Ketosis Symptoms & Low Carb Flu Explained


 
>> CLICK HERE to Download this page as a PDF File

What does Ketosis mean exactly, and what are Ketosis symptoms? There are a lot of questions about the Low Carb Flu, also known as “Induction Flu” (based on the Atkins Induction Phase).


If you’ve just started eating low carb and you feel miserable, you’re experiencing the low carb flu.

Ketosis symptoms include:

Headaches, bad breath or a metallic taste in your mouth, irritability (like PMS on steroids! lol), leg cramps, insomnia, nausea, etc.

It basically feels like you’ve been hit with a nasty flu. Symptoms vary from person to person.

The good news is, it means you’re doing it right! The even better news is… it only lasts a few days. 😉

What Is Ketosis?

It is a state in which your body burns fat for energy instead of carbs/sugar. A keto state means you are fueling your body on healthy fats instead of carbohydrates. So that saying that “You need carbs for energy!” is untrue. But you DO need either carbohydrates OR healthy fats for energy, which is why you can’t (or shouldn’t) eat “low carb, low fat”. See Low Carb, High Fat Diet Explained

Your body and your brain actually operate much better on healthy fats. A ketogenic diet is known to reduce seizures, lower blood pressure and cholesterol, control diabetes and chronic pain issues (fibromyalgia, arthritis, etc) and remedy many other common health issues.

The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fuelling brain function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis… –source

The science of Food Combining is an amazing thing!

Unlike a low calorie or low fat diet, there is a science behind how the Low Carb Diet works. By eating 20 net carbs a day max, your body changes from using carbs for energy to using fat for energy. Doing this puts your body in a state of ketosis, which is a huge chemical change – and is what causes you to experience the “low carb flu” for a few days while it is in the process of making this change.

The low carb flu only lasts a few days, and once it passes you’ll feel amazing! In addition to the symptoms I already mentioned, you’ll find you pee a lot more than normal as well, given this is a diuretic diet. You’ll shed unnecessary water weight in the process, and most people experience several pounds in weight loss as well.

How To Get Into Ketosis

Simply eat very low carb (20 net carbs per day or less) and high fat.

Ideally you’ll eat at least 70% of your daily calories in healthy fats.

I use MyFitnessPal with the Keto Hack to keep track of what I’m eating, and to make sure I am getting a healthy ratio of carbs / fat / protein. It’s easy to set up if you use the step-by-step instructions at that link. I shoot for 75% Fat, 20% Protein and 5% carbs from my total daily calories. I don’t actually count calories – just carbs and ratios. You can see example meals and how the ratios worked out in this LCHF 2-Day Food Journal as an example.

How Long Does It Take To Get Into Ketosis?

It seems to vary from person to person, but for me it usually “strikes” on about Day 3 of eating low carb. The relentless headache sets in, I have insomnia or restless sleep, pee incessantly, and get extremely cranky. Fun. 😀

Low Carb FluThis is also when I notice the scales starting to move. Most people lose anywhere from 2-10 pounds during the first week of going low carb, or more specifically with a ketogenic low carb diet.

The scales to the right are mine (and so are the feet, lol). It’s the EatSmart Digital Scale which is Rated #1 on Amazon and available for Amazon Prime and free shipping. I love this scale!!

When I first started a low carb diet, I lost 8 pounds in the first 10 days. That’s typical for someone who starts eating low carb for the first time. If you “yo-yo” too much, your body will “wait to see how serious you are” (yes, that’s my scientific explanation, lol) and it takes longer and longer each time you “start over” to see substantial weight loss.

Anyway, If you eat more than 20 net carbs a day, or eat a lot of processed food (like bars and shakes) instead of “real food” – or if you eat too lean (ie low fat) – you may find it harder to get into ketosis, or that it takes longer.

How To Stay In Ketosis

Simply continue eating very low carb, very high fat and stick to “real food” and “healthy fats”. This will keep your body in a state of ketosis, burning fat for fuel, which is ideal for optimal health and also for weight loss.

This is not a “quick trick weight loss program”. It’s a way of eating to get healthy, stay healthy, and fuel your brain / heart / body in the best way possible. If you use a ketogenic diet to lose weight fast, it will likely work. But going back to a high carbohydrate diet (and processed foods) will put the weight back on just as fast.

