Here are new inspirational stories from people who have taken the challenge:



My husband and I decided to start keto together. We plan, shop and cook together. This is new for us. We both found the two-week challenge to be filling, deliciously full of flavor and successful. Between the two of us we ate ourselves out of 25+ pounds (11 kg). We feel better with more energy. This is huge for us.

Thank you for openly sharing the keto info with all the support you offer. We are now looking forward to more discoveries about food and ourselves.


I’m very thankful I found this! In just over two weeks, I have lost 13 pounds (6 kg). I am more energetic and my carb cravings are very, very diminished.


My husband and I, ages 68 and 66, live in Virginia. We are very pleased with the results of the keto challenge and are continuing to guide our new lifestyle with a low-carb, increased fat, “no” sugar framework, along with increased daily walking, biking, and yes, even modified yoga!

Self-care is becoming a vital part of our senior years and we feel so much better already! I’m down eight pounds (4 kg) and my husband lost six pounds (3 kg). We are about to embark on a month-long dream vacation and are pleased that we have a keto foundation in place to help us with food choices as we travel. Thank you, Diet Doctor, for your part in making the keto challenge accessible and successful for us!


Hello, I’m 59 years old. I’m from New Zealand.

I have lost in 3 weeks about 3-4 kilos (6-8 lbs). I know people who do keto and tried keto last year. This time I’m trying to keep below 20 grams carbs per day. Some recipes are too rich, and I’m missing some fruit to eat on keto. But generally the food is tasty and most the time filling.


I was very surprised with the 2-week challenge. Not only did I lose weight but also I could go longer without eating and was sleeping better.
