Is the calorie-free sweetener erythritol safe? The FDA did not evaluate long-term use, and new research suggests it may cause blood clots in people with high blood pressure and other risk factors.
Dr. Cate Shanahan’s book: The FatBurn Fix
Table of Contents
Why the new book? What’s the new info?
Deep Nutrition promises “This book describes the diet to end all diets.”
If you read Deep Nutrition, you know that Luke (my co-author) and I describe the ultimate, gold standard, global, you’d-see-it-everywhere-you-go Human Diet, the diet that sustained human health until the modern era and that, from the moment you adapt it, starts fixing nearly every chronic medical condition–including overweight.
Deep Nutrition focuses on gaining health more than on losing weight.
Deep Nutrition does not address the special problems that a person who struggles with weight must overcome.
Deep Nutrition was intended to help readers free themselves of medications and look and feel better about being overweight. It teaches that too much sugar and unhealthy PUFA-rich seed oils (PUFA=Polyunsaturated Fatty Acids) sets us up for serious chronic health problems. And it teaches the four pillars of the Human Diet, the essential food categories that support optimal health at every age.
Deep Nutrition also was inspired in part by my personal history as an athlete prone to injuries that I didn’t know came from a poor diet as a child, devoid of ‘meat on the bone’ (one of the Four Pillars of the Human Diet).
This article is continued below...(scroll down)
One chapter, called “Beyond Calories,” discusses how the standard advice to “eat less and exercise more” never worked for my patients, and how focusing instead on the information in our food helped revitalize people’s health. But for the most part, weight loss took a back seat because not all of my patients had weight trouble, and those who did experienced so many health improvements before they lost much weight.
The FatBurn Fix extends the “beyond calories” conversation. The book takes you along for a deep dive into the unexamined relationship between the ridiculous amount of PUFA now in our diets, and what that does to our metabolism. It explores how your metabolism affects your mood, your energy, and your risk of diseases. It talks about when calories matter and when they don’t. And most of all, it talks about how PUFA in our body fat interferes with our ability to burn body fat, thus turning your body fat from a source of energy on demand to an inflammation-prone burden.
The FatBurn Fix focuses on helping you burn your body fat.
Most people intuitively feel their weight has something to do with their medical problems. And that losing weight will help.
The assumption is that losing weight is the first goal; that weight loss alone helps people’s health. But that’s exactly backward.
It’s true that weight gain and diabetes and conditions like gout, arthritis, fatty liver and auto-immune diseases all run together. But we’ve got our cause and effect reversed. The reality is the process of developing diabetes starts before you gain weight. It starts the minute you begin to lose your natural ability to burn body fat. When you can’t burn your body fat, you gain weight. Inability to burn body fat makes you feel like eating more and exercising less. And that makes you gain even more weight.
It’s not you that wants to overeat. It’s not you that doesn’t have the energy to exercise. It’s your metabolism. If you’ve gained and been unable to lose or lost multiple times and regained, it’s your metabolism that’s the problem. Not YOU. Not your willpower.
The FatBurn Fix also shows you that even aside from weight gain, even if you gain very little weight or none at all, once you’ve lost your ability to burn body fat, your metabolism begins a downward spiral of worsening health.
Or course, you can easily fix your metabolism. It’s a no brainer.
That’s why I wrote the FatBurn Fix
Between 2010 and 2013 I traveled the USA to visit the top weight loss MDs in the country. What I saw was not good. Most people were only able to lose a portion of the weight they wanted to lose before dropping out of the program and eventually coming back even heavier. Every last person blamed themselves for their failures and although the doctors kindly told them that it’s not their fault, it didn’t really help the fact that they felt like failures. The philosophy of these practitioners was that obesity is a disease and, like asthma or gout or so many other diseases, you can have flare ups.
I became convinced those ‘flare ups’ occur because of something we’re overlooking.
I found my answer when I starting paying attention to how having all that PUFA in our body fat disrupts our ability to use it for fuel. If you can’t burn your body fat, you’re going to have a really hard time losing weight. In fact, you’re not ready to lose weight until you can burn your body fat between meals.
Essentially, your body fat becomes less and less visible to your cells.