It IS important to note though, that you can gain weight eating LCHF (high fat) if you have “cheats”. There’s a science to the way the low carb or Atkins diet works, as I explained above. Carbs and Fat are NOT a good combination. Every time you choose to “indulge” in higher amounts of carbs/starches (more than 20 net/day) you take yourself out of keto state (assuming you got there before that) and have to go through the low carb flu all over again. NOT ideal. Plus yo-yo’ing like that will usually make it take longer and longer for you to achieve results every time you “restart”.

This is not like a low fat or low calorie diet where you can eat a brownie tonight and just got it off tomorrow and be right back on track. It IS a commitment, but it’s one your body will LOVE you for!

Not to mention you’ll be smokin’ hot, lightning fast, and super healthy. 😀

Once you survive the Low Carb Flu that is, lol – and you will! I promise. 😉

    I am having a really hard time getting into Ketosis, I have a killer headache, poor sleep, some loose stools and crabby, but still not testing that I am in Ketosis’s , very flustrated.

    • Alecia says:

      I’ve found that sometimes I don’t get into ketosis when I think I should because there is too much protein in my diet. I learned that protein gets used as a carb when you eat too much of it (not sure of the scientific language for it). Also, my stick doesn’t turn when I have been drinking a lot of fluid. I think your urine can be to diluted to test well. When I’m more dehydrated or haven’t eaten much, it shows up right away. Good luck!

    • Lynn Terry says:

      Shirley,

      The sticks/strips aren’t reliable. It sounds like you have all the symptoms of keto flu! Those symptoms should only last a few days as long as you stay at or under 20 net carbs a day. 😉

    I have been on atkins for m3m weeks now but have not been in ketosis. I have lost 8 lbs and at a stand still. help!

  7. Christine Deferrari says:

    hi, I think I have the low carb flu. Last night I felt aches and chills.. I know it’s not the regular flu. I also had pains in my stomach, I made the cauliflower pot salad and spinach soufflé . Also had the coconut oil for the first time! I woke up still feeling a little achey and I feel like I have to move my Bowles but nothing.. Thanx in advance for some feedback. BTW THIS IS MY 5th day! I did lose 5 lbs already.

    • Lynn Terry says:

      Hi Christine! Congrats on losing 5 pounds in 5 days – that’s awesome. 😀 It may be the food combinations that are giving you stomach pains. Try eating super simple for the next few days – no more than 3 foods / 3 ingredients per plate. That should help.

      Also, coconut oil affects everyone differently. I only use it to make fudge, and eat that in extreme moderation. It’s not necessary, by the way – just a great healthy superfood to add in moderation. 😉

      • Christine Deferrari says:

        Thank you for the response.. I feel much better. I do think it was the combo of broccoli and cauliflower !!

        • Lynn Terry says:

          Broccoli can cause gas pains – and they are no joke. It really doesn’t affect me that way, but I know some people that double over after eating broccoli! Ack 😛

  8. Jess says:

    I think i have the low carb flu aswell. I started my low carb diet on Monday, the next day i got an awful headache. On Wednesday i started feeling stomachache and found it difficult to stay sleep. Today is now Thursday and i have diarrhea. I read a few comments and im the only one to have diarrhea… Im concerned.

    • Lynn Terry says:

      No Jess – you’re not alone with that symptom. 🙂 Fortunately, it will pass pretty quick. Drink some chicken broth. I drink it hot out of a mug like coffee. It replaces the sodium & electrolytes – and makes you feel TONS better. 🙂

  9. Amy says:

    Are fevers a symptom of the keto flu? I’ve googled extensively and found nothing. I have all the other symptoms, as well. On the upside, I’ve lost 11 pounds in 2 weeks.

    • Lynn Terry says:

      Hmm Amy – I’ve never experienced a fever with the keto flu.

      Anyone else??

    • Joy says:

      I have fever, chills, weakness, and extreme fatigue. These symptoms show up when my ketone test strip reads 8.0 or greater. I end up trying to boost electrolytes, which is hard to find as a low carb source. Anyone have a better solution?

      • Lynn Terry says:

        That sounds really odd, Joy…

        Are you drinking too much water maybe?? Try chicken broth – make it strong, add a tbsp of butter to make it even richer, and drink it hot out of a mug.

        Chicken broth replaces sodium & electrolytes lost in the diuretic process of ketosis. Make sure you get plenty of salt (don’t eat low sodium!) and make sure you aren’t drinking too much water. Your urine should be pale yellow (not clear).

        How are you tracking? Are you eating at least 70% fat? I’m not a doctor btw… but happy to help you tweak things to feel better!

