogma is that weight and fat loss actually does occur with caloric restriction to a point. The average person will lose 20-25 lbs, however, within 12 months of achieving this goal, most people regain all the weight. (No one ever mentions the almost universal problem with long-term weight loss, especially those “experts.”)
Prolonged calorie restricted fasts, intermittent fasts, and alternate day fasts are often grouped together into the fasting approach, causing significant confusion among those that I speak to and counsel in my office. There is great data that alternate day fasts do not have the reduction in resting energy expenditure that prolonged fasting, intermittent fasting and calorie restriction cause. However, none of these approaches appears to solve the problem of weight re-gain after long-term (12-24 months into maintenance) weight loss (3). And, a recent study of 100 men participating in alternate day fasting showed that there was a 38% dropout rate, implying that without close supervision and direction, maintenance of this lifestyle is not feasible for over 1/3rd of those attempting it.
Long-Term Weight Loss Failure Brings Tears
Failure on calorie restricted diets, low fat diets, and intermittent fasting diets with weight regain at twelve to twenty-four months is the most common reason people end up in my office in tears. They’ve fasted, starved themselves, calorie restricted, tried every form of exercise, and still regained the weight. Trainers, coaches and “experts” have belittled them for “cheating” or just not keeping to the diet. Yet, we know that calorie restriction and intermittent fasting cause a rebound in leptin, amilyn, peptid YY, cholecystikinin, insulin, ghrelin, gastric inhibitory peptide and pancreatic poly peptide by twelve months causing ineffective long-term weight loss (6). The dramatic rise in these hormones stimulates tremendous hunger, especially from ghrelin and leptin.
Although less problematic in alternate day fasting, these calorie restricted approaches also cause dramatic slowing of the metabolism at the twelve month mark. In many cases, the metabolic rate never actually returns to baseline, creating even more difficulty in losing further weight or even maintaining weight (6).
Is Gastric Bypass or Gastric Sleeve the Solution?
Gastric bypass and the gastric sleeve procedures have been touted as the solution to this problem, as they decrease ghrelin, however, 5-10 years later, these patients are also back in my office. They find that 5-10 years after these procedures the weight returns, cholesterol and blood pressure rise, and diabetes returns. These hormones kick into high gear, stimulating hunger in the face of a slowed metabolism, that to date, has been the driver for weight regain in the majority of people. People find it nearly impossible to overcome the hunger. You may have experienced this, I know I have.
It’s the Hormones, Baby!
So, what is the answer? It’s the hormones. (WARNING – You’ll hear that when your wife is pregnant, too, gentlemen). We are hormonal beings, both in weight gain, and in pregnancy. Trying to preach calorie control to a hormonal being is like showing up at the brothel to baptize the staff. You might get them into the water, but you’re probably not getting them returning weekly to church or pay a tithe.
So, how do you manipulate the hormones in a way to control the rebounding hunger and suppression of metabolism? This is where we put a bit of twist on the knowledge we’ve gained from alternate day fasting. Recent research shows that “mild” energy deficit in a pulsatile manner, that has the ability to mimicking the body’s normal bio-rhythm’s is dramatically effective in reducing weight and maintaining normal hormonal function without cause of rebound metabolic slowing (4).
Pulsed Mild Energy Restriction
What does this mean in layman’s terms? It means that if we provide a diet that maintains satiety hormones while providing a period of baseline total energy expenditure needs and a period of mildly reduce caloric intake in a pulsed or cyclic manner, greater weight loss occurs and there is no rebound of weight 1-2 years later.
The main reason I’ve not jumped on the intermittent fasting band wagon is the shift in leptin, amylin, ghrelin and GLP-1 signaling that regularly occurs at the 6-12 month mark. The rebound of these hormones causes weight re-gain and is what prevents successful long-term weight loss. A number of people come to my office and tell me they couldn’t follow a ketogenic diet, so they’re doing intermittent fasting and it works . . . for a while. Then, they end up in my office having hit a plateau or fallen off the wagon and regained all the weight. They are completely confused and don’t understand what happned. Most of them are convinced it’s their thyroid or cortisol and they’ve seen every naturopath and functional medicine doctor in town.
What people really need is a simple approach to long-term weight loss without having to spend the night in the physiology lab every two weeks sleeping under a ventilated hood system.
The Ketogenic Lifestyle is a Pulsed Energy Lifestyle
Third, providing adequate fat is the simple way to maintain leptin, ghrelin, amylin, GLP-1 (among the others) and long-term weight loss. Can you eat too much fat? Of course you can. But, because each of us have differing levels of stress and activity each day, this fat intake becomes the lever for hunger control.
