A Note From My Experience

I used to obsess over calories. I counted everything. It made me miserable. Here's what I learned: calories matter, but they're not everything. Focus on eating real food. Stop when you're full. Drink water. Don't starve yourself. And please, don't let a number ruin your day. Use this as a guide, not a rule.