  14. Alejandra says:

    Hi!! I’m just beginning this is my second day or firts one lol ( i began yesterday at night jaja) and i guess I already have the symptoms of the keto flu, I’m not sure but i have headaches and something weird happens in my stomach jaja. I have a little o bit of nusea and burps ( i don’t know if the burps are norlma jajaja). I feel my stomach full, but i didn’t eat that much today.. well i hope these stop in the next few days!!

    • Lynn Terry says:

      Hi Alejandra,

      The first few days are the hardest. Hopefully those issues will pan out in quick time for you. By the end of the first week, you should be feeling GREAT! 🙂

      • Alejandra says:

        I’m feeling much better, i still have headache but my stomach feels much better now. 🙂 the good thing about this is I’m learning a lot because 2 years ago I started to do this diet but then I moved to another country and the new style of life of eating healthy was kinda difficult to maintain and every time I was beginning the diet the symptoms appears and i used to think because maybe the food i was eating make me feel sick but now i understand that is because of the keto flu !!!!

      • Lynn Terry says:

        It really does help to know the science behind how Low Carb works, and what’s REALLY going on in your body. 🙂 Chicken Broth really helps with the symptoms during week one (or anytime you find yourself going back through “Induction Flu”) as it replaces the electrolytes & sodium lost during this process.

  15. angela says:

    can you go into ketosis even if your on phase 2. i feel cold a lot of times. sneezing a lot runny nose no appetite but i am making sure i drink plenty of water ? when i do eat i eat a good breakfast before my workout other wise i have no appetite for the rest of the day 🙁

    • Lynn Terry says:

      Hi Angela,

      The Induction Flu wouldn’t cause sneezing or runny nose – that sounds like allergies or a cold. A suppressed appetite is normal for a low carb diet. But lack of appetite could also be a sign you have a cold, especially if you’re not eating super low carb (enough to have the lack of appetite associated with a lower carb ketogenic diet). If you continue to feel bad, or it gets worse, definitely see a doctor.

    have been lowering carbs last two month, think im ready to jump to completely low carb diet. gonna start tomorrow. have been keeping carbs under 90 for last month but have adjusted my MFP account so hopefully that helps.

  19. Paul says:

    Hi Lynn, I’m on day 3 of the keto diet & these headaches are awful. I’m taking tylenol, because I can’t sleep at night & during the day, the haedaches are a pain. I’m committed to make this a lifestyle change, so I’m all in…headaches and all lol. I’m keeping my meals simple (eggs, chicken with skin, avocado, and real coconut milk (not the carton crap, the canned ine with all the fat) for my plain black coffee). How am I doing? Do I need to change anything?

    • Lynn Terry says:

      Hi Paul,

      Day three is always when it hits me too. I get insomnia and relentless headaches, as well as leg cramps. The best solution is to drink (or sip on) chicken broth – as it replaces electrolytes and sodium lost in the process of going into ketosis.

      Fortunately all of those symptoms will pass in a day or two and then you’ll feel fabulous. 🙂 Until then: chicken broth!

  20. Kristin says:

    I started with a weight loss clinic and I was told to try to stick with 1200 calories per day…aim for 30g of protein per meal and no more than 15tsp of sugar per day. Meaning low carb obviously. I have been doing this consistently for almost a week now. The first couple of days I felt great but as the week has gone on I get off and on again headaches, feel a little nauseous at times and get chills seems to be later at night? I have been getting about 10tsp of sugar per day so maybe I’m not getting enough?? Also have a little trouble with constipation…drinking lots of water though. I do feel a difference in my clothes and know there is loss but haven’t weighed in yet.

  21. RhondaD says:

    I’m on day 11 and thought I was dying last night. My head felt weird like dizzy my arms and legs felt like they weigh 100 pounds each and I could not sleep as I felt sick from the dizzy. I hope this doesn’t last much longer!!!!

  22. Amber D. says:

    Hi! I’ve been in the Induction Phase for a little over two weeks. I don’t have a lot of weight to lose (I lost over 80 pounds a few years ago and have mostly kept it off), and I consider myself to have good muscle tone, but the scale was going up again and I am a total carb junkie!! :O I needed a change. One week in, my husband and I did two days of intense, rugged hiking. A week later, my muscles in my legs are still incredibly sore and week! I am strictly following the 20 carbs or under, and I drink loads of water! Anyone else experience this kind of lingering muscle fatigue? Also, I’m still experiencing some nausea?

