In my personal experience, consuming a deficit below TDEE without concerning macros isn't enough to consistently achieve my weight loss goals.

I track everything using myfitnesspal and there's a strong correlation in my weightless during periods where I make an effort to consume around 30% of calories from protein. During less strict periods, my protein intake is usually around 20%. While my calories consumed remains the same, the higher protein diet is far more effective for weight/fatloss.
