Since you still workout on fasting day, does that mean it’s ok to eat nothing after your workout? I’m considering the Monday/Thursday fast but I do CrossFit. Hard to imagine a brutal workout and then eat nothing.
It took our bodies a good six weeks to get used to fasting. You will absolutely feel hungry! But the human body is designed to burn fat for fuel, not breakdown muscle. That said, as athletes it is important for us to pay attention to our bodies. If you feel light headed or dizzy – eat!
You might have to move your one meal on fasting days to a different time. For us, evenings work well. For you, maybe it’s breakfast or lunch. Play with it and see what makes you feel best.
Also, Dr Jason Fung is a great resource about fasting.
