Could be fructose intolerance. There's a lot of paleo foods that could be triggering it ( most fruits except bananas, coconut and tomatos all have fructose)and that could be why you can't pinpoint one thing. I have a friend that is fructose intolerant and she bloates to the point of looking pregnant as well.

I highly recommend going Terry Wahls. I know, it sounds very restrictive, but it might really help. Try it for three days - I saw the difference in one day.

And avoiding all fruit if you need too. Also, have you tried probiotics? They might help or might cause intestinal distress - it is different for everyone.

My gut feeling - you have been doing Paleo 75%, but you might be gluten intolerant 100%. The issue can be gluten intolerance and Terry Wahls diet will take care of it.

Good luck, don't give up!

Agree with Melissa.

If you have been exposing yourself to gluten repeatedly, then it's likely that your gut flora is messed up and you have developed FODMAPS intolerance.

I eat closer to 90% Paleo now. Here is one day of my food journal that I marked down feeling super bloated that evening: Applegate turkey sausage & black tea for breakfast. Walnut/Macadamia nut mix snack Chicken deli meat & paleo meatballs, boiled egg, guacamole, and raw veggies for lunch. Spoon of almond butter and a few carrots for snack. Green salad, 2 cucumber wrapped sushi rolls (no rice), and red wine for dinner. I own a fitness studio and workout at least 2 times a day (crossfit and then instructing a group fitness class) so I find myself hungry quite often.

Avocados absolutely kill me.
