What part of claiming to be able to enjoy a chocolate bar if you eat otherwise healthy is a "lie"? It's only "unhealthy" in the context of your overall diet.
Would you say marmalade is healthy? It's certainly tasty. It has calories so in the context of starvation, it's absolutely healthy. What's so tacky about this is that there are only cynical reasons to discuss manifestly unhealthy candy in the context of a balanced diet. A candy bar has zero value in a balanced diet, like marmalade.
