You are currently downvoted but I think there is something to homeostasis.
My favorite counter point to calories in/out crowd is that the body is a dynamic system. The calories out portion doesn't stay constant. I have lost weight while eating more because my base metabolism increased. In "That Sugar Film," the guy eats the same amount of calories and same activity level but starts to include "daily recommended sugar" and increased his weight. The body is a dynamic system and will change how it stores and processes energy. Yes, you can't violate thermodynamics and eating a calorie deficit will cause weight loss (and possibly other issues), but the system tries to adapt.
