Starting on a New Diet

The other day I started trying to practice a calorie restriction (CR) diet. The point of this is not to lose weight (I'm not currently overweight or not by much anyway), but to increase one's likely longevity and overall state of health by keeping fasting blood glucose levels low. Too soon to see results (I haven't gotten a glucose meter yet), but the striking thing is how different the same physical sensation can seem depending on one's attitude toward it. Previously hunger would tend to make me anxious, based on a supposition that it's evidence of a condition threatening to my well-being. But now that I understand moderate hunger is actually a sign of a healthful condition, it rarely disturbs me at all.
