Stop making smoothies.
Hmmm, what's wrong with smoothies? We, raw paleo eaters, are already pretty much restricted as to what we can eat, why further remove perfectly good things from the diet? Of course I would agree that a lot of juices is not a good idea - it is hardly paleo, but smoothies are a perfect way to eat, say, raw eggs with a little fruit and a little honey. That makes a nice light breakfast, or lunch if you have to eat in a "social environment".
In my own experience, I have found that just raw fruits or vegetables, eaten whole, are much harder to digest. Maybe the blending process somehow breaks down the fibers?
I developed stomach ulcer when I was like 19...
The symptoms indicated either IBD or IBS...
Unfortunately I still have a big problem with my weight. Because of this issue with bowels and then because of my transition to RAW paleo I became even more underweight – atm I am 56 kg ( around 120 pounds ) while being 186 centimeters tall, so it’s really skinny and depressing. I heard that people on this diet after some several months get back to normal weight, so I still have high hopes.
In any case, it is probably a good idea to restrict the amount of plant foods, especially if you have a history of ulcer and a lot of digestive problems. I used to suffer from IBS, gas, bloating, indigestion, etc. and what helped me immensely was carb restriction.
Another good thing to restore digestion is raw cream (if you tolerate dairy) - that will also help you gain weight!
