Have you considered that you have candida/systemic yeast infection? Bloating could be a sign.
I fasted for 16 days in January, yet when I broke the fast with fruit it felt like by guts would explode. I was tested, and found out I have a systemic yeast infection.
Any foods that are converted to glucose are fuel for yeast/candida, i.e. fruit, grains, sugars, dairy etc...
There is an active Candida Forum on this site. Everyone is unique, and symptoms vary widely. Good luck
