Here are new amazing stories from the people who’ve taken the challenge:


Dear Andreas,

Many thanks for giving me the opportunity to follow this diet. It never occurred to me that will work after trying different others without effect.

I am a type 2 diabetic with lots of other long-term health issues and on polypharmacy.

After the first week, I managed to get rid of bloating, regurgitation, nausea and abdominal pain despite being a bit constipated. My energy level increased enormously and my shortness of breath and chest pain disappeared.

Also the stupid hunger and cravings from diabetes disappeared. In the second week I managed to do intermittent fasting, until lunch only, for 3 days. In these first 2 weeks I lost 2 kilos (4 lbs). With the Duncan diet I lost 1 kilo (2 lbs) after 3 months.

This week, I will be doing 3 days intermittent fasting, continue with the LCHF diet as we had BBQ with friends on Saturday and all the unhealthy snacks available then did not appeal to me at all.

My aim is to get better with my health and if possible, to loose weight to ease my osteoarthritis pain and improve my breathing will be great.

I am not extremely obese and I am tall (1.72 m and 91 kg – 5 foot 6 and 201 lbs) but due to too many health issues I was like zombie for the last year. I am starting to feel alive again so many thanks again.

All the best to you and all the people on this magnificent diet.

Have a great day and an even greater week. I will definitely have.

Kindest regards,

So far, I have found the low-carb high-fat diet to be a positive experience. I perused the recipes for a few days before I summoned the courage to start, so really, I have not finished the two-week challenge yet, on day 10! I think I was actually afraid of stopping the sugar!

After the first week, I was down 1.5 kg (3 lbs), and I think finally not having the sugar cravings. For whatever reason I am finding having no starchy carbs and sugar easier to manage than having a small amount. I have not been hungry, and aside from a bit of nausea at the beginning, I am having no keto flu type symptoms. All good. In my past diet experiences I have found the second week more challenging to comply with. So far, no problem. I have signed up for the free month and am so impressed with the support literature and information on your site that I will likely continue. I am a Canadian living in New Zealand and enjoy the international content of your program.


I’ve been on a low-carb diet for a month now. I joined after two weeks. After three weeks, I’d lost 11 lbs (5 kg). I didn’t follow your meal plan schedule. I just used your recipes, well I actually mixed and matched. I’ve been a diabetic for three years and had gained weight and glucose was going up. I didn’t want to go on medication and was upset that I’d been following the Diabetic Clinic’s plan so was very confused by the trending results. My family doctor suggested I go on the LC diet. She gave me your web page and a YouTube: Dr. Sarah Hallberg.

I followed you challenge to answer any questions or situation which I didn’t understand, e.g. flu-like symptoms. My doctor told me to drink bouillon, but with high blood pressure, I didn’t think that was a good idea. Found out through your challenge why I needed it.

My glucose and blood pressure have returned to normal, although I’m still taking blood-pressure medication so I’m monitoring this closely.

The challenge was good – easy to follow. Changing my eating habits wasn’t hard. The only think I missed was bread. I’ve made most of the low-carb breads, but haven’t found anything that will do the trick for me. I won’t give up, I’m not a fan of coconut. Three years ago, I was told to eat more carbs and eat snacks. Well, that didn’t work. This challenge was more in line with the way I ate my whole life, except potatoes, pasta and rice were my basic meal, which was usually only once a day.

Your recipes are delicious, and I haven’t been hungry once. My special burger place (homemade burgers), makes my burger in a lettuce wrap – whole burger only has 2 carbs.

I call this a low-carb diet, but it’s not a diet. It’s a way of eating. There are people who need your daily guidance to stick to their plan. I didn’t do this to lose weight, I just wanted to control my glucose without medication. For me it’s working all around anyway. So thank you.

If I don’t follow your daily plan, will I lose all your wonderful receipts? I hope not.



I’m so glad you allowed this reply. I am 59-years old and grew up in the era that fat is bad. So I am TERRIFIED to eat as much fat as I will have to eat to go low carb. That said, I do believe this is the only thing that is going to work. I am trying to read as much material as possible this week so I can do the shopping and planning this weekend. I agree that planning is key. I have an exaggerated increase in belly fat, that I’ve never had before. So I am really hoping I can get past this fear of fat and be successful.

I do have one question – can I make this work by watching my grams of carbs, fats and protein? For instance if I choose to start at 40 g of carbs, how do I know how much protein and how much fat to shoot for? Answering this question would help me tremendously.

I appreciate all your time,

Love this challenge, I started it on a Monday May 22nd because I already had plans for dinner with my family. The meals were great and I was not craving for anything and believe or not had a little more energy. Really didn’t experience any side effects, I also slept better. My doctor said last August that I was close to being pre diabetic and prescribed a low-dose cholesterol medicine, so for my next check-up hoping I have reversed his diagnosis. After all said and done with the challenge I lost a total of 7.6 lbs (3 kg). My plan is to continue on with this low-carb diet and hope to reach my goal in the next several months.


Actually, I think it’s excellent. Very well thought out to encourage, support and most importantly to inform people of the science and most contemporary schools of thought in diet and nutrition. I haven’t come across another website quite like it in that respect without having to buy something at the end!

