Macro Ratio: Per Meal
No matter what kind of diet you do; intermittent, 3 hour, 6 hour, Vegan, Paleo, IIFYM, Keto, Meal plan, etc you MUST meet your daily goal. The major point that will lead you to succeed or fail in your fitness goal is what your eating v.s. what you burn. If you want to lose weight your goal is to burn more than you eat. On the other hand, if your goal is to gain muscle then you want to eat more than you burn. There are also macro nutrients (you can read more on what a macro is here) that are important to meet.
Now, if you want to reach a goal of elite body fat, usually for a competition, than yes it is important to look at your meal timing and how many macros you eat for each meal. This doesn't mean that you shouldn't be looking at this even if you just want to lose a couple lbs, what it DOES mean is that it is not as important as just hitting your caloric and macro goals daily.
Here is an example of what a typical day for me looks like in regards to meal per ratio:
Meal 1: ( PRE- WORKOUT)
6G Fat/ 41G Carbs/ 27G Protein
Meal 2: (POST-WORKOUT)
6G Fat/ 48G Carbs/ 35G Protein
13G Fat/ 40G Carbs/ 40G Protein
15G Fat/ 28G Carbs/ 28G Carbs
13G Fat/ 28G Carbs/ 30G Protein
My goals right now is to gain muscle so I am in a caloric surplus. I try to keep most of my carbs before and after my training. When my carbs are high I try to keep my fats lower and vice versa.
