Just making sure that I'm clear, I'm not anorexic at all but I have lost about 20 pounds (mostly from cycling, 210-190lbs). Now, I'm feeling pretty good and healthy but once I've gotten to 190 and plateaued out, I've been eating very little lately (it have coincided with my running out of money so I had to eat less anyway). Eating less is usually no problem for me since I've always ate too much at most meals in the first place but in the last week, I've only had 1 meal a day (2 meal a day yesterday and today so far). I do drinks a whole lot of water but I still worries that I'm getting too close to eating too little.
So here is my question, How can I spot any under eating issue? are there some kind of usual symptoms that I can check for in the future?
