Yesterday I decided to do some blood glucose (BG) testing while drinking orange juice. I’ve been turned off from OJ because I tested my BG after drinking it in the morning and it was high – like in the 170s. I tested again in smaller quantities, but I always felt really hungry after drinking just a little so what’s the point? Well, I’ve since learned that the hunger you feel when you eat fruit is your true hunger. Low carb dieting raises stress hormones, which reduce appetite. No wonder people lose weight on low carb – their cortisol is suppressing their drive to eat. Until 6 months later when they (might) realize their thyroid doesn’t work anymore. Anyway, hunger means there are no stress hormones running around, so eat, dummy. One problem with this though – I have been hesitant to keep eating juice or fruit because I didn’t want my blood sugar to be high all day. What a conundrum!
Well, I decided to turn to science to get some answers. I drank 12 oz of orange juice at breakfast and then 3-4 oz every hour. Here were my readings:
- Fasting blood sugar: 127; Temp/pulse 98.1/79
- 9:00AM – 172
- 10:00AM – 139
- 11:00AM – 115 (temp/pulse was 98.6/79)
- 12:00 – 115
- 1:00 – 74 (after 30 minutes mild/moderate exercise)
- 2:00 – 97
- 3:00 – 106
Huh. So for some reason there’s a big spike at first but then blood sugar is low all day. Weird! I did it again today to see if the results would replicate. Had breakfast with about 10oz juice. Here’s what I got:
- Fasting – 124; temp/pulse 98.0/85
- 9:00AM – 119 (tested at 1 hour and 20 minutes after breakfast)
- 10:00AM – 106 (temp/pulse 98.8/75)
- 12:00 – 101
- 1:00 – 107
- 2:00 – 112
At that point I stopped testing every hour. Good enough! I did take one more test though, after 30 minutes of stationary biking. Blood sugar was 72, similar to the previous day after biking. I thought it was weird that I didn’t feel hungry at all with blood sugar that low. Then I remembered…About 10 years ago I used to do martial arts (Aikido). I would train hard for an hour and a half, and leave the dojo feeling really good, but not hungry. Then about an hour later I would become ravenously hungry. Now I understand why! The workout was causing a stress response – cortisol and/or adrenaline were suppressing my appetite. After relaxing for an hour or so the stress hormones would lower and my true hunger would be revealed. This is why Peat (and others) are opposed to exercise – it raises stress hormones. I guess I knew this intellectually, but it makes a lot of sense now having experienced a complete lack of hunger after exercising, while my blood sugar is getting very low. Interesting. I’ve been doing 30 minutes of biking and 15 minutes of yoga per day for the last week. Maybe instead I’ll do 30 minutes of yoga and 15 minutes of weight lifting. Less continuous stress.
The other thing on my mind has to do with progesterone. Ray Peat did an interview that was aired last week, in which he answered lots of questions that had been submitted by listeners. Well, prior to the interview I submitted a question. My question appeared in the second hour of the interview, and was as follows:
I’ve recently started taking Progest-E, and it has helped my cyclical mood symptoms very much. I’ve been taking it days 14-28 of my cycle. I hate to stop taking it because I have PMS (moodiness) the day after I stop. Would there be any harm in just continuing to take it non-stop for a while, even if it means I miss a period or two?
Dr. Peat’s answer:
I’ve known quite a few women who took it every day and kept cycling without any problem. But what they should be aware of is that if you take a little bit extra just before the expected time of ovulation it will trigger early ovulation, and then if you stop taking it or take less it will bring on an early menstruation. So if you’re going to take it every day, it has to be every day the same amount.
If you’ll remember I really REALLY didn’t want to stop taking my Progest E after day 28 last month. In fact, I kept taking it and taking it and finally stopped against my will to have a period. Then I started up again on Day 4 of my cycle – a full 10 days before I was supposed to start up – because the symptoms of high estrogen were unbearable. I was depressed, bitchy, and puffed up. It sucked. So I started my progesterone early. Well, surprise surprise…my period came 10 days early. And it’s very possible I dosed a little too high before ovulation. That Ray Peat. He sure does know some stuff.
More news: after about 10 days of probiotics my gut is still messed up. I tried taking two teaspoons of potato starch today (far less than the 4 Tbs many people are downing at one time) and still…not good. Gut mad at me. I don’t know what it will take to fix what is wrong, but I’ll continue with the probiotics for now.
And the orange juice…3-4 oz an hour.
Oh one more thing – suddenly my body is ok with cheese. I have completely stopped eating fatty chicken and most eggs, cutting my PUFA intake to almost nothing. Could that be why my asthma isn’t kicking my ass right now? I had like 4-5 oz of cheese today…and no problems.
Ok, blood sugar…progesterone…and PUFA. I can’t deny it any more. All the crap he says is coming true for me.
I think Ray Peat is right.
