I did not care for intermittent fasting after trying it twice for a short time.
I understand the hormonal response it is supposed to trigger, but eating that much food at once - especially bodybuilding amounts - has got to lead to insulin spikes.
Insulin is a "storage" hormone, and I fail to see how one can optimize fat loss with those spikes.
It seems that keeping insulin levels steady with smaller frequent feedings is the way to go when keeping body fat in check.
Just don't eat carbs. Different foods trigger insulin response at different levels. Carbs trigger high insulin response to fat storage levels. Proteins only trigger insulin response to way less than half what carbs do. And animal source fats hardly trigger any insulin response at all. Plant based fats and proteins, seem to trigger high fat storage insulin response, as though the body knows that they come from plants.
We didn't evolve to eat carbs. We only started doing it in the last 10,000 years or so. It wasn't a good move health wise. Eating massive amounts of carbs has only gotten worse in that last 50 years, coinciding perfectly with the increase in Type II Diabetes, and gross obesity.
Check out the Woodstock documentary, 1969. Today, everywhere I go there are huge fat slobs all over the place. You don't have to seek them out, they are literally all over. But in the film of Woodstock, it's hard to find even one fat slob. That's because 1969 was before High Fructose Corn Syrup, and all the garbage plant based proteins and oils (fats).
And check out the Jimi Hendrix and Janice Joplin performances too!
