Hopefully by eating Primal/Paleo for a while now you have adapted yourself to a low carb, high fat diet. The main benefit of becoming fat adapted is you can now burn fat, the fat you eat and, if you don’t eat, the fat on your body! Did you catch that? The “if you don’t eat” part? That’s called fasting! Hopefully, you’ve done a little bit of that in your Primal/Paleo journey.
The LCHF meals we eat should satisfy your hunger more than the high carb crap the Standard American Diet tells us to eat. The more satisfying your meals are the less you’ll eat at a sitting and the longer you can go without eating again! Its hard to break that thought cycle of eating “3 square meals a day”. Sometimes I wake up and I don’t eat breakfast, or if I eat breakfast, I’ll skip lunch. A lot of times I don’t eat dinner! Just eating one meal a day at the same time means you’re doing a 24 hour fast! I have done lots of 24 hour fasts. I have done 2 and 3 day fasts and I did do a 5 and 7 day fast!
If you’re new to fasting, you must read Dr. Jason Fung’s the Complete Guide to Fasting. Another good read would be Jimmy Moore’s, Keto Clarity and Mark Sisson’s, The Keto Reset Diet.
And you must also consult with your doctor about fasting especially if you are Type II Diabetic, insulin resistant and/or pre-diabetic. I was Type II Diabetic and had high blood pressure when I started out, but I worked closely with my doctor.
I did have some large swings in my blood sugar levels, but I was always ahead of things because I checked my blood sugar often. So check your blood sugar often. I check my ketone levels at the same time every day to get an idea of the direction I’m going in.
When fasting, you can have bone broth, tea and even BPC (but no dairy).
