The simple version
Weight loss is usually driven by the trend over many days, not by one perfect day. A sustainable deficit should still leave room for protein, fiber, hydration, training, social meals, and normal life. If a target is so aggressive that you cannot follow it, the math may be “correct” but the plan is not useful.
