This book is great. I’ve been on the diet for about two months and have already lost ten pounds, and I feel a lot healthier.

I have been waiting for this book all my life. I have tried every diet with no success. I knew there had to be a diet that was nourishing but also did not create constant cravings. I have been on this diet for just a few days, but already feel much better and have less cravings. I will be recommending this book to all my family and friends.

Both of my grandmothers lived to be in their hundreds. They both cooked their own meals and ate lots of potatoes and onions. Neither had ever been hospitalized. Both died from complications from broken hips. I have been low carb for a couple of years but after the first 40 #s I am just stuck. Can’t lose more weight and still need to release about 50 more to be at a health weight. After I got the book I started immediately with adding potatoes and rice and lost 2 # this week. I liked that I had the bare bones of the book with diet info at the very beginning. Took me a week to finish the book. Now I feel like I too will be able to be a spry healthy person in my later years. I am a 57 year old female and looking forward to life with a healthy and strong body. Thanks for such an informative book and for the hope it gives us all.

It’s been said before…but it really is the sanest book on health. No exaggeration or gimmicky ideas, just very sound and practical information that completely makes sense. I am rereading for the fourth or fifth time and still having dozens of epiphanies. This is one book I am buying for as many loved ones as I can convince to accept it. I started on zero-carb, lean-meat-and-veg Paleo, and became painfully thin and developed some health problems, and now I have gained weight, but in a good way–I get some compliments on looking toned or, once, to my surprise and delight, like a runner (though I exercise little). And I have fixed several other problems. I am just dying to give this to everyone

In short, this book has changed my life. Since adopting the PHD shortly before Thanksgiving, I have lost 25 pounds. I have not “dieted” at all. I just simply removed the foods the book suggested and ate more of the foods recommended. I have also practiced the intermittent fasting suggested in the book.

I feel unbelievably better. I have 10 times the energy and the pain in my joints is gone. Consequently, I have been exercising more regularly. The pounds are just melting off. I have not been at my current weight since I was in High School over 25 years ago. I can’t wait to go to my physical and see my blood work. In addition, it is now fun to sit by the pool in my bathing suit and wear my entire new wardrobe.

I have been a type 1 diabetic for almost 30 yrs-low carb was life changing for me for a good number of yrs. I was 30 grams or below each day without cheating (ever) for a few yrs with really great results. I truly thought I found the magic fix! after I developed an autoimmune thyroid problem things went south and no matter what I felt bad-very low carb can cause issues with converting t4 into t3….I explored adding the PHD safe starches back in with good results. for me, carb balance is a must. if I am too low carb for a wk or so I can tell. As soon as I up the starches I get some relief.

So here’s a story for you. Friend just gave birth. Baby and mom are great. Mom is 36. First two babies were at age 21 and 24. Then despite best efforts, no babies came–and mom was so, so sad. At 32, she decided the age span was too large and she didn’t want to keep trying. They started using birth control.

A year ago March, mom was diagnosed with Crohn’s and she could only tolerate those awful elemental diets. Slowly, she added joint stock (pressure cooked) with feet, joints. Then little bits of egg yolk and liver in the stock. Then meat. Then bits of blended veggies. Eventually, she was eating essentially a Sarah Atshan version of PHD (lots of soup!)

Around the same time, they stopped using birth control thinking that it was pointless anyway because, after all, they’d tried for 9 years to no avail.

Then, after 5 or so months on PHD/AIP/traditional foods, at age 36, she was pregnant! **After 9 years of trying**

Uneventful pregnancy.… Amazing n=1 for treating infertility that was, in this case, likely both male- and female-factor.

I also switched from VLC. I’m about 5 weeks in, and I already consider this a success.

When I switched to PHD, I had just gained over 20 lbs on low carb Paleo, with thyroid symptoms (terrible!!). I continued to gain after starting thyroid meds. Then after switching meds, and starting the PHD, I gained another 8 lbs. However, in spite of the gaining, I feel DRAMATICALLY better. More clear headed, more energy. I’ve included resistant starch and my gut is doing so much better!!!

I believe I may have just lost a couple lbs. I’m trying to not get on the scale, and focus on healing and taking care of myself. Trust me, would LOVE to lose these 28 lbs!! However, I want to be healthy, and this is getting me there, I believe it.

I like the saying “you don’t lose weight to get healthy, you get healthy to lose weight”.

