If body composition is important for performance, and you believe “calories in / calories out” is obsolete, what methodologies should we use?

Calories matter, but what matters more is the hormonal effect of those calories. Some calories cause your body to release hormones that make you store fat, while others like testosterone can help you build muscle. To get control of your hormones, you should look at what the calories you are eating are doing to your hormonal universe, particularly insulin which is the fat storage hormone. Cutting back on carbohydrates is a good way to start seeing results in terms of losing body fat within a week.
 
Transcript: "So, whoever asked this question, I love you for asking it, because I have a feeling that anyone who's heard me talk about calories. Probably has a similar question. So, here's what the question says, if body composition is important for performance. Yes, it is. And you meaning me believe the calories in calories out is obsolete, but what methodologies should we use? So I want to explain what I mean, when I say the calories in calories out is obsolete, I don't mean calories or obsolete. That they don't matter. But for decades the traditional way of looking at changing your body composition is to do a math test and see if the calories in a equaling or greater than the calories out. And is if the human body behaved like a checking account, you take this much in you spend this much. What's left, is he the muscle and fat? That's what's obsolete. It's not that calories, don't matter. It's that they can't take center stage and you can't ignore Nor the hormonal effect of those calories because some calories, tell you about a to release hormones that make you store fat and some calories. Don't some hormones like testosterone, tell you to build muscle, so you got to get control of the hormones. Now, how do you know, it's not as easy as just doing the math but it's more effective. First of all, you don't have to throw out the math equation. I do that from time to time, I keep track of my basal metabolic rate and I think about how much I've gone over or under, it's not that you can't use that. But what you got to look at it, What are those calories doing to your hormonal universe? And that's what's telling you to gain or lose. So if you see yourself gaining more body fat than you want, or your stomach is expanding, their likely culprit. Is that the calories that are coming from fat, from, I'm sorry from sugar and from starch, are the ones that are triggering that storage of fat. It's likely to be that and simply cutting back on those carbohydrates. Should immediately give you a result within a week that you can see. So That's that's my answer calories matter. But what matters as much or more is what those calories do to your hormones? Namely insulin, the fat storage hormone and if those calories that you eating are triggering a lot of insulin, it's going to be impossibly difficult to lose body fat, and continue to gain muscle."
