Here are new fantastic stories from the people who’ve taken the challenge:


Hello, I am a 65-year old New Zealander and have just done the 2-week challenge. I lost 9 lbs (4 kg), so I am really pleased as it makes a good start to a longish journey to get to a reasonable weight. I found the recipes interesting and importantly, tasty, and over time got into the cook two meals habit making life easier when doing shift work.

I will continue this as it suits me well and is essentially simple and not horribly expensive either. Thank you for the great support.



I am a 69-year old woman and live in Mill Bay, British Columbia, Canada.

After one week I had lost 5 lbs (2 kg), after two weeks not so much 1 lbs (0.5 kg). My blood sugar have improved. I now don’t have to use Humolog insulin at meal times and my Lantus insulin at nighttime is down as well.

All in all very pleased with blood sugars. I will try and cut back on protein and some fat, so maybe I can lose more lbs.

Thank you, Diet doctor!!!

I was very pleased to receive a link to your site from a friend who has lost 50 lbs (23 kg) over the past few years following an LCHF diet. I loved the meal plans and all of the recipes on your site. I love to cook and have tried many of your recipes, all delicious.

I actually started the challenge right away (instead of waiting until the following Monday) and stayed on the plan for the past three weeks. I am down a total of 11 lbs (5 kg) and will continue on this plan. I want to lose another 30–40 lbs (14-18 kg) and I do not feel the least bit hungry and find it really easy to follow.


Hi there!

My name is Joan; I’m 58 and live in Vancouver, Canada.
I took the low-carb challenge after struggling with weight gain and not being able to change my feeling of low metabolism.

In two weeks, I’ve lost 4.3 pounds (2 kg) and my waist went from 33⅜” (85 cm) to 31½” (80.5 cm).

I found the daily recipes and tips easy and encouraging. I’m going to keep going because I feel great and am excited about how this is working for my body.

Thank you so much.

My name is Penny and I live in Toutle, Washington. I am 53 years old, I have type 2 diabetes. I was put on insulin about 8 months ago.

I stumbled across your website a couple weeks ago. I figured what could it hurt to give it a try. Within a few days I stopped taking my insulin and a few more days I had to stop my glipizide. I lost 8 lbs (4 kg) and 2 inches (5 cm) from my waist in two weeks.

I was so surprised at how fast my sugar cravings and hunger went away. I look forward to continuing this lifestyle. Hopefully I will be off all my medications in the near future.

Thank you so much for sharing your knowing without charging an arm and a leg. We need more people like you in this world. God Bless You!!!

I really enjoyed the two-week challenge. I’m 52, menopausal and haven’t found anything to shift the weight but I lost 2 kg (4 lbs) over the two weeks. I will continue with low carb until I get to my ideal weight.

Thanks for a great two weeks.


Hi, friends,

I completed the 2-week challenge and dropped a pant size. I’m staying off the scales for a while, so I don’t know the pounds lost, but I’m thrilled with already decreasing one size.

The meals on the challenge were tasty and easy to prepare. Also, the daily e-mail encouragement kept me focused and inspired. When time permitted, I visited the website (I’m a member) and picked up more knowledge, recipes, and inspiration.

I’m committed to this way of eating and look forward to losing several more sizes before I’m all done. I’m living in Kentucky and I’m a zippy 63-year old.

Thanks so much, Dr. Eenfeldt!
