Wondering how long it takes to lose weight on hflcI just wanted to talk a little bit about what you can expect when it comes to weight loss on a low-carb, high-fat diet. If you’re like me, when I first started reading about eating low carb, I got very excited about these stories of weight loss just seeming to happen as if by magic, with the pounds falling off more quickly than you can count.

However when I started eating low carb – that didn’t happen for me. Not straight away anyway. It took a fair bit of adjusting and reading and trial and error before I found my sweet spot and really got to grips with what was happening with my body.

Here are a few of the main points I learned. If you’re experiencing weight loss stalls, or you just want to know what to expect, hopefully, this will help you.

You Really Have to Watch Your Protein Intake

Low carb, high-fat diets that are geared around getting you into a fat-burning state must include only moderate amounts of protein. When I first started, I used the 0.8g of protein per pound of lean muscle calculation. This put me at about 100g of protein/ day. My weight loss didn’t start until I tinkered with this and dropped my daily intake of protein to 45-55g per day. At the time I wasn’t exercising, and I am 5′ 8″.

Eating more protein than your body needs will lead to your body breaking down the protein into glucose, keeping your blood sugars high and blocking your keto-adaptation. Now that I exercise more I have increased my protein – but only a little. I still won’t go over 60g a day usually.

Once I dropped my protein intake, the weight loss started, and continued at a steady rate (about 2lbs/week).

Weight Loss Will Only Happen After Your Body Has Healed

How soon you start dropping excess fat will depend on how much healing your body needs to do. Healing will always be your body’s priority. This is why intermittent fasting is not recommended when you first improve your diet. Getting your three meals in a day means you are maximising the nutrients that you are putting into your body, which allows your body to heal more quickly.

Low Carb High Fat Diets MUST be High in Fats!

It took me a while to get over my fear of fats. Just getting my fats to 100g a day seemed like a ridiculously large amount. But the thing is, you want your body to start producing ketones and burning fat for fuel. For your brain and body tot learn that fat is the preferred fuel, you really have to flood your body with fats in the first few weeks to get the message across. I only started to get fat-adapted when my daily intake of fat was between 160g-200g/day.

And, I was only able to do this once I dropped my protein intake to 45g-55g.

Sleep is Way More Important Than You Think

If you are not getting a good 7-8 hours of sleep per night, at a decent time (say from 10pm to 6pm), your weight loss will stall. Your body needs this sleep time to heal, to produce ketones and to understand that you are not living in a stressful state. Stress will hinder weight loss.

Going Too Low in Calories will Hinder Weight Loss

This may seem counter-intuitive, but when I started, I reduced my calories to 1500kcal/day. I initially lost some weight, but then I began to feel tired, and also didn’t sleep so well. At 1500kcal a day, I couldn’t get in the amount of fat I needed. After the initial weight loss, I stopped losing weight and found I wasn’t getting good ketone numbers, and my blood sugars were still too high (signs that you’re not keto-adapted).

I increased my calories to 1800-2000kcal a day and low and behold; the weight loss started again! So strange, but true.

The Deal is -Low Carb High Fat Weight Loss Can Take Time

I found the best way to approach this diet is to think about healing, health, energy and how good I’m feeling. When you focus on these things and look at what you’re eating as nourishment so you can achieve this, the excess weight will naturally fall away. And what’s more, you will feel amazing, and not be obsessing over those numbers. So often I’ve heard that women have so much healing to do that weight loss that keto for women can take more time and patience.

So what experiences have you had with a low carb high fat diet? I’d love to hear from you, let me know in the comments below!

  1. My partner and I have just started Keto 4 nights ago now. I’m still doing a lot of research however so far so good! I am however concerned going into my 5th day on Keto and I have actually put on 1kg! Is this normal and / or is there something I should be doing different. We follow a complete dietry plan for Keto. I want to stick it out as the heath side is great 😀

    1. Hi Jamie, that’s fantastic that you and your partner are both doing keto together! Funnily enough I was just talking to a lady yesterday who has experienced exactly the same thing – one week into keto and she has put on 2lbs. Basically, when you switch to keto and reduce the glucose available to your brain, what can happen is your brain has a mini freak out because it thinks there is not enough food available. And what it does is lower your metabolism in order to conserve energy. This is only temporary until your brain starts to understand that there are plenty of fat/ketones it can burn for fuel instead of glucose which doesn’t take long. What’s important right now is to make sure you are getting enough fats in, and don’t reduce your calories. You need to help your brain and body to learn that there is plenty of fuel available (just not in the form of carbs and sugars!)

