I'm sure you've heard this before, but too much of anything isn't good for our health, L1teEmUp! The kidneys play a crucial role in how we metabolize and process protein, so significantly increasing protein will directly impact your kidneys and how hard they have to work to process this protein increase. Think of the kidneys as a muscle you're working out, when you increase the weight, your muscles need to work harder and require more to recover...when you increase protein, the kidneys need to work harder to filter out the waste that builds up from protein metabolism. Overtime, this can overwork the kidneys and lead to issues. You also have to remember, when you increase protein, the kidneys then need to step up their game to process the higher amounts, and this will impact their ability to do everyday tasks (aka the kidneys will become less efficient in their regular jobs because they're busy filtering out the extra protein). Something to keep in mind, while macros are based on specifics that I do not have (like your weight, goals, etc.), studies have shown that 1.6g of protein per kilogram (kg.) is the highest amount of protein shown to have any differences in building muscle. The changes in muscle mass when people consumed more than 1.6g of protein per kilogram (kg.) were insignificant.

This is a great question. I'd also like to know the answer.
