However, not all calories are the same, metabolism is dynamic, and the brain is complex and exerts a powerful influence over behavior.
Increasing exercise will make you hungrier and most people are simply unable to resist this and end up not losing weight. It is why there is a common saying that "you cannot outrun your fork." Restricting calories generally is difficult in today's environment with plentiful calorie dense food everywhere. People don't cook as much as they used to and restaurant meals have more calories than ever.
AFAIK GLP-1 drugs work because they calm the minds desire to eat which is baked in deeply from millions of years of our ancestors struggling to get sufficient food.
When I was working out at Crunch (long after I got kicked out of that other gym) I would go across the street and get two tacos at Taco Bell which is good from the perspective of athletic performance because it puts back the glycogen you use and you'll use the protein to make muscle. But from an energy perspective it's close to neutral.
Muscle is good for you anyway in many ways, not least metabolic and in terms of mental health. I had an elite athlete workload back in the time I was trying to start a business based on foundation models about a decade early and it helped me keep it together though now I have

and my cardiologist told me to exercise less! I am still obese in terms of either BMI or fat percentage but I just saw a specialist for "medical weight loss" (e.g. Zepbound) I was told I had a huge lean body mass and that would help me lose weight. Wearing normal clothes I don't really look fat but in the wrong gym clothes next to the fit 20% of college students I have one hell of a gut.
You can’t really exercise enough to offset the food you can eat in a day, even if you somehow were able to dedicate all your time to exercising you would still have to limit your food intake.
Add to that the fact that exercise is mind numbingly boring and you have to conclude it is not a practical solution at all.
It's odd how people act as tho there's a "moral argument" against using a tool to help reach the goal. It feels a lot like the argument that "morals are from religion", as if you need god to know that murder isn't really a productive activity (unless you work in a slaughterhouse).
I wish American money could go back to having "mind your business" printed on it instead of "in god we trust", it was a huge loss to all of us when that garbage was passed. It was also a huge loss when everyone just decided to go along with saying "taxpayer money" instead of saying "public funds/money", but slippery psychological slopes are everywhere.
More importantly: I don’t want to eat less. I want to eat more. There is so much amazing food.
This is not true. There are plenty of activities that a healthy, enthusiastic person can do for quite a few hours per day that burn calories rapidly, and it takes serious effort to eat enough to offset the calorie usage. Think distance running, skiing, cycling, rowing, etc.
Sometimes people go to extreme technological measures to optimize their ability to consume calories (see recent record-setting marathon results). Sometimes people rely on extremely calorie-dense foods (butter, nuts, etc) so they can carry meals with them that are not wildly calorie-deficient for their long, unsupported travels.
When people are burning calories at this rate, they are probably not doing it for exercise — they’re probably either doing it because it’s fun or it’s part of an adventure.
I’m suspect that, if someone is overweight but in good enough shape to cross-country ski for six hours a day, then even if their body tends toward telling them to eat too much, they could probably lose weight by doing so for many days in a row.
Most people though will just eat more when they exercise, though dieticians say that more muscle is good for your metabolism and almost everybody would benefit from getting in some cardio and weights (i'm one of the rare exceptions who's been told to moderate my exercise, but I am the kind of person who can't understand how other people can make it through the day without going to the gym.)
People at the extreme end can struggle to eat enough food to maintain body condition, like I had a friend in college who trained for ultramarathons and you couldn't pinch anything on him even though he was eating all the time. Olympic swimmer Michael Phelps was a representative for the blockbuster heartburn medication Prilosec because he was burning 10,000 calories a day on his side!
People racing the Tour Divide, a 2700 mile solo unsupported bikepacking race through the Rocky Mountains, lose weight when riding their bikes 18 hours a day for 2-3+ weeks straight. They describe being unable to choke down enough food even though what they are eating is very calorie dense. Hotdogs, burritos, burgers, pizza, a pound of gummies every day, chocolate milk and ice cream when resupplying, McDonalds where they fill their hydration bladders with PowerAde, anything they can get their hands on quickly when they arrive at a small mountain town which frequently has nothing more than a gas station.

Obviously not a practical solution as you say but they do exercise enough to offset the food when eating as much as they can.
It’s not practical in the least for the average office worker to outrun the fork. It’s just silly advice and pointless to even bring up. When it takes an hour or more of treadmill work to cancel a single donut you don’t need to think about it any longer than that.
You exercise for health. Not to lose weight. Until you are at the margins and can consistently create an extra 100-200 calorie deficit by walking for an hour every evening or whatever.
My three gym days a week don’t do much for the scale. Those are for physical and mental health. The weight part is in the kitchen.
That doesn't make it an easy thing to do.
Fat people are aware of diet and exercise. They aren't stupid.
Until you have been chronically obese, or helped someone that is chronically obese, you don't understand that it is a deeply rooted subconscious issue, not a physics issue.
Fat people don't want to be fat, anymore than depressed people want to be sad. But something in their minds or bodies makes it non-optional. Pharmaceutical interventions change that thing.
When people - in their millions - say that this is the only effective thing, you could, I dunno, believe them. Or at least believe the pharmacological/medical science, which is, to circle back, all just physics.
