Calories vs macros

Calories are a unit of energy...weight management is about energy management...when you take in more energy than you require to maintain the status quot, that excess energy is stored as body fat (energy reserves). When you consume less energy than you require, you burn your energy reserves (body fat) to make up for that deficiency.

It's calories. Macros don't really have anything to do with weight loss...they have more to do with general nutrition and balancing out your diet and can impact fitness performance and will effect overall body composition.

Both matter, calories are more important. You can lose weight while ignoring macros, but not by ignoring calories. Macros do help however, and some of the ways of managing macros can make it easier to manage calories than pure counting depending on how you take to them. Generally, this:

Yes, you can lose all of it with just calories alone. I have lost almost 30 lbs changing my macros around it seems like almost every week because I couldn't stick to anything except a deficit (I tried low carb, high carb, high protein, etc...) and without consistently working out. I am now in the normal BMI range with only 10 or 15 more lbs to lose. Now, I am following a plan (StrongCurves), and really paying attention to my macros because I know it is more important now for my aesthetics to pay more attention now.

You can certainly pay attention to fitness and macros earlier in your journey (it may benefit you more). But there is nothing wrong with just following a deficit.
