Truthfully, I think society has been holding on to the '50s standard of "balanced diet" for WAY too long. I mean, those standards (or "nutrition guides") were developed coming out of the shortages from WWII - of everything... quality meats, produce, fruits etc. So the "balanced" diet is based on 1950s data, thinking, research at the time. Additionally, a 'one-size-fits-all' approach is flawed in pretty much everything. What works for you, for me, for Greg, for Kade ... it's all unique.
I'd very much like to try a keto diet, but no one else in my house will, so I'm not going thru the effort for just myself. I just try to keep my cals in check, and take in as much protein as I can. I could be much cleaner on my diet, and at some point, I will clamp down so that I can shed some of the body fat that I want to, in order to get to 10%-ish BF before I turn 50.
