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 – 7 kilos) in the two weeks.6 Some lose more, some lose less.
Why is the duration 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?
How many carbs are allowed in the challenge?
Meal plans and recipes are designed to stay below 20 grams of net carbs per day (fiber not included), for maximum effect.8
What if I decide to stop before the challenge is over?
You can stop whenever you want. If you don’t want to receive more emails for the challenge, just press “unsubscribe” at the bottom of any email. You can sign up again later if you change your mind.
I’ve tried low carb and keto before but suffered side effects — is it possible to avoid them?
This challenge is designed to minimize any side effects. Should you experience side effects, we provide simple solutions.

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.
The reason for this is that 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 in the meal plans of this particular challenge. However, if you want 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 compared to other diets, low-carb or keto diets are often more effective for weight loss, and for improving certain health markers.
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 very 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 levels of carb restriction was 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):
