The issue with n=1s is that they can always be contradicted. For example, I'm almost the opposite of you.
I'm male. I'm 5'9" and weigh 118-120 lbs. I eat mostly bread and vegetables, rice, potatoes, with some meat and fruit. I can't stand most fat (most fatty acids taste like something rotting to me) and so I tend to have a very low fat intake. HCLF, effectively. I tend not to feel hunger much, so I use alarms to remind me when to eat. I'm active, I have stamina, and my biggest problem is keeping away from being dangerously underweight. When I diet I generally increase the meat/eggs/dairy amounts I eat in an attempt to gain some weight because I've gotten too thin. If I ate "as much as I feel like eating" I'd probably be grossly malnourished.
Different things work for different people. While it's true that no one can escape thermodynamics (if you eat less than you use, you'll lose weight) it's also true that if a diet is uncomfortable people won't stay with it. There's also the issue of bioavailability of the energy, the number of calories you actually get from a serving of food can't be more than what is measured by a calorimeter but it can be less.
