Cortisol: Our brains don't know if we're stress or low in sugar
I usually spend my second visit teaching this stuff to every patient because once they start eating adequate protein every 4 hours most of the symptoms mentioned above completely go away. It’s often the main cause of headaches, anxiety, nausea and sugar/carb cravings in most of my patients.

Healthy weight loss without intermittent fasting
There are some populations who might benefit from IF but anyone considering it should be sure to work with a professional to guide them through it. There are a lot of important details that must be accounted for, in order to benefit. Intermittent fasting can be very effective or very detrimental. This article is intended to shine light on the possible pitfalls of intermittent fasting so it is used responsibly, I don't mean to totally discount it as an effective treatment for weight loss. There are so many factors (personal health, frequency, duration, exercise, etc...), that I don't think it is a safe thing to do on your own without being properly assessed and guided.
Be sure to comment below, I’d like to hear your stories, opinions, etc… It’s a great thing to discuss right now.
