In fact, this is such a stupid oversimplification that any amount of critical thinking can debunk it. There is a lot more to food that the net nutrition intake you have at the end of the day. The actual, physical composition of the food determines how quickly you body digests it, which in turn affects your energy levels, appetite, and mood. Your body does not digest apple juice the same way as it does raw apples, even if both have the same exact ingredients. You won't feel the same after a smoothie as you will after the same ingredients delivered raw. One method of intake gives you a short, high burst of energy followed by steeper drop off, while the raw form provides gentler changes and is less likely to spike your blood sugar.
All of this interacts with your psychology, your metabolism, and your physical and mental energy.
This is like saying I can safely fast for 4 days once If I eat 6000 calories worth of [insert food/drink] today. You might survive for 4 days but good luck not tearing up your body and feeling like a ghost by then.
More-processed foods are not inherently "bad" or "unhealthy", but they are inherently worse and less healthy than less-processed foods (generally). They contribute to shorter periods of feeling satiated and longer low-energy periods. You will crave processed food more frequently and in greater quantities than raw food.