So your brain thinks you’re starving and forces you to go eat
When your body can’t ‘see’ your body fat, you feel tired and hungry and have a series metabolic problems that set you up to develop not just morbid obesity but also serious metabolic diseases including heart attacks, cancer and degenerative neurologic diseases.
When you’re not good at burning body fat you can’t jump right into an exercise program and expect to start burning fat, nor can you cut your calories for long enough to lose much weight before you get overwhelming feelings of extreme hunger or fatigue–or other problems. Losing weight without a healthy metabolism is an ordeal filled with deprivation and fatigue. That’s why its best to focus on getting good at burning body fat first, then focus on cutting back your calories.
That probably sounds surprising.
But I don’t think it surprises anyone for long. After all, it’s intuitively obvious that you have to be able to burn body fat before you are ready to lose body fat. Most people assume they’ll be able to burn body fat by exercising. But exercise does not burn much fat when your metabolism is damaged.
What happens if you try to lose weight with exercising or low calorie diets when your body fat is still invisible to your cells?
If you can’t burn your body fat, calorie restriction and too much exercise can make you feel so bad that you give up. It may also worsen prediabetes.
How can exercise backfire this way?
What’s happening is that your body resists burning body fat even during exercise because your body fat is loaded with pro-inflammatory PUFAs from a lifetime of eating seed oils. To get energy your body must burn more sugar than your bloodstream is designed to handle. When your body needs so much sugar, you feel hypoglycemia (brain fog, shaky, etc.) after certain meals or after you’ve been very active. What happens to you next is your body starts converting muscle protein to sugar. In fact, this can even further damage your ability to burn your body fat and turn a prediabetic into a diabetic.
If you’re healthy enough that you’re really good at burning your body fat, you can exercise and the weight will melt off. You can intermittent fast. You can also jump right in to a low carb or keto diet. Losing weight is relatively quick and painless.
How can you burn ‘invisible’ body fat?
You can fix the problem of ‘invisible’ body fat very easily. You can eat foods that help your body ‘see’ the energy stored in your body fat. You’ll start by learning which foods sustain your energy between meals and that will very quickly revive your body’s ability to burn fat for fuel. The Fatburn Fix also teaches you what kinds of foods give you the feelings of satiety, so you can cut back on calories and never feel hungry. You’ll soon find that you actually get more energized the longer you go without eating.
The exact foods you need to eat to begin with are different from person to person. The tool I use to help identify what my patients need to eat is a quiz that give you a number between 0 and 100, something I call your FatBurn FACTOR. Knowing your FatBurn Factor is one of the tools you’ll get in the FatBurn Fix book that enable you to match your foods to the current state of your metabolic health.
In fact, you can take the FatBurn Factor quiz for free, right now, right here.
Whether you need to lose weight or just want to boost your energy and optimize your health, the FatBurn Fix will help. I hope you find it fun to read and useful.

Hi Dr. Cate, I have multiple lipomas all over the body. I have belly fat from many years and developed chest fat this pandemic.
Will the fatburn help the lipomas ?
Regards
Try adding more salt to your foods and be sure to get the supplemental vitamins and minerals I recommend. I hope it helps!
I’ve been in phase 1 since June 1st. I do not snack but still get hungry for dinner. My morning blood sugar is still about 100. I’m just wondering about how long would one expect for the body to start seeing the stored fat? How long do most people take to get to phase 2? Also, if the stored fat is made up of the PUFAS, will it be an efficient source of energy? Thanks!!
Hi Dr Cate
Have heard to much about the Fatburn Fix, but I’m based in South Africa and don’t seem to be able to buy a e-book or audio version of your book, which makes it very difficult for me to get hold of a copy. Any idea why these aren’t available in the Amazon US or UK shops to me? I haven’t had this issue previously?
Thanks and kind regards
Thea
I would attribute these findings to malnutrition, and that would be based on feeding slaves cheap high-carb, low-protein/nutrient value foods and royalty eating too much of the expensive honey and fruit. Possibly smoking as well or at least inhaling a lot of smoke. I don’t think we can diagnose insulin resistance in mummies! That said, if you try hard enough, lots of empty calorie foods and not enough protein/minerals/vitamins and so on, you can probably achieve IR without seed oils but with seed oils, it’s an inevitability and far moreso than is the case with sugar, in my view.
