Summary

Dr. Jockers outlines seven common fasting mistakes that prevent autophagy and fat burning, including fatigue, cravings, constipation, and weight loss resistance. He provides actionable guidance on proper nutrition during eating windows, stress management, electrolyte balance, caffeine control, and gender-specific fasting protocols for women's menstrual cycles.

Insights
  • Protein intake of 30-50g per meal is critical for blood sugar stabilization, satiety, and successful fasting windows
  • Elevated cortisol during fasting is beneficial when balanced with growth hormone, but excess caffeine disrupts this balance and reduces fat burning
  • Women should adjust fasting windows based on menstrual cycle phases, with shorter fasts around ovulation and longer fasts during follicular phase
  • Stevia and artificial sweeteners can trigger insulin release and cravings despite containing no calories, undermining fasting benefits
  • Exercise timing relative to fasting windows significantly impacts recovery, cravings, and overall fasting adherence
Trends
Growing recognition of gender-specific nutrition and fasting protocols tailored to hormonal cyclesIncreased focus on electrolyte and micronutrient optimization during fasting periodsShift from calorie-restriction focus to hormonal balance and stress management for sustainable weight lossRising awareness of cortisol-growth hormone balance as key metric for fasting success beyond simple calorie deficitIntegration of functional nutrition coaching with personalized protocol customization becoming standard practice

Quotes
"When you're burning fat and you're producing ketones, that is a really great fuel source for the cells of your body. When you burn fat for fuel, fat produces a lot more cellular energy and a lot less metabolic waste in the body."
Dr. Jockers
"If you're not sleeping well, if you're stressed out, or if you are overdoing the caffeine, or doing stevia, things like that, you're gonna get more cortisol, low growth hormone, you're not gonna be able to burn fat well."
Dr. Jockers
"During your fasting window, no stevia, no sweeteners. You can do black coffee, but make sure that you're not overdoing the coffee."
Dr. Jockers
"When we're fasting, we get elevations in growth hormone, and that growth hormone is very anabolic, meaning that it helps preserve lean body tissue, and has very anti-aging characteristics to it."
Dr. Jockers
"The best time to fast for a female on your menstrual cycle is day one, when she starts menstruating, somewhere between day one and let's say day 10 to 12."

during your fasting window, no stevia, no sweeteners. You can do black coffee, but make sure that you're not overdoing the coffee. If you're noticing you feel agitated, more anxiety, maybe overdoing the caffeine. When you're fasting, you naturally have higher amounts of stress hormone, right? So when you're fasting, your cortisol comes up a little bit more than it would if you weren't fasting. And that's not necessarily a bad thing as long as it's balanced with human growth hormone.

