Three Days of Nutrition Testing/Study

I mentioned in a previous post that I was going to take part in a nutritional study. I got the kit on Thursday this last week and started on Friday.

Day 1

I attached my continuous glucose monitor (CGM) and started logging my food. This food log is a bit different in that it doesn't share the macros or calories of the food that you input. Like other apps, you can scan barcodes and enter individual ingredients. It's been very easy to us. You can compile a recipe and then adjust it to how much you actually ate, etc.

Everything I put in my mouth except water is logged and photographed. I weigh and measure everything. This hasn't been as tedious as I thought it would be.

Daty 2

My main task besides continuing to log my food was to take a stool sample. With the kit came a special pouch thing that you strap across the toilet to catch your stool, and of course a little sample spoon thing that fits into a sample tube. It was pretty easy to accomplish. The purpose of the sample is to evaluate my microbiome and see how my good and bad bacteria stack up. This will help determine what foods my body will respond to the best. It was interesting to see how the food I ate throughout the day affected my blood glucose.

Day 3 was a busy one.

For breakfast I had to eat 3 "special" muffins. This was a bit rough. The muffins were very sugary, and I was supposed to eat all three within 15 minutes. They weren't huge, but man, they were tough to eat. I was able to drink some black coffee with them, which was a nice counter.

It didn't take too long for my blood sugar to rise and for me to feel a little crappy. I haven't been eating foods with added sugar, so it hit me pretty hard. These muffins were specifically made to elicit a glucose response. I will say though, my glucose didn't rise as much as I thought it would. It peaked at 150 and started coming back down quickly.

After finishing the 3 breakfast muffins I had to fast for 4 hours, and then I had to eat 2 more muffins...UGH!.

These next two muffins were slightly different. They were lower in sugar, although still had quite a bit, and they had more fat. These two muffins had a composition that was supposed to mimic the standard American diet, so yeah, not particularly healthy. I always get a kick out of "Standard American Diet" = SAD, which is right on the mark.

I had to fast for another 2 hours and then it was time for a blood test. I had to lancet one of my fingers and donate four drops of blood on a little card with special paper that absorbed the blood and then allowed the fat to separate. The higher fat muffins in this case were used to get fat into the blood and see how my body deals with that.
After the blood test, I could eat whatever I wanted. I was dying for some real food and had some carrots and hummus and a bit later a greek yogurt. It was great to have some food that wasn't sugary.

I logged my dinner and the day came to a close as far as food logging. I have two more muffins and and a three hour fast on day four, and then from that time forward the food is all up to me, although they have provided a number of different "experiments" to do. I'm looking forward to the next 11 days of observing how my body reacts.
Below is a chart of my glucose today.

The peak with the yellow highlight was the peak after the 3 breakfast muffins. The purple was after the 2 lunch muffins. The red highlight at the end of the day came from my dinner, which was a "beyond burger" on a keto bun with lettuce, tomato, pickle, a tiny bit of ketchup. On the side were a few air-fryer potato fries.

I suspect that the spike was caused primarily by the potatoes. There is some sugar in the ketchup, but not much. Tomorrow I'm going to have the same meal without the potatoes to see what the difference will be.

I'll be putting together several food experiments over the next 11 days, so that will be pretty cool. After that, I just wait for my test results and their evaluation of my two week food log and glucose responses to determine the best food combinations for my gut microbiome.

Don't worry, I won't bore you daily with posts, but I know a couple of people were interested.
 
For reference. This was today's monitoring. The first spike was the last two special breakfast muffins, and the highest spike I've had so far. The lower spike near the end of the day was my same identical burger (I weighed everything to be exact as last night), but I did not have the homemade fries. You can see the spike was not as high or as abrupt up and down. It was a lot more gradual.

The really low lines at the beginning was during sleep where you can see my blood sugar is down around 70 and then comes up a bit before I wake up.

There wasn't any spike for lunch because I had carrots, green peppers, and hummus. I was really wanting something not sweet or baked at all. There was a little bump when I had some grapes and a protein bar a bit later, but not much of one, barely over 100.

This is all very interesting - thanks for sharing and I look forward to more posts. Those first muffins sounded rough! Lol!

All the muffins were pretty brutal. I haven't eaten anything with added sugar for months, and these had a ton of sugar. I did not feel particularly well afterward.

It has been interesting since then to see the things that make my blood sugar go up.

There was a pretty significant difference between steel cut oats and whole grain rolled oats with the steel cut oats slowly going up leveling out and slowly going down while the rolled oats shot up quickly and higher and then crashed right after. It's pretty fascinating to observe.

I'm a geek. :)
