So I've got a history of kidney stones and I'm trying to figure out how much protein I can actually handle without risking another trip to the ER. I see all these protein targets thrown around like 1.5 to 2g per kg, but is there a real limit for someone like me? Anyone got the facts or just more trendy bullshit?

  If you're worried about kidney stones, maybe try a mix of plant-based proteins. I found that less animal protein made a difference for me. Smoothies with spinach and protein powder could be a tasty option too, and you won't miss out on nutrients. Just keep sipping on that water!

  I totally get your concerns! I had a similar issue with kidney stones a few years ago. My doctor said to keep my protein around 0.8g per kg, especially since I love my chicken and beans. It's tough to balance, but staying hydrated really helps. Have you tried tracking your intake with something like MyFitnessPal? It's super useful for keeping an eye on protein levels without overdoing it.

    Bro, just stick to whole foods and you're golden. You don't need to stress over trendy protein shakes or whatever. Eggs, chicken, lentils, load up on those. Keep it simple, man.

      Yeah, I don't buy all these 2g per kg claims. Just eat what feels right. If u're getting kidney stones, maybe drop the protein a bit and focus on hydration. Facts.

  When it comes to protein intake, especially for someone with your history, I'd stick to around 1-1.2g per kg. A study I read mentioned that higher protein diets can be a risk for kidney stones in some people. Keeping your hydration levels high is crucial too, as it dilutes the minerals that can form stones. Tracking macros is easier with apps like Cronometer since they break down minerals as well.

    Just to throw some science at this, research shows that excessive protein can lead to higher calcium excretion, which might increase stone risk. i stick to about 1g per kg, and im running 6 times a week! Keeping that balance is critical. Also, you could consider consulting a registered dietitian if you want a personalized plan.

    You might want to look at your calcium intake too, it plays a role in stone formation. I know it sounds crazy, but balancing calcium with protein can help prevent those painful visits to the ER. I went through the same struggle and found that keeping a food diary helped spot patterns. Use something like MacroFactor for tracking, it's solid.

  Honestly, I've been there too. Tried pushing my protein after lifting, ended up in the ER with stones. Now I just keep it chill, like 1g per kg max. It's not worth the pain! And drinking enough water is key, otherwise, you're just asking for trouble.
