Here is what I know about calories:

There are four types carbs, protein, fat and alchohal

Carbs- contain 3.75 calories per gram- when choosing what carbs to eat you should choose one that are low on the glycemic index also known as complex carbs not sugar carbs.

Protein-contains 4 calories per gram similar to carbs. This is relatively self explanatory. You should be eating plenty of this!! Duh winning!!

Fat- contains 9 calories per gram. Yes that's right over double protein and carbs. The only fat you are going to need to worry about obtaining is omega 3 fatty acid. You get it from flax seed and oily fish.

Alcohol- 7 calories per gram. If your cycling don't drink!

Calories are all the same? Yes they all burn at the same rate that's what a calorie measures. But some calories are more easily converted into fat than others. And any excess calories will be stored. This is why the exact food log is necessary to see how your body reacts to your daily routine and diet combined. Or in other wards figure out the rate of you metabolism.

Keep in mind you said you want to bulk. For some bulking and staying slim is an oxymoron.
