If you are in an air condioned flat you raise the temperature by having your computer in the flat. At the same time the regulation system that tracks the temperature will regulate against your intervention. The air conditoner will go on and reduce the temperature again.
IOW no net heat surplus is created. Air conditioners don’t violate the first law of thermodynamics.
You can say that “All people who create a calorie deficit via diet and exercise lose weight” is useless, that it is misleading, that it has wrong connotations, but you can’t say it is false (let alone “false in a trivial way”) unless there are people who create a calorie deficit via diet and exercise but don’t lose weight. (Note: “deficit” != “any expenditure”, “deficit” = “expenditure exceeding gains and savings”.)
