7 day carb test (from Wired to Eat): Day 1 – White Rice
AVOID WHITE RICE!!!!!!!!
….. says my blood glucose test kit.
Although I’ve been quite selective about my carbs for the last 2 years (e.g. sweet potatoes, white rice or low fructose fruits like cranberries, raspberries and passion fruits), I have never tested how my body reacts to each of them. In fact I’ve learnt about this from some Instagram posts. Biohackers are now testing which carbs are truly good for you, and whether you should further ditch bad guys. Robb Wolf recommends this test in his book Wired to Eat, saying that we should eliminate carbs, which can raise your blood glucose level too much.
What he say is true. We all have different DNAs and foods can have various impacts on our body. Even the ‘good’ carbs, for example, which are on the green list on the Bulletproof Roadmap, may have bad effects on you (e.g. raises too much blood glucose level). We just don’t know until you test them.
But how can we do this? Very simple! All you need is a blood glucose meter I bought from aliexpress.com, it only cost me $16.16 with 50 stripes and needles.
Then you select a food with 50g of net carbohydrate. That’s it. Then test your glucose level 2 hours later. My fasted glucose level was 4.8mml/L this morning, which is normal. Then I warmed up of white rice I cooked yesterday, which weighed 64.5g prior to cooking, which has roughly 50g of net carb. I just used the calculator from myfitnesspal app.
I have never eaten just a bowl of rice like this. No salt, nothing. It did not satiate me at all. It just kept on teasing my hunger, it was a horrible feeling!
OK, 2 hours passed slowly. No brain fog or anything, just hungry.
The result? My gadget showed 7.8mml/L!!!!!!!!!! With the safe carb, the result should be between 4.4-6.4mml/L, so I guess rice is no longer an option for me. I will retest at one point with 25g of rice again, but I think I just avoid it all together. It was quite a shock because I love rice. But I knew this was the case – it explains how bad I felt when I was in Japan, when I ate rice twice a day.
I don’t want to do this every day but I certainly want to continue testing different carbs, even some gluten. Very occasionally I do eat a pizza at the local restaurant, I would love to try pizza bread as well.
If you want to know the test in details, visit Robb’s website. https://robbwolf.com/wiredtoeat/7daycarbtest/ There is a very good FAQ section on this test.
There is another good article to show how ‘normal’ people did the test. I hate quoting something from the Sun newspaper in general, but in this articles, you can see how their readers went through with the tests. https://www.thesun.co.uk/living/3185454/three-sun-readers-take-test-to-find-out-which-carbs-they-can-eat-safely-and-which-they-should-avoid/
