Is it safe to have cheat days on keto?

How did you feel soon after and then the next day?

Felt weird drinking the drink and quite odd on the way up, but 75g of glucose in one hit after virtually none wasn’t unexpected… once I’d bottomed out it was ok then I think slightly elevated for a day or so after and then back to “normal” after that.
I guess its about time for another one… but I’m not sure I want to ingest that much glucose…

I wonder what that would look like if you carbed up (200+ grams a day minimum) for 5 to 7 days before the OGTT, at least that‘s what Dr. Atkin’s recommended before an oral glucose tolerance test?

I would imagine a lower spike but I have no intention of trying that…

If you ever do decide to do it post here on this thread, that would really be valuable information to a lot of people?

(bulkbiker) #110

I would certainly post the OGTT results but have no intention of poisoning myself…

I’ve had a couple of small “dinner” meals consisting of only a cup of plain white rice (no butter or oil) during the past couple of weeks.

I didn’t notice any effects from it, either acutely or during the next day. I continued with my usual 16:8 baseline fast (rice at 1900 and lunch after 1100) and there wasn’t anything worth mentioning at that time. I suspect there was a BG rise, but without a monitor I don’t have any useful data.

(The goal here is dabbling in PHD principles now and then to see if there are any effects, positive or negative.)

Of course I understand your disdain for carbs but that would be really neat if you could demonstrate your glucose tolerance after all the effort you put into this metabolic repair?

(bulkbiker) #113

Not especially “neat” for my poor body… although I can understand why you might want to know…
Maybe you could try the OGTT after your resistant starch experiments and see how you get on?

(Bunny) #114

Lower blood sugars as would be expected.

(bulkbiker) #115

i.e. you have no results?

(Bunny) #116

Those were past experiments and now you want me to break out all those dusty glucose monitors sitting on the shelf?

Now that I’m thinking about it, maybe I will get me one those fancy continuous ones.

(bulkbiker) #117

Would be really “neat” ?

(Bunny) #118

Not as ‘neat’ as yours would be because you had diabetes, I never have had diabetes?

Wow, Mark - this is fascinating! I’m no stranger to graphs like this (my T1D + appropriately-dosed exogenous bolus insulin + steak + keto chocolate mousse + 6 hours = almost exactly this picture, but with a much, much later spike than yours), but it’s really, really interesting to see that a T2D in remission after a shedload of glucose has such a dramatic spike.

I’m very impressed with the 4.0mmol/l just over two hours later - that’s quite some insulin action going on!

Now I’m on much less insulin than I used to be pre-keto, I avoid glucose altogether - I’m not needing to treat hypos with it, and when I do dip a little low, I simply turn down the tap on my insulin pump a smidge. I used to have several hypos a day in my insulin-chasing-carbs-chasing-insulin-chasing-carbs-chasing-insulin-etc-etc-etc days - thank goodness I’m off that rollercoaster at last (yay keto!).

Not surprised you’re not keen to take 75g glucose in one hit to test this again - blimey…!

This all confirms the protocol for TKD, established nearly 20 years ago. It’s well known among the Fitness Community that the post training glucose/dextrose/glucose-d 40 g consumption creates an approx. two hour insulin spike. That’s why the protocol advises waiting at least that long before resuming fat consumption.

Great experiment Mark. Thanks for posting it.

Dr Boz on youtube is studying this. She has graphs on 2 patients and shows their glucose and ketones after fasting and eating. One patient is a diabetic since 20 years and the other is a younger, quite slim and sporty woman. They show different results. The young woman who is nondiabetic can fast and then eat without any disturbance of her blood glucose.