Fourth, the use of exogenous ketones ensures easily accessible ketone (short chain fatty acids) to modulate adipose (white fat) signaling of the liver without large caloric intake through the portal vein by first pass of liver metabolism. The ketones also help stabilize the gut bacteria. The combination of hormone balance between the liver and fat cells and improvement of gut bacteria suppresses key hunger hormones and aids glucose regulation between the fatty tissues and the liver. Ketones, both endogenous and exogenous, suppress production of TNF-alpha, IL-6, resistin, and stabilize production of adiponectin and leptin from the adipose cells (7, 8, 9).
In my office, once we calculate the basic protein needs daily, we start with a 1:1 ratio of protein to fat. Then, the fat is adjusted up or down based on hunger. Remember, hunger occurs, because your body produces hormones. The addition of fat to a diet that is not stimulating large amounts of insulin resets the hormone patterns back to normal without causing weight gain.
Give Obese People Fat Ad Libitum?
“Sure, Dr. Nally, but what about those people who don’t know if they are hungry, bored, stressed or just have a bacon fixation? You can’t just give them all the fat they want?!”
Why not? Implying that people aren’t smart enough to know when they are full is a bit of a fascist philosophy, don’t you think?
Do people over eat? Sure they do. But, I’ve found that when you give people an antidote to hunger (using fat intake in the presence of stabilized insulin levels) over a few months, people begin to recognize true hunger from other forms of cravings. This is especially true when they keep a diet journal. This gives people the ability to begin listening to their own bodies, responding accordingly and governing their stress, eating, exercise and activity. Keeping a diet journal is key to long-term weight loss. And, isn’t helping people use their own agency to improve their health really what we’re trying to do?
Interestingly, doing this over the years seems to line up with the findings of this year’s MATADOR study in the International Journal of Obesity. They found that mild intermittent energy restriction of about 30-33% for two weeks, then interrupting this with two weeks of a diet that was energy balanced for needs improved both short and long-term weight loss efficiency (4). In looking at my, and my patient’s diet journals, this energy restriction of about 1/3 of needed calories cyclically seems to happens naturally with a ketogenic lifestyle, without even counting calories. (Calories are a swear-word in my office).

You may have seen this puzzle previously . . . it’s made its rounds in corporate training circles. But the underlying principle remains true. The solution requires you to expand your thinking or to “think outside the box.”
Whenever you find yourself on the side of the majority, it is time to pause and reflect. (Mark Twain)
Why should we limit ourselves to thinking outside the box. Can’t we just get rid of the box?
True discovery consists in seeing what everyone has seen . . . then, thinking what no one has thought.
The answer can be found when those four lines are used beyond the box our mind creates:
What good has the box done us? People were burned at the stake because they refused to believe the Earth was not the center of the universe. People were beheaded because they had a sneaking suspicion that the world was not flat.
Why is it so very hard to accept that our weight gain and diabetes are driven by a hormonal signal, and not by gluttony or caloric intake of fat? The definition of insanity is doing the same thing repetitively and expecting a different outcome. How long have you been restricting calories and fat with only minimal or no improvement in your weight, blood sugar, cholesterol or general feeling of health?
The main problem with the current thought model, or dogma, on the obesity’s cause is that it does not account for metabolic syndrome. Metabolic syndrome is insulin resistance. It is an over production of insulin in the presence of ANY form of carbohydrate (sugar or starch).
In the practice of medicine over the last 15 years, I noticed that a very interesting pattern emerged. There was always a spike in fasting and postprandial insulin levels 5-10 years prior to the first abnormal fasting and postprandial blood sugars. These patients were exercising regularly and eating a diet low in fat. But they saw continued weight gain and progressed down the path of metabolic syndrome. 10-15 years later, they fall into the classification of type II diabetes. What I now lovingly refer to as stage IV insulin resistance.
The only thing that seems to halt this progressive process with any degree of success is carbohydrate restriction. Fasting insulin levels return to normal, weight falls off, and the diseases of civilizations seem to disappear as insidiously as they arose.
So you tell me, is the world flat? Is the Earth the center of the universe?

I found these charts to be very helpful when trying to calculate your fat intake with a meal. Fish can be challenging in calculating fat content. After reading these charts, I’m craving some sashimi’ed mackerel and salmon.
I’ve personally been following and prescribing ketogenic diets to my patients since 2005. When I started on my ketogenic journey, it was called a “Low Carbohydrate Diet.” Over the last 5-10 years, we’ve learned a thing or two about how the body processes carbohydrate, protein and fat. Specifically, it’s not just the restriction of the carbohydrates that leads to metabolic health, but appropriate protein intake and significant emphasis on the level and type of fat intake as well. The majority of people who cut out carbohydrates will initially see successful weight loss, but to maintain that weight loss and see significant metabolic changes that reverse the diseases of civilization, an understanding of protein and fat needs are essential.