I’ve heard about this interview from others so you are not alone. The issue was malnutrition. The Egyptian slaves who ate a lot of cheap high carb wheat bread and the royalty who enjoyed too much expensive honey and fruit likely got too little of a variety of key nutrients. I doubt they had insulin resistance, though.
Hi Dr Cate!
I have been reading Fatburn Fix. I am astonished. I have suffered migraines for 53 years and even a Neurologist specializing in headaches could not figure out what you did. I definitely think I was prediabetic. I have had hypoglycemia symptoms for years. I am making good progress increasing healthy fats, cutting carbs, and cutting out snacks and unhealthy fats. I have felt well but all of a sudden I have a headache I can not get rid of and I feel kind of terrible. Is this the “Keto flu”? I am hoping it is a temporary signal that I am starting to burn some toxic fat reserves as I grew up on Canola oil and now see that the Hateful Eight are in EVERYTHING. Thank you in advance and THANK YOU for being the one who is changing my life <3
Wow! I could only wish to have your numbers! Find a holistic or integrated medicine physician. Your HDL is exceptional! As are your triglycerides!!!
Hi. The ratio is actually triglycerides-to-HDL. You divide the trig by the HDL. Under two is pretty good, and under 1 is very good. Over 2.5 is a significant indication of insulin resistance. (Page 115 in Fatburn Fix)
Hi Dr. Cate. I have a question. How long does it take for the body to heal and start burning body fat? I started phase 1 on June 1st. At that time, my HOMA-IR was 2.6 and my HDL/trigl. ratio was 1.97. I’ve been very strict on phase 1. It’s hard to know if I’m ready for phase 2. I certainly don’t get hungry for snacks but I do still feel the need for 3 meals (breakfast is only coffee with coconut oil and cream). Additionally, I don’t feel very energetic (could be the covid blues). I’m just curious about how long to expect to be on phase 1. Thanks in advance!
Ah, yes the carbs are best consumed with the evening meal in all phases. And yes most people do better with fewer calories, or calorie restriction, with breakfast than they do with calorie restriction at dinner.
Thank you, I’m on the 2nd reading of your Fatburn Fix, so I understand the need for quality source foods. I’m ready to move to Phase 2. I just wondered if there was an optimal way to divide up the macros over just two meals a day. For example, would it still be best to eat most of the carbs with the evening meal? And for Phase 2, still restrict the calories at breakfast and eat the greater meal for dinner?
Please don’t focus on macros, focus on food source quality and freshness. That said, to get you started, most calories should be coming from whole food fats and good oils, like 50-80%. We need 60-120 gm protein daily, from whole foods not veggie burgers loaded with “protein” powders and isolates/hydrolysates, and 0-40% from slow digesting carbs. Lots more info in the book, of course!
Natural flavor is often some pretty great stuff (essential oils from lemon rind, for example, gently extracted) as long as there’s no MSG in it, which there is probably not in sweet dominant beverages.
Will be doing a FB live with Michael Yo later today on this. Athletes need to be able to burn body fat and the modern diet blocks that. It’s not about the macros as much as the types of fatty acids. Much related info in the book, of course.
Possibly a uninformed question… what would the macros look like on this way of eating for performance/aesthetics? Would it be somewhat traditional to the sports nutrition norms or vastly different? I’m actually certified in sports nutrition but I have pcos and have been struggling greatly producing the results I want for my own body composition. Kelly Starrett turned me on to your stuff and I really want to dig in and apply it.
Hi Dr Cate, we have been reading your books and following your eating guidelines since we discovered you on the Bill Maher episode. My husband Roy is a fellow Cornellion.
Quick question if we may; we notice on our flavored sparkling water beverages the addition of “natural flavor”. Is this something to avoid?
Thanks for your guidance!

My husband and I eat only two meals a day. How would you recommend we divide the calories, grams of fats, carbs and proteins? We don’t snack.
