Poody, some people find this to be the case. i suggest adding a Green Smoothie to your daily menus. Not all at once, or you may get the trots. Or at least some uncomfortable feelings.
The benefit of Green Smoothies is that the blended greens are more available to the beneficial bacteria in your gut than any other form of greens. By nourishing them, you promote gut health and function. Yes, you are eating lots of roughage, but maybe this is a new regime and you gut can’t process it.

Here’s a recipe: 1st time you make it, don’t use all 2 cups of greens — maybe 1/2 cup. Then increase the amount.

Green Smoothie 77 calories 0.3 g fat 1.6 g fiber 1.7 g protein 31.3 g carb 30.7 mg Calcium PB GF HINT: this makes enough for three 6-oz servings, so it will save you time on the next 2 breakfasts.
2 cups mixed greens – spinach, romaine, lettuce, chard – roughly chopped 2 oz banana, sliced 2 oz berries ½ apple or pear 12 oz tomato juice [such as Knudsen’s organic] 10 ice cubes

Put the fruit and greens in the blender and swirl it together on ”high” just long enough to break down the fruit and greens. Set blender to “low,” add the juice and ice cubes. Process until smooth. Put what you don’t drink today into a jar in the ‘fridge. Next time you use it, shake it well. If you think it has become too thick, feel free to thin it with water or OJ.

or eat dried figs every day [1-2]

Hi Poody!

I just saw your post whilst I was looking for the March Challenge!

Sounds like you’ve sorted the problem now, but thought I’d chip in anyway as I know it is a problem for many people.

Yes, I also always include green cruciferous vegetables on my Fast Day. Recently I’ve been having steamed 19-20 sprouts OR a large helping of steamed broccoli as part of my evening meal. The calories are so negligible and they are super filling and obviously full of fibre. So it is great that you are already doing that.

However, echoing @fasting_me above, the other piece I would stress is that if you are struggling with constipation, you are probably not having enough fibre during your five non fast-days?

On my non FDs, I tend to have a vegetable & avocado smoothie for breakfast which includes 2 big tablespoons of linseed (flax seeds).

I also include c100 mls of home-made kefir (beneficial bacteria as @fasting_me indicates above)

I sweeten my daily veg & kefir smoothies with Lakanto/Monk Fruit (a zero calorie/zero carb sugar that is NOT carcinogenic!) and also c25-50g of creamed coconut, which is delicious, tasty and 16% fibre. Otherwise, yes I sometimes use dried figs or prunes or dates to add fibre and sweetness, but generally I try to avoid fruit at breakfast as it tends to spike my blood sugar and make me hungrier sooner.

Good luck!