Hi everyone, thanks for adding me. My story, if anyone is interested: I had been on the paleo diet for over 4 years, getting more and more low carb until I went ketogenic for over 1 year, eating just fat and meat, zero or close to zero carbs and I was getting more and more more fatigued. I started experiencing increased stiffness in my body, especially my neck. I seemed to be always in a sort of spasm around my shoulders. I was feeling constantly nauseous and I had recurring sharp pain in my stomach area. A visit to the doctor could not explain what it was. I started experiencing something I never had before: a burning sensation in my mouth, an insatiable thirst. I could drink as much water as I wanted, it was to no avail. It was literally as if my mouth was on fire. I also started having the sensation of head pressure and head pulling that felt like there were strings attached to my brain and somebody was pulling down on them. For the first time in my life I started developing insomnia problems. I would sleep only 5 or 6 hours, sometimes wake up in the middle of the night. Then there was phlegm in my throat. Years ago it used to be extreme and it improved dramatically since i stopped eating grains but then came back on the low carb and ketogenic diet. I kept on spitting out clear phlegm. Most curious of all: I gained weight! That was truly baffling to me. I was literally not eating any carbs. It was just meat and fat. Organic 100% grass-fed burgers with 20% fat content and slabs of organic grass-fed butter on it – and I was gaining weight. Or I would drench everything in coconut oil. When I mean no carbs, I mean not only no potatoes, rice etc, but also no starchy veggies like carrots, beets, winter squash, not even salads. I would eat a salad maybe once every 3 or 4 months. so then somehow by accident I came across mark sisson’s article on marksdailyapple.com about candida and him mentioning Paul’s theory that candida feeds more readily on ketones than on carbs and I decided to put it to the test. Given that sweet potatoes were part of the paleo diet I thought that that allowed me to safely test the claim without me having to break my paleo/keto diet strain and still remain at least a “pure paleo dieter”.

By the time I had returned from the grocery stores on the day of the test I hadn’t eaten for a good 3 hours and with a now sober eye I noticed that the head pressure had increased and the stiffness in my neck and body was escalating as well. I cooked and ate the sweet potatoes I had just bought and the relief I felt was nearly instant. Within 20 or 30 minutes the head pressure which had been unrelenting for good 1 year, just dissolved. Fatigue improved markedly as well as the body and joint stiffness.

The painful insatiable thirst that not even a gallon of water a day was able to quench? The sweet potatoes took care of that. The constant nausea? I wasn’t even done eating before I noticed an immediate relief.

I had taken a theory, tested it and verified it. Within 3 or 4 days I had lost the extra weight I had accumulated around my waste on the ketogenic diet. I stopped spitting out clear phlegm. My energy was better and the body stiffness stayed better as well. The heart palpitations which hadn’t allowed me to sleep, stopped. I haven’t experienced them since.

I was sold.

That was around 9 months ago. Since then I kept proving Paul’s theory correct every day, several times a day. I’ve learned to tune into my body and know now when my body goes into ketosis and when it’s time to eat some carbs to not allow things to escalate. And it works every time.

Paul, feel free to add this to your testimonials on your website if you want.

Anyways, thank you so much for helping me out of my ketogenic diet delusion.

Thanks, Paul!

Just a few days on the diet and I can’t believe how much better I am sleeping and how little hunger I have.

My menstruation cramps have completely diminished and that has never happened before. I almost get it always the first day menses and it usually keeps me doubled over in pain for at least 10-15 minutes and for the rest of the day it would just be a gnawing pain at my side. So the fact that I barely have fatigue (except from my finals) and that I feel no painful cramps anymore has completely blown my mind. I have always had pain and it always incapacitated me for the week. I am so fascinated by this fact.

I have Bipolar type II. It’s been a month and a half [since I started PHD] and I am not looking back. Eating along the lines of the PHD is definitely having a positive effect on my moods – significantly reduced diurnal mood variation, less depressed mood and much better sleep.

I would like to thank you from the bottom of my heart for writing one of the best books ever written.  Your research is so thorough and your conclusions are so enlightening.  Your work has greatly improved my life and my health and for that I will be forever grateful.

