Fasting feels easy today

Long time lurker, first time poster. I don't have anyone IRL to tell, but I'm really proud of myself that it's 4 p.m. and I haven't eaten a single thing. I'm not even remotely hungry or lethargic. I feel amazing. I feel like I could go the entire day or week without a drop of food. Oh, and I also did a 25-minute high-intensity cardio workout this morning. How long are you all able to fast for?
