3. IF you work out in the afternoon or the evening, your body burns off the food and shit you ate and drank before it even has a chance to burn fat

Basically there are many reasons. It also depends on your goals. Do you want to lose fat? Gain muscle? Look presentable and not a fat shit? Be specific.
