Keto breastfeeding and milk supply


Thank you FrankoBear for clarifying this with me. I must have missed that section on the podcast so I’ll listen again and check out your other recommendation. This all makes sense to me now; well on a basic science level. I do have a blood sugar monitor at home that I used during pregnancy to check my levels daily. Would that be a help or do you require more scientific equipment? I can also monitor Symptom. So far I’m feeling good and my milk supply is fine. Last time by day 3 my supply was deteriorating and I felt drained. It’s really quite shocking that the “expert” advised her plan and said it would be plentiful when in fact it was low calorie low protein and low carb all at once. Given I lost 3.5kg in the first week is telling how taxing it was. If my supply dips again and I easily know by his behaviour, I’ll know to add in a serving of carbs and probably oats Nd has they are the most effective for me along with flaxseeds.
I really do appreciate everyone’s comments. there is a wealth of knowledge and experience on this board above and beyond a so called nutritionist and expert. I have already gained so much knowledge on this forum.


Thanks NuchRimfire for your input. My knowledge falls a little short to clearly understand what your saying but I am hearing you say, and correct me if I’m wrong, because bfeeding pulls glucose, say 30g, a low carb/keto diet only supplying 20-30g falls short of this. So through glyconeogenesis? Then protein is used to create the glucose required…so don’t short change yourself with protein, use my requirements as a minimum?
I did just read an article from Dr Jamie Seemans ig account stating that the process of glucogeonesis? Is actually low (using protein to make glucose?)…if that were correct one would be better to add in the 30g if carbs then rather than extra protein?


I think your milk production and how you feel is most relevant. The blood glucose metre is good as an adjunct. When you feel really good and relaxed check your blood glucose a few times to get an idea of your normal. Then, if you feel off colour, you can test and see if there is a difference. If it is low blood glucose (without ketones) you apply your oatmeal fix (or any wholefood carbohydrate). These are just my thoughts based on what you have been sharing. For the complex stuff consider a lactation consultant. I had never heard of these before. But apparently they exist in the USA according to Neisha Berry (Dr. Berry’s wife - just for association, not as a judgement). Just note here that she is low carb proponent and not as good a source, in my opinion, of information as Dr. Jamie Seeman that you are looking for, but she may be to your liking?

Neisha has been a nurse for many years including obstetrics. So while Dr Seeman may be a better resource, I don’t think Neisha’s knowledge and experience are anything to sneeze at. She might not be the only voice I’d listen to, but I’m happy to have her in the choir.

Some people worry about gluconeogenesis adding to their blood glucose as a bad thing. Saying that it is not significant is meant to sooth those people. To my understanding, gluconeogenesis is need driven, not supply driven. So if you eat more protein than you need it will only be turned into glucose if you need glucose. Seems to me breastfeeding is exactly the kind of situation this biological function was made for.


Thanks Ruina. That makes sense. Yes Dr Sherman has a wealth of info and I’ll take these leads and see how I go on a Day to day basis! :pray::pray::pray:

@Scottty1983 A few months ago I conducted a month-long 2-week experiment with a CGM (Continuous Glucose Monitor) and determined that during the whole time my blood glucose remained within the normal range. I eat sub-15 grams of carbs per day, frequently sub-10 (3-4 times per week) and occasionally sub-5 grams, when I feel like I want to win the ‘keto badge of courage’ :heart_eyes:


That is pretty cool. So the device that goes der the skin? It’s amazing how our bodies can maintain a steady stage of glucose eating minimal carbs. So far I’ve been going ok with my supply, eating around 30g a day of carbs - I think total not net - but supplementing with feenegreek and taking daily flaxseeds and brewers yeast. Will see how the next few days go as this was when my supply plummeted last time. Albeit I’m consuming an additional 300-500 calories this time.

Calories matter, but not the way in which we are told they do. The body’s hormonal response to the foods we eat is far more relevant to determining what it will do with the food we eat.

Pregnant and nursing women who fast on a ketogenic diet risk developing euglycaemic ketoacidosis (I don’t know how serious the risk actually is, but there have been cases described in the literature). I’m not a woman, but if I were, my choice would not be to eat carbs, but would rather be to avoid fasting until after weaning the baby.



Did it occur to you that she isn’t keto adapted? And that her cells switching over their machinery from burning carbs to long chain fatty acids doesn’t occur overnight and is neither stress free?


No I’m not fat adapted… since the pregnancy. I used to be before I conceived. I have been eating low carb paleo though for the last 2 years but definitely not keto.


What @anon81060937 brought up is important! I wouldn’t make a sudden change to fuel source while you’re nursing. Generally people recommend cutting carbs (low enough to go into ketosis) and just riding out the effects, but I would make it a gradual change for you. Your body will likely be hypersensitive to any hint of scarcity.
How are you doing?


