For sure. But I lost weight, a lot of it, by moving more or less the same and eating a lot more "caloric content" (switching from mostly carbs to mostly fat), which many people consider "violating thermodynamics", which is nonsense. If you don't change the ratios of your macros, and you don't make your expenditure vary much throughout the day, then -- yes, eat less, or move more.