    • Lynn Terry says:

      Hi Amber,

      When you say “I drink loads of water” – that makes me think the muscle fatigue and nausea may be related to that. See: http://www.travelinglowcarb.com/4884/how-much-water-should-i-drink/ It may just be that you’re flushing out your sodium and electrolytes. The quick fix: Drink chicken broth. Even if it’s from keto flu (or induction flu), chicken broth will do the trick. 🙂

      • Amber D. says:

        I actually found that article last night after I had posted my question and thought that might be me! Thank you for your quick response! I will cut back on the water and see if that helps. I tend to be an excessive drinker (coffee, water, diet pop), and I would guess that I typically drink around 100 to 120 ounces of water, not including the other things I drink!

        • Lynn Terry says:

          Try that and see if it helps. 🙂 Drink chicken broth anytime you feel “icky” for a quick fix too until your body pans out. I use the canned Campbell’s broth like you would cook with – just heat as directed and sip hot out of a mug. *cheers*

  23. angii says:

    I vomited so bad the first day I gave up…but I’m ready to start over.

    • Lynn Terry says:

      Hi Angii,

      Vomiting is not a normal occurrence, especially on your first day eating low carb. It’s just real food (meat & greens) – nothing that should make you sick at all. I would have to guess that by sheer coincidence something else caused that…

      • me says:

        I also vomited badly on the second day. definitely NOT a stomach issue, because I know what that feels like. and this felt like a bad hangover not a bug. plus I found tons of posts on people who vomited during their keto flu.

  29. denise says:

    Not sure why I am “barely” in ketosis, but anyway, here is the question – does the higher the ketosis level equate to faster fat burning? In other words, if I am in trace ketotis am I burning fat more slowly than at a higher level of ketosis? I hope that make sense.

    Ugh. I’m in keto flu now. Day 3 of my low carb diet and I’ve lost 4 pounds. I just feel iky.

          You’ll feel GREAT from here forward – high energy and losing weight and such. 🙂 Just remember that feeling… if you ever feel tempted to eat off plan – know you will have to go through keto flu ALL over again. 😛 haha it’s a good deterrent!

    I am just restarting this… I am a diabetic and am curious as to how safe it is to go through ketosis. Before my blood sugar wasn’t as well controlled when I’d diet like this. Now I wear a pump and it is so well controlled I hardly evere have to put in carbs or blood sugars as I am no longer eating carbs and bs are below 120. I still am getting a small amount and sometimes my bs will drop low. With out having to go through the big long ins and outs of insulin production or lack of and how ketones can build in a diabetics body and cause problems what will I do once I start the keto flu process? If any of this makes sense…..

    • Lynn Terry says:

      Hi Shelly,

      That’s way out of my scope of knowledge unfortunately. I know we have a lot of diabetics in the low carb challenge group if you want to join us there and ask your question: https://www.facebook.com/groups/lowcarbchallenge

      Have you talked to your doctor about it? From what I understand, a healthy ketogenic diet is great for diabetics – but most doctors seem to want you to eat higher carb and lower fat for some crazy reason. I’d definitely do some research on that and talk to others with your specific type & meds!

    Morning. I’m doing the low-carb diet since last Sunday. By Wednesday I got the flu symptoms for 3 days. Then they went away for two days but came back now for three. I have severe nausea but I cannot throw up, and lasts a good two minutes each time & it’s bad!! When will this end or is this something to worry about. I’ve done the chicken broth but effects don’t last long. Lost 7 lbs in 10 days so far….as I’m writing this I’m getting an attack right now….. Okay I’m back. What happens with taking normal meds? Any help is mucho appreciated. Thx

    • Lynn Terry says:

      Hi Val,

      What do you mean by normal meds? For what?

      Did you eat off plan, or eat higher carb somewhere in between to force keto flu again? How are you tracking?? I would love to know your usual fat/protein ratios.

      Maybe something you’re eating is not agreeing with you? I’ve never been nauseous like that… except when I was pregnant. 😛 No fun!

    Hi glad to hear that headaches are normal with low-carbs. I am in the third day of it. My husband is ready to carry me to emergency-room. I have just kind of gone cold-turkey with the carbs, and eating things that I know have zero or very low carbs. What about boiled peanuts, they are a starch and high in carbs, right?

