Unfortunately, Rice and potatoes are two of my main food item. It is due to our food tradition. And not following 80-20 rules at all. The end result, increasing weight very rapidly. Frequent indigestion, flatulence etc are not unusual.
Thank you for reminding us of what we need to do to keep our gut healthy.
I know how you feel because potatoes are almost in everything here where I live. Those excess carbohydrates damp our insulin sensitivity and get us fat. I'm struggling with potatoes myself, but if you set your mind to it it can be done.
