Macro splits

I've been trying to understand a little more about the importance of macro splits and wondered whether any clued up ladies can assist.

I understand the protein element, and the benefit/impact that has on the body. However, how about the fat & carb ratios? How do they impact you?

Is it important to stick to certain ratios of carbs & fat, or is some flexibility ok as long as you're on track with total calories?


In my case, per the TDEE calculator, I'm aiming for 1500 calories a day, and I've opted for a 40 / 40 /20 split (20 being carbs). That equates 151g protein / 67g fat / 75g carbs.

In a typical week, I'm actually averaging around 1200-1400 calories, and am over on carbs (85g), protein is under (100g), and fat takes the rest (75g). This ends up being a 30p / 40f / 30c split.

Ultimately, I'm losing weight at 2lbs per week, so what I'm doing is working, but I'm the kind of person that really needs to understand things properly.

Protein intake is also a bit of an issue at the moment, but I'll post separately about that.

Thanks in advance!!