When you do intermittent fasting, you really should feel great. As your body starts to burn fat, you produce ketones. Ketones reduce inflammation in the brain. They actually enhance mitochondrial function. You should feel very energized, mentally clear. You should be able to think sharply and quickly. Shouldn't have a lot of hunger and cravings, if any at all. You should feel really, really good while you're fasting. If you're not, you may be making some mistakes. And so here are the seven symptoms. One is fatigue. Again, like I said, when you're burning fat and you're producing ketones, that is a really great fuel source for the cells of your body. When you burn fat for fuel, fat produces a lot more cellular energy and a lot less metabolic waste in the body. And you produce ketones to get them up into the brain. And those ketones, they actually reduce inflammation in the brain. They're a great energy source for the brain cells. And so again, you should feel really good energized. If you're feeling fatigued, if you have brain fog, if you have dizziness, those are all signs that you may be making some mistakes when it comes to fasting. And we're gonna address those in today's training. Cravings, you shouldn't have cravings. Ketones naturally shut down cravings, so you shouldn't have that. If you are constipated, that's a little bit different. Obviously, if you're not moving your bowels, okay, you may not be hydrating well. You may not be getting enough electrolytes. You shouldn't be constipated when you're doing intermittent fasting. You should be able to actually move those bowels well. And then if you're not losing fat, let's say you're doing a 16 or 18 hour fast on a regular basis, and yet you just don't, you're not losing weight. You're not losing undesirable belly fat, right? There's a sign, that's a sign you may not be fasting correctly. So let's talk about what we need to do in order to fast properly. Well, the first thing is, when we look at our diet, we wanna make sure that when we eat food, we're eating somewhere between 30 to 50 grams of protein in each meal. That protein helps stabilize our blood sugar, helps stimulate the production of lean body mass, keeps our insulin levels down, and that's gonna reduce overall cravings and make us feel satiated between meals, and that gives us a longer ability to fast. We also wanna focus on getting good healthy fats. Healthy fats are gonna be things from, let's say, grass-fed animal products, wild-caught fish or wild-caught seafood, grass-fed butter, extra virgin olive oil, avocados, coconut oil, coconut fats, eggs. That's where we're gonna get our good fats. We want something between, let's say, 15 to 30 grams or so of healthy fats in a meal. We wanna make sure we're getting a lot of colorful fruits and vegetables when we consume our meals. We wanna make sure we're avoiding snacking. I want you to focus on eating two to three good quality meals with that protein level, 30 to 50 grams of protein in each of those meals. Okay, so if you're doing that, eating two or three times a day, 30 to 50 grams of protein, getting healthy fats, getting colorful fruits and vegetables in there, you're gonna be much more satiated, and you're not going to have as much cravings. One of the big mistakes I see people make is they just don't eat enough when they are eating, and they don't eat enough protein, especially. They really load up on a lot of starchy carbohydrates, a lot of carbohydrates that are very insulogenic that make your body produce a lot of insulin, and make you more insulin-resistant. And then it's harder to break into your fat stores because your insulin levels stay elevated. When insulin is elevated and you're not consuming food, that's gonna cause more cravings. It's gonna cause lower energy. It's gonna cause your blood sugar to drop a little too low, and you're not burning the fat for fuel, and so therefore you don't feel good, right? You have low energy cravings, like I said, you're gonna have a lot more issues. And so making sure you're really dialing in your food during your eating window is super key so you can have a successful fasting window. The other thing is making sure we're keeping stress under control and that we're sleeping well. That's super critical for keeping stress hormones under control. When we're under a lot of stress, if we're not sleeping well, our cortisol goes up, and cortisol is what we call a glucocorticoid, meaning it elevates blood glucose levels. When glucose goes up in our blood, insulin comes up, and then insulin will drag the glucose down and get it into the cells. Now blood glucose goes down, but insulin's still up, and now we end up with hypoglycemic-like responses where we don't feel good. We have brain fog, we have cravings, we have low energy, we don't feel good. And so that's another big issue, right? Making sure that, again, we're keeping our stress under control. We also wanna make sure that we're consuming enough electrolytes, particularly during our eating window, that we're consuming high-quality foods. They all have good electrolytes. You may need a little bit of electrolytes during your fasting window as well. And it could be as simple as taking a little bit of, let's say, good quality salt, Celtic sea salt, or something like that, Redmond's real salt, and putting it on your tongue, and just getting a little bit of sodium, a little bit of extra salt and minerals. For a lot of people, they notice that that gets rid of cravings, it gets rid of headaches that they may experience. If they're fasting, low energy, their energy goes up, they feel a lot better. For other people, they need an actual electrolyte powder, right, and so they'll put a little bit of electrolytes. For example, and some water and drink that, and that's really good.

