6 weeks ago I started intermittent fasting while following my paleo diet. The reason I am doing this is to help with insulin resistance(I have lost 30 pounds but not one inch from my stomach as I seem to be storing all my fat there) and weight loss.
Roughly about 7 months I gave up my daily/4 daily cups of coffee - I may have 1 cup for the occasional treat and maybe have 1 de-caf a week. When I started the intermittant fasting I was read that it was a good idea to drink coffee, for the energy, feeling full and positive effects of moderate caffeine. I do my fasting on Mondays and Fridays and have between 1-3 cups of coffee during the day.
I am now on day 9 of my second whole 30 and am having issues with being tired, finding it hard to focus in work.
Does anyone have any experience in this? I can't tell if its due to me re-introducing coffee on my fasting days that is causing this tiredness/lack of concentration. Or perhaps is over all lack of nutrition.
I am eating well - large amount of fat, good protein and fruit/veg(carb) - also diary and alcohol free.
Any advice would be welcome!

You are not getting enough carbohydrates and probably also salt. The paleo diet eliminates sugar (glucose/fructose) with the emphasis on the fructose. You still need carbs.

Also be careful with IF if you think you may have adrenal issues and/or low thyroid function AND you're maintaining a fairly high exercise level.
I was doing pretty low carb Paleo for a while and I now believe that I was over eating protein and under eating good carbs which was a factor in some fatigue and adrenal/cortisol issues I've been working through.
Your body may actually need a higher calorie intake for the amount of exercise/activity you're maintaining, and fasting ends up being an additional stressor.

I am not doing full paleo yet but we're getting there both me and my wife. I also do intermittent fasting (with or without bulletproof coffee). I tend to do them on more slow days. Not working days. So I do it friday evening to saturday afternoon and then again from saturday evening to sunday afternoon.
It's definitely brought me over some "humps" and having cheatmeals on saturday evening I tend to gain between saturday and monday which I don't anymore.

Try taking in a bit of fat as you fast, perhaps you're not yet fully adapted to burning fat. Something like a bulletproof coffee, or a bit of extra virgin coconut oil. Sip this slowly, when first exposed to MCT/coconut oil, if you go too fast, you'll get the runs.
While you won't be doing a full fast anymore, you'll still get the same benefits, because MCT oil or the MCT oil in coconut oil will convert into ketones, the same way as your own fat stores do.
Most of the benefits of IF come from turning off the insulin response, and autophagy - neither of which are effected by consuming fat. As long as you avoid carbs and protein while you fast, this will work in nearly the same way. If you over do it, you just won't be burning your own fat stores.
