The 2-week keto challenge: “It’s life changing”


Over 590,000 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 fantastic stories from people who’ve taken the challenge:



My husband and I tried the two-week challenge together. I am 39 and he just turned 40. We were unhappy about how out of shape we had gotten when a friend shared her success with keto.

We found the menu plan the perfect jumpstart/ transition into ketogenic eating. We both lost about 10 pounds (4.5 kg) each and were amazed with how satisfied we felt, how much energy we had and how cravings disappeared! Thank you for all the information, support available and especially the recipes!

Thank you,

I think the low-carb challenge has been great, life changing really. I have lost 10 lbs (4.5 kg) during the initial two-week period, and am excited about the future.

I am much more focused on what I am digesting and realizing that I have been eating and drinking the wrong things for the past 54 years.

I am also experiencing other positive side benefits, liked decreased digestive issues, bloating and joint pain, which my personal care physician once related to too much dairy, which was hard to take as a life long resident of Wisconsin. I now relate those issues to the gluten, wheat, breads, etc. These issues have also almost completely gone away on keto. I also have more energy, feel mentally more clear, have less back pain, and feel generally much better than before I started.

Co-workers and family members say I look great, thinner, and that even my face looks thinner.

Thank you Diet Doctor, I do believe I will be a ketogenic consumer for life!

To those who may be considering Keto, I say take Diet Doctor’s 2-week low-carb challenge, what do you have to lose, other than some unwanted weight?

I am so amazed by this challenge! It went against everything I’ve been taught about eating right and losing weight. At 42 years old, I grew up in the fat-free, low-fat era so the fact that I’m being taught how to eat MORE fat is phenomenal. I’m also a teacher so doing this challenge at the beginning of a new school year worried me because I thought I would get weak from the stress and the dietary challenge, however, the meal plan kept me focused.

I am also a sugar addict/carboholic without a thyroid, so I worried about the keto fatigue but I didn’t get it once. In fact, my head felt clearer and I slept like a baby. On top of feeling better and enjoying all of the simple Diet Doctor recipes, I lost 10 pounds (4.5 kg) in two weeks!

I’m hooked!


I really enjoyed the two week Keto challenge. I found the recipes very tasty and was very organised with my lunch made for work the next day. I didn’t really experience any keto flu symptoms & generally feel less tired & more energetic. I joined the Diet doctor membership and watched lots of videos & films for inspiration.

I lost 6.5 lbs (3 kg) which I am thrilled about and I have decided to continue with the Keto diet and lifestyle. I’ve started intermittent fasting gently by doing 12:12 fast. I believe I am addicted to sugar but have almost no cravings which is fantastic. I am so pleased I tried the challenge & I think your website is fantastic. I’m 50 years old, from Cork in Ireland.


Good afternoon,

I am a 66-year-old man who has been overweight most of my adult life.

I stumbled on to your site about 8 weeks ago and immediately followed your suggestions. The results are staggering as I have lost 11.5 kg (25 lbs), my blood sugar has halved, and I have stopped taking my blood-pressure medication. Further, my demeanor has become much more positive and I have also noticed a great change in the clarity of my thinking and ability to deal with issues. I am a convert and will continue with this lifestyle.

If everyone did this, we would hardly need doctors or pharmacists.

Thank you so much, and I agree totally with your related articles on the corruption from food and pharmaceutical companies.

Best regards,
