The first few months I was on the GAPS diet, I felt like I was on cloud-nine. I felt amazing, and was so happy to be free from the joint pain that had plagued me for nearly a year. After about 5 months on the diet, I started to notice some energy problems. Specifically, I started having spells of extreme lethargy and fatigue. Like, "I need to go lay on the floor for awhile" and "I can't keep my eyes open". After a bit of experimenting, I figured out that this problem was caused by eating too few carbohydrates.Is the GAPS Diet Low-Carb?
The GAPS diet is not necessarily a low-carb diet. Fruits, veggies, lentils, white beans, and honey are all allowed on the diet. But, I've tended to shy away from things like lentils and white beans while on GAPS because they can cause digestive upset for some of the other members of my family. I also tend to not each much fruit, as I don't really crave sweet things like I used to years ago. So for me, the GAPS diet can easily be very low carb.
Who Needs Carbs?
Other popular low-carb diets, such as Primal and Atkins, are quick to point out that people do not need carbs, since the body can manufacture them from other energy sources. However, it became clear to me that I do need plenty of carbs to have normal energy levels.
My daughter and husband, who are also on the GAPS diet, have not had the same energy complaints. It seems that perhaps being a woman, or specifically being a breastfeeding mother, can cause me to need more carbs. Or who knows, maybe it has to do with the foods my ancestors ate for thousands of years. Whatever the cause, it is clear that I can't follow a low-carb diet without having energy problems. I do know that there are plenty of other people, women specifically, who have complained of energy problems on GAPS.
Carbs and Adrenal Fatigue
Recently I've noticed that some of my old adrenal fatigue symptoms have been coming back: balding lower legs, vertical lines on the inside of my fingertips, and cold hands. As I've been researching the cause, I've learned that eating a low-carb diet can tax the adrenal glands! When the diet is low-carb, the adrenals have to keep sending out hormones to signal the liver to release glucose. I'm thinking that the return of my adrenal problems signals that I still haven't been eating enough carbs while on GAPS to properly nourish my body.
Steady Energy
To keep the energy levels more steady throughout the day, I'm eating more carbs. I include at least one of the following with each meal:
- Milk kefir or plain yogurt
- Winter squash, such as butternut or spaghetti: These seem to be fairly high in carbs compared to other veggies.
- Lentils
- White navy beans
To deal with any spells of extreme lethargy or fatigue, I find that eating one the the following helps.These give a quick energy boost and chase that lethargic feeling away.
- Fruit: I generally eat at least 3-4 pieces each day while on GAPS. Apples, pears, bananas, oranges, cherries, and blueberries all seem to work well for a quick energy boost.
- Macaroons: I keep a stash of frozen macaroons in the freezer. If I get that awful lethargic feeling, I'll go eat one right away.
- A small spoonful of honey

I just put up a post about this exact thing! I've been eating too low carb for a while on GAPS. Not on purpose. It just kind of happens when you try not to eat too many sweets and things like beans (they bother my nursing son too much). I'd be interested to hear your thoughts on my post. Thanks for your great info! Just what I needed.

This happened to me on GAPS too, but practically from the very start - I never felt good on GAPS. I have weak adrenals to begin with, so that's probably part of the reason. I was eating lots of yogurt and winter squash, but beans and too much fruit/honey didn't agree with me. I lasted 6 weeks as my energy levels sunk lower and lower, I lost too much weight, and I was feeling like I lost my zest for life. Basically I said screw it, I don't want to feel like this, and with my doctor's permission I added in potatoes, sweet potato and white rice. Turns out whole grains, beans and lentils cause my digestive issues, so adding in these "safe starches" didn't cause me any problems, and in fact improved my digestion!
ReplyDeleteThanks for sharing your experience, Debbie! I am actually transitioning off GAPS now and keep reading that white rice is easier on the digestion than brown. I've never even made white rice, but always used brown before GAPS, but I'm thinking that I should probably try white at first anyway.