What you gotta be careful of is, if you're over-consuming a sweetener like Stevia, or over-consuming caffeine, I see a lot of people, during their fasting window, they're drinking a lot of caffeine, like a lot of black coffee. In some cases, they're sweetening the coffee with Stevia, and that Stevia can trigger cravings, and actually trigger insulin release, which brings down your blood sugar and causes the hypoglycemic reactions. And so you wanna make sure you're, I recommend while you're fasting, during your fasting window, no Stevia, no sweeteners. You can do black coffee, but make sure that you're not overdoing the coffee. If you're noticing you feel agitated, more anxiety, maybe overdoing the caffeine. When you're fasting, you naturally have higher amounts of stress hormone, right? So when you're fasting, your cortisol comes up a little bit more than it would if you weren't fasting, and that's not necessarily a bad thing, as long as it's balanced with human growth hormone. So when we're fasting, we get elevations in growth hormone, and that growth hormone is very anabolic, meaning that it helps preserve lean body tissue, and has very anti-aging characteristics to it, helps support healthy collagen, whereas cortisol is catabolic, breaks down sugar, right? And if cortisol is not balanced by growth hormone, it will actually break down our skeletal muscle. So when we're fasting, we might have elevated cortisol, but we also have elevated growth hormone, and that balance helps us preserve lean body tissue, and feel great, because cortisol gives us a lot of wakefulness, and great mental energy. And so cortisol actually has a really great component to it, where it makes us feel great. We feel energized, excited, mentally sharp and alert, but if cortisol is elevated and growth hormone is low, now we end up breaking down muscle tissue, we end up over-agitated, not feeling good. And so for overdoing caffeine, we're gonna elevate cortisol more, and we're gonna reduce growth hormone. So if we take too much caffeine, we get too much cortisol, too much adrenaline, too much of these catecholamines, that break down tissue, and not enough growth hormone that protects the muscle tissue. That's not what we want. So keep your caffeine under control. Take the right dose that allows you to function really well, without having the unwanted symptoms associated with it. Also caffeine, too much caffeine can stimulate cravings as well, which can be an issue. So make sure you're keeping that under control. The constipation, you may not be hydrating enough, right? So making sure you're really well hydrated, okay? Making sure you're taking a good magnesium can really be helpful, and electrolytes in general. Making sure that we're doing that, super keeper, keeping things moving in your system. You shouldn't be constipated while you're doing an intermittent fast for let's say 16 or 18 hours. You should be able to move your bowels well, and that's actually gonna help you have a better fasting experience. So that's really critical. And then final, and really that balance between cortisol and growth hormone, like I was talking about, is super key for losing weight, losing belly fat. Because if you're not sleeping well, if you're stressed out, or if you are overdoing the caffeine, or doing stevia, things like that, you're gonna get more cortisol, low growth hormone, you're not gonna be able to burn fat well. Growth hormone will help trigger fat burning, and that's key, okay? And so these are the things that we wanna make sure we're doing. And then finally, if you're a female, let's say you're a female, you're in your menstrual cycle, another really important caveat is timing out your fasting. So the best time to fast for a female on your menstrual cycle is day one, when she starts menstruating, okay? Somewhere between day one and let's say day 10 to 12, great time to do intermittent fasting. Right around ovulation, ovulation is usually day 14. So right around that period of time, maybe a few days before, we want to do less fasting. You know, you might do an eight hour eating window during your first 10 days of your menstrual cycle, and then you go to a 10 hour eating window, or a 12 hour eating window, those few days right around ovulation, and then you can go right back to doing, let's say an eight hour eating window, right after that, up until the week before your menstrual cycle. So roughly day 20, day 21, somewhere in that on your menstrual cycle, that's when you go back into a longer eating window, a short fasting window, and that's also a great time to really consume more protein, more carbohydrate, just more calories in general, and tell the body, okay, I'm in a time of feasting, time of where food is plentiful, and that's gonna help your body, it's gonna help lower cortisol, and it's going to help with good progesterone function, progesterone release, so that way you have less PMS-like symptoms, and you have a really good healthy menstrual cycle. So again, the best time to fast for a female in our menstrual cycle is, you know, roughly the first 10 days or so, right after she starts menstruating, and then shortly after ovulation for several days, and then the week before menstruation in particular, that is the best time to do less fasting, and more eating, more feasting, okay, and also right around ovulation, okay, a few days before maybe, a great time to do less fasting and more feasting. So if you do those things, that's gonna help set you up for having a healthy fasting experience where you feel great. You don't have brain fog, you've got great energy, and you're able to really, really thrive in your life. One last caveat actually is exercise timing. I prefer exercising at the end of a fast. That's when I feel best. Exercise can oftentimes cause more cravings. You have to time it off of based on, you know, when you're able to do it, obviously, but for some individuals, they find that when they exercise, they need to eat shortly after. So try to time your fast around that as well. So if you're able to get, let's say, 14 hours in, 16 hours in before you exercise, that's great because you've gotten the benefits of the intermittent fast. Now you exercise, which further ramps up autophagy, and then you're able to consume food right after that, okay? It can be tough sometimes to exercise and then just wait a while, for, you know, let's say three, four hours before consuming food. Oftentimes you'll have more cravings, you won't feel as good if you do that, and you don't recover as well from your exercise. Some people do it and they feel great, but for a lot of people, they struggle with that. So that's something to keep in mind as well as your exercise timing. So hopefully, I know there's a lot of information here. Hopefully you guys got a lot out of this and we'll see you in a future training. Be blessed. Well, that's all for this show.