    • Lynn Terry says:

      Drink chicken broth. 🙂 I like Campbell’s canned condensed broth like you cook with – and I mix 3/4 can water with 1 can. It replaces the sodium and electrolytes lost during the diuretic process of going into ketosis – and helps with those symptoms!

      It should be going away anytime now though. It only lasts 2 days for me, but it’s different for everyone.

      If your boiled peanuts don’t have a label, just Google it. I’m not sure on those, but I do know peanuts are one of the higher carb nuts. Pecans are the lowest carb / highest fat nut on the list.

  46. Brenna says:

    Hi guys!
    I’m currently on the atkins diet, just started Tuesday. I believe the phase is called induction? Anyways , does anyone have a hard time getting over all the oil from meats and butter? I’ve honestly always been someone that eats a lot of poultry so adding a lot of meats is a little hard. I had some steak and eggs this morning and I couldn’t get over the oil taste. Does this pass?

    • Lynn Terry says:

      Hi Brenna,

      The first week you might feel a little nauseous but that’s as much from Induction Flu as anything. You don’t have to eat a lot of meat & eggs or oil and better. There are plenty of healthy fats that won’t taste oily like that. 🙂 I like pecans and walnuts, very high fat. Avocado is great too – very high fat. Also egg salad, deviled eggs, tuna salad, grilled salmon – all great choices!

      • Brenna says:

        Thank you I appreciate all of that info! I thought we could not have nuts during induction?

        • Lynn Terry says:

          Hi Brenna! I don’t do Atkins or programs/phases, I simply eat 20 net carbs max and 70% fat minimum. If you are doing the Atkins program, just go by that and wait on the pecans & walnuts. Those are the lowest carb / highest fat nuts on the list, by the way.

          • Brenna says:

            First off: Lynn – Great site, and TONS of helpful information! Thank you for all your hard work!

            One thing I wanted to clear up for Brenna is the nuts question: Actually, according to Dr. Atkins himself, Macadamia nuts are the lowest carb/highest fat nuts (which is why he recommended them for the “Fat Fast” – for helping extremely metabolically resistant people enter ketosis) and are definitely encouraged during the Induction phase, especially for dealing with cravings* (page 279 of the book referenced below). One ounce of macadamia nuts have 3g of carb and a 90% fat content**. Ten halves of pecans have 4g of carbs, and are 87% fat.

            For anyone else interested, other low carb nuts Dr. Atkins recommends in his book are: walnuts (1oz) 4g, Brazil nuts (4 nuts) 2g, Almonds (12-15 nuts) 4g, Pignolias (1oz) 3g, Pumpkin Seeds (1oz) 4g.

  47. Luke says:

    I’m only on day two and I’m already feeling flu like symptoms, is it an actual flu or an i duction flu?

    • Lynn Terry says:

      Hi Luke! It usually hits me on day 3, and the symptoms vary. It’s not an actual flu (head cold) so if you have head cold/flu symptoms you may have a bug. This feels more like you got hit by a truck. Although some people only experience a funny taste in their mouth.

  48. Andrea says:

    Hi, it’s my third day on the diet! I have the regular symptoms everyone else is having! Mine aren’t too bad! However I’m experiencing indigestion… Something I almost never have. Is that a symptom of the keto flu too? No one else says they are having indigestion so I’m just curious!

  49. Prathna says:

    I started Atkins induction 6 days ago and over the past 2-3 days I’ve been having bad headaches, so irritated, feel almost nauseous, waking up in the middle of the night, dizzy when I stand up, and PMS type stomach pain with occasional diarrhea. Also I’m vegan…is that why my symptoms are so bad? I’ve normally heard of people having a few of these symptoms not ALL together in this combination!

    • Lynn Terry says:

      Hi Prathna, Welcome 🙂

      I get screaming headaches and leg cramps myself, and *extreme* irritability. But as long as I stay on plan it only lasts maybe 2 full days at most for me. So just know it WILL pass.

      It’s hard to say how much of that is keto flu symptoms, and whether there may be another culprit. Maybe something new you introduced into your diet over the last week that is upsetting your stomach?

  50. Marisa Montgomery says:

    I have been in induction for 11 months now and have lost 45 lbs. I’m still eating 15-25 carbs. a day in vegt. only. I’m still losing (mostly inches) but it has slowed down. I am not that active so I’ve not increased my carbs. How long can I stay on the induction phase? Can I go another year on induction?