It’s Not Necessarily a High Protein Diet
Most people, when they hear you’re following a “Low-Carb” diet . . . respond with, “Oh, you are on that high protein, Adkins’ thing, . . . right?!”
Well, not really. A true ketogenic diet is NOT a “high protein diet.” However, you must be ingesting enough protein to maintain muscle, hair growth and energy levels. Most people, having been brainwashed in grade school and middle school about the horrors of fat in the diet, assume that if you’re not eating carbohydrates, then you must be eating extra protein to stay satiated. (No one would ever intentionally increase the fat in their diet, right?!!) However, remember that protein and fat usually come together in the sources that the Good Lord put them in.
That’s the impression that most people in my office get when I mention the words “Low-Carb” or “Adkins.” And, before I have a chance to explain that I’m not recommending that you race home to eat three large turkey legs and a pound of turkey bacon, the vegetarians gather their things to leave and the former home economics teachers begin to get chest pain at the mental picture in their heads.
How Are Ketones Made?
A ketogenic diet is one which allows your body to use ketones as it’s primary fuel source. Ketones are produced from the breakdown of triglyceride and free fatty acids. Ketones are essentially produced by two distinctly different events:
1) Starvation caused by prolonged periods without food (which is essentially what happens to type I diabetics when they have no insulin at all in their systems)
2) When fat is ingested as the primary fuel, and very low levels of insulin are concurrently produced, primarily when the diet has minimal to no carbohydrate present (allowing the body to activate its free fatty acid reserves found within in the adipose cells).
The body is an amazing machine. It was designed to take any of the three main macro-nutrients (carbohydrate, protein or fat) as fuel and function quite well. It’s like a futuristic car that can run on unleaded gasoline, oil, or diesel fuel. It is able to recognize which fuel is present and run quite well off of any of the three. The amazing thing about the body is that we mix up all three fuel types and just pour them into the tank. Impressively, the body can separate them out and run very well in the short term on any combination of mixes. We don’t have cars or trucks that do that today . . . maybe in the future . . .?
We have Two Fuel Systems
I like to equate carbohydrates to unleaded fuel. These are clean burning, easy to access and cheap. However, the body requires the production of insulin to use this “unleaded” type of fuel. When carbohydrates are identified to be present in the liver and pancreas, insulin is released so that the rest of the cells throughout the body can “open the tank” and let the carbohydrate into the cell to be used as fuel. The challenge is that carbohydrates don’t store very well in the form they are supplied in, so, as a protective mechanism against starvation and famine, if excess carbohydrate is found in the system, it is converted into triglyceride. Insulin is required for this. Interestingly, when your insulin levels rise, the signal to the body is that “unleaded fuel” is in the system, so it stores any fats and excess carbohydrates in the form of free fatty acid and triglyceride. Carbohydrate stimulate an insulin response and cause fat storage. It is the same reason we give corn to cattle — to plump them up before taking them to market.
Fat then is the “diesel fuel” of macro-nutrients. It burns well, can be stored very easily, and provides over twice the energy to the body when measured in the form of k-cal per gram. Fat is used preferentially when there is limited or no insulin floating around the blood stream and is quickly and efficiency stored when other forms of fuel are available. (Insulin being the key hormone signaling that other fuel is around.)
Nutritional Ketosis is Using Fat as Your Optimum Fuel
So what is this “ketosis thing?” It is a method of dietary change (a lifestyle) that intentionally focuses the body’s metabolism to use fat (in the form of triglyceride & free fatty acid) as its primary fuel. Leading to weight loss, dramatically improved blood sugars, significantly improved cholesterol and triglyceride levels, and notably improved inflammatory markers.
“But don’t you end up eating a lot more protein on your weight loss program?” I frequently get asked.
Honestly, No.
Protein and fat are both very filling, and most people find that limiting the carbohydrates actually causes less hunger and diminishes the rebound carbohydrate cravings often stimulated by the two or three slices of bread, pasta or that potato often occurring 2-3 hours later. Interestingly, most people don’t eat that much more and the protein levels remain fairly constant. Because fat and protein come together in meats, eggs, fish, etc., satiation occurs with just minor increases in dietary intake real animal food. I don’t recommend increase the fat alone. I recommend increasing the amount of real animal protein until you are full. This is even more satiating and many people find themselves eating only twice a day when they are hungry.
Excessive protein in those who are morbidly obese with severe overproduction of insulin can experience a spike the insulin levels further with large amounts of protein. Protein can be equated to the oil you put in your car. Protein is a building block used for muscle, connective tissue and some essential metabolic functions. When too much protein, in this group is ingested, it spikes the insulin. (See my article on Why Your Chicken Salad is Making you Fat)
Most people have problems when they start supplementing with protein shakes. These often contain sweeteners that raise insulin and consequently halts your weight loss – or even causing weight gain.