ReplyDeleteI always used to cook brown rice too, according to the method in Nourishing Traditions. I also used to eat sprouted whole grain breads, thinking that was the healthiest option. The best thing the GAPS diet did for me was it made me realize that I cannot properly digest whole grains (or beans or lentils). I still stay away from gluten, but I'm happy with the newfound freedom that rice and potatoes gives me. Have you read about the Perfect Health Diet? They advocate these "safe starches", but only in moderation ie. don't go overboard on the carbs. White rice is easy...rinse it until water runs clear. Then add twice as much water as rice eg. 1/2 cup of rice, 1 cup water. Bring to a boil, then immediately turn down to very lowest setting, put lid on, and cook for 25 minutes. Good luck with your transition!
ReplyDeleteThis is such a good post. I have terrible chronic fatigue and a low carb diet was recommended for me -ironically FOR my adrenal fatigue. If anything, I felt worse energy-wise although I was finally able to lose weight. I am having such a hard time coming back to doing grain-free, etc. because that was so hard. It is hard when you have zero energy to make everything all the time!!
ReplyDeleteThanks Debbie and Natalie!
ReplyDeleteI'll look for the Perfect Health book at the library (I try not to buy too many books as I read so much that it would really dent my bank account).
And Natalie, yes it is so hard to make everything when you have no energy!! I find it helpful to keep a pot of broth going all the time (there is a post about that here: http://nourishedkitchen.com/perpetual-soup-the-easiest-bone-broth-youll-make/) So much easier than making lots of pots.
I feel like this is in the air right now. I'm planning on transitioning off GAPS in the near future, because the same thing happened to me, but about 8 months into my currently 10-month stint on GAPS. I felt great, started running, sleeping great, etc. And then it all fell apart. I read a great article about The Catecholamine Honeymoon regarding low carb diets (which GAPS can be sometimes, but isn't as bad as Paleo), and decided I had healed enough on GAPS to start transitioning out. http://180degreehealth.com/2010/06/the-catecholamine-honeymoon
ReplyDeleteSorry to keep bombarding you but this is a subject very close to me heart :) I just came across a link that kinda relates to this topic - in so much as it talks about diets like GAPS and SCD not being a "one size fits all", which was my experience exactly. Anyway...food for thought as you begin to transition.
ReplyDeletehttp://huntgatherlove.com/content/why-paleo-didnt-fix-my-ibs
Thanks for your post. I have gained weight (28 lbs in 6 months from my ideal weight) and have been very lethargic... tackling candida I have been having little to no fruits, pumpkin etc so I guess I now know why felt so terrible - I wish I'd found this out 1 yr ago! I've been giving the navy & lima beans a go.... not too sure they'll be ok! I had hoped to stay off grains for 2 yrs but may be I'll need to add in millet, quinoa & new potatoes just to give me some energy?
ReplyDeleteEven though I have been using coconut flour for a while, after looking at the nutrition table today of the brand I use, I discovered today that coconut flour has 9.1g of carbs per 14g of flour - so that would be a good thing to include as well.
ReplyDeletep.s. I love your raisin cinnamon loaf! - thanks for sharing that recipe! - my whole family loves it too! - although I did increase the coconut flour and almond meal amounts a little as the batter was quite runny.
I read your blog post and then saw this article just a little bit later: http://articles.mercola.com/sites/articles/archive/2012/01/07/dr-paul-jaminet-interview.aspx
ReplyDeleteThey are talking about the very same thing as you, i.e. loo low carb diet and how that can affect the body.
Thanks Everyone for your comments and links! I definitely agree that there is no one-size fits all approach to anything. Starches and grains definitely contributed to my joint problems so I had to avoid them for almost a year and a half on GAPS. So far I am experimenting with adding in potatoes and rice, and also eating much more. I have been really intrigued by Matt Stone's work, and his RRARF program specifically (which calls for eating way more food to flood the body with nutrients and resting more).
ReplyDeleteI know that we can live in ketosis, but increasingly my question is, should we? Is it really a default setting for the metabolism, or an emergency response? Ockham's razor says tubers are okay, I'd say.
ReplyDeleteNow if only I could eat cheese...
We just celebrated one year on GAPS. I've never really felt fatigue or lethargy, but then again I eat yogurt and coconut flour products every day. I did transition off of GAPS a little about two months ago ... and got slammed with a Candida infection (an issue I'd never had before). Boo. So now I'm back to a full GAPS diet. I'm also nursing our 7wk old son. Making sure that I eat plenty whenever I feel hungry. Sounds like if I continue the beans/lentils, coconut flour, yogurt, and fruit (like in my yogurt or as a dessert after dinner) I should be okay with energy?
ReplyDeleteHopefully your energy levels will be fine eating all of those, Bethany. It sounds like you naturally gravitate towards enough carbs on GAPS, whereas I could very easily not eat enough carbs. Just keep it in the back of your mind if you start to feel overly tired.
ReplyDeleteTHANK YOU for writing this Sarah!!
ReplyDeleteThis has been something that my husband and I have been talking about a lot lately. We've been struggling with energy levels and feel like we need more carbs.
My husband was talking about venturing off the GAPS diet, to include more carbs, because he was feeling he really needed it in his diet.
Honestly I've been afraid to venture off the diet because I don't feel our digestion is healed yet.
We've been wondering about adding sweet potatoes and parsnips. My husband has been wanting wild rice.
I know most importantly, I need to listen to my body. So, we'll see how our next diet adventures go.
Thanks for all you share.
I have done gaps for 26 months. In that first year there were times that carbs gave me more energy but then that stopped working. I am now doing the leptin reset and lower carb than ever before and also feeling better/more energy than I have had in a while. I never would have believed it till I experienced it. My adrenals are also thriving on this proticol and I am nearly off all adrenal support.
ReplyDeleteWow, Patty, thanks for sharing your experience. Can you give me any links to learn about leptin reset? Is there a specific protocol you are following?
ReplyDeleteI've been reading your blog for a while - thanks for all the great info!
ReplyDeleteRegrading fatigue on the GAPS diet I've had a similar pattern: adrenal fatigue before GAPS, initially better, then adrenal symptoms creeping back in. What worked for me was iodine. I've had slightly "off" thyroid hormones (slightly high TSH indicating hypothyroid but body temp and other symptoms more in line with hyperthyroid - not clinically either).
I did the iodine skin painting test which showed I was low so for a couple of months I drank sea-salt water with a pinch of kelp each morning and my energy steadily improved. I eventually felt I was getting too much because I started having insomnia so I backed off and sure enough the skin test showed I was at sufficiency. So that's an easy thing you might want to try. It's my understanding that adrenal fatigue can throw off thyroid and that iodine deficiency is very common.
Thanks Erin. I've actually been putting iodine on my skin the last couple days! I'm glad to hear of your experience.
DeleteSo great to read all these comments as I have been doing GAPS for about six weeks - I am relieved to hear that I might be one of those people who simply needs some carbs. I have been so exhausted, depressed and lethargic. I like the idea of the diet but have accepted that it is too extreme for me! WOnder if anyone is interested in the Blood Types? I'm
ReplyDeletetype A which is good with grains? How does this fit with GAPS?
I've never looked much into the blood type diets. One thing, from your comments: you might still be dealing with the initial die-off symptoms from the transition onto GAPS. Die-off can make you feel very tired, moody, lethargic, etc. This just means that the bad bacteria in your gut are dying off very rapidly, and as they die they release toxins that can cause those symptoms. GAPS is not necessarily low-carb; if I had to do it again, I would focus on eating lots of GAPS-legal carbs (lentils, white navy beans, winter squash, etc) right from the beginning.
DeleteI have just started the gaps intro diet...two plus weeks...I suffer from a hernia and have had acid reflux for many years...I take zantac to control the symptoms and had been stable...not needing to take it all the time just when I had an attack. I tried GAPS with my daughter and stopped the zantac and also librax which I took for occasional cramping...The result has been a nightmare for me. I don't have the pain but instead have a horrible burning from my throat to my stomach and also my chest and throat tighten up and feels terrible. I have it all the time and have been losing alot of sleep. At 68 and working fulltime I am exhausted and feel terrible. Any suggestions...I am wondering if I should do the full gaps diet and come back to the intro. Also wondering if I should wean myself off the medication rather than stop cold turkey, since I have been taking it for over 15 yars?
