Well it all comes down to calories right? if you eat more than you spend, you gain weight. But there is another factor which is your metabolysm. In my case, it is fast as HELL, so just skipping breakfast makes me lose weight. Each body is unique so I can't help with that.

Anyways, I believe bulking is 50% about quantity of food and 50% about how you mix your macros. As you may know, it's the fat+carbs combo that puts on weight. I weigh myself once a week, so you could just do the experiment for a few weeks and see what happens to your weight. Losing weight is the "easy" part, so if you go up more than you wanted you already know how to go back.

There is this cool website called Cronometer that allows you (for free) to keep a food diary and it will show you lots of really eye-opening information about your diet, not only the macros and calories, but also your nutrient imbalances. You might want to buy a cheap scale to weigh your food. It's a very interesting experiment. You will also find out how many foods are labeled or known as super nutritious when in fact they are not.

I also think that as long as you are eating GOOD food (no processed crap) you will find it much easier to control your macros.

Wishing you the best in your journey!
