I know there is a long thread on IF already but I have a more specific question regarding such. I’ve done it twice and loved it, felt great, more energy, lost body fat, etc. Both times however I’ve had health ailments pop up that may be related to IF or just coincidental.

The first time, my blood pressure got out of control, I chalked it up to Muscle Pharm Amino Energy however. The second time I got “Central Serous Retinopathy” basically where I built up fluid behind my retina and had distorted vision for 6 months. I can’t find the culprit to this except I know CSR is caused by high cortisol levels. Both times the ailment appeared after 3 months of IF.

So I’m wondering if IF can cause a spike in cortisol levels (before I get back on that train). I also have naturally low blood glucose levels. I’m 30 yr old male, 185#, 5’9. ~14% body fat so I ain’t diabetic.

Go get your blood drawn. I'm in good shape as well, but i have bad diabetic family history. I'm really insulin sensitive although I'm in good health. If I eat bad I feel horrible and I'd put on weight quickly.

That sounds like me exactly too. What blood test should they be running? I get a physical every year and my glucose levels were at 77 last time (fasted). Which isn’t crazy, but I do have hypoglycemic spells every now and then.

I wouldn’t say the IF caused high cortisol but probably the calorie deficit/cardio you were probably doing.

I go to a diabetic center once a year. I honestly don't know what tests they run, but it gives me insulin and lipids and such. You're doctor should know.

You may be spot on with that. It’s been eating me up trying to figure it out but I did read that not giving yourself enough recovery would spike cortisol.

If you really think it's cortisol try taking reduce xt by sns and see if that helps, but I don't think it's cortisol causing your issues.

I actually just had extensive labs drawn, and am doing a saliva test for cortisol levels today...It will be interesting to see the results since I’ve been doing IF for a few months now.

Interesting, keep me posted! There is a home test you can order now too, I believe I saw on the Shark Tank, called EverlyWell. It’s still not cheap though.

I had never heard of that, thanks for sharing! I love this stuff!

I don’t have a baseline, unfortunately, but I definitely feel that my adrenals are much healthier since I’ve been doing IF. My blood sugar used to drop if I didn’t eat every couple of hours, and that doesn’t happen anymore, my energy level is much more steady, and I’ve cut caffeine out with the exception of pre-workout. My sleep has been much better, recovery from workouts is greatly improved, and I can tell I’m generally handling mental stressors much better now.

I'd say so. It's stress in a way, which raises cortisol. Do IF and believe mine is often high, but I'm a naturally stressed out person in general

Also, diabetic or not, cinnamon is naturally effective at controlling blood sugar

IF does increase cortisol. You've just upset your metabolism and your body is trying to figure it out.
By the third month though, I'd say your body has adjusted to the new eating regime. Exercise also increases cortisol, as well as not enough sleep and a whole host of stressors.

Here are the notable things from my blood work and saliva testing. Blood was drawn at 7:45 AM after a workout at 5:30am.

Blood sugar markers:
Glucose was slightly elevated (101 - I think this may have been due to my workout?), but A1C and Insulin were both great.

Cardiac markers - all were in the “optimal” range. Also had “A” LDL particle size.

The only really odd things from my blood work were elevated Calcium and Albumin.

Cortisol: my curve was actually spot on, except for my nighttime reading, which was high, which could have been situational?

I am female, 5’5, 115lbs