ReplyDeleteI must say first that I am not a medical professional. That being said, it seems like a prudent course of action to wean slowly off the medicine, and wait until you adjust to the GAPS diet before you do so. I would absolutely start with the Full GAPS diet and then come back to intro in a few months. That makes it much more manageable and also helps to make the die-off symptoms to a more manageable level.
DeleteI just wanted to add to this post that you need a lot of good fats if you are on low carbs. The other thing that I would suggest is scenar therapy for adrenal fatigue, and stay away from fruit and honey. Once i adapted the GAPs diet in this way it helped, and recently I have found a scenar therapist on the suggestion of a friend, and my life long battle with adrenal fatigue has gone. Its amazing to get through an entire day without that battle with fatigue. I used to sleep 10-12 hours anight and still have a 2 hour nap in the day. I still sleep up to 10 hours but not even a thought of a nap in the day time!
ReplyDeleteThanks for you comment, Stephanie! I've never heard of SCENAR therapy and will look into it!
DeleteHey Sarah,
ReplyDeleteHow have you been going adding potatoes and rice back into your diet?
I was on an anti-candida diet since march 2010 til october 2011 when I went overseas backpacking and started eating rice and potatoes quite often (plus probably vege oils and other bad stuff i had no control over...i was in asia). Since February I got really into a GAPS style of the candida diet. So basically the same diet except Ive added in dairy (Raw Kefir) which has been awesome, lots more bone broth, and probiotics.
Since february my acne has been great (reduced ALOT) and Im trying to heal and fade the rosacea i have on my face which Im certain is gut related.
Im tossing up whether to add back some rice and potatoes very slowly.
Look forward to hearing from you.
Paul
Hi Paul,
DeleteYou might be interested to read this post about adding back carbs and my experiences.
http://nourishedandnurtured.blogspot.com/2012/03/my-diet-update-and-results-from-diet.html
If I had to do it all again, I would still do GAPS but I would try to focus on making sure I eat enough carbs and never skipping meals for convenience. The GAPS diet can take a lot longer to heal than the few months you've been on it. Although symptoms subside relatively quickly, the gut still has to heal and this can take years. So it may be early for you to add back rice and potatoes (but to each his own).
Sarah I know we are both interested in Matt Stone because I have seen your posts there but I am very concerned for my son. He's 2 been on full gaps since Dec 2011 (now attempting intro to try to deal with the dairy allergy). Since starting GAPS his hair has thinned out a ton, his extremities colder, and he doesn't gain much weight. He is a thin guy. Im starting to become concerned since he can't eat dairy except ghee and the beans, nuts are hard on him so where are we getting all these carbs from? Additionally Ray Peat says nuts and FCLO has too much PUFA which suppresses thyroid. The heck - that is the GAPS diet! :)
ReplyDeleteHi Christina,
DeleteIt definitely sounds like your son is not thriving well on GAPS. I had the opposite experience with my daughter. Past the first month or so, we never ate tons of nuts on GAPS, so didn't consume many PUFA's. We focused more on lots of saturated fat through coconut oil, ghee, etc.
You could try to up the carbs by letting him eat more fruit, dried fruit, and you could try coconut flour baked goods (muffins, for instance). Also, winter squashes like butternut or pumpkin. Check out my recipes for muffins and clafoutis; those may work well for him since they can be dairy-free and nut-free (you can sub 3 Tb coconut flour for the nut flour in the clafoutis). If he can handle these things digestion-wise, maybe that would help.

Oh! Also, coconut milk ice cream could really help, and when he is able, you could switch to sour cream in the ice cream.

http://nourishedandnurtured.blogspot.com/2012/02/strawberry-ice-cream-gaps-legal-primal.html
Going without dairy was one of the hardest parts for my daughter, but we followed the dairy progression. Beginning with the test of putting homemade whey on the skin and looking for a reaction the next day; there was no reaction, so we started introducing whey a little at a time, working up to yogurt, kefir, hard cheeses, and finally raw milk. By the end of a few months, we were all able to tolerate raw milk with no problems.
From what I know now with Matt Stone's work, I would definitely try to eat more carbs form the beginning. After the first few months, I'd also let the kids have more of whatever GAPS-legal foods they wanted (like ice cream).
I hope this helps!!