When I was 16 years old, I was diagnosed with scoliosis which caused me pain and hardship.  Every doctor I went to said basically the same thing, “It’s not so much the degree of curvature that is plaguing you, it’s the inflammation.”  In 30 years of seeking treatment, not one doctor ever asked me what I was eating.  After beginning the Perfect Health Diet in order to lose some weight, I ended up curing my back pain in the process.  The inflammation was aggravated by a diet high in carbohydrate and low in fat.  In fact, when I was 16, I had been on a Weight Watchers program that allotted me one tablespoon of olive oil a day and that’s when I had the first flare up.  In hind sight, each time I would attempt to lose weight, my back would freeze up and I then I couldn’t exercise, so I would gain more weight.

Now, at 46 years old, I have reached the goal weight that was set for me when I was 16–and the process is so enjoyable!  I now go for weeks without even thinking about my back pain!  It’s a miracle!

Hi Paul. Quick feedback. My concern was prediabetes and eating a pound of potato/ day. Well for 1 year now I have consumed half a pound a day and been fully complient with PHD. One year ago A1C was 6.6, this week A1C is 6.1. Thank you for all you do.

I have been wanting to let you know that I tried your eczema recommendations for my pre school daughter and within only a couple of days the eczema dramatically reduced and it was completely gone within a week. I also start taking choline, along with the standard supplements you recommend and I actually feel a lot better.

First I just want to say thank you PHD. I truly believe the book you co-wrote is one of the best books ever written and should really be taught in schools. I follow your diet and it has changed my life for the better.

I wanted to send you a thank you note for your work on the blog and the book. Like a lot of other people, I have been looking for a more healthy diet for ages, and found the cornucopia of diet information available on the internet to be highly confusing, if not downright misleading. I found your blog after reading recommendations on Chris Kresser and Mark Sisson’s blog, read through the a lot of it, and ordered a copy of your book.

This was in February of this year. Since then, I have lost about 25lbs and have run a 10K with my wife. My wife, who was fit to begin with, jumped on board early, and not only has she reached her goal weight, but her skin looks so clear that people have commented on it. I got additional copies of the book for my parents, sister and extended family, and everybody who has read the book has lost weight after following the diet. My father has lost lost 10lbs, which has been amazing, since his doctor has been recommending that he lose weight for years! I did not expect to convince people this easily, but after all, nothing works as well as results!

Dorothy wrote:

I have been following your PHD closely for 6 months including 16 hour fast daily, eating only twice and taking a course of probiotics. I have a fairly benign form of MS but 18 months ago got a bad outbreak of eczema which I have never had before, combined with a deterioration in my MS. This was arrested after a few months of PHD incl all supplements as well as the additional Lysine and Arginine you advised for MS….

But just to say again, I have had a wonderful improvement to my general health and MS and I attribute this to the daily fasting, eating your recommendations and the hour- long strength/ weight training twice a week. The combo is very very powerful medicine :))

Reading your book and practicing the diet has been very beneficial to me. I was diagnosed with Irritable Bowel Syndrome and have been suffering pain, bloating, et cetera for 30 years. My symptoms are now 80% reduced. I am trying to perfect my diet using your guidelines to alleviate the other 20%.

My husband and I had purchased your book a few months ago, and I had been reading your blog for awhile. We have fully implemented the PHD way of eating and it has been about three months now. It has made a big difference for us both, in improved health and weight. I have had no more heart palpitations, and my leg cramps have subsided. (and i lost 4 lbs) …

My husband and I have both had significant improvement on your Perfect Health Diet and were low carb before so enjoyed the addition of the safe starches. Thank you for such a great, great book!!

I would like to thank Paul and his wife from the bottom of my heart. I was on Gaps for 2 months to deal with digestive disorders and pain. I noticed good results on GAPS but after 2 months looked like I was wasting away. I had very low energy; dry mouth; low libido, yellow, gelatinous semen; flat mood; gum infection (lowered immunity). It seemed to me that carbs and starch were the ultimate “bad guys.” After reading Paul’s work, I realized they are actually necessary. Within 2 days all the above symptoms reversed, and I am feeling better than ever. This is a detail that the current low carb fad has not addressed. I was really worried for my health, and can’t even imagine going years on very low carb. For someone like me with a fast metabolism, I would probably end up dead. Thank you again – you guys are a great light in the dark.

