- eat a little protein and lots of fructose from an apple from your garden;

- eat the same amount of calories as proteins + fat in industrial meat.

The second amount will create vastly more waste, such as urea, to be processed by the body. It will also require more energy to processed because the fructose is almost usable as-is. Because the second source of calories brings less minerals, it will also bring your PH down, forcing the body to deal with it. Because it's industrial meat, it will contains synthetic products such as antibiotic than will make your livers works a lot more and impact your digestive system flora.

But will not trigger the same insulin response.

Same amount of calories, very different context, and impact on the body.

Again, I notice a trend in those responses: you are just saying I'm wrong harshly but don't make demonstrations. If you know I'm wrong, please use arguments.
