This is part two of the interview that I had the pleasure of getting to do with Dr. Mark Madsen.

Metabolic switch is what happens when the energy in your liver, which is glucose essentially, is depleted.

And then your body uses the fats and the ketones derived from the fats as energy source.

And typically it takes about, in humans, about 12 hours to deplete,

deliver glucose stores and trigger the metabolic switch. Now, if you exercise, for example,

if you eat your last food at eight in the evening, then you get up at seven in the morning and

go for a run. The metabolic switch will occur early in your run and continue. So the point is

that exercise can accelerate

the metabolic switch. Welcome to the optimal protein podcast. I'm Vanessa Spina. Hello, my friends,

welcome back to the optimal protein podcast. I am your host, Vanessa Spina. And I am so excited for

this episode. This is part two of the interview that I had the pleasure of getting to do

with Dr. Mark Madsen. He is a neuroscientist at John Hopkins, and he has done and authored

some of the most extensive research when it comes to intermittent fasting, ketosis, ketones,

and the various effects on our physiology, on our brain, and so much more. And he just wrote a book called

the Intermittent Fasting Revolution. And on this part of the episode, we get to talk

specifically a little bit more about combining exercise with intermittent fasting. How long

should you be fasted to do your exercise and sort of maximize the benefits that you get from that?

We really talk about the benefits of doing

physical activity and intermittent fasting on the brain, on the body, which we covered a little bit

in part one, but we go into it more into detail in terms of maximizing those benefits. We talk

about hormesis and this concept of hormesis and how a little bit of poison can help, you know, a little bit of poison can help,

you know, this sort of low grade stress can help ourselves to become stronger and
