I’d sooner eat a high fat diet than even moderate carb or any kind of low fat diet.
Got diabetes in the family, I could lecture on how to manage it with diet (Type II), I’ve read so much research over the decades. Fat is crucial for stabilizing blood glucose.
For an introduction, read “The Zone” by Barry Sears (the 1994 book, nothing else called the Zone, the rest is marketing garbage). It explains (indirectly) why a high fat diet isn’t the Bad Thing we’ve been lead to believe.
