This Destroys Your Metabolism… #drnickzyrowski

Here is what you need to know..

Fasting is a good things for you. But too much of it can slow the metabolism. This is why I recommend you practice intermittent fasting for only 5 days of the week and take a break 2 days.Chronically high cortisol has such a negative impact on your metabolism because of the stress and impact it has on thyroid function. To reduce stress I recommend doing deep breathing exercises like box breathing. I also like to use meditation and gratitude journaling as a way of stress reduction. As for under- eating… everyone should figure out their macros and calorie intake needed to have a ballpark figure as to what is required by their bodies. This way you are eating exactly what you need. Not too much, not too little.

Stay Healthy! Dr. ZPs.. you can use supplementation to drive down cortisol. If you are interested in what to use in my clinic, click here…
