The keto diet: “This may be the most effective diet I’ve ever attempted”


Over 310,000 people have signed up for our free two-week keto low-carb challenge. You’ll get free guidance, meal plans, recipes, shopping lists and troubleshooting tips – everything you need to succeed on a keto diet.

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



I was very excited to begin this two-week challenge because I have come to value the ketogenic approach to health and wellness. Having the shopping lists made going to the market a breeze. My cupboard and refrigerator already had about a third of the items on the first week’s list, so that made shopping a bit easier. I noticed that I am not throwing out as much produce that I sometimes have to do. My refrigerator is neater and more organized. I LOVE HAVING A MENU FOR THE WEEK!

Since I live alone, preparing the meals for my dinner and then lunch the next day has proven to be very efficient and time-saving. Some of the meals I like so much that I feel guilty eating them. As far as weight loss, I lost a couple of pounds the first week. I tested with the ketone strip and was able to determine I was in ketosis. The second week I continued to lose with another couple of pounds.

However, all that being said, beginning this new approach to eating is a bit more challenging over the holidays. I will not say any more on that subject. But I shall continue to do the best I can with the help of Diet Doctor website and menu options.

Many thanks,


I think this may be the most effective diet I’ve ever attempted. While I didn’t lose a lot of weight (at 47, it’s becoming increasingly difficult to get the pounds to shift), it is slowly coming off, and the diet itself is very sustainable and easy to continue.

I’m looking forward to the next few months of continuing to reach my goal weight with delicious and filling recipes. One of the things I appreciate the most about this diet is the ease of preparation. So many others seem to insist on cooking three separate meals/day, making the process far too difficult and time-consuming. Eggs for breakfast, leftovers for lunch, and something new and delicious for dinner fits my family’s lifestyle perfectly!

Thanks for making this tool available for everyone interesting in low-carb!


I really enjoyed the fact that I could get this challenge for free for two weeks. I lost 15 lbs (7 kg) and several inches. I was amazed at how hard the first 4 days were (more the body’s reaction to getting sugar out of it and breaking the habit of wanting something sweet to satisfy) I stuck to the diet to a T and continued even after the two weeks was complete.

Tough time to start with Christmas right in front of me. I did enjoy a few days at Christmas and ate nothing close to what I would eat normally, I paid attention to what went into my mouth.

I then decided I still need a little help loosing the last 10 lbs (5 kg) or so, so I signed up and now with Christmas past I will continue on until my goal is reached.

I feel so much better. I was at a point of how to get started and needed a push with results so I would feel the difference and be able to feel better. I was disappointed that many places would cost hundreds of dollars to get started. This came at a time when I did not have hundreds of dollars.

Thank you for the offer to start for free for two weeks, you challenged me to improve my health, body figure and feel good and energized again.


I learned a lot during my low-carb challenge. I will very soon be 60 years old, all of that time I’ve been in the obese or overweight BMI.

I was on my first restricted diet at age 7 and when most children would be playing with toys I remember looking at window displays in chemists at Limits biscuits believing that if only I had the money to pay for them I could also have a normal body weight.

I’ve been on a diet most of my life, at periods of high stress I’ve struggled to stop overeating. My most successful diet was in 2011 when I ate a low-carb very low-fat diet but that ended with high-stress levels all illness.

Adding so much fat to my food has seemed so alien to my past but I have felt good lost weight and more importantly fat percentage I’ve also stopped snacks and returned to the no breakfast routine of my teenage years. I like it so far and plan to continue this journey.


Hello Dr. Eenfeldt,

I have been gluten free for a long time. Long before it became a fad. So some of this diet is not hard for me.

What I find difficult and costly is mayonnaise. I know making your own is best, but it is a hit and miss process for me. Using regular full-fat mayonnaise works best for me.

I sometimes worry that I am eating too much fat even though I have read the studies and your information on it.

I am not 100% true to keto and I want to be. Eating and cooking with others is sometimes a challenge and people generally don’t understand. I have lost some weight and I am happy for that, but have so much more to lose.

More tips on cravings, substitutions, using dairy or not, is always helpful.


I really enjoyed the 2-week challenge. I’ve been looking for a way to control what I eat and drink. I was 292 lbs (132 kg) and drank about 2-3 liters of soda a day. I also ate take out for every meal.

I found the adjustment pretty easy and only had the keto flu for two days. After three weeks, I am down 16 lbs (7 kg) and haven’t even had a soda. I look forward to continuing this plan and losing even more weight.


I am writing from New Mexico, I’m a 71-year old woman with 15 stubborn pounds (7 kg) to lose.

The menus posted for the 2-week challenge are “doable” but I must admit that I’ve reached the point where I do not want to fuss with cooking. I made it through the first week and started to see a weight loss but then – the holidays set in and not only did I lose my focus, I gained all weight lost and then some.

Today is a new day though and I will start all over. The problem with starting over is that it is harder to keep excited about going keto.

Your website is helpful, thank you.
