Maintaining the calorie expenditure of a 18 year old marine recruit isn’t practical for most people, however most people can boost their baseline metabolism and get light exercise which makes a huge difference.
However, ignoring what you eat and only considering how much is doomed to failure.
Pretty much every contestant on “Biggest Loser” gained the weight back because calorie restriction destroyed their base metabolism and they could not maintain the level of exercise required and hold down a job, care for a family, etc.
I lost 40 pounds several years ago and have had no trouble keeping it off. I don’t go hungry and I don’t spend several hours a day exercising. I eat like my parents and grandparents did before the medical community and department of agriculture sabotaged our diet.

They gained it back because they consumed more calories than they expended.
It would be impossible for there to be another cause.
It’s a binary and absolute axiom.
to say otherwise is enablement
