FYI: it's not bred per se, it's how commercial bread is processed. First there is Roundup in the wheat, second they add 3x the gluten & rise the bread for 15-30 mins., this doesn't give the yeast the time it needs to break down the gluten sufficiently to not cause problems in the digestive tract. Each person has a different tipping point. Long & short of it, if you think bread is making you gain weight, try making your own. The best weight loss comes from eating whole, real foods, healthy gut biome (think fermented foods), meditation/yoga/prayer, fun exercise. Each stage of life and any medical conditions have their own needs to deal with. There is a really good online course through Coursera on Pain & Lifestyle taught by Dr Frickton at the U of M.
I keep chicken as part of my meditation, it just backfired for me. I worry about them regularly.
