I think what @BrickHead is saying, and I agree, is if you’re NOT prepping and just trying to lean out some, macro ratios aren’t as vital. If you’re in a prep, macros matter big time. Each individual is different and it takes time and constinency to find what works best for you in terms of ratio. It’s not like if you’re leaner macros matter “more,” if you’re trying to just lose some fat focus on calories most importantly and keep macros in check. But in a prep macros should be meticulous.
Even not on a contest prep, some people might lose weight more with lower carbs if they are more insulin sensitive, some people can still keep a lot of carbs with a higher glycemic index and lose weight. So even if you’re just trying to lean out macros may not have to be as meticulous but you should still roughly be aware of how many protein, fat, carbs are getting and what your body tolerates well to get the best results.
