Intermittent Fasting Disrupting Keto

(Louis Valliere) #1

Hello, I’ve been doing keto for about three+ weeks. I previously did it for more than a month, but then took two days off and had to start over.

Last week the school I substitute for was on vacation. For two days I didn’t feel like I needed to eat breakfast or lunch and so didn’t. From there I started only eating between only 12-8pm. This worked pretty well during vacation, but when I started subbing again I could tell that after breaking my fast at lunch, I was going off of ketosis. I was getting the drowsiness symptoms that lead me to start the diet in the first place. They’re actually even worse than usual.

Is it too soon to start IF since I’m not fat adjusted yet? I feel like I might need to eat more carbs…?
Yesterday I felt really bad when I got back home and ate half a banana. I felt better and later my piss strip show that my ketones were ‘Large.’

Thanks.

You don’t NEED any carbs, so that’s not it.

Fasting is easier when you’re fat adapted because your hunger is so diminished when your system is happily burning stored fat for fuel. IF goes beautifully with keto and isn’t going to knock you out of ketosis.

The symptoms you described are carb withdrawal (keto flu), and eating half a banana is a burst of sugar that your body is looking for. You have to fight through that. Plus, half a banana is half your daily allotment at about 10g of net carbs.

If you are indeed getting knocked out of ketosis, it’s likely because of hidden carbs, not from fasting.

I agree with TJ - fasting triggers ketosis in even the heaviest carbage-eaters. It will not kick you out of ketosis.

If you’re tired - electrolytes are probably the answer. Especially while fasting. Salt in particular is a greater need when fasting and doing keto.

Yup, you are not into keto long enough to be over the keto flu, as someone else mentioned. Giving in and eating a banana, which is the worst thing you can do, is only going to set you back. If anything, eat more veggies, cheese, or meat, not sugar or startch, and maybe increase you salt intake. Drink lots of water and power through. When you feel the most like eating off plan is when you shouldn’t. It will help develop you will power in the future.

Ok. Thanks guys. I guess I’ll just stop doing the intermittent fasting until i’m adapted.

Yes…fasting shouldn’t keep you out of ketosis in fact when starting the ketogenic diet for epilepsy in children they actually admit the children to the hospital and start them on a fasting protocol for 48 hours plus to get them into full ketosis before starting with the regular diet protocol.
