The success stories
What kind of results can you expect on a keto diet? Hundreds of people have sent us their success stories. Check out a few for inspiration:
Fantastic – I loved it!Kick-started my low-carb journey, easy to follow, love the app – it’s brilliant!
I don’t have to wonder and think about what to eat. All I have to do is shop.
This challenge was user-friendly and a great resource.
I was initially ambivalent about getting started, but the daily emails made it super easy to get started. I didn’t have to log in to the website to find my daily plan. It was sent straight to my email.
The recipes were easy to follow and very tasty. I also felt that I didn’t waste a lot of food because many of the ingredients are consistently used. I highly recommend this website to get started.
Hello Diet Doctor staff,The keto challenge was wonderful, not so much a challenge but a joy. 😊
I followed the advice on other Dr. Eenfeldt videos on your site, where he suggested eating as much of the permitted foods to satiety rather than counting macros, which I would find tedious.
I am so pleasantly surprised! I thought I had a sugar addiction. It seems I don’t. On day two — and ever since — I’ve had ZERO cravings for sweet food. This is remarkable for me. And I have lost 13 pounds (6 kilos) in 4 weeks. (I did a week of keto before and after the challenge.)
I am continuing to eat keto as I love it.
Thank you for your excellent website. It’s so informative.
Frequently asked questions
How much weight will I lose on the 2-week keto challenge?
This is highly individual, but most people lose between 3 and 15 pounds (1.5 to 7 kilos) in the two weeks.6 Some lose more, some lose less.
Why does the challenge last two weeks?
Two weeks are enough to determine your own response to the diet and to get through early difficulties — like removing sugar from your diet. It’s enough time to start experiencing the true benefits of a keto diet and to know if you want to continue.7 It’s not a huge undertaking, and basically anyone can commit to this challenge for two weeks. Are you up for it?

Does this challenge contain recommendations on exercise?
No. Exercise is great for health and strength, but it’s not necessary to lose weight.9 We do not recommend changing your exercise habits for this challenge.
This is because it’s much more effective to focus on changing ONE habit at a time.10. You can always start exercising later after completing the 2-week challenge.
Can I still drink coffee, tea, or alcohol on this program?
Yes. There are plenty of keto ways to do that.
I’m a vegetarian, can I do this program?
Meat and fish dishes are prevelant in this particular challenge. However, if you want to try a lacto-ovo vegetarian low-carb diet, we have vegetarian low-carb meal plans, including shopping lists, available for members. Free trial one month.

Scientific studies now prove that low-carb and keto diets are often more effective for weight loss and improving certain health markers when compared to other diets.
This has been demonstrated in several meta-analyses of all top studies. For example, this one:
Ketogenic diets also tend to reduce feelings of hunger:
Low-carb diets can help lower or even normalize blood sugar, and thus, potentially reverse type 2 diabetes:
In this study, people on a low-carb diet experienced decreases in cravings for carbs:
This small non-randomized intervention trial found promising effects:
A low-carb diet is generally a low FODMAP diet, and the latter has stronger scientific support for improving IBS symptoms:
Journal of Gastroenterology and Hepatology 2017: The evidence base for efficacy of the low FODMAP diet in irritable bowel syndrome: is it ready for prime time as a first-line therapy? [moderate evidence]
Here are stories of improved lives from different people:
Many studies, including this one, have shown that a keto diet is effective for weight loss — even when the participants are allowed to eat as much food as they need to feel satisfied:
Nutrition & Diabetes 2017: Twelve-month outcomes of a randomized trial of a moderate-carbohydrate versus very low-carbohydrate diet in overweight adults with type 2 diabetes mellitus or prediabetes [moderate evidence] ↩
In a survey, 86% of people completing this program reported losing weight:
The idea that fewer carbs is usually more effective is mainly based on the consistent experience of experienced practitioners and stories from people trying different levels of carb restriction [weak evidence]
The only intervention study – to our knowledge – that compared different carb restriction levels were a small trial that found as the carb intake went lower, the trend was towards greater weight loss and greater improvements in cardiometabolic risk factors.
Also, better glycemic (blood sugar) control is likely with lower carb intake:
Journal of the American Dietetic Association 2008: Restricted-carbohydrate diets in patients with type 2 diabetes: a meta-analysis [moderate evidence, downgraded as it’s comparing effects between different low-carb trials. There is no RCT comparing low carb to lower carb.]
Exercise has some effect on weight loss – but probably a smaller effect than most people expect:
The American Journal of Medicine 2011: Isolated aerobic exercise and weight loss: a systematic review and meta-analysis of randomized controlled trials [strong evidence for about 1-2 kilos of weight loss]
Exercise interventions might be a bit more effective for overweight and obese adolescents (10-19 years of age):
