I went gluten free (which is VERY EASY - DO NOT buy any ‘gluten free’ products they taste like sh*t - except for some cheese snacks)
Cutting out all wheat made a WORLD of difference. My joints stopped hurting, I no longer have severe heartburn, and my stomach deflated like a balloon.
Then I kind of evolved into a paleo/keto/Mediterranean diet. I lost a good 30 pounds and feel so much better.
If you don’t want to memorize all the rules, just stick to MEAT and VEGGIES for a month.
See if it works for you.
Good advice
Dropped 86 pounds going to keto diet. Back to my college running weight.