One thing that would be a boon is a food diary (I’m sure you know about www.nutricheck.com) that you can add the meal planner dishes, or own recipes, which is carb counting orientated, not calorie counting. I would be prepared to pay a higher monthly subscription for this especially if there was an App for my iPhone too.

I’m not a diabetic, but my husband is 72 a T2D and in the last two weeks his fasting glucose levels have reduced from 18 mmol/L (324 mg/dl) to 6.9 mmol/L (124 mg/dl) which is fantastic! He’s still taking metformin, gliclazide and Januvia but it’s still early days and I’m interested in comparing his HBA1c levels, after his next blood test, to the last one.

He’s a typical example of someone presenting with metabolic syndrome: overweight, triple heart bypass (August 2013), high BP, high cholesterol and prescribed statins.

Thankfully, I’m not overweight and I started this diet/lifestyle to avoid metabolic syndrome – prevention is better than cure, so they say!

I’m enjoying experimenting with the recipes everyday and quickly realised just how unappetizing and tasteless a low-fat high-carb diet was, in addition to being no good for you either. So this diet/lifestyle is a real re-discovery for me as it is the diet of my childhood, where we ate until we were full with no snacks in between meals and none of my immediate family are overweight.

I look forward to consulting with this site everyday not only for inspiration for each day’s menu, but to educate myself from watching and listening to qualified professionals who are pushing the boundaries and challenging dyed in the wool beliefs for the benefit of humankind with no mind for personal profit. How refreshing!

Kind regards,

Hello Andreas,

Thank you so much for your two-week challenge.

My husband has been type 2 diabetic for about 3 years. Lately, it seemed that his medication wasn’t helping anymore and he was planning to tell his doctor that he wanted to try a different medication.

I stumbled upon this keto diet thing one day while on Pinterest. We both grew up a in meat and potatoes kind of families and never did very well on traditional diets. This was so different that we decided to give it a try. That’s when I found your website and we got started on the two week challenge. My husband’s sugar numbers averaged around 200 mg/dl (11.1 mmol/L) first thing in the morning; after just two weeks he’s down around 150 mg/dl (8.3 mmol/L). Woot!

We plan to continue with the keto diet and I look forward to seeing how much he will continue to improve. Oh yeah, and we’ve also both seen a drop in our weight. ;-) This is the first time I’ve ever been on a diet that makes me lose weight throughout my body and not just in my wrists or something. Lol

Thanks again for this great program and all the support you offer.

Hollie and Bill

I was very nauseous and had an upset stomach for the first two weeks and I have not lost any weight. I did like the recipes, but my body was not used to eating so much fat. I usually eat low-fat everything.

I have to try to figure out why I am not losing any weight, because that is my goal – lose 15 lbs (7 kg).


Honestly, I didn’t like it. I stopped after a week.

I usually eat a paleo-based diet. This keto diet didn’t have enough vegetables for my liking. It was too low carb. I eat around 100 g, slightly more, per day.

Positives of the keto diet. Liked all the dairy, I did feel full longer during meal times (but after 5 days I felt bloated). It has shown me that I need to reduce my carb intake lower to lose weight. I’m aiming for 50 g per day. I’ve cut down on fruit throughout the week with more above ground vegetables. The daily emails were great motivation.

Your infographics on low-carb nuts, fruit and veg etc. are very useful.


I am going to start over. I had carbs twice during the 2-week period. I liked the recipes because they were easy to follow. I also liked the meals. They tasted very rich and I felt full. I don’t like having to cook everyday. I used to cook every Sunday and would make enough food to last for the week, mind you it wasn’t as fresh as it is now. I also like the fact that you cook one time for 2 meals.

I only eat chicken breast, ground turkey, and fish – so didn’t know what to do on nights that I had to cook pork. I did substitute ground turkey for the beef.

I don’t feel I lost any weight but I did feel better.

Going to try again. I would like to continue eating like this. I will get back to you in two weeks.


Beautiful website and professional videos. Thx for the info, although I am still confused about daily application. One helpful item would have been snack ideas. I’m sure it’s just in my mind, but I still want to nibble throughout the day.

Thanks for the info…

Thank you for asking,

I discovered your plan when talking to a neighbour here in Toronto. She is succeeding and as a previous Aitken’s follower, I decided to give your two-week plan a go.

Atkins was not easy and the fact that they are selling these obviously carb-laden products is very disappointing.

I prepared in advance for your two weeks. This is something I have never done and honestly it made all the difference. I did not throw everything out, but I did move things out of the way, to the back of the fridge or cupboard or to the bottom of the freezer so that I did not see them every time I opened things up.

I shopped and planned the meals. I cooked meals as suggested, with a few variations, but I would say within 90% of your plan.

I have lost 6 pounds (3 kg) and am feeling like I can continue with ease.

Now, I am not affected by food allergies or diet restrictions . I am a meat eater and open to new things. That is why I feel I have succeeded. I think I may have convinced my brother as well.

The food grouping sections that help identify carbs was very revealing and the visualizing from those really helped. Being able to call up your help from my iphone is also very reinforcing.

The only other thing I can think of would be a “carb counter”. I am using MyFitnessPal. So, a system like this using your information would be great, to make eating out easier.

Your videos and ongoing flow of information and tips are very helpful. Please continue.

Now, onward and down!!