Heartfelt thanks for creating such an erudite comprehensive and lifeimproving work. A friend of mine who is suffering from type 2 diabetes and non alcoholic fatty liver disease adopted PHD some 15 months ago and for the first time [she has tried scores of diets] in her life has not felt hungry! She has taken all the recommended supplements[other than coconut oil which causes indigestion]and after 9 months and 2 daily fasts a week she is now consistently loosing weight.

I had ringworm and seborrheic dermatitis and lots of amalgam fillings. I still have the fillings, but fungal problems went away on PHD. The ringworm went away immediately. The dermatitis took six months. For a while, it would come and go depending on stress or circadian rhythms. If I stayed up late watching TV too many nights, it would flare up. Hasn’t flared up for at least 8 months now.

I came to the PHD after a very mixed experience with the GAPS diet, which I tried after a recommendation from my sister in law. I have had chronic health problems since I was 18, and have been diagnosed with mild CFS/ME, IBS among other things. For the last 10 years I have had chronic inflammatory back pain, which remarkably is much better after I started changing my diet. Having taken NSAIDs for a decade I found after some time on the GAPS program that my pain recovered enough that I could manage without them. However after about a month and a half on the program I began to feel really ill. My GAPS practitioner encouraged me to stick it out, but I needed to work and was feeling so ill that driving was difficult, let alone doing my job, which requires me to think fairly hard at least some of the time! I decided to try a medically trained GAPS practitioner, and she basically had me eat loads of butternut squash, a safe starch according to the PHD! This helped a lot, but in the process I had come across the PHD and bought the book. As a scientist your book was a breath of fresh air, I had resigned myself to accepting what I thought was essentially a trial an error approach to diet based on intuition (GAPS/Western A Price style), or the medical establishment approach (when I consulted my doctor during my GAPS issues he told me I was a hypochondriac as I was not overweight so why should I be on a diet?!). Now I follow the PHD and my back pain is 90% resolved, although I still have some health issues.

My 5 year old son, diagnosed with autism, does very well with a no fructose version of the PHD. But there have been a couple foods that have been incredibly good for him, and I just had to share our experience. The first is raw egg yolks. I know from your book that having 3 yolks a day is good for many people, but I find that when my son has 2 yolks, 3 times a day (each serving about 4 to 6 hours apart) his language and eye contact is so much better. The positive effects seem to wear off in a few hours, so we find that multiple doses throughout the day works well. Sadly, cooked egg yolks have had no good results.

The second food that has been really good for him is resistant starch. We give him 1 TB of raw potato starch with his probiotic, 3 times a day, and he is so much more social and more affectionate than ever before! I was nervous to try it because my son does not digest most carbs or fiber well, and I was worried about the potential increase in SCFA (since some very compelling research by Dr Derrick MacFabe implicates propionic acid in autistic symptoms). But so far, we have seen no negatives and only wonderful results.

For my son, his autistic symptoms will wax and wane depending on what he eats. And trust me, I know how crazy this may sound, but we actually have days now where it seems like his autism has nearly vanished. I have no doubt that his gut plays an utterly profound role in his mental health.

My wife and I have both been trying the PHD diet this spring. We both feel better, have more energy and certain acute symptoms (e.g. IBS) are gone. But our experiences with weight loss are very different–I have lost 25 pounds since February with limited exercise, she has lost nothing.

  1. Best health book ever! I’ve given away so many copies! I intend to keep giving the book to family, friends, and anyone else who comes across my path who is interested!

  2. My wife and I have decided to more frivolous gifts, from now on everyone gets a copy of “Perfect Health Diet”, no matter what the occasion!

    What better gift than the gift of health?

  3. Hi Paul.

    Perfect Health Diet has become the best health book for me.

    I read it a few times in order to understand the details better and implement them in my daily life. I think your holistic approach is what makes it the best book in the health & diet industry (I lost 14 pounds in 2 months without having any difficulties).

    I’m sure you will continuously improve and update your recommendations in the light of new information that you learn in the months/years ahead and this website is a great source for this kind of content.

    I visit the site regularly to see if you post a new article or not. Please write more often so that we can learn more from you:)

    Thanks a million for creating PHD.

  4. In reading about potatoes and resistant starch, I see various recommendations.
    Eat potatoes raw (Dr. Wm Davis), Boil them and put them in the fridge (Stephan Guyenet), etc. Any thoughts?

  5. When eating cooled potatoes are you reheating them or eating cold for the RS3?
