It's the simplest explanation that we have been underestimating just how unhealthy we are?
There's a synergy here, eat healthier, reduce blood sugar spikes, lose weight. And you are healthier than each individual effect alone would cause.
Maybe we're just ruining our bodies even if we don't put on weight by eating sugary foods that spoke our blood sugar. Or big meals that constantly make us switch into sit down and digest mode.
I'm open to something more happening but this isn't just GLPs. It seems we have uniquely attacked our bodies in a way that diabetes is the ultimate result but the entire journey is exquisitely toxic to our physiology.
Maybe fasting helps. Maybe keto helps. But this is similar to people who live off McDonalds suddenly go vegan and become healthy, is veganism that great? Or was the alternative for you just so awful for you?