    • Lynn Terry says:

      Hi Marisa,

      Yes, you can eat a healthy ketogenic diet for life actually. I do. 🙂 I keep it really simple: 20 net carbs max, 70% fat minimum. How are you tracking? I’m happy to help see if there’s something you can tweak to start losing weight again.

    Hi Lynn I am on day3 I’ve got cramps the whole body and my throat feels like something is stuck on it, is this normal

      Hi Zaza,

      How are you tracking, and how much water are you drinking? If you’re drinking water, make sure you don’t drink too much. There are some bad myths out there that will make you sick (like drink half your body weight in ounces, wrong). Make sure your urine is pale yellow. Any darker and you should drink more water. Any lighter or clear – and you should drink less.

      Also, don’t eat low sodium. That’s not healthy on a LCHF diet, as it’s a natural diuretic diet – and you’ll end up with muscle cramps and headaches.

      The keto flu is different for everyone, but assuming that’s what it is it always passes for me within 24-48 hours. Drink chicken broth – it will replace the sodium & electrolytes lost during the diuretic process of your body going into ketosis. That will be the quickest thing to help you feel better.

    I’m on my second day of induction and I’m having throbbing mid back pain. Should I be worried?

    • Lynn Terry says:

      Hi Chickitee,

      That’s something I would see your doctor about if you feel it’s a concern. Two days in you shouldn’t be experiencing any “symptoms” so I doubt it’s your diet causing that. But as a precaution – how are you tracking? And are you keeping protein at 25% of your total calories or less? You do want to be cautious about eating “high protein”…

    I found this article while trying to find out why I’m waking up feeling like garbage. Weak, sweaty, and like clogged in my arms. It goes away with water and movement, and I usually feel better after eating breakfast, but that movement is difficult because I feel so weak. Does this sound like the ketosis flu?

    • Lynn Terry says:

      Hi Lavender,

      How long have you been eating low carb? And how are you tracking? Also: how much water are you drinking per day? I ask because it could be any number of things. Not enough healthy fats, too much water, may be keto flu if you’re in the first week or so…

      • Lavender says:

        I am on day 4 and tracking via the LifeSum app. I drink about 10 8oz glasses of water a day.

        • Lynn Terry says:

          Keto Flu usually hits me around day 4 too, so that’s probably it. It passes quickly if you stick it out. Just make sure you’re getting at least 70% of your calories in healthy fats.

          Drink chicken broth too. Not the low sodium kind. Hot out of a mug is really nice to sip on – you can add butter to make it even richer. I like the Campbells condensed broth like you cook with, mixed a little strong (instead of 1:1 water).

          The chicken broth replaces electrolytes and sodium lost in the diuretic process of your body getting into a state of ketosis.

    Just finishing up week two of 20carbs or less. First week lost 7.2lbs. This last week…1/2lb. Is this normal?? I feel I’m doing all that I should be and going to the gym (spinning, swimming, core/weight training). Feeling frustrated…On a positive note though…my arthritis pain in my knees has almost completely vanished…almost…is that normal??
    Morning…2.5 eggs/2 strip of bacon.
    28 almonds for a snack
    Tuna Wrap for lunch with mayo/spinach and a low carb wheat tortilla
    Chicken or some other meat for dinner with some veggies or a salad..(all low carb)
    Sugar free jello for dessert….

    This is pretty typical but does vary…
    What should I being doing different..if anything??
    I do snack on bacon and cheese sticks during the day

      Hi Jodi 🙂

      Congrats on your great weight loss so far, and kudos for taking control of your health!! Yes, it’s totally normal. It’s a diuretic process, getting into ketosis, so you drop water weight immediately.

      It’s common to experience a brief “hold” or even slight fluctuations on the scale during week 2 and/or 3. That’s just your body adjusting to so much weight loss so fast. The key is to keep doing what’s obviously working – don’t change a thing! 😉

      How are you tracking? Are you tracking your macros to make sure you get at least 70% of your calories in fats? That’s important both for energy & weight loss, given the science behind the way this works…

    Ok….this is day 7 and just got off the phone because I have a nurse calling back. Like 4 days ago, I had sweats, shortness of breath and indigestion. I do have heart issues but I hope to get in today to just be checked on the safe side of this. I was really scared, especially with the shortness of breath. I had sweats for 4 days. Today…hmm a small headache and chicken broth will be bought today. This just goes to show all of us what These carbs have done to us. This sounds like coming off of drugs…which….I think carbs are a drug for many of us.
