I've been told I need to eat every 3 hours for muscle building. Can I build muscle while fasting?

I broke my fast by accident — had a sip of milk in my coffee. Do I need to start over or is it fine?

I get incredibly hungry at exactly 11am every day even though I'm eating a big dinner at 7pm. Any tips?

I'm a nurse doing 12-hour shifts. How do I fit fasting around a schedule that changes every week?

Can I have a small handful of nuts during my fast if I'm really struggling? Will it ruin everything?

My sleep is much worse since I started fasting — I wake up at 3am every night. What's going on?