In the FATBURN fix I recommend watching the triglyceride to HDL ratio and 2 or better is a good goal. It can take months to years to improve depending on age/metabolic health. But it will imrpove.
Great interview on Bill Maher’s show. I immediately bought Deep Nutrition and The Fat Burn Fix and have read them both. I have been working with a Functional Health doctor since March to cure my IBS. I have actually been eating like you want us too since the end of March, Prior to starting with this doctor I had done keto for 3 months. I did notice during that time that my constant hunger and craving went away. That is the case right now so I have started your keto phase 2. My question is in The Fat Burn Fix you state that your
LDL to HDL ratio should be 2 or better. Does that mean 2+ or 2-? I just had my medicare “wellness physical”, what a joke. The doctor didn’t want to hear anything about nutrition and told me to eat low fat, high carb to get my lipid numbers down. Cholesterol 218, triglycerides 114, HDL 40, LDL 155 If the ratio should be 2+ I am good. Also, blood sugar is still 102. How long will it take to get that down? I have lost 22 pounds since January, but I am still 35 pounds overweight.
Lactose is the milk sugar, which is fermeneted away in hard cheeses and removed from ghee. If your issue with dairy is lactose, you can enjoy the many dairy products that are naturally free of lactose.

Lower the intensity of your workouts. More like base load work outs in zone 3. Stay out of zone 5 for a least 4-10 weeks. Whatever you normally do in your baseload phase of pre season type program.
Thanks sooooo much for your reply. I have stripped back everything, trying to keep carbs around 20/day, and now I have diarrhea. I have never experienced this on a low carb, but I’ve never been this age and this heavy. lol. I’ve added a few more carbs today and will see how it goes. And I’m looking at trying Keto recipes instead of such a basic palette. Wish you offered a user friendly food/nutrient journal. Have also added the minerals and no more leg cramps at night! yay.
Thank you for teaching us about how the body actually works. We transformed our diet about four years ago after reading your books. We feel great! (family of four). i just read “fat burn,” though weight loss is not an issue here, to get more clarity. I really appreciate all of it, especially the teaching on cholesterol, and that you shared your cholesterol numbers in the discussion. Since changing my diet i have “red flag” numbers and my doctor is puzzled and worried (age48, female). When i asked him to follow up with tests you recommend to calm him down, he said “ok fine, but i don’t know how to read those tests.” So i am figuring it out myself best I can and he doesn’t get it. This book clarifies all the questions. It has been stressful to look and feel great, and then have GP and Endocrinologist say “something is wrong here. You have to get these numbers down!” We need more MDs like you that get it to help us. (curious? Fall2019 labs: triglycerides 58, HDL 107, LDLcalc 207). My best friend heard these numbers and begged me to eat oatmeal and take a statin. I continue to declined both. I am always seeking information and learning. Your work has had a huge impact, offering a way to get through the chatter. THANK YOU.
The problem is here in the US most ‘farmers’ are not farmers, they’re CAFO managers so our cows pigs and chicken eat mostly soy and corn and have horrible lives. If you can’t afford $35 a pound for grass fed steak, for example, and don’t want to participate in the horror, plant based makes sense, in this one generation. Is it good for the next? Not ideal. And that’s another big problem most folks don’t want to talk honestly about.
If your hunger is controlled (gone) you can try keto or phase 2, in phase 2 you start pulling back on calories by skipping a meal or making a meal much smaller. Let us know how it goes!
Great interviews and love this philosophy! As with all eating lifestyles, it’s easy to get confused with SO much information out there. I’ve been feeling better eating a mostly plant-based diet, which seems to go against so a lot of theory in your book… (like eating organs, which I actually love then read they were awful for you?). Do you see any advantage in eating primarily plant based? What are your thoughts on (non-hormonal) dairy? All fishes/shellfish okay as long as wild-caught? Thanks!!!
I purchased and am enjoying your Fatburn Fix book after meeting tin Bill Maer. Thank you!! I use ground flaxseed in water as a morning drink to avoid constipation. Is this a safe practice?