  2. Hi there. I’ve been experiencing the same thing nearly a month in and only a pound loss and clothes don’t feel any different but don’t want to give up because I haven’t been having the chocolate and crisp cravings. Haven’t done any exercise because my energy levels aren’t there. My boyfriend on the other hand has lost half a stone despite him cheating occasionally. Should I just be patient? How long can it take to see results? Be grateful for any replies.

    1. Hi Michelle, ah yes I know it can be so frustrating that men seem to find it so easy to lose weight compared to women! My suggestion to you is hang on in there. A month is actually still early days with the keto diet, and although some women find they drop a lot of weight in this time, for others it does take longer. If your energy levels are still low, you are still adapting and your body is not yet efficiently burning fat for fuel. When you are adapted, you will find you have a lot more energy and your hunger levels will decrease. This naturally means you will be moving around more and eating less and weight loss will start to happen. Make sure you are not reducing your calories too much in this adaptation phase… if your brain and body feel like there isn’t enough food around you won’t adapt and your body will hold on to excess weight. It really can be counter intuitive, but for us women, we really need to be nourishing and feeding ourselves in order for our bodies to release excess fat. (Our pesky hormones!).

      So yes, my recommendations are: Do not reduce calories too much, make sure you are getting enough fat (and your carbs are low), do not snack between meals (this can hinder adaptation), try some gentle exercise like going for walks to encourage your body to get efficient at burning fats, keep your stress levels as low as possible and get plenty of sleep. Right now your focus should be keto-adapting. And don’t compare yourself to your boyfriend! Men really are like a different species when it comes to losing weight!! All the best, Joan.

  3. Hi Joan 🙂
    I am eating LCHF 15 days. At the beginning the first week I lost 4 kg, but that is it. I am not loosing weight for 10 days. I don’t eat any carbs.I drinking bulletproof coffee for breakfast, I eat lunch and dinner. I don’t eat snacks, maybe once or twice this week. I eat strictly LCHF , but why am I not loosing weight? I am starting to concern. Should I be?
    Thanks in advance

    1. Hi Marija, it’s perfectly normal to have a weight loss stall after the first ‘whoosh’ of weight loss. Your body is still adjusting to the keto way of eating. Give it time, make sure you are eating enough fats (and don’t go too low in calories as this will not help). Make sure you are getting enough sleep and continue to nourish your body so it can heal and find its balance. All the best!

  4. Hi
    I’m in my second week of ketosis , well I cheated on Mother’s Day but showed trace on a keto stick by The following Tuesday and I’m not cheating anymore but I’ve gained a pound. I’m discouraged and want to know how long I should keep eating LCHF? I think I lost weight immediately last year when I started.

    1. Hi Lauretta, please don’t worry about that pound! Weight can easily fluctuate more than that just because of your body holding on to more water when you eat carbs. Just feed yourself great, nourishing food. Focus on health. Eat when you’re hungry and don’t when you’re not… you’re body will find its balance. 🙂

      1. Dear Joan,
        It’s me again 🙂 . I have something to ask you. As I told you before , I am on LCHF almost a month, without any offense, I eat strictly LCHF. My preference is my health and not the weight loss. Weight loss will come surely as the time passes.
        I have polyp in the uterus, do you know maybe if the polyp will heal , because I am not eating carbs (low carbs) , or get smaller after a period of time?
        Thanks in advance

        1. Hi Marija! In all honesty, I don’t know about this I’m afraid. What I will say though, is I know women have experienced relief and healing from things like PCOS, endometriosis, irregular periods and hormonal health by following a keto diet. So my hope would be that you would notice some improvement. But obviously, I’m not a medical professional so can’t give you anything but my guesses here. I do wish you all the best, I’d be very interested to know how you get on and if you do see some improvements here. 🙂

          1. Thank you very much for everything, I will tell you if there is any improvement. We’ll keep in touch <3
