Should we strive for EACH meal to meet our goal ratios?

Nah, it isn't worth it. It makes meal planning a real challenge. The benefits are vague at best since foods are digested at different rates depending not just on the food itself but on the acute metabolic needs at any given time.

Like you, I log everything to the nth degree. However, if I weren't doing that and only casually following LCHF then balancing macros across meals might be an easy way to keep an eye on things.

Protein *might* be worth balancing across meals, at least casually, because there is an upper limit to how much protein can be processed by the body for LBM use and there is no storage mechanism for it so it either gets used for LBM, turned to sugar and used as an energy source or excreted. But even that statement, which is accurate to my knowledge, is contrary to the evidence produced by IF (intermittent fasting). If protein *had* to be balanced throughout the day then IF'rs would all turn to jelly because they'd be losing LBM left and right. As far as I know, IF does not result in loss of LBM if calories and protein is in the right range even when eaten mostly in one meal.

Dairy fat can be an issue for some people. The only way to know for sure is to test and accumulate data. The dang thing is, your body is not static. So, you may have different results after a few months.

By the way, it takes time to become keto-adapted with NK's moderate protein regimen so the time to experiment based on BK readings is after you've done a month or so of NK from my experience with other people's posts that test BK (since I do not test myself).

One thing to be very careful of is getting stuck on macro percentages. They are meaningless. If you eat 80/15/5 today, how many grams of protein did you eat? 20? 100? See? Since they are a ratio they don't tell you anything without the context of calories. All they do is hide bad macro grams. Eat your protein grams to goal, keep your calories where you want and let the macro percentages fall where they may. They are an interesting after the fact datum but other than flagging an acute macro issue as you log your meals they don't do much for you.

Unless you set your calorie goal based on those percentages. For example, if my protein goal is 100g that is 400 calories. If my macro percentage goal is 80/15/5 then my calorie goal has to be 2700. 400 calories from protein is 15% of 2700 calories.

Your protein goal is 65g which is about 260 calories. So your calorie goal would be established at 1700 to make 80/15/5 your macro percentage goal - 1700*.15 = 255.

Just as an aside, I used to run a popular 80/15/5 NK thread on a different forum. We'd get 30,000+ views every month and we had a lot of fun. When I started that monthly thread I used 80/15/5 in the title because I wanted to set it apart from the competing low fat low calorie (and, truly, stupid) approach to NK thread. I kept 80/15/5 in the title even after I realized that macro percentages were a blind alley because 1) I was stubborn; and 2) I wanted to emphasize the high fat nature of NK; and 3) as an ode to the origin of the thread; and 4) to tweak the low cal trolls from the competing thread. But, man, I had to battle my own thread title all the time lol. Lots of new people would read the title and only skim the intro where I clearly stated that macro percentages were nominal and not the goal.

Anyway, if 80/15/5 happens to align with your calorie and protein goals then that is great. If not, then throw 80/15/5 overboard because the important thing is your protein grams and relative calorie deficit and most of the time that won't result in an 80/15/5 percentage.
