Summary
For years we've been told that if fasting is good, then fasting longer must be better.
That simply isn't true.
Fasting is one of the most powerful healing tools we have, but it's also a stressor. Like exercise, the benefits don't come from the stress itself. They come from how well your body recovers afterward.
In this solo episode, Dr. Mindy explains how to tell whether fasting is supporting your metabolism or pushing your nervous system beyond its limits. You'll learn the five green lights that signal your body is adapting well, the five red flags that tell you it's time to pull back, and simple ways to adjust your fasting practice based on your hormones, stress levels, and stage of life.
Whether you're new to fasting or you've been doing it for years, this episode will help you stop guessing and start working with your body instead of against it.
In this episode you'll learn:
- Why fasting is a beneficial stressor, but only in the right dose
- The difference between metabolic stress and chronic stress
- How your nervous system influences your fasting results
- Five signs fasting is working with your body
- Five red flags that indicate your fasting routine needs to change
- Why sleep, energy, hormones, and muscle are powerful feedback systems
- How to adjust your fasting practice based on your cycle and life stage
- The importance of recovery, refeeding, and metabolic flexibility
- Why fasting should always be personalized

| 0:00.0 | Hey, Dr. Mindy here and welcome to the Live Like a Girl podcast, where I bring you icons, disruptors, educators, scientists, and doctors that show you what can be possible when you love and celebrate the female body you are blessed to live in. Let's dive in. One in three adults are |
| 0:26.2 | completely overwhelmed with their stress loads. Looking at it through that picture, fasting might not |
| 0:34.3 | be the best tool for a completely stressed out human. It doesn't mean fasting doesn't |
| 0:41.1 | work. It means that once again we need to think about if fasting is right for you. So in this video, |
| 0:50.5 | I am going to walk you through five signals that your body will give you to tell you |
| 0:57.2 | if fasting is working or if fasting is not working. I call them green lights and red lights. |
| 1:04.7 | And I'm going to show you five action steps you can do to either modify your fast, stopping your fast, or do more fasting |
| 1:14.6 | depending on where your stress loads are at and how your nervous system is handling it. |
| 1:21.6 | This is a video we've needed to do for you for a very long time, and I can't wait to dive into this. |
| 1:29.4 | So here we go. Let's go. First, we have to say, just like exercise, fasting is a stressor. |
| 1:37.5 | So that's not a secret. Hopefully you understand that it is a hormetic stressor. |
| 1:48.1 | Hormesis is a good stressor. This is how fasting works, is that it applies just a little bit of stress on the system that causes your |
| 1:56.8 | body to grow bigger and do better things, just like exercise. When you go and exercise, |
| 2:03.8 | if you are lifting weights, you break muscle down and that muscle is under stress, but it builds |
| 2:11.9 | itself strong again. That's the same thing that's happening with fasting. But it's if you think about it, |
| 2:19.6 | it's when we're already in a broken down overwhelmed state. If we put more fasting on top of that, |
| 2:27.7 | that's not a good system. The stress that we put ourselves in, whether we fast, whether we exercise, whether we cold plunge |
| 2:38.2 | or sauna, that is a signal, but it's in the aftermath of that, in the recovery where the |
| 2:45.5 | magic starts to hit. |
| 2:48.1 | So think of it like your metabolic switch. Remember how I taught you about the metabolic switch? |
| 2:54.5 | You could, when you eat you're a sugar burner, there's no stress there unless you're eating the |
| 2:59.1 | wrong food, like ultra-process foods. But then when you switch over into fat burner, this is called |