Thanks Madeline. I’ve been going well, eating around 30-40g total carbs a day with higher calories and my supply is fine. I am also supplementing with breast feeding tablets to supply supply. I’ve been doing this for about a week. I haven’t shifting any weight, maybe a bit of water but that’s fine. My body likes being around 68-69kg. I did break down to 67 when I was following the nutritionists diet but I was starving the whole time felt drained couldn’t workout due to fatigue and lost my supply.
I’m thinking of playing around with reducing carbs a rad or to look at tweaking calories. But equally this maybe where my body is happy at during breastfeeding. I’m probably eating 1800-2000 calories. No fasting and eating when hungry. Sometimes that is before bed which I know isn’t good. We eat an early dinner here around 5pm so by 9pm I’m ready to eat again. My sleep is poor being up several times a night feeding and resettling so I am sure that is impacting on my stress and weight.
Im working out about 30min day separate from my normal daily movement which is quite good anyway.
Prior to this keto inspired journey, I was and have always eaten low carb - under 75g day even during pregnancy but not keto.


Have you been tested for Vitamin deficiencies?

I don’t believe it’s natural for a baby to wake up during the night because it places stress on the mother.

We humans need sufficient Vitamin B12 to produce sufficient melatonin and get a good night’s sleep… a deep sleep. Something to take into account though is that an effective Vitamin B12 supplement will place you in a deep sleep and you may not wake up if your baby is crying and is far away.

The only B12 supplement I’ve found to be effective at raising my melatonin levels has been Jarrow formulas methyl b12. I take the 1000mcg dosage when I need it and it works within half hour. There’s lower dosages available.

Breast milk apparently contains melatonin.


Yes I have and at around 6 week pp my levels were good. I don’t agree with that position that it is not natural I’m sorry. Breastfed babies wake frequently and even do formula fed babies. 4mo is a time where babies sleep changes and they wake between cycles and typically when a lo of babies are sleep trained. I don’t sleep train and we co sleep and feed on demand. Breast feeding is more than food and thirst is connection comfort emotional expression etc
I will look into that supplement for sure though. I take a methyl b 12 from seeking health due to mthfr.
The waking doesn’t bother me and I did it with my first for over 18-24months. It’s such a small amount of time. The weight from my first pregnancy didn’t shift until she was 12-18months really.

Completely natural! That’s why so many new parents complain of sleepless nights… :unamused:


I disagree but I would need to reveal something to make you see why it’s unnatural. It does seem true at face value because most humans are living the same type of life.

It’s like how humans used to believe that the earth was flat and keep believing that this is the way of the world and nothing will ever change. Blah blah blah until indisputable truth comes out and speaks for itself.


I think if you understand the physiology of infancy feeding and sleep you understand that night wakings are normal and necessary. Adults don’t sleep through the night and wake several times but know how to put themselves back to sleep. Babies don’t. We decide to wait until they are developmentally ready to self settle rather than “training” our children to sleep. That’s just our choice. Breast milk is digested in around 2 hours so a shorter 3-4 hr block sleep is normal. Babies don’t just seek out the breast for food its thirst comfort reassurance reconnection etc
Anyhow possibly not the appropriate place to discuss babies sleep. Happy to keep it to keto talk. :blush:

So you’re saying that every other mammalian offspring that wakes regularly during the night to feed, with no interference for humans, is also unnatural? All mammalian babies wake throughout their sleeping time to feed, the lack of waking would be unnatural, and anyone who tries to make a new mother believe her baby’s natural behaviour is somehow wrong, is extremely unhelpful.

Kittens & puppies need two hour feeds right through the night for the first few weeks, then three hourly, and when you’re lucky, four hourly. One of my friends is currently nursing these week old squirrel kittens day and night with them needing feeding every two or three hours…


I’m not sure I understand your point. I’m saying firstly that babies sleep and how a mother chooses to mother is deeply personal. If she breast feeds or formula feeds, or feeds on a schedule or by demand or sleep trains or not or co sleeps or not. There is no judgment on my part. I was responding to a comment about suggesting it was unnatural that my baby waked regularly at night and that it wasn’t natural.
I am saying it’s common and ok/normal for babies to wake as needed at night. Equally if the baby sleeps longer stretches at night that’s awesome! It just is what it is! I’m just saying that it is biologically normal for babies to wake regularly at night no different to the daytime. Babies do have longer stretches at night purely because of drive to sleep (melatonin etc) snd so their first cycle might be longer than 2-3hrs but typically more frequently after 3am due to changes in hormones.

I didn’t come on here to discuss baby sleep, I came on here to seek support about breastfeeding and keto. That’s it.

As my post shows, it’s a response to @anon81060937, I haven’t actually read your posts on the subject.
