Four Hour Body – Slow Carb diet results
From the end of March until July, both my girlfriend and I went on Tim Ferriss‘ Slow Carb diet described in his excellent book called “The Four Hour Body“. I’m posting our results here as the diet was very successful for us and I hope this will inspire others!
I started the diet with my first measurements on March 31st and my girlfriend Nanna followed the week after. Notice that Nanna also did waist measurements, which is why her numbers are higher than mine. Also notice that you can find all the numbers in the Excel found at the bottom of this post.
And our weight results – I lost 13,6 kg and Nanna lost 9,4 kg over the course of these 16 weeks.
I’d definitely also recommend taking pictures to follow your progress but don’t do like I did below – take them somewhere where the light source is above you, so you can actually see the contours in the photo. I think the below pictures would have looked much more significant had I done this.
For breakfast, I normally made eggs in the micro wave when I arrived at the office. I mostly added kidney beans and peas.
..and for lunch, a slice of ham with peas, kidney beans, lentils, spinach and whatever else I found interesting.
We’ve now stopped the diet and switched to a healthy way of living/eating and excercising a lot (which we did only in small amounts during the Slow Carb diet). And since we’re now used to a more controlled way of eating, this hasn’t been too hard to switch to.
A couple of notes on the diet in random order…
- It was easy – anyone can do it. When you learn to postpone all the bad stuff until Saturday you’re well on your way and be sure to measure/weigh yourself weekly.
- I have been overweight as long as I can remember! Don’t think you can’t get results if you’ve always been big(ish).
- We had our cheat day on Saturday and weigh-in/measurements on Wednesdays.
- I normally ate the same for breakfast and lunch during the week while Nanna varied for each meal
- We did not stick 100% to the diet but did the best we could (except for a birthday party we attended on a Friday and a skiing holiday/business trips)
- You will clearly see that what you ate before wasn’t good for you. I was never the first to mention when to eat lunch and I definitely ate less than everyone else for breakfast.
- I wish I had more data to see whether the up/down motion of my measurements would be consistent over a longer period of time
- I’ve never been in better shape than now! Running with 14 kg’s less really makes a difference (surprise!) – I run pretty much every day now, fx. http://runkeeper.com/user/LarsHenriksen/activity/46360355
- You will have to/want to spend money on new clothes! I’ve had suits retailored but I have lost too much weight for it to look good.Well, at least belts can get some new holes
- There’s a lot of info about the diet/recipes/4 hour stuff in general – have a look at Four Hour Body Recipes, 4-Hour Life, Slow Carb Foodie etc. (and of course follow Tim’s blog) and search around!
- If anyone have any questions about this, please post them in the comments and I’ll do my best to answer them!

Wow! Great results Lars, you both did really well. I wish I too had taken pictures of my before self – I just didn’t want to really record my gut back then though!
I weigh myself through-out the week, not daily, but most mornings – I don’t worry about fluctuations too much, as long as there is a roughly downward trend. Though finally started exercising again, so hopefully my weight will go up again now (from muscle!) while my body fat carries on going down.
Good luck, and let me know how you get on going forward with this.

Hi Liam,
Thanks! And I really didn’t want to take those pictures either, but definitely served as a motivator.
I have also been weighing myself more than just weekly but as you mention, the fluctuation can be quite misleading!
Thanks, also the best of luck to you!

Wonderful to see such great results Lars! Good job, both of you. It is also great to see that you were able to “exit” the diet and take the healthy living aspect to heart with a new way of eating that you can sustain in the long run.
Best of luck, and thanks for sharing your results. P.S. I hope Tim takes you up on your offer for a cold one in Denmark!
Cheers, Stephen

Hi Steve,
Thanks a lot! And yes, we were also very happy to not see the weight go straight up after the first month with no diet – only 1 kg up and 0,5 cm in a few places, but that was to be expected.
Yep, hoping that the results can be useful for some people out there. And yes, that would be pretty cool (he already favorited my tweet, so that part was already really cool
)
Thanks,
Lars

THANK YOU for this. Reading success stories like yours keeps me “on the plan.” I’m 5’2, over 60, and have 40 pounds to lose. Articles like yours are so helpful…

Hi Lars,
I´m at the first week of the diet and the results are already quite impressive. Tomorrow I´ll have my first cheat day

Hei.
I was wondering about berries, can they be eaten?

Sorry, Mette, don’t think they’re allowed. Too much of a sugar spike
