Hey, nice post, but you shouldn't be worried just about calories if you're trying to lose weight. Protein, carbohydrates and fats are very important. Carbs are energy and if you don't spend that energy before going to sleep, it is going straight to your belly. It is important to consume carbs before training and only little after training. You can eat more carbs if you are feeling really exhausted, that depends. After training, I suggest eating only protein and small doses of healthy unsaturated fats. And be in a caloric deficit of course. I usually calculate my caloric deficit by this formula: your weight in pounds times 10. So my caloric deficit is 182 * 10 = 1820 calories per day. I am not saying you have to use my formula, it is for moderately fast weight loss, if that is not your thing you can add or remove some calories. Hope that helps.
