Prior to beginning a ketogenic diet you should undergo a health screening with your physician to confirm that a ketogenic diet is suitable for you and to rule out any conditions and contraindications that may pose risks or are incompatible with a ketogenic diet, including by way of example: conditions affecting the kidneys, liver or pancreas; muscular dystrophy; pregnancy; breast-feeding; being underweight; eating disorders; any health condition that requires a special diet [other conditions or contraindications]; hypoglycemia; or type 1 diabetes. A ketogenic diet may or may not be appropriate if you have type 2 diabetes, so you must consult with your physician if you have this condition. Anyone under the age of 18 should consult with their physician and their parents or legal guardian before beginning such a diet.

| 0:00.0 | Yeah, so metabolic switch is what happens when the energy in your liver, which is glucose |
| 0:04.3 | essentially, is depleted. |
| 0:06.4 | And then your body uses the fats and the ketones derived from the fats as energy source. |
| 0:10.1 | And typically it takes about, in humans, about 12 hours to deplete the liver glucose |
| 0:14.3 | stores and trigger the metabolic switch. |
| 0:16.1 | Now if you exercise, for example, if you eat less food at eight in the evening, then you |
| 0:19.3 | get up at seven in the morning and go for a run, the metabolic switch will occur early in your run and continue. |
| 0:24.7 | So the point is that exercise can accelerate the metabolic switch. |
| 0:28.5 | Welcome to the optimal protein podcast. I'm Vanessa Spina. |
| 0:34.6 | Hello, my friends. Welcome back to the optimalimal Protein Podcast. I am so honored that today we get to have the pleasure of having Dr. Mark Madsen joining us on the podcast. And we actually ended up midway through our conversation deciding to do another episode. So this is part one of two episodes |
| 0:56.9 | that will complete the full interview with Dr. Madsen. But in the first part of this episode, |
| 1:03.1 | we really got to talk a lot about the benefits of intermittent fasting, of ketosis, |
| 1:09.7 | and is there overlap between those different strategies what that overlap is |
| 1:14.5 | and then what are the benefits that you can get from just intermittent fasting in addition to |
| 1:20.9 | ketones and ketosis and we got to talk a lot about all of the different aspects of ketosis when that actually |
| 1:29.5 | begins, how long you need to be fasted before your ketones start going up, and a lot of detail |
| 1:35.1 | on autophagy and ketosis. And we finished up our conversation today talking a little bit about |
| 1:43.6 | brain-derived neurotrophic |
| 1:45.6 | factor and some of the brain benefits from intermittent fasting and then considerations for |
| 1:50.6 | women when it comes to intermittent fasting. |
| 1:52.3 | So part two, we're going to be talking a little bit more about some other aspects of |
| 1:57.6 | intermittent fasting and of Dr. Madsen's book including reactive oxygen species |