I understand your premise and appreciate your response. That’s a lot of fat per day! I’ve been doing this for a few weeks now at around the lowest gram amounts and drinking 48 oz a of water a day and no weight loss. And I know this is a lifetime of eating the wrong foods. I also understand the need for regaining energy first, but I feel like I’d have more energy if I could get some of this weight off quicker. Again, thanks for the quick response.
For Phase 1 Baby Steps (not Keto) carbs should range 50-100 grams (200-400calories) per day, protein 60-90 grams (240-360 calories) per day, and the rest of your daily calories come from fat. We’re not focusing on weight loss, but rather adequate energy, so you can use any calculator to figure out your maintenance calories. Say for example your maintenance calorie intake is 2600, then subtract 400 for carb 360 for protein, that leaves around 1800 or so for fat, or about 200gm.
Does that help?
Even though weight loss is not the focus, you’ll probably end up losing a little weight anyway due to hopefully feeling like being a tiny bit more active.

Have read the FatBurn Fix after seeing you on Bill Maher. What is the balance of % of carbs/proteins/fat? I read start with 50 g of fats, but what’s the balance and beginning caloric intake? I’ve got a lot of weight to lose. Thanks.
I have recently read your book, The Fatburn Fix after seeing you on Bill Maher. I have a lot of weight to lose and have been obese all my life. My question is what is the % of proteins, carbs, fats, that you should start with in Phase I? I know carbs start at 50 grams, but I’m a little confused about the balance. Thanks. And caloric amounts to start?
Please visit this page https://drcate.com/list-of-…
The FATBURN FIX plan provides information on how to build meals that prevent hunger.
If that’s a new problem you didn’t experience before then I’d add more of the slow digesting carbs into the meal(s) proceeding those tough workouts. Also, you could consider making those high intensity workouts shorter duration.
Quick question – I’ve been adhering to the Fat burn Fix Stage 1 for two weeks and it is going great! But, when I do high intensity aerobic exercise (cycling) I really crash afterward and feel near-hypoglycemic feelings that I don’t like. My question is, should I just work through these discomforts, or should I modify in some other way? Thanks for your book – it’s awesome.
Well, hello to a friendly troll! LOL
Yes, it does.
No those are not normal reactions. You may not be getting enough healthy fats, which is a common cause of problems especially among those of us who grew up during the low fat craze. Your symptoms should resolve quickly by adding healthy fats if that was the issue.
Do make sure you are getting the recommended vitamin and minerals. Carpal tunnel is more common when your nerves lack nutrients and/or the ability to fight inflammation.
Good Bill Maher piece thank you. I have removed vegetable fats, sugar, alcohol and refined carbs. The first two days I felt FANTASTIC, the next two I’ve had muscle fatigue and morning shakiness. Are these normal reactions? Also, in ‘Fatburn’ there’s a question about carpal tunnel in one of the symptom surveys. I wonder why – as I had a surgery, but now am told the problem has returned after only 1 1/2 years!
Introduced to you on Bill Maher. What you are saying resonates with me and I will make some diet changes. My docs for years now want me on statins, but my gut tells me to avoid them. I am 66 years old. You say to avoid butter substitutes, does that include Smart Balance?
KInd bars are made with palm kernal oil. How bad is this?
Great job on Bill Maher, Dr. Cate! Enjoyed it.
Great interview on Bill Maher! Thanks for the info. Have been putting 2+2 together.. metabolism is key re Covid & also NAD. I’ve been reading amazing info on natural NAD activator. Without NAD you are nada basically, & it declines with age.
Thank you. I saw you on Bill Maher’s show this past Friday. I ordered your latest book. Great information. Thanks again.
In the FatBurn Fix, briefly. Also I discuss starting on page 305 of Deep Nutrition. More about oils here: https://drcate.com/list-of-…
Do you talk about peanut oil in your book?
It would be helpful to know your FatBurn Factor and what you ate prior to feeling hungry, as well as how much time it takes to get to that point.
I’m on Adderrall XR for ADHD. Are there any strategies for fixing metabolism when on a stimulant medication? I’ve been following the recommendations in “The Fatburn Fix” and am having difficult gauging when I’m hungry before getting to the point where I can’t think anymore. I’ve looked through your site/Q&As.
