Frequently asked questions

How much weight will I lose on the 2-week keto challenge?

This is highly individual, but it’s typical to lose between 4 and 8 pounds (2 – 4 kilos) in the two weeks. Some lose more, some lose less.

Why is the duration two weeks?

Two weeks are enough to get through early difficulties – like sugar abstinence – and to start experiencing the true benefits of a keto diet. 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.

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 very helpful for weight loss. 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. 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?

This challenge includes many dishes with meat or fish. If you want try a lacto-ovo vegetarian low-carb diet we have six vegetarian low-carb meal plans, including shopping lists etc. (like in this challenge) available for members. Free trial one month.

  1. 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:

    PLOS ONE 2015: Dietary intervention for overweight and obese adults: comparison of low-carbohydrate and low-fat diets. A meta-analysis [strong evidence]

    Here are two selected top studies (RCTs) demonstrating this:
