macro nutrients

I think so.

not to lose weight no (just need deficit) but if you want to improve your body composition and make sure you are losing fat rather than muscle, than yes,

macros make or break you.

yeah you`ll lose weigt in a deficit...but I have seen that having negative impacts wayyyy too many times. like this one dude who wouldn't take carbs and ended raging wars every time in the bathroom......i`d rather count macros.

yes.

macronutrients are needed for proper nutrition.

you need fats for all sorts of functions in the body (e.g. skin and hair health, brain health, blood clotting, etc.) as well as to aid in the absorption of certain vitamins.

you need protein to help retain muscle mass while eating at a significant caloric deficit.

set your daily MINIMUM goals using these guidelines (ignore the MFP defaults and % ratio approach).

1) protein (in grams) = 1g/lb of LBM. LBM is lean body mass. LBM = (1 - BF%) x bodyweight
2) fats (in grams) = 0.35g/lb of bodyweight

whatever is not protein or fats in your dietary intake is necessarily carbs. i personally don't track carbs.

once you know your daily minimums, try to reach or exceed those amounts within the calories you eat that day (or on most days).

my goal is to lose weight and get lean and fit like Eminem,david beckham or adam levine..i dont wanna pack much muscles ..I keep my carbs 190-210 protein 50-70 and fat 40-60. is it good enough?

i don't know your bodyweight, but your protein and fats seem low. run the numbers yourself with the equations i gave you.

"lean" is simply a function of bodyfat % (BF%). however, "lean and fit" implies some amount of muscle development. you can get that without getting huge, but you also need to retain what muscle you have while on a significant calorie deficit. it's hard to say what number that is for each person, but at a certain calorie deficit, your body will run out of ready energy (glycogen stores) and will not be able to get the necessary extra energy fully from fat reserves, and it will also begin to catabolize muscle proteins to meet its energy needs. that's what you want to avoid and that's why dietary protein intake is important. it's a bit of an insurance policy to help minimize muscle catabolism (along with regular strength training while on a deficit).

to get the body you want, you should eat at a calorie deficit, do cardio to allow for enough extra calories to satisfy your appetite, make sure to eat a balanced diet and/or take a good multivitamin daily, strength train 3-4 times a week to the point of muscle failure (you won't gain much - if any - muscle mass while on a calorie deficit), and track your protein and fats macros to ensure that you're getting enough. stick with it and you should get the look you want without too much trouble.
