Carb/protein/fat daily percentage for weight loss?

If you put your demographic stats into your MFP profile, MFP will recommend a very mainstream starting point for calorie intake and amount of each macro.

That's easy, and it leaves few excuses for not starting immediately. Having to research every detail before starting can be an excuse, for some - not saying that's true for you.

As you proceed, you can learn more, and make changes to any of calories or macros. If you know enough now, make them now. If you don't, the default percents aren't a bad starting point for most people. The exception would be people who try to lose weight too aggressively fast for their current size. There's no getting adequate nutrition on too few calories.

Because of that, I'd suggest telling MFP you want to lose a number of pounds or kilos that's no more than .5-1% of your current weight, with a bias toward the lower end of that range unless you're severely obese and under close medical supervision for deficiencies or complications.

In USA terms, you're about 5'11, and weigh about 220 pounds; your 85 kilo goal would be 187 pounds. Your MFP profile says you're male.

One kilo loss per week may be sustainable for a while at your current weight, but if around 20 kilos are the total amount you have to lose, it could be a little aggressive for best odds of preserving of existing muscle mass, especially if you stick with that loss rate the whole way. Your call.

If weight loss is the key goal, calories are the direct determinant. Nutrition (macros and more) is important for health, but it's impact on body weight is indirect, usually through fatigue (move less) or spiked appetite (urge to eat more). Calories are still the direct mechanism.

Tom is right: Treat your starting calorie goal as a hypothesis to test. Follow it pretty closely on average for 4-6 weeks, like +/- 50 calories-ish. At the end of that time, compare your average weekly weight loss to your goal, and adjust calorie goal if necessary. Calorie recommendations from MFP or any other source, including fitness trackers, are just statistical estimates, basically the average for demographically similar people. You're an individual. Most people are close to average, but a few will be far enough off from average to make a meaningful difference, either high or low.

I'd recommend working first on figuring out how to stay reasonably full and happy most of the time on the reduced calories so you can stick with it, if weight loss is the main goal. If you can't stick with it, you won't get to goal. Time enough to tune up nutrition once that's dialed in, though you may notice that getting relatively more protein, fat or fiber may help you feel more full more often. (People vary in which if any of those matter for feeling full.)

When it comes to nutrition, realize that protein and fats contain "essential nutrients" that our bodies can't manufacture on their own out of anything else, so we need to eat a certain minimum. I'd suggest focusing on those first. Protein is probably number one during weight loss, so that we keep as much as possible of existing muscle. Retro's suggestion of 0.8g per pound of goal weight daily is sensible as a rule of thumb . . . whether lifting or not, IMO. (But lifting is a good plan.) Obviously, 0.8g per pound is 1.76g per kilo.

If you want a more nuanced but research-based protein estimate, consider this source:

You can use your goal weight in the calculator there.

For fats, I go with 0.35-0.45g per pound minimum daily, but I'm female. Men might get away with a little bit less, maybe 0.30, but that's not my wheelhouse. As you know, 0.35-0.45g per pound would be roughly 0.8-1g per kilo.

Carbs are more flexible, not "essential nutrients" in the same technical sense as protein and fats, because (loosely speaking) our bodies can manufacture carb equivalents on their own.

It's fine to go over protein or fat minimums, within reason. Being persistently and significantly under either one is not the best health strategy. The limit when going over the minimums is basically avoiding eating too many calories, or getting too little nutrition.

My bias is to augment the protein and fat minimums with lots of varied, colorful veggies and fruits for micronutrients and fiber. I strive for at least 400g and more like 800g daily as a minimum. Not everyone will agree . . . and those tend to bring in some carbs, though nutrient-dense ones.

Repeating myself, though: Nutrition is about health, energy level, body composition and that sort of thing. It's the calories that matter most for weight management.

Best wishes!
